The U.S. faces an unwelcome combination of looming recession and persistent inflation that is reviving angst about stagflation, a condition not seen since the 1970s.
Inflation is rising. Yesterday the Labor Department said consumer prices in the U.S. jumped 0.4% in January and are up 4.3% over the past 12 months, near a 16-year high. Even stripping out sharply rising food and energy costs, prices rose 0.3% in January, driven by education, medical care, clothing and hotels. They are up by 2.5% from the previous year, a 10-month high.
The same day brought a reminder of possible recession. The Federal Reserve disclosed that its policy makers lowered their forecast for economic growth this year to between 1.3% and 2%, half a percentage point below the level of their previous forecast, in October. They blamed a further slowdown on the slump in housing prices, tighter lending standards and higher oil prices. They warned the economy's performance could fall short of even that lowered outlook.
Stocks fell on the Labor Department's morning inflation report. But shares rallied after the afternoon release of the minutes of the Jan. 29-30 meeting of Fed policy makers and their latest forecast for the economy. That's because investors took the Fed's darker outlook on growth to mean that it intended to cut its short-term interest rate next month at its next scheduled meeting.
A simultaneous rise in unemployment and inflation poses a dilemma for Fed Chairman Ben Bernanke. When the Fed wants to fight unemployment, it lowers interest rates. When it wants to damp inflation, it raises them. It's impossible to do both at the same time.
Stagflation, a term coined in the United Kingdom in 1965, defined the years from 1970 to 1981 in the U.S. Inflation rose to almost 15%. The economy went through three recessions. Unemployment reached 9%. Fed Chairman Paul Volcker finally conquered inflation, but only by dramatically boosting interest rates, causing a severe recession in 1981-82.
Today's circumstances are far from that. Inflation is lower. Unemployment has risen, but only to 4.9%. http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/
Yet there are similarities. As in the 1970s, surging commodity prices are leading the way. Crude oil rose to $100.74 a barrel yesterday, a new nominal high and close to its 1980 inflation-adjusted high. Wheat prices have hit a record. And, as in the 1970s, the rate at which the U.S. economy can grow without generating inflation has fallen, because of slower growth in both the labor force and in productivity, or output per hour of work.
The biggest difference is that in the 1970s, the Fed was unwilling, or thought itself unable, to bring inflation down. The Fed today sees achieving low inflation as its primary mission.
"The reason we're so unlikely to see a repeat is we're not adding irresponsible policy," says Christina Romer, an economist at the University of California at Berkeley and a historian of Fed policy. That means if the Fed is wrong in thinking inflation's recent rise is temporary, it will tolerate economic weakness in order to get inflation down again. "They'd have to let us suffer for a while." http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx
Indeed, in minutes to officials' Jan. 29-30 meeting, released yesterday with the customary three-week lag, some officials noted it was important not to lose sight of controlling inflation. They argued that "when prospects for growth had improved, a reversal of [some rate cuts], possibly even a rapid reversal, might be appropriate."
But that does not seem imminent. Officials said keeping interest rates low "appeared appropriate for a time," implying Fed officials felt little urgency to reverse recent cuts. Even after the January meeting's half-point rate cut, to 3%, "downside risks" to the economy remain, they said.
The inflation picture makes steep rate cuts a riskier way to rescue the economy than when former Fed Chairman Alan Greenspan delivered them in 2001. Stephen Cecchetti, an economist at Brandeis University, said the Fed is now torn between its dual responsibilities of keeping unemployment down and prices stable. "The primary objective has to be to shore up the financial markets" to protect the economy, he said. "Then, once you're finished, come back and start worrying about inflation."
Members of the Federal Open Market Committee, the Fed's policy committee, raised their forecasts for both the overall inflation rate and the "core" rate, which excludes food and energy, by 0.3 percentage points from October, their latest forecast revealed. Yet they dialed back their rhetorical concern. The officials pronounced risks on inflation to be "balanced" -- in other words, they felt inflation, should it differ from their forecast, was as likely to be lower as it was higher. In October, by contrast, they suggested that, if inflation was to differ from their forecast, they expected it to be higher. That's principally because they see unemployment remaining higher for longer than they did in October, and expect that to help contain price increases.
Higher inflation is still a possibility. Food and energy costs could keep rising, instead of flattening out as futures markets currently anticipate. Companies could succeed in passing those costs onto consumers.
Sara Lee Corp. this week told analysts it expects to recoup rising raw-material costs in part by raising prices, especially on bread. Company spokesman John Harris said Sara Lee's significant competitors had matched the increases, with consumers showing no sign of trading down to lower-cost brands. http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/"With commodities reaching unprecedented levels," Mr. Harris said, "it is quite likely we will take pricing up again."
Goodyear Tire & Rubber raised the price of replacement tires 7% on Feb. 1, on top of two increases totaling 11% last year. Chief Financial Officer Mark Schmitz told analysts last week that the hike was the result of rising prices of key raw materials, according to a transcript by Thomson Financial. Mohawk Industries Inc. raised carpet prices in December and again in January because of rising material costs, even though sales have been hurt by the slumping housing market.
The declining dollar, while boosting U.S. exports, is adding to inflation pressure, as goods priced in foreign currencies become relatively more expensive. Prices for imports from China jumped 0.8% in January, the largest monthly increase since the Labor Department began reporting the data in 2003.
British Parliamentarian Iain Macleod is credited with first using the word stagflation in 1965. "We now have the worst of both worlds -- not just inflation on the one side or stagnation on the other, but both of them together. We have a sort of 'stagflation' situation."
In the U.S., stagflation scares are more common than actual stagflation. Core inflation rose after the start of recessions in both 1990-91 and 2001, but then trended down as unemployment kept rising.
The only generally agreed period of stagflation in the U.S. came in the 1970s. Its seeds were planted in the late 1960s, when President Johnson revved up growth with spending on the Vietnam War and his Great Society programs. Fed Chairman William McChesney Martin, meanwhile, failed to tighten monetary policy sufficiently to rein in that growth.
In the early 1970s, President Nixon, with the acquiescence of Fed Chairman Arthur Burns, tried to get inflation down by imposing controls on wage and price increases. The job became harder after the Arab oil embargo dramatically drove up energy prices, and overall inflation, in 1973. http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx Mr. Burns persistently underestimated inflation pressure: In part, he did not realize the economy's potential growth rate had fallen, and that an influx of young, inexperienced baby boomers into the work force had made it harder to get unemployment down to early-1960s levels.
As a result, even when he raised rates, pushing the economy into a severe recession in 1974-75, inflation and unemployment didn't fall back to the levels of the previous decade. Mr. Burns and his colleagues wrongly concluded inflation no longer responded to the condition of the economy, said Ms. Romer, the Berkeley economist. "They didn't know how the world worked," she said.
In a speech in 1979, a year after he stepped down, Mr. Burns blamed his failure on a political environment that wouldn't tolerate the high interest rates necessary to rein in inflation. As the Federal Reserve tested how far it could raise rates, he said, "it repeatedly evoked violent criticism" from the White House and Congress.
Such political risks are smaller but not entirely absent for Mr. Bernanke in this election year. On Sunday, the likely Republican presidential candidate, Sen. John McCain, told ABC's "This Week": "I would have liked to have seen faster rate cuts and earlier than they were done by him." Asked if he would reappoint Mr. Bernanke when his term expires in 2010, Sen. McCain said, "I would have to consider that at the time."
Still, Mr. Bernanke has reiterated the importance of not repeating the 1970s. He and his colleagues believe a persistent escalation of inflation is likely only if workers and firms come to expect the elevated inflation rate to persist, and set their wages and prices accordingly.
"Any tendency of inflation expectations to become unmoored -- or for the Fed's inflation-fighting credibility to be eroded -- could greatly...reduce the central bank's policy flexibility" to support growth with lower interest rates, he told Congress last week.
That credibility could be endangered by the Fed's recent track record. Yesterday's forecasts show that FOMC members define price stability as inflation of 1.5% to 2%, measured by an index that differs slightly from the commonly cited consumer-price index. http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/ By that measure, inflation has averaged 2.8% since mid-2004, when oil began a multiyear surge. Core inflation, which excludes food and energy, has averaged 2.2%.
Thus far, Fed officials have taken comfort that surveys and bond-market behavior suggest the public expects the inflation rate to fall. But expected inflation, as measured by trading of inflation-protected Treasury bonds, has jumped since the Fed declared in early January that supporting growth would be a more important focus than holding down inflation. (Fed officials believe technical details in the way the bonds trade may explain some of the jump.) And professional forecasters surveyed by the Federal Reserve Bank of Philadelphia recently nudged up their expected inflation rate for the next 10 years to 2.5% from 2.4%, where it had stood all last year.
On the other hand, surveys of consumer predictions about inflation show no corresponding jump. And most important, wage gains have not accelerated. Since labor is the largest component of business costs, a wage-price spiral would likely be a prerequisite for stagflation.
"We're a very, very long way from the 1970s," former Treasury Secretary Lawrence Summers said in an interview yesterday. A hit to overall spending, as has resulted from the current tightening of lending conditions, first affects production and employment, and only later inflation, he said. "But obviously, inflation figures need to be monitored very closely."
Six nights a week, Guo Bairong takes the stage at the Xanadu Lounge at the Sands Macau casino. As players place their bets at nearby tables, he opens with a popular love song in Mandarin, closing his eyes as he sways with the music. Slipping effortlessly into Cantonese, he launches into another number.
Crowds gather not only to hear his singing, which is mellifluous, but also to gape: Guo Bairong is also known as Barry Cox, a Caucasian, former waiter and supermarket cashier from Liverpool, England, whose only formal study of Cantonese was at a British community center.
Mr. Cox's quirky act -- sandwiched between cabaret dance performances like the scantily clad Glamour Girls in glittery outfits and red elbow-length gloves and authentic Chinese crooners such as Hua D, is among the spectacles on Macau's emerging entertainment scene.
Macau's clutch of new casinos has quickly outpaced the Las Vegas strip in gambling revenue, raking in some $10 billion last year. But the former Portuguese colony has to up its game to compete with its American counterpart as an all-around tourism destination. Key to that growth is the territory's entertainment scene, which pales in comparison to the A-list performers in Las Vegas, such as Bette Midler and Cher, who have regular gigs.
A few years ago, Macau was a sleepy coastal town. Visitors came for the fresh fish and Vinho Verde, the cobblestone streets and musty antique shops -- and for the gambling. The city became a special administrative zone when it was returned to China in 1999, making it the only place in China where casinos are legal.
It all began to change after 2002, when the Beijing-backed Macau government ended local tycoon Stanley Ho's monopoly on the territory's gambling by issuing licenses to other companies, including the Vegas casino Wynn Resorts. MGM Mirage, Crown Ltd. from Australia and others soon piled in.
Around the same time, China began to ease its restrictions on individual travel to Hong Kong and Macau. http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx A flood of tourists poured in from the mainland to try their luck. About 10.5 million visited Macau in 2005; that figure is expected to jump to nearly 15 million next year, according to the Pacific Asia Travel Association, a trade group.
But how to entertain this growing crowd? When the new casinos began opening in 2004, the prevailing logic among casino executives was that the Chinese visitors mostly come to gamble. Some operators are still unsure what entertainment to offer, especially performances that guests would have to pay for as opposed to the complimentary shows available on the gambling floors.
"This is a very new market," says a Wynn Macau spokeswoman, adding that "we're not sure how the market would respond" to big global acts that visitors would have to shell out for.
Wynn casino's current entertainment options are limited to a five-minute water and light show set to music, and an attraction known as the Tree of Prosperity. The 11-meter tall golden tree, which Wynn Macau says is an auspicious symbol, sits in the casino's atrium.
At the Crown Macau, "we're focusing on offering a six-star experience," says Charles Ngai, a Crown spokesman. Apparently that doesn't include entertainment; the hotel-casino has a spa, eight restaurants and two bars, but no performances on offer.
It's a different story at Mr. Ho's Grand Lisboa, where there are two shows: a free, daily "Crazy Paris" performance -- a can-can-style dance act performed by Western women, and "Tokyo Nights," performed by a troupe of Japanese dancers, which costs $31.
"No one really knows what people are looking for here," says Jennifer Welker, the Macau-based author of "The New Macau." "They're still in that testing phase of trying to suss out what people really like." Many of the guests at the Sands, for instance, she says, seem most interested in gambling and aren't willing to pay for a show. http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/"The Venetian might need to host more Chinese acts to appeal to the mainland tourists," she adds.
Macau's entertainment limitations aside, the territory already is giving neighboring Hong Kong a run for its money. Many big-name acts have chosen to play in Macau rather than Hong Kong recently. Last October, for instance, the U.S. National Basketball Association's Orlando Magic, the Cleveland Cavaliers and the China Men's National Team played at the Venetian Arena, the 15,000-seat stadium at the Venetian resort and casino. The same month, hip-hop stars the Black Eyed Peas brought a crowd of more than 10,000 to its feet there. The Police performed in Macau in early February, and Celine Dion arrives next month for a one-night-only show as part of her world tour.
Hong Kong has the facilities to compete: In addition to the cavernous convention center hall in the Wanchai area that big-name acts traditionally use, the territory has the newer AsiaWorld-Arena, a 13,500-seat concert venue next to the airport. But economics may play a role in the migration of big acts to Macau. Min Yoo, a Shanghai- and Hong Kong-based concert promoter, says it is cheaper to put on a large event in Macau than in Hong Kong.
In any case, Macau still has a few wrinkles to iron out. For starters, it isn't always easy to know what events are on.
Strict rules against advertising by casinos in mainland China make it impossible to promote events there. Even in Hong Kong, says Mark Brown, president of the Sands Macau and Venetian Macau, advertising for events has to be planned carefully, considering the potential sensitivity around the idea of gambling.
What's more, Macau's transportation infrastructure is lacking. A taxi shortage means fans arriving on the ferry from Hong Kong often have to wait in long lines for a shuttle bus to the Venetian Arena.
For now, the Venetian and its sister property, the Sands, are where the serious entertainment action is. This summer, the Venetian plans to bring Cirque du Soleil, the acrobatic show that's a fixture in Las Vegas, to Macau as a permanent show with 10 performances a week. Cirque will perform in a 1,800-seat theater that is still under construction. http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/That's only the beginning. "Every top U.S. name you can think of, we have an offer out there," says Mr. Brown. "Every top Asian artist, we have an offer out there. Every type of sport you can think of...we have an offer out there."
Meantime, acts like Mr. Cox's are filling the gap.
As a high-school student, Mr. Cox watched Jackie Chan movies and fell in love with the Canto-pop soundtracks. He took a few Cantonese lessons and discovered he had a flair for Asian languages -- he's never studied Mandarin formally, though he considers himself fluent in both.
So he quit his job as a salesman in a Liverpool electrical store and started waiting tables in a Chinese restaurant to hone his language skills. Eventually, he began performing at Chinese gatherings in Liverpool. His renditions of popular Canto-pop classics such "Kiss Under the Moon" and "Love Once More" won over the immigrant crowds there, turning him into a local celebrity.
But all along, his dream was to make it big in Asia. And so in 2002, he moved to Hong Kong, where he sang at corporate events and Christmas parties. He even traveled in mainland China doing a few performances in discos in places like Shenzhen and Guangzhou.
Then, six months ago, Mr. Cox, whose Chinese name was given to him by his Chinese-language headmaster, left Hong Kong for the lights of Macau. http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/"It's good for what I'm doing," he says, in his Liverpudlian accent. I'm "partly living the dream," he adds.
On a chilly Saturday night, as the Black Eyed Peas warmed up at the Venetian Arena, Mr. Cox, dressed entirely in black down to his pointy-toed shoes, was warming up his audience. Gamblers at nearby slot machines had fallen still, their jaws slack at the spectacle of a foreigner singing Canto-pop. A woman was dancing in her chair.
"This one's for you," he said in Mandarin to a Chinese couple in the crowd, as he launched into a number by Deng Lijun, a Taiwanese singer popular in the 1970s and '80s. The lounge, filled with mainland and Taiwanese tourists, exploded into applause.
Dates of the Old Kingdom of Ancient Egypt: The Old Kingdom ran from about 2686-2160 B.C. It started with the 3rd Dynasty and ended with the 8th (some say the 6th).
* 3rd: 2686-2613 B.C. * 4th: 2613-2494 B.C. * 5th 2494-2345 B.C. * 6th: 2345-2181 B.C. * 7th and 8th: 2181-2160 B.C.
Before the Old Kingdom was the Early Dynastic Period, which ran from about 3000-2686 B.C.
Before the Early Dynastic Period was the Predynastic which began in the 6th millennium B.C.
Earlier than the Predynastic Period were the Neolithic (c.8800-4700 B.C.) and Paleolithic Periods (c.700,000-7000 B.C.).

Old Kingdom Capital: During the Early Dynastic Period and Old Kingdom Egypt, the residence of the pharaoh was at White Wall (Ineb-hedj) on the west bank of the Nile south of Cairo. This capital city was later named Memphis.
After the 8th Dynasty, the pharaohs left Memphis. Turin Canon: The Turin Canon, a papyrus discovered by Bernardino Drovetti in the necropolis at Thebes, Egypt, in 1822, is so-called because it resides in the northern Italian city of Turin at the Museo Egizio. The Turin Canon provides a list of names of the kings of Egypt from the beginning of time to the time of Ramses II and is important, therefore, for providing the names of the Old Kingdom pharaohs.
For more on the problems of ancient Egyptian chronology and the Turin Canon, see Problems Dating Hatshepsut. Step Pyramid of Djoser: The Old Kingdom is the age of pyramid building beginning with Third Dynasty Pharaoh Djoser's Step Pyramid at Saqqara, the first finished large stone building in the world. Its ground area is 140 X 118 m., its height 60 m., its outside enclosure 545 X 277 m. Djoser's corpse was buried there but below ground level. There were other buildings and shrines in the area. The architect credited with Djoser's 6-step pyramid was Imhotep (Imouthes), a high priest of Heliopolis.

Old Kingdom True Pyramids: Dynasty divisions follow major changes. The Fourth Dynasty begins with the ruler who changed the architectural style of the pyramids.
Under Pharaoh Sneferu (2613-2589) the pyramid complex emerged, with the axis re-oriented east to west. A temple was built against the eastern side of the pyramid. There was a road running to a temple in the valley that served as entrance to the complex. Sneferu's name is connected with a bent pyramid whose slope changed two-thirds of the way up. He had a second (Red) pyramid in which he was buried. Sneferu's son Khufu (Cheops) built the Great Pyramid at Giza. About the Old Kingdom Period: The Old Kingdom was a long, politically stable, prosperous period for ancient Egypt. Government was centralized. The king was credited with supernatural powers, his authority virtually absolute. Even after death the pharaoh was expected to mediate between gods and humans, therefore preparation for his afterlife, the building of elaborate burial sites, was vitally important.
Over time, the royal authority weakened while the power of viziers and local administrators grew. The office of overseer of Upper Egypt was created and Nubia became important because of contact, immigration, and resources for Egypt to exploit. http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx
Although Egypt had been self-sufficient with its bountiful annual Nile inundation allowing farmers to grow emmer wheat and barley, building projects like the pyramids and temples led the Egyptians beyond its borders for minerals and manpower.
The sun god Ra grew more important through the Old Kingdom Period with obelisks built on pedestals as part of their temples. A full written language of hieroglyphs was used on the sacred monuments, while hieratic was used on papyrus documents.
Although their lifetimes span billions of years, galaxies age, just like people. As rambunctious young’uns, they undergo bursts of star formation that create hot blue orbs out of the simple elements hydrogen and helium. As galaxies grow older, they settle down. Not only do their stars cool and become redder, but they eventually burn out and die, releasing into the galaxy heavier elements that formed in the stellar furnaces.
So astronomers have been repeatedly baffled by a peculiar, developmentally challenged galaxy called I Zwicky 18. When they first sighted it about 40 years ago, they thought it was a not-quite-billion-year-old toddler brimming with hot young stars, full of hydrogen and helium and possessing very few heavy elements, called metals. Finding such a young galaxy near others that are at least 7 billion years old thrilled—and perplexed—the scientists. But new observations from NASA’s Hubble Space Telescope have revealed ancient stars mingled with the young ones, proving the galaxy as a whole is in fact as old as its neighbors. advertisement | article continues below
Astronomers don’t know why this galaxy is so low on metals, or why it’s forming so many new stars so late in the game. It’s possible that this relatively light galaxy has too little mass—or gravitational pull—to retain the metals, and that a rush of gas called a galactic wind swept them away. Or maybe the galaxy’s relatively isolated position caused it to develop slowly: There are few other galaxies around to help seed star formation.
They also don’t know why it’s not happening in all dwarf galaxies. “It’s possible that there are more out there like this,” says Francesca Annibali, http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/an astronomer at the Space Telescope Science Institute in Baltimore, who worked on the project. “If they are more common, then that means that some process is inhibiting star formation in small, low-metal environments.” Whatever the cause of I Zwicky 18’s strange history, its close resemblance to primordial galaxies offers a unique opportunity to study how stars acted in the early universe, something that normally cannot be observed at such close range.
For astronauts toiling in the close quarters of the International Space Station or on a shuttle to Mars, an ordinary germ would be risky enough. But a recent experiment published in the Proceedings of the National Academy of Sciences has shown that a microbe can turn even more dangerous in space than on Earth. In that study, a bacte–rium particularly nasty for humans—salmonella—was shown to become more virulent after just 83 hours of growing in space.
The experiment on the space shuttle Atlantis was designed to explore how a lack of gravity affects disease-causing microbes in space. Astronauts aboard the space shuttle grew the salmonella, and back on Earth researchers used it to infect a group of mice. For comparison, bacteria grown in a laboratory on Earth in normal gravity infected another group of mice. The mice infected with the space-grown germs had a mortality rate almost three times higher than that of mice given germs grown in normal gravity.
Researchers noticed that while on board the space shuttle, the salmonella encased themselves in a biofilm, a protective coating that is notoriously resistant to anti–biotics. Several follow-up experiments on space http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/shuttle flights over the next few years will look to see whether other bacteria undergo similar changes in virulence in microgravity.
By now you’ve probably heard about the lunar eclipse tomorrow night. Lunar eclipses are great; they last a long time, so there’s no hurry, you don’t need crystal clear skies (the clearer the better, of course), and you don’t need a telescope! Just your eyes will do, though having binoculars is better. I actually prefer them over using a telescope.
The event will be visible pretty much everywhere in the US, Canada, South America, and western Africa and Europe. Orbiting Frog has a ton of info, including a nice animation of what to expect. Sky and Telescope has info as well (including a diagram with times listed for the west coast of the US, if that helps). But here’s the rundown: The show starts for real around 01:43 Universal Time (CAREFUL HERE! That’s 1:43 a.m. on Thursday morning in England, but that’s Wednesday night for the United States. Check to see what your local offset is from Universal Time; for example, in Boulder we are UT - 7, so the eclipse starts here at 1:43 a.m. UT - 7 hours = 6:43 p.m. local time Wednesday night. http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx But don’t trust me– do this math for yourself!). You may read that the eclipse starts an hour or so before that, but if you look you probably won’t see anything. Earth casts a dark shadow surrounded by a much lighter one, called the umbra and penumbra, respectively. When the Moon enters the penumbra you’ll hardly notice, but when it enters the umbra at 01:43 it’ll look like a bite is taken out of it. 1 hour 20 minutes later (03:00 UT) the Moon will be totally engulfed in the Earth’s shadow. It may take on a brown or reddish appearance, depending on various factors like pollution in our atmosphere. Sometimes the Moon turns blood red, and it’s really amazing. I have found that the Moon appears to really be a globe when this happens; I assume it’s an illusion of some kind but the effect can be overwhelming. The totality phase of the eclipse will last for about 51 minutes, and then it will start to leave the umbra, and you’ll see a bright crescent begin to form. By 05:10 UT it’ll all be over, and the Moon will look normal again. I plan on being at The Little Astronomer’s school, since they’re hosting a party in the parking lot to see it. There are no doubt viewings all over the place, so call your local astronomy club, museum, or even news station to see what’s going on in your area. This is the last total lunar eclipse for the US until very late in 2010, so I hope you get a chance to see it!
The Code of Hammurabi is one of the earliest known law codes and was probably compiled at the start of the reign of the Babylonian king Hammurabi (1792–1750 B.C.). The Code of Hammurabi is famous for demanding punishment to fit the crime (the lex talionis, or an eye for an eye) with different treatment for each social class. The Code is thought to be Sumerian in spirit but with a Babylonian inspired harshness. Its laws cover land tenure, rent, the position of women, marriage, divorce, inheritance, contracts, control of public order, administration of justice, wages, and labor conditions. (See LOC article on Iraq.) The prologue of the Code give a glimpse of the relationship between the Babylonian gods and kings.
A 2.3 m high diorite or basalt stele of the Code of Hammurabi was found at Susa, Iran, in 1901. At the top is a bas relief image. The text of laws is written in cuneiform. This stele of the Code of Hammurabi is at the Louvre.

Go to Other Ancient / Classical History Glossary pages beginning with the letterSilbury Hill, a 4,400-year-old, 130-foot-high mound of chalk and dirt about 80 miles west of London, has finally yielded its ancient secrets. It is not the tomb of the long-forgotten King Sil nor the resting place of a golden knight. And it is not, despite the folklore, a dumping ground for the devil’s dirt, forced to drop there by the magic of priests. The story behind the mysterious hill is much less colorful. http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/Silbury Hill is a shrine filled with rocks that, for Stone Age Britons, probably represented the spirits of ancient ancestors.
The physical excavation (video) of Silbury Hill, along with studies using ground-penetrating radar and seismic sonar equipment, has shown that there is not a single human bone in the mound. Instead, dozens of sarsen stones, a type of sandstone that is also used for Neolithic stone circles like Stonehenge, are buried there.
Local geologists think that during the Stone Age, the landscape around Silbury Hill contained hundreds of thousands of sarsen stones. Because the area is made mainly of chalk, prehistoric people would have seen no apparent natural origin for the stones. Archaeologists think the locals endowed these rocks with a spiritual importance that Silbury Hill still embodies. The area itself is considered sacred by modern pagans, who still make offerings at a nearby spring. Due to conservation laws, the prehistoric holy hill is out-of-bounds to pagans and tourists alike.
Kosovo won the recognition of the United States and its biggest Western European allies Monday, while earning rebukes and rejections from Serbia, Russia and a disparate mix of states the world over who face their own separatist movements at home.
One day after the tiny Balkan province declared its independence, the world had its chance to choose sides. While some countries had made their decisions months in advance, that did not diminish the drama of whether a newly birthed nation would be welcomed into the fold or rejected.
Major European powers, including France, Germany and Britain, along with the United States, officially recognized Kosovo, even as officials took pains to point out that it should not serve as an invitation or precedent for other groups hoping to declare independence. That is because one of the biggest unknowns remains whether Kosovo’s declaration could rekindle conflicts elsewhere, including in ethnically divided Bosnia.
As a result, the reverberations were felt from Russian-backed enclaves in Georgia to the Taiwan Strait. Spain, a member of the European Union and one of the countries with soldiers in the NATO force in Kosovo, refused its recognition. Yet Turkey, despite its history of conflict with Kurdish separatists, chose to support Kosovo’s independence.
In a letter to Kosovo’s president, Fatmir Sejdiu, President Bush wrote: “On behalf of the American people, I hereby recognize Kosovo as an independent and sovereign state. I congratulate you and Kosovo’s citizens for having taken this important step in your democratic and national development.”
In an apparent conciliatory gesture, Secretary of State Condoleezza Rice said in her own statement, “The United States takes this opportunity to reaffirm our friendship with Serbia, an ally during two world wars.”
But Prime Minister Vojislav Kostunica of Serbia, which has regarded Kosovo as its heartland since medieval times, vowed that Serbia would never recognize the “false state.” http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx Mr. Kostunica recalled Serbia’s ambassador to Washington, wire services reported. The State Department had no comment on those reports on Monday evening.
At the United Nations, Boris Tadic, Serbia’s president, told the Security Council that the declaration of independence “annuls international law, tramples upon justice and enthrones injustice.” He asked that Secretary General Ban Ki-moon direct the United Nations mission chief in Kosovo to declare the action “null and void” and to dissolve the Kosovo Assembly, which adopted the declaration on Sunday.
Addressing the Council before Mr. Tadic spoke, Mr. Ban said the United http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/Nations administration, approved by the Council in 1999, would continue to run Kosovo until a formal transition could be arranged.
European foreign ministers meeting in Brussels appeared to reach a minimal common position, acknowledging that Kosovo had declared independence and allowing those nations that wanted to recognize it formally to do so.
Bernard Kouchner, France’s foreign minister, said the declaration was “a victory for common sense,” and pointed to what he hoped would be future reconciliation between Serbia and Kosovo. “I don’t know at what date, in which year, but Kosovo and Serbia will be together in the European Union,” he said.
However, the foreign minister of Spain, Miguel Ángel Moratinos, told reporters that the declaration did not respect international law and that Spain would not recognize Kosovo. “The government of Spain will not recognize the unilateral act proclaimed yesterday by the Assembly of Kosovo,” Reuters quoted him as saying.
Among European Union members, Cyprus, Romania and Slovakia have also been reluctant to recognize Kosovo.
Diplomatic recognition is more than just a popularity contest for Kosovo, a desperately poor, predominantly Muslim landlocked territory of two million. It needs the help and support of international institutions if it expects to improve its dire economic condition. A United Nations protectorate since 1999, it is policed by 16,000 NATO troops and has an unemployment rate of around 60 percent and an average monthly wage of $250.
“We will be working with the government to try to help it politically as well as economically,” said R. Nicholas Burns, the under secretary of state for political affairs, in a conference call with reporters on Monday, pointing out that the United States gave $77 million in aid to Kosovo in 2007 and would raise that amount to roughly $335 million in 2008.
Mr. Burns, who said he had consulted by phone with European counterparts after the meeting of European Union foreign ministers, said there would be a donor conference in Europe in the coming months to encourage additional aid, and hoped there could be debt relief for Kosovo as well as strong regional trade opportunities.
Russia, which opposes Kosovo’s independence, demanded an emergency meeting of the United Nations Security Council on Sunday to proclaim the declaration “null and void,” but the meeting produced no http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/ resolution. The Security Council agreed to a request by Russia and Serbia to hold the open meeting on Monday that Mr. Tadic addressed.
Mr. Burns said he did not foresee trouble with Russia. “I do not expect any kind of crisis with Russia over this,” he said. “I expect Russia to be supportive of stability in this region.”
But in Moscow, the upper and lower houses of Parliament on Monday released a joint statement signaling an intention to recognize at least two Russian-backed separatist areas in the former Soviet Union — Abkhazia and South Ossetia, both in Georgia.
Abkhazia and South Ossetia have announced their intention to seek recognition as independent states. Russia has already granted citizenship to most residents of both enclaves and had hinted that it might recognize their independence if Western countries recognized Kosovo.
“The right of nations to self-determination cannot justify recognition of Kosovo’s independence along with the simultaneous refusal to discuss similar acts by other self-proclaimed states, which have obtained de facto independence exclusively by themselves,” the Russian Parliament’s statement read.
Georgia disputes the claim that the regions have obtained independence by themselves. The areas broke from Georgia after brief wars in the 1990s, and have survived with Russian support.
Eduard Kokoity, the Ossetian president, said Monday that the two breakaway regions would submit a request for recognition to Russia’s Parliament by the end of the month, the Interfax news agency reported.
But experts and officials said they did not expect simmering conflicts to break out into significant violence as a result of Kosovo’s declaration. “These are emotional reactions that I think are transitory and can be contained,” said Peter Semneby, the European Union’s special representative for the South Caucasus, in a telephone interview from Georgia. “It’s very much in the interest of major actors to try to contain them.”
On the other side of the world, China, Indonesia and Sri Lanka also criticized Kosovo’s http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/declaration of independence, while Taiwan and Australia welcomed it, as Kosovo’s move appeared to be a litmus test of attitudes in Asia toward secession.
The Beijing government, which has threatened military action if Taiwan declares formal independence, voiced “grave concern” over Kosovo’s action.
“China is deeply worried about its severe and negative impact on peace and stability of the Balkan region and the goal of establishing a multiethnic society in Kosovo,” said Liu Jianchao, a Chinese Foreign Ministry spokesman.
The province of Kosovo declared independence from Serbia on Sunday, sending tens of thousands of ethnic Albanians streaming through the streets to celebrate what they hoped was the end of a long and bloody struggle for national self-determination.
Kosovo’s bid to be recognized as Europe’s newest country — after a civil war that killed 10,000 people a decade ago and then years of limbo under United Nations rule — was the latest episode in the dismemberment of the former Yugoslavia, 17 years after its dissolution began.
It brings to a climax a showdown between the West, which argues that Serbia’s brutal subjugation of Kosovo’s ethnic Albanian majority cost it any right to rule the territory, and the Serbian government and its allies in the Kremlin. http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx They counter that Kosovo’s independence is a reckless breach of international law that will spur other secessionist movements across the world.
As Albanians danced in the streets and fired guns in the air in the capital, Pristina, international reaction was sharply divided, suggesting that the clash between the principles of sovereignty and self-determination was far from resolved.
Britain, France and Germany were expected to be the first to recognize the new nation as early as Monday, while other nations, fearing separatist movements within their own borders, have said they will refuse. Russia demanded an emergency meeting of the United Nations Security Council to proclaim the declaration “null and void,” but the meeting produced no resolution.
The United States and additional European Union member states were expected to recognize Kosovo’s independence in the coming days.
President Bush, speaking in Tanzania, said the United States would continue to work to prevent violence in Kosovo, while reaching out to Serbia. He said that resolving the conflict in Kosovo was essential to stability in the Balkans and that “the Serbian people can know that they have a friend in America.”
In declaring independence, Kosovo’s prime minister, Hashim Thaci, a former leader of the guerrilla force that just over 10 years ago began an armed rebellion against Serbian domination, struck a note of reconciliation. Addressing Parliament in both Albanian and Serbian, he pledged to protect the rights of Kosovo’s Serbian minority. “I feel the heartbeat of our ancestors,” he said. “We, the leaders of our people, democratically elected, through this declaration proclaim Kosovo an independent and sovereign state.”
Kosovo, a desperately poor, predominantly Muslim landlocked territory of two million, has been a United Nations protectorate since 1999, policed http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/by 16,000 NATO troops. Its unemployment rate is about 60 percent and average monthly wage is $250.
Electricity is so undependable that lights go out in the capital several times a day. Corruption is rife and human trafficking threatens to entrench a lawless state on Europe’s doorstep.
Ethnic Albanians from as far away as the United States poured into Pristina over the weekend, braving freezing temperatures and heavy snow to dance in frenzied jubilation. Beating drums, waving Albanian flags and throwing firecrackers, they chanted: “Independence! Independence! We are free at last!”
A 100-foot-long birthday cake was installed on Pristina’s main boulevard.
In an outpouring of adulation for the United States, the architect of NATO’s 1999 bombing campaign against Serbian forces under President Slobodan Milosevic, revelers unfurled giant American flags, carried posters of former President Bill Clinton and chanted, “Thank you, U.S.A.” and “God bless America.”
Hundreds of people, many waving Albanian flags, celebrated in Times Square. Revelers in cars drove in circles around the area, leading chants whenever they passed the crowds gathered on the sidewalks.
That spirit of exaltation contrasted sharply with the despair, anger and disbelief that gripped Serbia and the Serbian enclaves of northern Kosovo. In Belgrade, http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx Serbia’s capital, as many as 2,000 angry Serbs converged on the United States Embassy, hurling stones and smashing windows.
In the Kosovo Serb stronghold of Mitrovica, a grenade was thrown at a United Nations building, the police said. No one was injured.
Vojislav Kostunica, the prime minister of Serbia, which has regarded Kosovo as its heartland since medieval times, vowed that Serbia would never recognize the “false state.”
In an address on national television on Sunday, he said Kosovo was propped up unlawfully by the United States and called the declaration a “humiliation” for the European Union. The Serbian government has ruled out using military force in response, but was expected to downgrade diplomatic ties with any government that recognized Kosovo.
Demonstrations were planned for Monday in Serbian enclaves across Kosovo. Serbs said they were under orders from Belgrade to ignore the independence declaration and remain in Kosovo to keep the northern part of the territory under de facto Serbian control, raising questions about Serbia’s long-term aims.
At the Security Council, Russia argued that the proclamation violated the 1999 resolution that established the United Nations mission in Kosovo. “Our position is that the declaration should be disregarded by the international community and declared null and void,” said Vitaly I. Churkin, Russia’s ambassador to the United Nations.
But Alejandro D. Wolff, the deputy American ambassador, said, “In our view, this declaration is logical and consistent and completely in line with” the 1999 measure.
Secretary General Ban Ki-moon pleaded with all parties “to refrain from any actions or statements that could endanger peace, incite violence or jeopardize security in Kosovo or the region.”
The Security Council agreed to a request by Russia and Serbia to hold an open meeting on Monday that will be addressed by the Serbian president, Boris Tadic.
Kosovo’s declaration followed nearly two years of United Nations-sponsored negotiations between it and Serbia. Those talks failed, as did a Security Council effort in December to resolve Kosovo’s future.
The European Commission, the European Union’s executive branch, appealed for calm, while NATO’s secretary general, Jaap de Hoop Scheffer, said the alliance would respond “swiftly and firmly against anyone who might resort to violence.”
Kosovo’s sovereignty remains severely circumscribed, making it reliant on the international community. NATO still provides international security, while the European Union has agreed to send an 1,800-strong http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/ police and judicial mission to help run the territory after the United Nations leaves.
Ulrich Wilhelm, the spokesman for the German chancellor, Angela Merkel, said Germany would decide what to do on Monday.
Kosovo played a central role in the collapse of the Yugoslav federation built by the Communist strongman Josip Broz Tito, who died in 1980. Albanian nationalism erupted in Kosovo in 1981, leading to bloody clashes.
In the 1980s, Mr. Milosevic used Serbs’ enormous sense of grievance that their ancestral heartland was now dominated by Muslim Albanians to come to power in Serbia. By 1989, he had abolished Kosovo’s autonomy, fired tens of thousands of Albanians from their jobs, suppressed Albanian language education and controlled the territory with a heavy police presence.
Ten years ago, Mr. Milosevic’s forces moved against the rebel Kosovo Liberation Army, killing a guerrilla leader and his family at their compound. As violence escalated, NATO intervened in a 1999 bombing campaign, causing hundreds of thousands of Albanians and Serbs to flee.
An estimated 10,000 civilians were killed in the 1998-99 conflict, many of them Albanians, while 1,500 Serbs died in revenge killings that followed.
For the ethnic Albanians who make up 95 percent of Kosovo’s population, independence marks a new beginning.
“Independence is a catharsis,” said Antoneta Kastrati, 26, an Albanian from Peja, who said her mother and older sister were killed by their Serbian neighbors in 1999. “Things won’t change overnight and we cannot forget the past, but maybe I will feel safe now and my nightmares will finally go away.”
In Mitrovica, a 70-year-old Serbian engineer who would give only his first name, Svetozar, said: “I will stay here forever. This will always be Serbia.”
Kosovo’s declaration created immediate ripples in the former Soviet Union, where small, Russian-backed separatist areas — one in Moldova and two in the republic of Georgia — have existed since the early 1990s. http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/Two of them — Abkhazia and South Ossetia in Georgia — announced their intention to seek recognition as independent states.
Conversely, several of the European Union’s 27 member states — including Spain, Greece, Cyprus, Slovakia and Romania — oppose recognizing Kosovo because they fear encouraging secessionist movements within their own borders.
In Brussels, officials were drafting a statement for a foreign ministers’ meeting on Monday. Senior European Union officials said they expected it to acknowledge Kosovo’s independence declaration without http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/explicitly endorsing it.
The declaration of independence raises the prospects of a new constitution and emblems of nationhood, including a new flag bearing a map of Kosovo topped by six stars.
But in a sign of how hard it will be to forge the kind of multiethnic, secular identity that foreign powers have urged, the distinctive two-headed eagle of the red and black Albanian flag, reviled by Serbs, was everywhere Sunday, held by revelers, draped on horses, flapping out of car windows and hanging outside homes and storefronts across the territory.
Warren Hoge contributed reporting from the United Nations, C. J. Chivers from Moscow and Nicholas Kulish from Berlin.
It’s a rare political race where particle physics might come up, but IL-14, Denny Hastert’s former seat, is just such a delightful intersection. And Bill Foster is that Heinlein-esque synthesis; a businessman who started the firm that revolutionized theatre lighting and invented the Source 4 ellipsoidal reflector spotlight, turned award winning physicist, and now candidate.
To appreciate what kind of congressman Foster might become, it’s worth considering what kind of primary campaign he ran: he provides the option of healthcare insurance to all his paid staff; he ran a clean, non negative primary campaign stressing his positions on issues; Foster opposes the war in Iraq, champions legitimate, unfettered science and research, and supports stem cell research, just to name a few. http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx To appreciate the scientific side of Dr Bill Foster, follow me below to examine one of the most fascinating, spectacular light-shows our universe can serve up.
Stars that blow themselves to smithereens often produce magnificent sights before, during, and especially after an official supernova explosion. The enigmatic Eta Carinae, below left, is thought to contain a highly unstable star on the precipice of a hypernova. The lacy remains of a supernova observed in 1054 AD is now the Crab Nebula, a tiny, rapidly rotating neutron star lurks noisily inside.
The three schematics below courtesy of graphic artist Karen Wehrstein illustrate the basics of what is thought to happen deep inside a massive, aging star near the end of its life, during a classic kind of Supernova called a Type ll. After burning successively heavier elements, the star eventually begins producing iron at its center. It's a stellar dead end. The iron core grows, robbing the star of energy due to the idiosyncrasies (See comment) of atomic physics, and soon reaches a critical threshold; a massive ball of iron thousands of kilometers in diameter suddenly collapses dramatically, like a soap bubble, into an unimaginably dense remnant a few kilometers wide. Overlying superheated plasma, compressed so much it weighs way more than lead -- quickly falls in to fill the gaping void. When it slams in to the surface of the degenerate core it begans fusing furiously. Short version: Star Go Ka-BOOM!
This does two things: it sets up a huge rebound, sending the outer layers of the star back out, and also releases a vast number of neutrinos .. The gas from the outer layers absorbs these neutrinos, which is like lighting a match in a fireworks factory. The outer layers explode upwards, and several solar masses of doomed star tear outwards at speeds of several thousand kilometers per second.
Under normal conditions, neutrinos are ghostly little particles that overwhelmingly zip through ordinary matter, even a million miles of solid lead, like it was so much hard vacuum. They dwell in an incomprehensible universe seething with subatomic wraiths, not quite pure energy, not entirely solid matter, but a whiff of both. These are not ‘ordinary’ objects. The neutrino represented as a little dot or arrow racing around is an avatar of sorts; a symbolic construct of a hazy particulate property from the surreal world of high energy http://louis-j-sheehan.info/ http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us/physics that our large, clunky macro-minds can latch on to. They’re sleeting through you by the trillions as you read this. No need for alarm though: fortunately for us, they don’t interact with the matter in our body!
But every now and then, one in uncounted zillions will cause a sub-atomic change which can in turn produce a tiny flash of light. So, with a giant tank of a clear substance, shielded from as much radiation as possible, surrounded by sensitive photo detectors, every now and then a lone of neutrino can be confirmed. Since these little guys whip through ordinary matter effortlessly, they’re a potential window deep into high energy places we cannot directly observe, like the fusing core of a star. And since a single light ray can take up to a million years to stagger drunkenly out of a stellar core, while neutrinos simply slip through the outer layers of plasma, neutrinos also uniquely offer current information about the state of affairs in places we can’t otherwise observe in real time.
On February 23, 1987, three separate neutrino detectors recorded a spike lasting just a few seconds. This was a strong indication that somewhere in the universe, something really, really big and no doubt violent beyond imagination had happened.
The next day several astronomers, amateur and professional, reported a small but bright point in a nearby dwarf galaxy called the Large Magellanic Cloud. Within a few hours of that report pretty much every telescope in the southern hemisphere had swung to the anomaly. The source was a star estimated to be twenty times heavier than our sun. Except now it was gone, and in its place was the blazing Supernova 1987A. Right: Several frames taken over the course of a decade by the Hubble Space Telescope, and after the initial supernova faded, show the effects of secondary spasms of invisible gas expelled at extreme velocity smacking into a ring of previously ejected material.
One of the instruments that recorded a spike was the Irving-Michigan-Brookhaven proton decay detector. The futuristic chamber of ultra pure water surrounded by two-thousand photodetectors is shown left (The source of the bubbles is a diver inspecting the equipment). Bill Foster played a significant role in the development of the IMB. When the neutrinos set off alarm bells in 1987, Foster had moved on to Fermilab. But because of his involvement with the IMB detector and the subsequent neutrino detection from SN1987A, Foster and his team shared in the 1989 Rossi Prize in high energy physics.
If anything like SN1987A happened too near our planet, the earth would evaporate faster than a snowflake in a bonfire. And yet we may owe our existence to these violent events. The shock wave from SN 1987A will travel outward, essentially forever. Along the way it will combine with other blast fronts, forming waves of compactions and rarefactions in the medium of thin interstellar gas. Simultaneously it will salt those vast clouds of buoyant hydrogen and helium with heavier substances, volatile gases, ices, and metals. The immense waves will diffract causing nodes, small pockets will condense here and there. Gravity will take hold, and the knots of gas will shrink under their own weight, they will begin to glow with dozens of individual sparks, each lighting up the infant stellar nursery from inside. In the center of each spark, pressure and temperature will grow so high that hydrogen will begin to fuse: this is the birth of stars, this is how our own solar system may have arisen five billion years ago.
Speaking purely for myself, as an interesting side note about SN1987A: That primary ring allows astronomers to calculate the distance between us and SN1987A using simple trigonometry. That distance is about 168,000 light-years, meaning the proginator star blew up about 160,000 years before young earth creationists believe the universe began. In addition, short lived isotopes can be seen decaying in the spectra from SN1987A. That is a direct, empirical observation that radio decay rates in the past were the same as predicted by atomic theory and observed in labs today.
Thus, SN1987A is like a Wrecking Ball of Reality to two basic tenets in Young Earth Creationist apologetics: The age of the universe and the validity of radiometric dating. http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx Doesn't it seem fitting then, in some cosmic way, that the candidate who contributed to our elegant understanding of the universe should prevail over the other fellow, who hails from a party where antiscientific concepts like climate change denial and creationism are badges of honor?
The polling in what should be an easy GOP victory shows Foster in a dead heat with Republican opponent Jim Oberweis. Republicans are intersted in holding the seat (John McCain is reportedly going to hold an Oberweis fundraiser with a goal of 200,000 dollars). So, if that poll is close to accurate, it is a blinking red warning that this campaign needs every vote, every volunteer, and every dollar it can muster to succeed.
Given the obvious difference between these two candidates, it seems a no brainer that the residents of IL-14 would be best served by Oberwies staying in town, and focusing on improving his already scrumptious home-made ice cream. Whereas voters in IL-14 would be far better represented by a Congressman with Bill Foster’s intellect and accomplishments serving their collective interests in Washington, DC.
If Foster manages to pull this off, it will send a powerful message about what may be in store for other 'safe GOP seats' in 2008 -- a progressive message that incidentally embraces science and reason -- well beyond the confines of Illinois' fourteenth district, and into every nook and cranny in this nation. So if I didn't convince you up there, I hope I've provided you some reason to give Bill Foster's qualifications a second look down here.
Was awfully as tempting to make a pun about Oberweis being served there at the end ... I mean to say, If it’s Sunday, it’s Sunday Kos!
It's not an idio whatever of physics.
Fusion reactions release energy up to a point where the nucleus is most energetically stable - the lowest energy configuration. The Iron nucleus is that configuration.
Heavier elements than iron are built in most cases by neutron adsorption, not fusion reactions.
"It's the planet, stupid."
This was a really cool candidate endorsement, DS, and well written for a pop audience. However, the gravitational collapse of the iron core is just too amazing to brush over.

Louis J Sheehan Esquire 301121 photo 51
Bartholomew I, Ecumenical Patriarch of Constantinople, can be regarded as the "pope," or at least the symbol of unity, of Orthodox Christianity. The denomination's 300 million or so adherents make it the second-largest body of Christians in the world, after Roman Catholicism. The 67-year-old Bartholomew also represents one of Christianity's most ancient branches as the latest in a line of 270 archbishops of his city -- modern Istanbul -- that traces itself back to the apostle St. Andrew, brother of St. Peter, in a part of the world where the Christian faith has existed since New Testament times.
In December 2006, Bartholomew, patriarch since 1991, was thrust under the world-wide media spotlight when he celebrated the Orthodox Divine Liturgy with Pope Benedict XVI. The two met in the tiny Church of St. George in the equally tiny patriarchal compound in Istanbul, all that remains of an Eastern Christian civilization on the Bosporus so glistening and powerful that for more than 1,500 years Constantinople called itself the "new Rome." http://louis-j-sheehan.net/
Now Bartholomew has a forthcoming book, in English, "Encountering the Mystery: Perennial Values of the Orthodox Church" (Random House). It purports to be a primer to Orthodoxy, with short chapters on ritual, theology, icons and so forth. What it really is, perhaps inadvertently, is a telling glimpse into the mindset of a church that, venerable and spiritually appealing though it may be, is in a state of crisis. And the book reveals the jarringly secular-sounding ideological positions its leader seemingly feels compelled to take in order to cultivate the sympathy of a Western European political order that is at best indifferent to Christianity.
The Orthodox community, rooted mostly in Russia and Eastern Europe, is in "apparently irreversible demographic decline," as religious historian Philip Jenkins wrote in 2006, thanks to falling birthrates, cultural secularization, turf battles between the various ethnically focused Orthodox churches, and past communist ravages. The historic Christian communities in the Islamic-dominated world -- some Orthodox -- have fared even worse, their numbers reduced as members frantically immigrate to the West under pressure from terrorism, persecution and religious discrimination. The historic fate of Christianity in Islamic-majority lands has been cultural annihilation, whether gradual over the centuries or, as in recent decades, swift. http://louis-j-sheehan.net/page1.aspx
Nowhere does the plight of Christians look so pitiful as in Turkey, nominally secular but 99% Muslim. At the turn of the 20th century, some 500,000 Orthodox Christians, mostly ethnic Greeks, lived in Constantinople, where they constituted half the city's residents, and millions more resided elsewhere in what is now Turkey. Today, Bartholomew has only about 4,000 mostly elderly fellow believers (2,000 in Istanbul) left in Turkey's 71 million-plus population. The quasi-militaristic regime of Kemal Ataturk that supplanted the Ottoman Empire during the 1920s forcibly Westernized the country's institutions but also made Islam an essential component of the Turkish national identity that it relentlessly promoted.
"Kemalist ideology regarded Christianity as Greek and thus foreign," says Greek Orthodox writer Joshua Treviño. The result was a series of official and unofficial ethnic cleansings, population transfers, massacres and pogroms in Turkey, such as the wholesale destruction of Orthodox churches in 1955. The murders of a Catholic priest in 2006 and of an Armenian Christian journalist and three evangelicals, two of whom were Turkish converts, in 2007, together with threats and assaults against other Christian clergy by ultra-nationalists and Islamic militants, indicate that such anti-Christian animus is far from dead. Furthermore, the current government refuses to allow the reopening of Turkey's sole Greek Orthodox seminary, closed in 1971, which means that there have been no replacements for Turkey's aging Orthodox priests and -- since Turkish law requires the patriarch to be a Turkish citizen -- no likely replacement for Bartholomew himself, whose death may well mean the extinction of his 2,000-year-old see. http://louis-j-sheehan.info/page1.aspx
Nonetheless, Bartholomew devotes the bulk of his book to anything but the mortal threat to his own religion in his own country. High on his list of favorite topics, most with only a tangential relationship to Orthodoxy, is the environment. He has won the nickname "the Green Patriarch" for the decade or so he has preached the ecological gospel, largely to liberal secular audiences in the West. "Encountering the Mystery" is in large part a collection of eco-friendly platitudes about global warming ("At stake is not just our ability to live in a sustainable way but our very survival") and globalization, adorned with a bit of theological window-dressing, that today's secular progressives love to read.
Regarding globalization, Bartholomew cannot decide whether global capitalism is bad ("there are losers as well as winners") or good ("We must learn, therefore, both to think and to act in a global manner"). Plus, we must "transcend all racial competition and national rivalry," "promote a peaceful resolution of disagreements about how to live in this world," and yadda, yadda, yadda. Islam comes into play in the book only in terms of another bromide: a call for "interfaith dialogue."
On first reading, this exercise in fiddling while the new Rome burns seems pathetic, presenting a picture of a church leader so intimidated by his country's Islamic majority that he cannot speak up for his dwindling flock even as its members are murdered at his doorstep. Bartholomew's book presents an eerie mirror image of the concerns of aging, culturally exhausted, post-Christian Western Europe, happy to blather on at conferences about carbon emissions and diversity but unwilling to confront its own demographic crisis in the face of youthful, rapidly growing and culturally antagonistic Muslim populations. The suicide of the West meets the homicide of the East.
On the other hand, Bartholomew's "green" crusade across Western Europe may actually represent a shrewd last-ditch effort to secure a visible profile and powerful protectors for his beleaguered church. The patriarch has been an incessant lobbyist for Turkey's admission to the European Union, and his hope has been that the EU will condition Turkey's entry on greater religious freedoms for all faiths. http://louis-j-sheehan.info/
"The EU are secularists," says the Rev. Alexander Karloutsos, an administrator for the Greek Orthodox Archdiocese of America, based in New York. "They won't do anything out of religious reasons, but they will do it out of secular reasons if they can be persuaded that what's best for Europe is to have a Muslim state that's pro-Western in values, such as freedom of religion." The bureaucrats of Brussels may care little about Christianity, but they care deeply about global warming and multiculturalism, and on those issues Bartholomew has carved out common ground.
Orthodox Christianity is not dead yet. Its famous monastery on Mount Athos in Greece has enjoyed new growth recently, and in America some Orthodox churches are drawing converts attracted by the glorious liturgy and ancient traditions. It is unfortunate that Orthodoxy's spiritual leader feels compelled to position the Orthodox with a Western Europe that is, in fact, spiritually dead.
Florida's big push to slash homeowner insurance premiums, a major issue in a state hurt by a sinking real estate market, has turned to bust in the face of stiff opposition from the powerful property-insurance industry.
"It certainly didn't pan out," said Bob Milligan, the state's consumer insurance advocate.
"At best we've seen kind of a reduction in the increases, not really decreases from what they were prior to 2006," Milligan said in an interview.
He was referring to the huge increases many homeowners have seen since eight hurricanes crisscrossed Florida in 2004 and 2005, when insurers paid out about $35 billion in insured losses in the state. http://louis-j-sheehan-esquire.us/page1.aspx
Prodded by Gov. Charlie Crist, who has had several insurers subpoenaed over rate issues after campaigning aggressively last year on a promise to fix the insurance problem, state lawmakers have enacted a sweeping package of property insurance reforms.
Among other measures, they doubled the size of Florida's state hurricane catastrophe fund to $32 billion and authorized state-controlled Citizens Property Insurance Corp. to compete directly with private insurers.
Through the catastrophe fund, lawmakers also agreed to provide state-subsidized reinsurance -- backup coverage for property -- to insurers on the understanding that savings would be passed on to their customers.
Though expected to result in a statewide cut in homeowners' insurance premiums averaging 24 percent, Bob Hunter, insurance director at the Consumer Federation of America, said the new laws were now seen cutting rates only about 12 percent.
"It's the big national companies that are balking," Hunter told Reuters, saying they had failed to pass on reinsurance savings to consumers despite record profits in recent years.
One such company is Allstate Floridian Insurance, a unit of Allstate Corp, the nation's largest publicly traded insurer, which recently filed to raise homeowner rates in Florida by nearly 42 percent.
Allstate Floridian spokesman Adam Shores said the increase, partly prompted by a decision to buy additional reinsurance on the private market, was in line with harsh economic realities and the costs associated with catastrophic risk.
"We fully recognize that this is a difficult time for a lot of Floridians; people are hurting; and they're experiencing a lot of high costs with property insurance, property tax, things of that nature. But we need to be in a position of financial strength to protect customers when a major catastrophe strikes, like we know it will," Shores said.
"There have been a lot of promises that have been made by the political leaders in Tallahassee about where rates would be and what those rates would look like," he added. "The promise that we have made, and the promise that we will continue to stand by, is to be there for our customers when it comes time to pay their claims." http://louis-j-sheehan-esquire.us/
Crist, a Republican, is still pressing for relief in a state saddled with what industry insiders rate as the second- or third-highest priced homeowner's insurance of any state in the country. He appeared to win at least a partial victory last week when State Farm agreed to cut its property insurance rates in Florida by an additional 2 percent, on top of the 7 percent cut it implemented earlier this year.
State Farm, one of three companies hit with subpoenas by officials probing high insurance costs, has also agreed to cooperate with authorities on further investigations into potential collusion between insurers, trade associations and rating organizations aimed at preventing homeowner premiums from going down.
Since more dramatic rate cuts have failed to materialize so far, however, many Floridians say they back a measure proposed by two of the state's Democrats, who recently submitted a bill in Congress calling for the creation of a federal catastrophe fund where states could pool their risks against future storm damage.
"The citizens of Florida are really fed up," said Teri Johnston, who heads a grass-roots organization known as Fair Insurance Rates in Monroe that has pushed for insurance cuts in the Florida Keys.
"They're very frustrated and angry right now," said Johnston, who noted that skyrocketing premiums have been driving residents out of a place once considered a sun-drenched, tropical paradise at a rate of about 17 people a day.
Like other homeowners in southernmost Key West, Johnston said she currently pays more than $1,000 a month to insure her 1,200-square-foot house there.
"It's something that's supported by a number of important insurers," Bob Hartwig, president of the Insurance Information Institute, an industry trade association, said when asked about a federal catastrophe fund.
"I think the issue is getting somewhat more traction and interest in Congress," he added. "As we move along I think we'll hear more about this." http://louis-j-sheehan.org/
Patients with multiple clogged arteries are better off getting bypass surgery than stents, a study found.
The analysis, published in the New England Journal of Medicine, isn't likely to settle the dispute between cardiac surgeons, who perform bypasses, and the interventional cardiologists who implant stents. But it gives further ammunition to those who argue that stents -- metal scaffolds that keep arteries propped open -- are overused.
Both procedures fall under the umbrella of revascularization -- attempts to relieve chest pain by opening up arteries clogged by heart disease. In the most severe cases, revascularization has also been shown to reduce heart attacks and deaths.
The study looked at the newest kind of stents, those coated with drugs to keep arteries open, made by Johnson & Johnson and Boston Scientific Corp. in the U.S. Previous studies saw similar results with older, bare stents.
In stenting, introduced in the 1990s, doctors thread a stent up through a small incision in the leg, widening clogged arteries instead of replacing them. A patient can be back at work the next day. A bypass requires open-heart surgery and has patients laid up for weeks.
As a result, bypass surgeons have been left to treat only the most severe cases of heart disease. The number of bypass surgeries has declined and bottomed out recently at about 300,000 procedures in the U.S. last year, according to Millennium Research Group. That compares to about a million stentings. The average cost of a multivessel bypass surgery and office follow-up visits over two years was put at about $28,000 in one study, versus about $20,000 for multivessel stenting. http://louis1j1sheehan1esquire.us/page1.aspx
But patients who opt for stenting may be paying a price down the road. In this week's study, doctors at the University at Albany looked at patients who received a stent or bypass in New York state in 2003 and 2004, comparing subsequent rates of death and heart attacks. The actual death rates between the competing procedures didn't differ. But after adjusting for risk factors -- bypass patients were sicker to start out -- the study found substantial differences.
After adjustments, New Yorkers with two clogged arteries who received a bypass had a 29% lower death rate over the next 18 months than those who received stents. Three-quarters of such patients had opted for stenting. For the sickest patients -- those with three clogged arteries -- surgery yielded a 20% lower death rate. Two-thirds of those patients received surgery.
Donald Baim, Boston Scientific's chief scientist, said the fact that the differences in death rates arose only after statistical adjustment is cause for skepticism. The company has funded a study that will assign patients randomly to stenting or surgery, eliminating the need for such adjustments. "People are voting with their feet that they would rather have the less-invasive procedure," Dr. Baim said. http://louis1j1sheehan1esquire.us/page1.aspx
You wouldn't expect to learn much about the properties of water by watching a square dance. But think again. Following the caller's lead, the dancers meet, separate, weave, and swing in a perfectly fluid manner.
It turns out that similar coordinated maneuvers—with water molecules taking the places of the dancers—may be responsible for some of water's most puzzling features, an array of recent research findings suggest.
As liquids go, water is a radical nonconformist—differing from other liquids in dozens of ways (see the latest count at www.lsbu.ac.uk/water/anmlies). Most famous among water's peculiarities is its density at low temperatures. While other liquids contract and get denser as they cool toward their freezing points, water stops contracting and starts to expand. That's why ice floats and frozen pipes burst. http://louis1j1sheehan1esquire.us/
Confining water molecules in nanometer-size pores has provided new evidence that, in addition to its many other oddities, H2O may exist in two distinct liquid phases at ultralow temperatures. Nicolle Rager Fuller
Water gets even weirder at colder temperatures, where it can exist as a liquid in a supercooled state well below its ordinary freezing point. Recent evidence suggests that supercooled water splits its personality into two distinct phases—another oddity unseen in other liquids. And last year, water surprised scientists yet again, when they found that at –63 degrees Celsius, supercooled water's weird behavior returns to "normal."
That discovery, scientists say, may help explain some aspects of water's peculiar personality, such as its ability to transition from gas to liquid to solid and back to liquid again. Findings from related experiments have important implications for understanding how water interacts with biological molecules, such as proteins, and may lead to better ways of freezing and storing biological tissues such as sperm and human oocytes. http://louis-j-sheehan.org/page1.aspx
Water's ability to exist in a liquid state well below its freezing point has been studied for centuries. What's new, scientists say, is growing evidence about what happens to water at superlow temperatures. Under these extraordinary conditions, there is not just one kind of water, but two.
This two-phase phenomenon was first predicted in 1992 by physicist H. Eugene Stanley of Boston University and his graduate student Peter Poole, now at St. Francis Xavier University in Antigonish, Nova Scotia. Using computer simulations to study the behavior of liquid water at very low temperatures, the scientists suggested that water could exist as either a high-density liquid or as a low-density liquid. http://louis-j-sheehan.com/
Stanley and Poole also proposed that the dividing line between these two liquid forms might end in a "critical point," where the two liquids would become indistinguishable, changing from one form to the other.
In a series of experiments in recent years, scientists have begun to close in on this critical point. These advances offer a glimpse of possible explanations for water's unusual behaviors, and suggest that Stanley and Poole may have been on to something.
Some of water's odd properties have traditionally been explained as consequences of the hydrogen bonds that form between water molecules (and sometimes other molecules). Each V-shaped molecule of water contains one oxygen atom centered between two hydrogen atoms. The chemical bonds holding the molecule together create a slightly negative charge on the oxygen atom and a small positive charge on each of the hydrogen atoms. http://louis-j-sheehan.com/page1.aspx
FORCES OF ATTRACTION. Water molecules are held together in a flexible, but stable network of hydrogen bonds. The bonds, though weak, help keep water liquid over a wider temperature range than one would expect for molecules of its size. Nicolle Rager Fuller
These unequal charges make water molecules extremely "sociable"—eager to bond with each other. Because hydrogen bonds are much weaker than normal chemical bonds, the water molecules move about freely, binding briefly with adjacent molecules before moving on to others. Stanley likens this fast-paced network to a square dance taking place in a large dance hall.
"In square dancing, you're always releasing one partner and grabbing another, and that is a hydrogen bond network, exactly," he says.
In the case of water, the square dance occurs among molecules that have four arms, instead of two. That's because each water molecule has the potential to form four hydrogen bonds. The result is a network of tetrahedrons, or pyramids with a triangular base.
This tetrahedral arrangement creates a peculiar tension, permitting structural changes in response to different temperatures and pressures. In liquid form, the tetrahedral structures allow unrestrained hydrogen bonding to occur as numerous molecules pack into and around the tetrahedron. (Imagine a swift square dance with dancers moving in and out of the center of the square and circling around it as well.) The result is a dense, fluid structure, such as that of everyday tap water.
As water approaches its freezing point (0°C), however, the tetrahedral structure becomes more open and begins to expand. Ordinary water reaches its maximum density at 4°C. As water continues to cool, falling to its freezing point and below, it continues to expand.
Here, the tetrahedral arrangement is more rigidly enforced, with molecules spaced an "arm's length" apart. The arrangement creates a more spacious, open structure, and water becomes lighter. If ice weren't lighter than cold water, ponds and lakes would freeze from the bottom, rather than form a floating layer of surface ice, and water would cease flowing in the dead of winter. Water's weirdness therefore allows fish to swim in the water beneath the ice and plants to survive the winter cold.
At temperatures below the freezing point, ice crystals form around defects, such as cracks or dust particles. By using extremely clean water samples—free from any such defects—scientists have found ways to defy freezing and obtain supercooled liquid-water that remains liquid below 0°C.
This procedure works only to a certain point. At extremely cold temperatures, (–38°C and lower), it is nearly impossible to keep water from freezing. But under certain conditions, such as the ultrahigh pressures found deep undersea, water can remain liquid even at such low temperatures. Scientists have been unable to make water that cold in the laboratory, though, and so what Stanley calls a "no man's land" of conditions had been explored only in computer simulations.
But now, using a clever technique to confine water samples in nanoscopic pores, scientists are beginning to explore the structure and properties of deeply supercooled water.
As even a square-dancing novice knows, you can't hold a hoedown in a cramped, narrow hallway. Water's hydrogen-bonding network is a fast-moving, gregarious one. Cramming water molecules into a tiny space, with a diameter less than five water molecules wide, brings the molecular square dance to a standstill.
"If a room were very, very narrow, it would be hard to have a normal square dance because a lot of people would be up against the wall and there would be no partner to grab on to," Stanley says. "In a similar fashion, water molecules that are confined against a wall have only two or three arms, and the whole hydrogen-bond network is disrupted." http://louis-j-sheehan.com/page1.aspx Because the hydrogen-bond network brings stability to water, the breakdown of this network changes water's properties, allowing it to remain liquid at a much lower temperature, he says.
Scientists began exploring ways to nanoconfine water molecules more than a decade ago, using a spongelike material that had holes of different sizes. http://louis-j-sheehan.biz/page1.aspx While the experiments showed that nanoconfinement could be used to cool water well below its usual freezing temperature, the results were often hard to interpret because water in the larger holes would freeze, causing crystallization throughout the material. http://louis2j2sheehan.us/Blog/Blogger.aspx
In 2005, Sow-Hsin Chen of the Massachusetts Institute of Technology and his colleagues found a way to get around this problem, using a new material called MCM-41. Chung-Yuan Mou of National Taiwan University of Taipei had created MCM-41 by refining the fabrication of silica-nanotube assemblies. The material resembles a microscopic beehive with a hexagonal array of holes, all uniformly sized, just a few nanometers wide.
Curious to see how confined water might respond in MCM-41, Chen filled the hexagonal arrays with water. He then cooled the water to –73°C and bombarded the arrangement with neutrons. The microscopic cells of MCM-41 not only prevented ice crystals from forming but also allowed the scientists to probe water's molecular structure. http://louis2j2sheehan.us/page.aspx
Building on this work, Chen and colleagues conducted a series of experiments to see how water's properties change as temperature drops at ordinary pressures.
In 2006, Chen showed that, when cooled below 225 kelvins (or –48°C), water's hydrogen-bonding structure undergoes a phase transition, changing from a disordered, fluid state to a more ordered, rigid state. Furthermore, this line of transition between a high-density liquid and low-density liquid, called the Widom line, occurred in a continuous fashion, as predicted by Stanley and Poole in 1992. This transition, called a fragile-to-strong dynamic crossover, helped explain why, at superlow temperatures, proteins and other biological molecules exist in a glassy state, losing all flexibility and biological function.
"This dynamical transition of protein at 225 K is triggered by its association with the hydration water, which shows a similar dynamic transition at that temperature," Chen says. http://louis-j-sheehan.de/
In addition, the study showed that water's phase change at 225 K—moving from a disordered state to a more ordered state—violates a well-known formula called the Stokes-Einstein relation. This formula, based on a picture of a disordered, fluid state, ties together liquid properties such as diffusion, viscosity, and temperature, and generally works for normal- and high-temperature liquids.
Because this formula breaks down in subzero conditions, the experiment suggests that supercooled water may be a mix of two liquid phases, rather than a single liquid. Chen's study, published in the Proceedings of the National Academy of Sciences (PNAS), provided the first experimental evidence of such "liquid polymorphism" and received the journal's 2006 prize for best paper. http://louis-j-sheehan.us/
Last year, Chen and his colleagues surprised the scientific community, and themselves, when they discovered that under supercold conditions, liquid water again begins to expand, returning to normal behavior. Using a neutron-scattering method and analysis to measure the density of subzero liquid water, they showed that water reaches a minimum density at 210 K, or –63°C. http://louis-j-sheehan.biz
In doing the experiments, the scientists used heavy water, or D2O, because of its neutron-scattering properties. They then repeated the experiments using regular water and two light-scattering techniques and came up with the same results. The findings were reported last June in PNAS.
Though this kind of behavior had been predicted in computer simulations, it had never been observed. The findings add to the long list of experimental anomalies associated with supercooled water, and provide the strongest experimental evidence yet for a second "critical point" in liquid water, Chen says. http://louis2j2sheehan.us/page.aspx
A critical point defines the set of pressures and temperatures at which a liquid changes from one form to the other. "It would be hard to explain a density minimum unless there was a second critical point," he says.
Water already has one well-known critical point at 647 K, or 374°C, where, under ordinary pressures, the liquid and gas phases become identical.
MULTIPLE PERSONALITIES. Water's many forms, or phases, change with shifts in temperature and pressure. Below –38°C, at high enough pressures (a region researchers call "no man's land"), water may remain liquid. The precise locations of the phase boundaries are uncertain, but those shown here are supported by computer simulations.
"As water approaches this critical point, the difference between water and steam grows increasingly smaller," Stanley explains. "At the critical point, there is nothing distinguishing water from steam, there is just one, homogeneous fluid."
More important, he says, a critical point serves as a "tipping point," where water can exist in either of two states, and minor fluctuations can tip the balance in one direction or the other.
The hypersensitivity created by a critical point can have far-reaching effects upon a system, says Stanley. In predicting a critical point in supercooled water, he and Poole theorized that water's crazy low-temperature behavior might account for some of its unusual properties even at ordinary temperatures. http://louis2j2sheehan.us/page1.aspx
That's because changes at a critical point don't occur abruptly, Stanley says. The huge changes seen near the water-gas peak, for example, are often, if not always, foreshadowed by fluctuations over a large range of temperatures and pressures.
"It's like looking at the highest peak on a mountain range," Stanley says, gesturing toward a picture of Mount Everest in his office. "The critical point, or summit, doesn't rise out of nowhere, but rises in a gradual manner and distorts the terrain all around it."
That means that a critical point at –63°C might account for water's bizarre behavior at much higher temperatures, such as its ability to expand as it cools.
Though findings from recent studies point to the predicted second critical point, it is still too soon to know whether such a point exists for sure. Further evidence is needed. http://louis1j1sheehan.us/
This year, Chen and his group will seek some of that evidence by performing another, more far-reaching set of experiments on supercooled water in MCM-41. Using a specially designed pressure cell for low temperatures, the scientists will analyze changes in liquid water as it moves from its maximum density point at 4°C to its minimum density at –63°C and beyond under various pressures. By studying how density changes with temperature and pressure, the researchers hope to locate the liquid-liquid critical point precisely.
"The critical point is at a high pressure, and no one knows exactly what it is, but we believe it's probably above 1,000 atmospheres," Stanley says.
Other scientists are raising questions about the extent to which supercooled water in confined volumes, no matter what the pressure, actually behaves like cold, bulk water.
"When you put water into confinement, it changes the way in which water molecules are arranged with respect to each other," says C. Austen Angell, a chemist at Arizona State University in Tempe, who studies liquid phases in supercooled water. "The question is, how much does it change it?" http://louis1j1sheehan.us/
Angell notes that despite recent progress, much remains uncertain and many of the explanations are built on simulations that can give different results, depending on the model and tools used in the study.
"There are other possibilities, related to the second critical point scenario, in which the low-pressure supercooling of uncrystallized bulk water is terminated by a first-order [sharp] transition to a second 'low-density' liquid phase," he says. Angell's take on supercooled water will appear in an upcoming issue of Science.
Confirming the predicted second critical point could have an impact beyond the study of water's molecular mysteries for their own sake.
Biologists, for example, are looking at how this transition in liquid states, and the accompanying rigidity it brings, affects living structures such as proteins and DNA. http://louis1j1sheehan.us/
Other practical benefits could flow from the new water knowledge. For example, scientists at Cornell University have found that high-pressure cooling of protein crystals causes them to diffract better than they would if flash frozen, and has allowed scientists to improve methods for crystallizing and studying proteins and other biological tissues.
The scientists are now pursuing ways to use high-pressure techniques to improve methods for freezing sperm and human oocytes. The studies may lead to better ways of freezing and storing sperm for livestock production and allow women to freeze their eggs and use them at a later time to conceive a child.
The studies may also help explain some more ordinary, everyday occurrences related to water's mysterious behavior. Chen recalls hiking in New Hampshire's White Mountains, a site known for its frigid temperatures and long months of ice, and noticing that the trees stopped abruptly at 4,400 feet, nearly 2,000 feet below the summit of Mount Washington. Soon after he published his findings on a minimum density, he received a phone call from a Canadian biologist who was interested in the work.
"It turns out that this tree line stops where the windchill temperatures reach 220 degrees K," Chen says, noting that this is the temperature at which water's hydrogen-bonding structure undergoes a phase transition, changing from a fluid state to a more rigid state. http://louis1j1sheehan.us/
At this point water becomes very, very slow, and no longer supports biological functions. Or, to put it another way, the square dance of water comes to an end.
Lightning does strike twice and more than twice in the same place, it is demonstrated by the photograph appearing on the front cover of this week's Science News Letter. Eleven separate strokes make up what appears to the eye as a single lightning flash.
The strokes, which come so fast that the human eye cannot distinguish them, were photographed by General Electric Co. scientists. The Empire State Building in New York City is the target.
The flash as the human eye sees it (main flash in center) was caught by one camera lens, while another one, rapidly rotating, caught the 11 separate strokes. The first one is the streak at the right, the last one is at left. The flash took 0.36 second altogether.

The Earth's salty oceans are some 500 million to 700 million years old, almost double the accepted previous estimates, Drs. A.C. Spencer and K.J. Murata, of the U.S. Geological Survey, have concluded after an intensive study of oceanic chemistry. http://louis1j1sheehan.us/
Before the turn of the century, geologists determined the age of the oceans by dividing the amount of salt in them by the amount added each year. This was based on the idea that all the salt brought to the oceans by rivers stayed there. Such an early determination of age, after hundreds of surveys and analyses, was about 100 million years. Later research brought the age to 350 million years, but such figures were found to be too small. Dinosaurs are now known to have existed about 100 million years ago, and oceans obviously existed long before that.
Studying the action of clay on salt water, Drs. Spencer and Murata in the recent work have found that some of the salt carried to the oceans is removed by clays, and deposited on the sea floors as a compound that does not easily dissolve. Correcting the old figures for this salt removal gives them the new age figure of 500 million to 700 million years. http://louis1j1sheehan.us/
The geologists who measure the Earth's age by the products of the decay of radioactive elements are expected to say the new ocean age estimates are too small. They pronounce the Earth at least 2 billion years old. While the Earth in its earlier stages may have been oceanless, there is in the radioactive age figures plenty of room for even more ancient oceans.

The flaming younger generation stands condemned as the greatest group of mass murderers in America. The weapon is the automobile.
Although including more highly skilled automobile drivers than any other age group, 100,000 drivers between 16 and 20 years of age kill nearly twice as many on the road as the average 100,000 drivers.
Accident rates for those below 25 years of age are so high that bringing down that age group's accident rate to the general level would save nearly 8,000 of the nearly 40,000 killed each year on the American highway and street.
These challenging figures were presented to the American Association for the Advancement of Science by Dr. Harry M. Johnson, research associate for the Highway Research Board, Washington. Young men between 19 and 21 years of age are apparently the worst menaces on the highway, Dr. Johnson declared, pointing to a chart which indicated plainly that young men just approaching their majority are responsible for many more accidents per 100,000 drivers than any other group. http://louis1j1sheehan.us/
FOR TODAY'S CIVILIZED WORLD, WITH ITS DOT-coms, sitcoms, ATMs, and ATVs, the first 3.5 billion years of life on Earth are a bit of an embarrassment. It was only a few hundred million years ago that trilobites prowled the seas. More primitive life subscribed to two or three basic lifestyles: algal mat, spineless worm, or bacterial blob. Before that, in the Archean Eon more than 2.5 billion years ago--well, that kind of life is what Lysol is for. Scientists, of course, see it differently. "Almost everything of any biological importance happened back in the Archean," says Andrew Knoll of Harvard University, author of the upcoming book Life on a Young Planet. Soon after the infant Earth cooled down, he says, primeval microbes began processing essential elements--carbon, sulfur, and nitrogen, among others--that allowed for the eventual emergence of higher life-forms, including us. To this day, says Knoll, bacteria still do the biosphere's heavy lifting. "We just sit back and live off the fruits of their labors." Folks like Knoll would like to know whom to thank for those first trophic cycles. But in the quest to identify Earth's earliest life, geology can look a lot like biology. It's not always easy to tell the dead organisms from the dead ends. One of the few things experts all agree on is where to conduct the search: in the three far-flung provinces that host the world's most ancient sedimentary rocks. Deposits in Australia, Greenland, and South Africa offer a cryptic view of the earth's surface as it was between 3.2 billion and 3.8 billion years ago. The deposits are made up of layers of accumulated particles that were later buried, heated, and compressed. Rounded pebbles and smoothed sand grains in the sediments indicate that they were seabeds, so any life they record would be marine. http://louis-j-sheehan.org/ http://louis1j1sheehan1esquire.us/page1.aspx
The oldest fossil of that life comes from a remote desert site in Western Australia called North Pole. The rocks there bear the marks of stromatolites--sizable mounds of mud and minerals trapped or precipitated by microbial colonies living in shallow ocean water. Modern stromatolites grow knee-high in Australia and the Bahamas, and the organisms that build them leave distinctive patterns in the mud pedestal that can't be duplicated by mere geologic manipulation. At North Pole, those patterns appear in rocks that are almost 3.5 billion years old. The sediment layers in the North Pole fossils are much finer than those in modern stromatolites, suggesting that much smaller life-forms inhabited them. Even so, there's evidence of a food chain of sorts. The principal architects of stromatolites are photosynthetic. They get their energy directly from sunlight instead of feeding off other creatures. But geochemists found the chemical signature of a microbe that was feasting on dead organic matter, a scavenger of sorts. "We had quite sophisticated ecological communities back then, even if they were just tiny little microbes," says astrobiologist Roger Buick of the University of Washington, who discovered the North Pole stromatolites. Unfortunately, the vestiges of microbial communities are far more conspicuous than the remains of their individual members. Lacking bones, shells, teeth, and other hard parts, the first Earthlings didn't fossilize well. In the oldest rocks, chemical leftovers may be the only evidence of animation. So it happens that the earliest evidence of life is not a lithic imprint but a skewed ratio of carbon isotopes in a chunk of rock from southwest Greenland. Microscopic globules of graphite in the rock, documented in 1999 by geologist Minik Rosing at the University of Copenhagen, are unusually low in a heavy carbon isotope that gets excluded when inorganic carbon is converted into living material. Rosing thinks the C-13-poor graphite globules might have come from free-living planktonlike organisms that fell to the seafloor when they died. Their remains, he says, are at least 3.7 billion years old. In 1996 geochemist Stephen Mojzsis, now at the University of Colorado at Boulder, trumped Rosing's find in a report of heavy-isotope depletion in graphite grains from the Isua formation in Greenland and another site on the Greenland island of Akilia. Mojzsis says the grains are 3.85 billion years old--the oldest yet. But his interpretations of both the biological markers and the rock itself have been put through the wringer. One of Mojzsis's former coauthors, geochemist Gustaf Arrhenius of the Scripps Institution of Oceanography, showed how the Isua carbon-isotopic ratio could arise by geologic activity alone, if certain iron minerals in the rock were melted and pressed together over time. He and other investigators also think that the putative sedimentary rocks are actually igneous formations that have been severely transformed by heat. http://louis-j-sheehan.org/ http://louis1j1sheehan1esquire.us/page1.aspx
Thus, rocks of advanced vintage seem to confound even the most basic geologic distinction: igneous, metamorphic, or sedimentary? "These rocks have been buried and cooked at least three times," says Buick. "They've been severely squashed and strained and tied in knots at least three times too. Then they sat around for at least a billion years and got polished by glaciers. These are not ordinary rocks." The ambiguity of chemical evidence leaves geologists hungry for a well-defined, and ideally photogenic, fossil or two. In the early 1990s they thought their hopes had been answered when paleobiologist William Schopf of the University of California at Los Angeles described microscopic structures embedded in a Western Australia formation almost 3.5 billion years old. In his report, dark, slender silhouettes appear in translucent sections of thinly sliced quartz. Schopf says the silhouettes are a complex carbon polymer made by chains of bacteria that may have been anchored to the seafloor. After examining hundreds of present-day microbes, he named 11 possible species in his collection and gave the back story in a 1999 book called Cradle of Life. His menagerie made the Guinness Book of World Records, as the Earth's oldest fossils. "I found a whole bunch of different things," says Schopf. "The question was, what were they?" Schopf decided that at least half could be cyanobacteria, or blue-green algae, the first organisms in the evolutionary record to produce oxygen. That challenges orthodox thinking about conditions on the young Earth, which would not have had a significant oxygen atmosphere for at least another billion years. When geologist Martin Brasier of the University of Oxford had a look at the structures, he decided Schopf was wrong, wrong, and wrong again. The tubes are too branched to come from bacteria, he says. The rock is an extrusion from a hydrothermal vent, not seafloor sediment. And the silhouettes are inorganic carbon injected by the vent and molded into suggestive shapes by the growth of mineral crystals. "Ancient filamentous structures should not be accepted as being of biological origin until all possibilities of their nonbiological origin have been exhausted," Brasier and his coauthors wrote in a report last year. http://louis-j-sheehan.org/ http://louis1j1sheehan1esquire.us/page1.aspx
The hubbub over Schopf's fossils has humbled disciples of early life. "People have become more critical about what they'll accept as evidence of biology," says Knoll. And, as demonstrated by the recent retraction of evidence for life in a Mars meteorite, the stakes are astronomical. Once biologists know where and how life emerged, astrobiologists will be better prepared to look for it elsewhere in the solar system. If life on Earth was a freak accident born of unique and peculiar conditions, it's probably rare elsewhere. But, says Buick, "if life can arise quickly and easily, given the right environment, there might be quite a bit of it out there." Some of the earliest signs of life are found in ancient rock layers called banded iron formations. The iron was released by underwater volcanoes and precipitated from ocean water more than 2 billion years ago. Today the rock formations supply about 95 percent of the iron used to make steel.
Justine Henin's 32-match winning streak may have been ended by Maria Sharapova in the Australian Open quarterfinals this week, but another female tennis champion hopes to continue an even more impressive run in the tournament. Esther Vergeer of the Netherlands, the defending women's wheelchair singles champion, is pursuing her sixth Australian Open title and looking to solidify her claim as perhaps the most dominant competitor in all of sports. http://louis-j-sheehan.org/ http://louis1j1sheehan1esquire.us/page1.aspx
Entering this year's Australian Open, Ms. Vergeer had won 303 consecutive matches. Her last loss came to Daniela Di Toro of Australia in the quarterfinals of the Sydney Invitational in January 2003. Before that, Ms. Vergeer had won 80 straight matches, so since May 2001, her record is 383 wins to one loss.
Wheelchair tennis is played by the same rules as regular tennis except that wheelchair players can hit the ball on the second bounce. It has become a world-wide presence, with the Australian Open, French Open, and U.S. Open including draws for wheelchair players. There are also such premier wheelchair-only events as the Japan Open, British Open and NEC Wheelchair Masters, plus the quadrennial Paralympic Games. Ms. Vergeer played 99 singles and doubles matches last year (losing once in doubles), a schedule more demanding than the ones many Association of Tennis Professionals and World Tennis Association players pursue.
Dutch wheelchair tennis champ Esther Vergeer's current 303-match winning streak is among the longest in all of sports, dwarfing classic streaks like Edwin Moses' hurdles record and UCLA's NCAA basketball streak. Only Pakistani squash champion Jahangir Khan has put together a longer skein of wins. PLAYER SPORT STREAK Jahangir Khan squash 555 matches Esther Vergeer wheelchair tennis 303 matches Edwin Moses track and field 122 races UCLA Bruins basketball 88 games Martina Navratilova tennis 74 matches Rocky Marciano heavyweight boxing 49 fights Oklahoma Sooners college football 47 games
To put Ms. Vergeer's winning streak in perspective, add the four longest women's winning streaks of the Open Era (74- and 58-match streaks by Martina Navratilova; 66 by Steffi Graf; and 57 by Margaret Court) and the total still falls short of Ms. Vergeer's streak by the length of the longest men's Open era streak (46 matches by Guillermo Vilas in 1977).
The rest of her resume is as impressive. She's won 21 Super Series singles titles (the wheelchair equivalent of the Grand Slams) dating back to 2000, a total that dwarfs Roger Federer's career total of 12. The International Tennis Federation has crowned her world champion in her event eight consecutive years, topping Pete Sampras's six-year mid-1990s run and Mr. Federer's still-active four-year streak.
And while Ms. Vergeer has used a wheelchair since a childhood operation to relieve a hemorrhage left her legs unable to move, the source of her dominance would be familiar to any tennis fan. Her movement around the court is unparalleled, and once she gets to the ball, she hits with pace and spin on both her one-handed backhand and her especially effective forehand.
But one way in which Ms. Vergeer can't compete with her counterparts on the ATP and WTA tours is in earnings. The prize money for the entire Australian Open wheelchair event, including men's and women's singles and doubles events, is $47,500, about the same as one player's paycheck for losing in the third round of the men's or women's singles draw.
While Ms. Vergeer's streak is one of sports history's most impressive (see chart), at least one milestone looms in the distance. Pakistani squash champion Jahangir Kahn won 555 straight matches from 1981 to 1986. At age 26, Ms. Vergeer should keep collecting major titles -- but there are signs that her competitors may be closing the gap. From August 2004 to October 2006, she didn't lose a set, a streak of 129 singles matches, but last year she was forced to three sets on three occasions. So as players like Maria Sharapova struggle for another major title in Melbourne, remember that on an outside court, another great champion is aiming not just at victory, but continued perfection as well.

Biologist Craig Venter and his team replicated a bacterium's genetic structure entirely from laboratory chemicals, moving one step closer to creating the world's first living artificial organism.
The scientists assembled the synthetic genome by stringing together chemicals that are the building blocks of DNA. The synthetic genome was constructed so it included all the genes that would be found in a naturally occurring bacterium.
The research was published in the online version of the journal Science by a team of scientists from the J. Craig Venter Institute in Rockville, Md. The authors include Hamilton Smith, who won the Nobel Prize for Medicine in 1978.
"It's the second significant step of a three-step process to create a synthetic organism," said Dr. Venter, in a conference call with reporters. The final step could prove far trickier, though Dr. Venter defied his critics and deciphered the human genome with startling speed about eight years ago.
The larger quest is to make artificial life forms with a minimum set of genes necessary for life. It is hoped that such organisms could one day be engineered to perform commercial tasks, such as absorbing carbon dioxide from the air or churning out biofuels.
The scientific challenge of creating synthetic life isn't trivial, nor are the ethical and legal concerns. There is little government oversight, and researchers involved in such experiments regulate themselves. Detractors worry that the lack of safeguards increases the risks that a potentially dangerous man-made organism might run amok. (In creating the artificial genome of Mycoplasma, Dr. Venter's team disrupted the genes that would enable it to infect other organisms.)
Nonetheless, the science is pushing forward at a rapid pace. In June, a Venter-led team published details of an experiment in which it inserted the DNA of one species of bacteria into the cells of another bacteria species. That process almost magically "booted up" the genome of the donor bacteria, sparking it to life.
The team hopes to use a similar trick to boot up the artificially created genome, to create a man-made living organism. But, Dr. Venter said, "there are multiple barriers" to achieving that goal.
Dr. Venter now believes that the challenge of creating a synthetic organism is within his grasp. "I'll be...disappointed if we can't do it in 2008," he said. http://louis-j-sheehan.org/ http://louis1j1sheehan1esquire.us/page1.aspx In Rare Middle-Class Tomb Found From Ancient Egypt National Geographic reports on the discovery of an Egyptian tomb that was never ransacked by robbers. Neferinpu, the priest and administrator who was buried in the 2 X 4 meter tomb was rich, but as is often true today, his wealth was not enough to make him upper class. His mummified body has badly decomposed because it's from before Egyptian preservation methods had been perfected. By his side were 4 canopic jars, 10 sealed beer jars, among other ceremonial items, and a 2-meter walking stick with a gold end.
Neferinpu was from the Old Kingdom, 5th Dynasty. Another recently discovered tomb, from the 6th dynasty contained the remains of a dentist (see Tomb Robbers Find Egyptian Dentists' Tombs). That tomb had been robbed in antiquity. The National Geographic article says robbers knew it was worth robbing because while in the 5th Dynasty the king was still in control of the burials, by the following dynasty, the central control had weakened and individual officials had more say in their own burials and so could make them more lavish.
The most famous Roman road is the Appian Way (Via Appia) leading from the forum Romanum in Rome to the southeastern coast of Italy, at Brundisium. Originally it only reached as far as Capua, in Campania, when it was built by the censor Appius Claudius (later, known as Ap. Claudius Caecus 'blind'), in 312 B.C., to help with the battles Rome was fighting in the Italic peninsula.
The road was made by laying small stones on a level dirt road and covering them with a flat layer of interlocking stones. http://louis-j-sheehan.org/ http://louis1j1sheehan1esquire.us/page1.aspx
The Appian Way was the site of Clodius Pulcher's murder. Clodius Pulcher was an originally patrician (Claudian) descendant of Appius Claudius who had joined the plebeian (Clodian) section of the family. It was also along the Appian Way that the bodies of the rebellious slaves from the revolt of Spartacus were crucified. Christian legend holds that Peter had a vision of Christ along the Appian Way.
Last year, on the eve of the biggest season of his career, Mr. Gonzalez embarked on a diet resolution that smacked head-on with gridiron gospel as old as the leather helmet. He decided to try going vegan.
Living solely on plant food, a combination of nuts, fruits, vegetables, grains and the like, has long been the fringe diet of young rebels and aging nonconformists. Even the government recommends regular helpings of meat, fish and dairy. Vegans of late have gotten more hip with such best sellers as the brash "Skinny Bitch," and its more scholarly cousin, "The China Study." Both books argue vegans can live longer.
But could an all-star National Football League player, all 6-foot, 5-inches and 247 pounds of him, live on a vegan diet and still excel in one of the most punishing jobs in sports? http://louis-j-sheehan.biz/ http://louis-j-sheehan.us/Blog/blog.aspx http://louis-j-sheehan.us/
For Mr. Gonzalez, the stakes were high. He'd just signed a five-year contract, making him the game's highest-paid tight-end. Entering the 2007 season, his 11th in the NFL, he had a shot at breaking all-time NFL records for career receptions and touchdowns at his position. To do that, he needed top performances in every game. Mr. Gonzalez knew he was out on a limb. "I was like, 'I'm going to look like a fool if this doesn't work out,'" he says.
Mr. Gonzalez joined a handful of elite athletes who have put the vegan diet to the test, either for their health or because they oppose using animals as food. But he was the first pro-football superstar to try. And the first to fail. Kansas City Chief Tight End Tony Gonzalez shows us how to make high protein vegan shakes that actually taste good. (Jan. 24)
There's no evidence a vegan diet can improve an athlete's performance, says David Nieman, a professor of health and exercise at Appalachian State University. His 1988 study of vegetarian runners found they ran as well as their meat-eating rivals but no better. Although the vegetarian athletes in his study also ate eggs and dairy foods, he says, "there is scientific evidence that veganism, when done right, won't hurt performance." But, he adds, there is only anecdotal evidence that it can help.
Professional athletes, especially NFL players, need thousands of calories a day. Many enjoy a high-protein, high-fat smorgasbord of steaks, chops, burgers, pizza, ice cream and beer. Mr. Gonzalez's tight-end job requires him to push around monstrously sized opponents. Occasionally, he gets to catch a pass. Mr. Gonzalez is famous for combining the brute power of an offensive lineman with the acrobatic skills of a nimble receiver. "My biggest thing is strength," he says. "If you lose that strength you get your butt kicked."
Experts say athletes in training need as much as twice the protein of an average person to rebuild muscle. Their bodies also require a big dose of minerals and vitamins, as well as the amino acids, iron and creatine packed into fish, meat and dairy foods. It's fine to be a vegan, says sports nutritionist and dietician Nancy Clark, if you're willing to work at it. "It's harder to get calcium, harder to get protein, harder to get Vitamin D, harder to get iron," she says. "You have to be committed."
"Skinny Bitch" co-author Kim Barnouin is working on another book called "Skinny Bastard." "We want men to know that you're not going to be some scrawny little wimp if you follow this diet," she says. The book trashes meat, milk, eggs, cheese and sodas, saying men and women feel better and look better without them. "The more athletes who come forward and say, 'I'm doing this for my health,' the better," she says. http://louis-j-sheehan.biz/ http://louis-j-sheehan.us/Blog/blog.aspx http://louis-j-sheehan.us/
Mr. Gonzalez had never heard of the vegan diet when he boarded a flight from New York to Los Angeles last spring, about a month before preseason training. His seatmate turned down most of the food offered in first class, and Mr. Gonzalez finally asked why. The man told Mr. Gonzalez about "The China Study," a 2006 book by Cornell professor and nutrition researcher T. Colin Campbell that claims people who eat mostly plants have fewer deadly diseases than those who eat mostly animals. The evidence was drawn from diet surveys and blood samples of 6,500 men and women from across China.
Mac Danzig took a diet risk four years ago. The 28-year-old mixed martial-arts fighter had long wanted to spare animals by going vegan. But he was afraid his trainers were right: that he'd lose to stronger opponents. Last month, on a diet of brown-rice protein, beans, soy, nuts and vegetables, Mr. Danzig defeated the last of his challengers in Spike TV's "The Ultimate Fighter." Kim Barnouin, co-author of the vegan best-seller "Skinny Bitch," says she loves the "Ultimate Fighter" show and cheered Mr. Danzig's win. When fight fans learned Mr. Danzig was a vegan, some said they didn't think he'd have the strength, or the stomach, to conquer the ultra-violent sport, which combines kick-boxing and wrestling. "It's about animal rights," Mr. Danzig says, "not human rights."
Mr. Gonzalez was intrigued. Earlier in the year, a bout with Bell's Palsy, a temporary facial paralysis, had focused his attention on health. He bought the book, and after reading the first 40 pages, he says, was convinced animal foods led to chronic illness. He was an unlikely convert. Mr. Gonzalez, who grew up in Southern California, says cheeseburgers were his favorite food. But he quit them, substituting fruits, nuts and vegetables. At restaurants, he ordered pasta with tomato sauce. http://louis-j-sheehan.biz/ http://louis-j-sheehan.us/Blog/blog.aspx http://louis-j-sheehan.us/
Three weeks later, he walked into the weight room at the Chiefs' training facility and got a shock. The 100-pound dumbbells he used to easily throw around felt like lead weights. "I was scared out of my mind," he says. Standing on the scale, he learned he'd lost 10 pounds.
Mr. Gonzalez considered scrapping the diet altogether and returning to the Chiefs' standard gut-busting menu. First, though, he called Mr. Campbell, who put him in touch with Jon Hinds, himself a vegan and the former strength coach for the Los Angeles Clippers basketball team. Mr. Hinds suggested plant foods with more protein.
Trainers for the Atlanta Hawks worried when shooting guard Salim Stoudamire decided to eat vegan at the end of the National Basketball Association season in 2006. Although the diet left him craving chicken, Mr. Stoudamire says, his biggest challenge was convincing coaches and teammates he could still perform on the court. Team managers forced Mr. Stoudamire onto a scale each morning of preseason training and wrote down his weight. After holding steady at 181 pounds, the bosses got off his back. Mr. Stoudamire says he felt better, and that his performance this season improved. So far, none of his teammates have joined him. "They all look at me like I'm crazy," he says.
The Chiefs' team nutritionist, Mitzi Dulan, a former vegetarian athlete, did not believe that was enough. With the team's prospects and Mr. Gonzalez's legacy at stake, she persuaded the tight-end to incorporate small amounts of meat into his plant diet. Just no beef, pork or shellfish, he said; only a few servings of fish and chicken a week. http://louis-j-sheehan.biz/ http://louis-j-sheehan.us/Blog/blog.aspx http://louis-j-sheehan.us/
Teammates nicknamed him China Study and razzed Mr. Gonzalez if he missed a block. But he wasn't ready to give up his new diet completely. After a preseason practice, he accompanied Mr. Hinds to learn a skill he believed as important as blocking techniques: how to shop for groceries. Mr. Hinds showed him nutritious fish oils and how to pick out breads dense with whole grains, nuts and seeds. "The best bread for you," says Mr. Hinds, "is if I hit you with it, it hurts." Mr. Gonzalez also learned how to make the fruit and vegetable shake he drinks each morning. He stocked his pantry with tubs of soy protein powder and boxes of organic oatmeal; soy milk and Brazilian acai juice crowded the fridge. His favorite dessert became banana bread topped with soy whipped cream from the vegan cafe near his home in Orange County's Huntington Beach.
Mr. Gonzalez soon recovered his lost pounds and strength, but prospects for a record-breaking season were still in doubt. The team lost its starting quarterback, Trent Green, in a trade, and the Chiefs' star running back was tied up in a contract dispute.
As the season progressed, the team lost more games than it won. But Mr. Gonzalez managed to stick to his diet and hold onto the football. He broke the touchdown record before midseason and was within reach of the career reception record. "I was like, 'OK, this is working,'" he says

Geologists and biologists know where to look for the earliest life--but the rocks are hard to read FOR TODAY'S CIVILIZED WORLD, WITH ITS DOT-coms, sitcoms, ATMs, and ATVs, the first 3.5 billion years of life on Earth are a bit of an embarrassment. It was only a few hundred million years ago that trilobites prowled the seas. More primitive life subscribed to two or three basic lifestyles: algal mat, spineless worm, or bacterial blob. Before that, in the Archean Eon more than 2.5 billion years ago--well, that kind of life is what Lysol is for. Scientists, of course, see it differently. "Almost everything of any biological importance happened back in the Archean," says Andrew Knoll of Harvard University, author of the upcoming book Life on a Young Planet. Soon after the infant Earth cooled down, he says, primeval microbes began processing essential elements--carbon, sulfur, and nitrogen, among others--that allowed for the eventual emergence of higher life-forms, including us. To this day, says Knoll, bacteria still do the biosphere's heavy lifting. "We just sit back and live off the fruits of their labors." http://louis-j-sheehan.biz/ Folks like Knoll would like to know whom to thank for those first trophic cycles. But in the quest to identify Earth's earliest life, geology can look a lot like biology. It's not always easy to tell the dead organisms from the dead ends. One of the few things experts all agree on is where to conduct the search: in the three far-flung provinces that host the world's most ancient sedimentary rocks. Deposits in Australia, Greenland, and South Africa offer a cryptic view of the earth's surface as it was between 3.2 billion and 3.8 billion years ago. The deposits are made up of layers of accumulated particles that were later buried, heated, and compressed. Rounded pebbles and smoothed sand grains in the sediments indicate that they were seabeds, so any life they record would be marine. The oldest fossil of that life comes from a remote desert site in Western Australia called North Pole. The rocks there bear the marks of stromatolites--sizable mounds of mud and minerals trapped or precipitated by microbial colonies living in shallow ocean water. Modern stromatolites grow knee-high in Australia and the Bahamas, and the organisms that build them leave distinctive patterns in the mud pedestal that can't be duplicated by mere geologic manipulation. At North Pole, those patterns appear in rocks that are almost 3.5 billion years old. http://louis-j-sheehan.biz/ The sediment layers in the North Pole fossils are much finer than those in modern stromatolites, suggesting that much smaller life-forms inhabited them. Even so, there's evidence of a food chain of sorts. The principal architects of stromatolites are photosynthetic. They get their energy directly from sunlight instead of feeding off other creatures. But geochemists found the chemical signature of a microbe that was feasting on dead organic matter, a scavenger of sorts. "We had quite sophisticated ecological communities back then, even if they were just tiny little microbes," says astrobiologist Roger Buick of the University of Washington, who discovered the North Pole stromatolites. Unfortunately, the vestiges of microbial communities are far more conspicuous than the remains of their individual members. Lacking bones, shells, teeth, and other hard parts, the first Earthlings didn't fossilize well. In the oldest rocks, chemical leftovers may be the only evidence of animation. So it happens that the earliest evidence of life is not a lithic imprint but a skewed ratio of carbon isotopes in a chunk of rock from southwest Greenland. Microscopic globules of graphite in the rock, documented in 1999 by geologist Minik Rosing at the University of Copenhagen, are unusually low in a heavy carbon isotope that gets excluded when inorganic carbon is converted into living material. Rosing thinks the C-13-poor graphite globules might have come from free-living planktonlike organisms that fell to the seafloor when they died. Their remains, he says, are at least 3.7 billion years old. http://louis-j-sheehan.biz/ In 1996 geochemist Stephen Mojzsis, now at the University of Colorado at Boulder, trumped Rosing's find in a report of heavy-isotope depletion in graphite grains from the Isua formation in Greenland and another site on the Greenland island of Akilia. Mojzsis says the grains are 3.85 billion years old--the oldest yet. But his interpretations of both the biological markers and the rock itself have been put through the wringer. One of Mojzsis's former coauthors, geochemist Gustaf Arrhenius of the Scripps Institution of Oceanography, showed how the Isua carbon-isotopic ratio could arise by geologic activity alone, if certain iron minerals in the rock were melted and pressed together over time. He and other investigators also think that the putative sedimentary rocks are actually igneous formations that have been severely transformed by heat. Thus, rocks of advanced vintage seem to confound even the most basic geologic distinction: igneous, metamorphic, or sedimentary? "These rocks have been buried and cooked at least three times," says Buick. "They've been severely squashed and strained and tied in knots at least three times too. Then they sat around for at least a billion years and got polished by glaciers. These are not ordinary rocks." The ambiguity of chemical evidence leaves geologists hungry for a well-defined, and ideally photogenic, fossil or two. In the early 1990s they thought their hopes had been answered when paleobiologist William Schopf of the University of California at Los Angeles described microscopic structures embedded in a Western Australia formation almost 3.5 billion years old. In his report, dark, slender silhouettes appear in translucent sections of thinly sliced quartz. Schopf says the silhouettes are a complex carbon polymer made by chains of bacteria that may have been anchored to the seafloor. After examining hundreds of present-day microbes, he named 11 possible species in his collection and gave the back story in a 1999 book called Cradle of Life. His menagerie made the Guinness Book of World Records, as the Earth's oldest fossils. http://louis-j-sheehan.biz/ "I found a whole bunch of different things," says Schopf. "The question was, what were they?" Schopf decided that at least half could be cyanobacteria, or blue-green algae, the first organisms in the evolutionary record to produce oxygen. That challenges orthodox thinking about conditions on the young Earth, which would not have had a significant oxygen atmosphere for at least another billion years. When geologist Martin Brasier of the University of Oxford had a look at the structures, he decided Schopf was wrong, wrong, and wrong again. The tubes are too branched to come from bacteria, he says. The rock is an extrusion from a hydrothermal vent, not seafloor sediment. And the silhouettes are inorganic carbon injected by the vent and molded into suggestive shapes by the growth of mineral crystals. "Ancient filamentous structures should not be accepted as being of biological origin until all possibilities of their nonbiological origin have been exhausted," Brasier and his coauthors wrote in a report last year. http://louis-j-sheehan.biz/ The hubbub over Schopf's fossils has humbled disciples of early life. "People have become more critical about what they'll accept as evidence of biology," says Knoll. And, as demonstrated by the recent retraction of evidence for life in a Mars meteorite, the stakes are astronomical. Once biologists know where and how life emerged, astrobiologists will be better prepared to look for it elsewhere in the solar system. http://louis-j-sheehan.biz/If life on Earth was a freak accident born of unique and peculiar conditions, it's probably rare elsewhere. But, says Buick, "if life can arise quickly and easily, given the right environment, there might be quite a bit of it out there." Some of the earliest signs of life are found in ancient rock layers called banded iron formations. The iron was released by underwater volcanoes and precipitated from ocean water more than 2 billion years ago. Today the rock formations supply about 95 percent of the iron used to make steel.

The structure of DNA, the molecule of life, was discovered in the early months of 1953. Nine years later, three men were jointly awarded a Nobel Prize for this achievement, which has proved to be one of the most consequential in the history of science. James Watson and Francis Crick, who worked at the Cavendish Laboratory, in Cambridge, England, came up with the famous double-helix structure. The third man honored, Maurice Wilkins, was a scientist in London; although he worked at a rival lab, he did make available to Watson and Crick some of the experimental evidence that helped them clinch their discovery. The person actually responsible for this evidence, however, was not Wilkins but an estranged colleague of his named Rosalind Franklin, who had died four years before the prize was awarded.
For a decade after her death, Rosalind Franklin remained little known beyond the world of molecular biology. Then, in 1968, Watson published "The Double Helix," his rambunctious, best-selling account of the race to solve the structure of DNA. In its pages, Rosalind Franklin becomes Rosy, a bluestocking virago who hoards her data, stubbornly misses their import, and occasionally threatens Watson and others with physical violence—but who might not be "totally uninteresting" if she "took off her glasses and did something novel with her hair."
Friends and colleagues of hers mounted a counter-offensive, which was soon joined by feminist historians of science. Why did Watson create Rosy the Witch? Out of guilt for having used her evidence, which Wilkins showed him without her knowledge. Neither Watson nor Crick ever admitted to Franklin that they had relied crucially on her research; neither so much as mentioned her in his Nobel acceptance speech. Moreover, Franklin herself had made great progress toward identifying the structure of DNA. Had she not been the rare woman laboring in a patriarchal scientific establishment that limited her opportunities and stifled her talents, the triumph might well have been hers. So her partisans have contended. http://louis-j-sheehan.us/ImageGallery/CategoryList.aspx?id=a1206a74-5f7f-443f-97f5-9b389a4d4f9e&m=0
http://louis-j-sheehan.us/Blog/blog.aspx http://louis-j-sheehan.us/
"Since Watson's book, Rosalind Franklin has become a feminist icon, the Sylvia Plath of molecular biology, the woman whose gifts were sacrificed to the greater glory of the male," Brenda Maddox writes in "Rosalind Franklin: The Dark Lady of DNA" (HarperCollins; $29.95). This mythologizing, Maddox thinks, has done Rosalind's memory a disservice. One wouldn't guess from the "doomed heroine" caricature, for instance, that Rosalind enjoyed an international reputation in three different fields of research. Nor would one guess from Watson's depiction that, far from being frumpier than the average Englishwoman, she had actually brought with her to London elements of Christian Dior's New Look that she had picked up during her years in Paris. Maddox, who has previously written lives of D. H. Lawrence and Nora Joyce, tells Rosalind's story engagingly. We get a vivid picture of her scientific prowess, the complexity of her character, and the stoicism with which she pursued her research during her final months even as she was dying of ovarian cancer. Inevitably, though, it is her part in the DNA drama which commands the most interest. Did she really play an indispensable role in the great 1953 discovery, as Maddox finally joins so many others in suggesting? Was she cheated of the credit due her because she was a woman?
Rosalind Franklin was born in London in 1920 to a prominent Anglo-Jewish family. (Her great-uncle had been installed by the British as the first High Commissioner of Palestine.) The one indulgence of her "frugal rich" parents was foreign travel; they favored vigorous mountain hiking trips—an activity that became a Wordsworthian passion for Rosalind. At sixteen, she chose science as her subject, selecting the "hard" areas of physics, mathematics, and chemistry rather than the botany and biology courses usually taken by girls. She avoided the social whirl. At the age of twenty-one, after three years of study at wartime Cambridge, she confessed to a cousin that she had never been kissed and did not know how the human ovum was fertilized. In 1945, she submitted a Ph.D. thesis on how the porosity of carbon was affected by heat, a subject she mockingly described as "the holes in coal."
http://louis-j-sheehan.info/page1.aspx http://louis-j-sheehan.info/
In fact, Rosalind's research predilections centered on something very beautiful, the idea of a crystal. To a mathematician, a crystal is a regular system of points that, if repeated indefinitely, will fill all of space. For a crystal in nature, such as table salt, these points are invisibly tiny atoms that are held in place by chemical bonds. In the early twentieth century, it was found that the wavelength of X rays is about the same as the space between atoms in crystalline matter. As X rays penetrate a crystal, they are deflected by the rows of atoms. This causes interference among them: some of the waves reinforce one another, while others cancel one another out. If a photographic plate is placed on the other side of a crystal being bombarded with X rays, a pattern of bright and dark spots eventually appears—a pattern that, in principle, would allow one to infer the molecular architecture of the crystal.
Rosalind eagerly absorbed the theory of crystallography, and so joined, as Maddox puts it, "the small band of the human race for whom infinitesimal specks of matter are as real and solid as billiard balls." Upon finishing her doctoral work, she got the offer of her dreams: a job at a crystallography lab on a quai up the river from Notre Dame. The four years that she spent in Paris, from 1947 to 1950, were evidently the happiest time of her life. Living in a garret in the Faubourg Saint-Germain, speaking almost accentless French, and working with a congenial and cultured group of scientists, she felt at home in a way she never had in England. The head of her labo was a dashing and brilliant Russian-born Jew named Jacques Mering, whose specialty was the study of "disordered matter"—crystals whose molecular arrangement was in some disarray. Rosalind picked up crystallographic expertise from Mering, and she also seems to have developed romantic feelings for him, even though he was already equipped with a wife and a mistress. Maddox speculates that Mering "made advances of some sort" to Rosalind, and that "she allowed herself to be tempted farther than was usual for her but eventually, incapable of a casual liaison, drew back." If so, it was probably the closest brush she ever had with carnal knowledge. As one of her fellow-chercheurs later put it, she was "like Queen Victoria about men."
Despite the pleasures of her life and work in Paris, Rosalind had always planned to return to London. In England, as in America, chemists and physicists were discovering a new research vista: life. The cells that make up an organism, after all, consist of atoms and molecules, which must obey the laws of physics and chemistry. It made sense, therefore, to try to bring the concepts and methods of the physical sciences to bear on biological mysteries. (After the creation of the atomic bomb, physicists found the prospect of escaping from the science of death to the science of life especially appealing.) Rosalind, though avowedly "ignorant about all things biological," applied for a position at the biophysics laboratory of King's College, London, and was accepted. Her arrival there, in 1951, marked the beginning of what Maddox calls "one of the great personal quarrels in the history of science."

The man who gave Rosalind the job in London, J. T. Randall, was something of a war hero in Britain because of his role in the development of radar. He was also happily out of step with the misogyny that prevailed in the scientific establishment at the time. Randall put women into more than a quarter of the positions in his lab and had a reputation for creating a helpful environment for them. The task he offered Rosalind was to investigate the structure of "certain biological fibres in which we are interested"—namely, DNA. This could scarcely have been a more important assignment. But the setting in which she was to carry it out filled her with gloom. King's College was dominated by clerics ("hooded crows," she called them) who trained students for the Anglican priesthood. The scientists were relegated to a cellar laboratory on the Strand, built around a bomb crater from the war. The atmosphere struck Rosalind as coarse and schoolboyish. Worse, her new colleagues were intellectually mediocre. As she wrote to a friend in Paris, "There isn't a first-class or even a good brain among them—in fact nobody with whom I particularly want to discuss anything, scientific or otherwise." The greatest indignity came when she found that she was expected to share the DNA project with the lab's deputy director, Maurice Wilkins, whom she soon decided she could not abide.
Wilkins was a New Zealand-born physicist who had worked on the Manhattan Project during the Second World War. He was unmarried and in his mid-thirties when Rosalind encountered him—tall, gauntly handsome, and attractive to women. His mild temperament, a little old-maidish perhaps, contrasted with Rosalind's brusque combativeness. She found him "middle class" and unworthy of being her collaborator. Wilkins made little gestures to win her favor, like buying her chocolates, but to no avail. When he gave a progress report on his own crystallographic research on DNA, Rosalind peremptorily ordered him to abandon X-ray work and stick to his optical studies. "Go back to your microscopes" is how he recalls her putting it.
http://louis-j-sheehan.net/ http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan-esquire.us/page1.aspx What Wilkins described on that occasion was evidence he had obtained which suggested that DNA had the form of a helix, rather like a spiral staircase. Helices were very much in the air at that moment. Only a few months earlier, Linus Pauling had published his discovery that certain proteins had a helical form. Pauling, who was working at Caltech, in Pasadena, was the foremost chemist of his time. Since he had discovered the structure of one important kind of biological molecule, it was natural for him to start thinking about DNA. Meanwhile, in Cambridge, at the Cavendish Laboratory, a thirty-five-year-old physicist named Francis Crick was becoming friends with a twenty-three-year-old American biologist named James Watson. Watson knew genetics; Crick knew X-ray crystallography. Impressed by Pauling's achievement, and having heard from Wilkins what the King's College lab was up to, they also turned their attention to the structure of DNA.
The stage was set for a three-way competition among London, Cambridge, and Pasadena. London, however, had an enormous advantage: a jam jar containing the best sample of DNA in the world. The gooey gel could be stretched out into long, fragile strings. "It's just like snot!" Wilkins exclaimed. Rudolf Signer, a Swiss scientist who had isolated the sample from the thymus glands of calves, had generously given it to Wilkins at a scientific meeting. How Signer managed to get DNA in such a pristine form is a mystery; he never fully explained his recipe. But it soon became clear that his gel could yield beautifully crisp diffraction patterns.
Upon Rosalind's arrival at King's College, the Signer DNA was turned over to her. Using state-of-the-art equipment, she began to get superb X-ray photographs. She also found that the Signer DNA fibres could be made to assume two distinct forms: a longer "wet" form, and a more compact "dry" one. All earlier X-ray photographs of DNA had been a confusing blur of the two. But when Wilkins pointed out that her patterns, too, were consistent with a helical structure, Rosalind snapped, "How dare you interpret my data for me?" His proposal of collaboration was angrily rejected. The atmosphere in the lab became so poisonous that Randall had to intervene, setting out a formal division of labor. Rosalind got all the Signer DNA and the new X-ray cameras. Wilkins was left with the old equipment and an inferior sample of DNA. And that was more or less the end of any communication between them.
Maddox does not hesitate to assign blame for all this. "The rift was Randall's doing," she writes. In inviting Rosalind to the King's College lab, he had sent her an ambiguous letter leading her to believe that she would be in exclusive command of the DNA project; it was understandable, the author implies, that she should resent Wilkins's continued involvement. Wilkins was not the only object of her animosity in the lab, however. "She nearly terrified the living daylights out of me," one graduate student recalled. Maddox attributes Rosalind's rebarbativeness to the patriarchal atmosphere of London: "In Paris she was confident, admired, independent. Now she was a daughter again." That may be; but it is also true that, less than a year after her return to England, Rosalind found herself in sole custody of all the experimental means needed to discover the structure of DNA.
In Cambridge, Watson and Crick had none of that. They did, however, enjoy a remarkable personal affinity. "Neither had an ounce of depression in him, while Rosalind and Maurice, in their very different ways, were prey to melancholy," Maddox writes. Watson and Crick's approach to the structure of DNA was inspired by the method that Linus Pauling had used so successfully with proteins: model-building. Guided by the rules of chemistry, they would make an educated guess about how DNA was put together, and construct a model out of metal rods and wires and colored plastic balls. No need to mess around with any snotlike gel. Rosalind had nothing but scorn for this speculative approach. Even if one managed to slap together a model that satisfied the X-ray data, how could one be sure that it was the only model that would do so? How would one know, she wondered, whether it was "the solution or a solution"?http://louis-j-sheehan-esquire.us/ http://louis1j1sheehan1esquire.us/page1.aspx http://louis1j1sheehan1esquire.us/ http://louis-j-sheehan.org/page1.aspx http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx
What everyone at the time did know about DNA was that it consisted of a sequence of four different bases attached to a sugar-phosphate chain. These bases were adenine, guanine, thymine, and cytosine (usually abbreviated A, G, T, and C). The precise sequence presumably encoded the genetic information. As for the over-all architecture, it seemed reasonable to start by assuming that DNA was a helix. Pauling had already shown that a helical structure could lend stability to large biological molecules, and the preliminary X-ray evidence for DNA jibed with this hypothesis. But what kind of helix? And would its structure shed light on the molecule's singular function—self-reproduction?
In late 1951, Watson went down to listen to the London team talk about what they had learned so far, and he returned to Cambridge with a slightly garbled memory of their data. A week later, he and Crick had come up with a model for DNA. It was a triple helix, with the bases facing outward, so that they could interact with proteins. They invited the King's College group up to see their handiwork. It got a withering reception. Rosalind—who, unlike Watson and Crick, was actually a chemist—pointed out that the molecule as they had constructed it would not even hold together. Maddox reports that Rosalind was "jubilant" on the train back to London: "She had not expected the model to be right. The whole approach was unprofessional." Watson and Crick tried to salvage matters by suggesting that the two groups join forces, but Rosalind wanted nothing to do with them. After this debacle, the director of the Cavendish lab, Sir Lawrence Bragg, ordered Watson and Crick to leave the investigation of DNA to King's. As a token of compliance, the pair even sent their model-making jigs down to London, where they remained idle.
Rosalind, who now had the field pretty much to herself, was intent on deducing the molecular structure of DNA directly from the spots on the X-ray pictures, without any imaginative guesswork. Such a deduction would entail endless rounds of laborious calculation. Undeterred, Rosalind plunged in. She and her assistant also continued with their X-ray photography, taking long exposures—some lasting a hundred hours—of a single fibre of DNA. Sometime in the spring of 1952, she obtained the most stunning pattern yet for the wet form: a stark, X-shaped array of black stripes radiating out from the center. It fairly shouted helix. Rosalind numbered it Photograph 51 and put it aside. She was more interested in the dry-form photos, which contained the complex detail that, with fastidious measurement, might enable her to compute the form of DNA. And this detail did not point to a helical structure. That July, in an uncharacteristic prank, she even conducted a mock funeral for the helix. She spent the next few months with her slide rule, buried in books of numerical tables.
Maddox finds her earthbound approach understandable, given what she sees as the "hostile environment" in which Rosalind found herself: "If she had felt very confident and supported, she might have been able to make outrageous leaps of imagination." Maybe, though, she sensed little urgency to do so. Watson and Crick had been banned from investigating DNA. Pauling was still finishing up his work on proteins; and, in any case, as Rosalind knew, the only DNA photographs he had were old ones in which the two forms were deceptively superimposed. As for Wilkins, next door, he was too cowed to ask Rosalind for her data, much less for some of the precious DNA sample that had originally been his. http://louis1j1sheehan1esquire.blogspot.com/ http://louis0j0sheehan0esquire.blogspot.com/ http://louisjsheehan.blogspot.com/ http://louis9j9sheehan.blogspot.com/ http://louis7j7sheehan.blogspot.com/ http://louis6j6sheehan.blogspot.com/
Watson and Crick, as it happened, could also afford to be patient. They were confident that Rosalind, in rejecting the helix, had headed up a blind alley. Crick saw how she had been misled by her painstaking measurements: the supposed anti-helical features in her photographs, he realized, were actually distortions that arose in the DNA helix when it coiled up into the dry form. Watson and Crick's method was the opposite of Rosalind's: trust no datum until it has been confirmed by theory. They were determined to solve the structure of DNA with as few empirical assumptions as possible.
Besides, what real data did they have access to? Rosalind was not publishing her X-ray photographs of DNA. Watson and Crick had heard about them from Wilkins, but not even he had seen the extraordinary Photograph 51. In May of 1952, Pauling was to be the guest of honor at a Royal Society meeting on proteins in London. Had he attended, he might well have been shown Rosalind's photographs and picked up from them what he needed to solve the structure of DNA. But the trip was aborted; because of McCarthyist suspicions about Pauling's political sympathies, the United States State Department had refused to issue him a passport.
Pauling pressed ahead with his model-building all the same, relying on his unrivalled grasp of the geometry of chemical bonds. At the end of 1952, Watson and Crick were devastated by the news that Pauling had worked out a structure for DNA. They awaited his paper with trepidation, but when it arrived, on January 28, 1953, they were delighted to find that Pauling had made the same blooper they had more than a year earlier. Like their old model, his was a chemically defective three-stranded helix with the bases on the outside. Watson and Crick knew that Pauling's errors would be pointed out to him, and that, given a second crack at the DNA problem, he would probably solve it. They figured they had, at most, six weeks.
That same day, Rosalind was giving her final seminar at King's College. She had had enough of that basement full of "positively repulsive" mediocrities, and had accepted an invitation from the great crystallographer J. D. Bernal to join his lab in London, at Birkbeck College. She would leave off DNA research and apply her X-ray skills to the study of viruses. Summarizing her work at King's, she neither referred to the wet form of DNA nor showed the splendid photographs she had taken of it. Instead, she concentrated on her supposed evidence that the dry form of the molecule was not helical. http://louis5j5sheehan.blogspot.com/ http://louis4j4sheehan.blogspot.com/ http://louis2j2sheehan.blogspot.com/ http://louis1j1sheehan.blogspot.com/ http://louis0j0sheehan.blogspot.com/ http://louis3j3sheehan3.blogspot.com/ http://louis8j8sheehan8.blogspot.com/ A couple of days later, Watson turned up in her lab unbidden, offering to show her Pauling's model. When she countered with her anti-helical evidence, Watson, by his own account in "The Double Helix," decided to "risk a full explosion" by implying that she was incompetent in interpreting her own X-ray pictures: "Suddenly Rosy came from behind the lab bench that separated us and began moving toward me. Fearing that in her hot anger she might strike me, I grabbed up the Pauling manuscript and hastily retreated to the open door." Watson then encountered Wilkins, who, he claimed, told him that some months earlier "she had made a similar lunge toward him." Wilkins proceeded to do something that has widely been deemed unethical: he showed Watson one of Rosalind's photographs—probably Photograph 51. "The instant I saw the picture my mouth fell open and my pulse began to race," Watson recalled. On the train back to Cambridge, he sketched from memory, in the margin of a newspaper, the pattern he had seen.
From this point on, Watson and Crick needed only one month to wrap up the matter. Bragg authorized the two to resume their model-building, with jigs to be turned out by the machine shop. Watson plumped for a helical structure with two chains. "Francis would have to agree," he later wrote. "Even though he was a physicist, he knew that important biological objects come in pairs." Then they had a couple of lucky breaks. Crick noticed a symmetry in DNA that had eluded Rosalind and her colleagues: the crystal had the same form when it was turned upside down. As he immediately realized, this meant that the two chains that made up the helix must run in opposite directions, like up and down escalators. Their second break came when an off-the-cuff remark made by a new lab mate (a former student of Pauling's, as it happened) supplied the necessary clue to how the two chains of the helix held together. As they'd begun to suspect, it was the bases that bonded. Whenever A occurred on one chain, T was invariably paired with it on the other; http://Louis-J-Sheehan.us/ http://louis-j-sheehan.us/page1.aspx the two fit snugly together because of their shapes. Ditto for C and G. Therefore, one chain of the double helix was an upside-down negative of the other. When separated, each might serve as a template on which a new, complementary chain could be assembled with exactly the same information as the old. That, Watson and Crick realized, was how the molecule reproduced itself, and how nature, for the last four billion years, had counteracted the tendency of matter to become disordered. At lunchtime on February 28, 1953, Watson recounted, his partner "winged into The Eagle"—a Cambridge pub—"to tell everyone within hearing distance that we had found the secret of life." That April, the two presented their model, in a nine-hundred-word prose poem, in the scientific journal Nature. The elegance with which the DNA structure merged form and function seemed to guarantee its truth. "It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material," the authors demurely noted.
Rosalind was not bowled over by Watson and Crick's model. "It's very pretty, but how are they going to prove it?" was her reaction. Rosalind, Maddox writes, "had been trained, as a child . . . as an undergraduate, as a scientist, never to overstate the case, never to go beyond hard evidence." Had Rosalind been a man, the author suggests, she might have been encouraged to be more audacious. Yet a knack for guessing at an answer ahead of the evidence is one of the things that distinguish a great scientist from a good one, regardless of gender. Perhaps Rosalind was merely a very good scientist, not a great one. Or, perhaps, given a little more time, she would have discovered the structure of DNA herself. Crick has generously ventured that she was three months away, but it is doubtful that Rosalind realized it, given her decision to leave the investigation of DNA to take up the crystallographic study of viruses. http://louis-j-sheehan.us/Blog/blog.aspx
Still, as Maddox notes, "Rosalind's Photograph 51 was the pivotal moment in the discovery of the double helix." Doesn't that make her partly responsible for that discovery? Well, there are two senses of "responsible": a moral sense and a causal sense. Rosalind was not morally responsible for the discovery, because she didn't willingly share or publish her most important data and she spurned would-be collaborators, including Watson and Crick. It was Wilkins who showed Photograph 51 to Watson. Maddox absolves Wilkins of the charge that it was unethical of him to have done so, but still maintains that Wilkins's action was "unwise." It is hard to see why. The ban on Watson and Crick's working on DNA had nothing to do with gentlemanly fair play; it was an attempt to allocate scientific resources efficiently—resources that were quite scarce in postwar Britain. Besides, Rosalind had already had the photograph for nine months without interpreting it correctly—whereas Watson saw its significance at a glance. What was unwise—and a little cowardly—was Watson and Crick's unwillingness to admit to Rosalind that they had been given access to her photograph, and their failure to acknowledge her experimental work more graciously, at least during her lifetime.
Was Rosalind, then, at least causally responsible for the DNA discovery, in the sense that it would not have happened without her? It is true that Photograph 51 helped to confirm the double-helix model. As Watson wrote in the epilogue to "The Double Helix" (added to make amends for his waspish treatment of Rosalind in the book), "The x-ray work she did at King's is increasingly regarded as superb." But she had been entrusted with the best DNA sample and the most sophisticated fine-focus cameras. There is no reason to think that Wilkins, had he been given charge of these resources, would not have obtained comparably crisp X-ray photographs—or, at least, some that were good enough to yield the few basic measurements that Watson and Crick needed.
Rosalind's later scientific career was highly successful and relatively happy. She travelled extensively in the United States, lecturing on coal to "the carbon crowd" and on the crystallography of viruses to scientific audiences. She had friendly encounters with Jim Watson (who by now had become something of a celebrity, appearing in an issue of Vogue opposite Richard Burton). America seemed to bring out the sunny side of this sometimes dour woman. "I have completely fallen for Southern California," she wrote in one of the many letters quoted by Maddox. (Among her Fanny Trollope-like observations was that Americans "seem to make nearly all their own furniture. It is a curious result of high standards of living—everybody earns a lot, so nobody can afford to pay anybody else.") While Rosalind was in California, around her thirty-sixth birthday, she became aware of persistent pains in her lower abdomen. Less than two years later, she was dead of ovarian cancer. It seems likely that her constant exposure to X rays was one of the causes. http://louis-j-sheehan.us/Blog/blog.aspx
Had Rosalind lived, would she have shared the 1962 Nobel Prize awarded for the discovery of the double helix? Maddox poses this inevitable question, only to banish it to the same idle file as "What if Kennedy had not gone to Dallas?" It's unlikely that Rosalind would have been named a co-winner along with Watson, Crick, and Wilkins, for the Nobel committee's practice—later codified as a rule—is never to divide a prize among more than three people. But Wilkins's claim to the laurel was surely weaker. His main contribution to the discovery of the double helix was not his experimental work, which was minimal after Rosalind's arrival, but his role as a go-between for the London and the Cambridge labs.
Another "what if" is worth considering. What if Linus Pauling had had access to one of Rosalind's photographs? Pauling's command of stereochemistry had already enabled him to work out the helical structure of proteins single-handedly. The information he had about DNA was meagre, though, and had been gleaned from old X-ray images that were a misleading blur of its wet and dry forms. Had Pauling come to London and had a glance at Photograph 51, he would surely have deduced the correct structure as quickly as Watson and Crick did. But Pauling was a campaigner against nuclear weapons. A witness before a committee of the House of Representatives had accused him of Communist sympathies. He was kept from seeing the King's College X-ray pictures by a State Department travel ban. As it happens, Pauling did win a Nobel Prize, his second, in 1962, the same year that Watson, Crick, and Wilkins did; but his was for peace.

Scientists longing to sneak a peek at the molecular machinery of living cells came one step closer to that goal in March with the creation of lenses that break the limits of current light microscopy.
Electron microscopes can already capture the realm of the supersmall, but the sample preparation and imaging conditions make it impossible to observe live cells. Optical microscopes are great for viewing living samples, but their resolution is limited by the properties of light. Now two teams of researchers have devised unconventional lenses that could capture the nanoworld without killing it.
One group, led by Xiang Zhang of the University of California at Berkeley and Lawrence Berkeley National Laboratory, created a “hyperlens” that bends light in a way no ordinary material can. “Natural materials prevent some of the waves from coming through to the camera,” Zhang says. “You lose certain kinds of waves, called evanescent waves, which don’t travel far. That blurs the image.” But the layered structure of his half-cylinder-shaped hyperlens preserves these evanescent waves, allowing incredibly tiny objects to be resolved. The second team, led by Igor Smolyaninov at the University of Maryland, created a “superlens” with concentric rings of acrylic on a gold film surface. The lens can be used to see objects on the scale of small viruses. “If we’re successful in this work,” Smolyaninov says, “we will hopefully be able to visualize what is going on inside cells.” http://louis-j-sheehan.biz/page1.aspx http://louis-j-sheehan.biz http://louis-j-sheehan.biz/
When the dinosaurs died out some 65 million years ago, many perished in the exact same iconic pose: neck, spine, and tail curved backward, mouth open, limbs contracted. The reason for this characteristic dino death pose has been unclear. Conventional wisdom held that the dead dinos’ pose was struck when the muscles contracted under rigor mortis or because the dinos’ tendons and ligaments had dried up, suggesting that their bodies had been exposed to the sun for a long time. But if so, why hadn’t the bones been scattered by scavengers?
Now the answer is coming from the corpses of some modern-day birds and mammals, which look very similar when they have died under certain specific conditions. The connection was never made before because paleontologists rarely see dead parrots. But veterinarians do. And luckily, Cynthia Marshall Faux is both—with doctorates in veterinary medicine as well as geology (with a specialty in vertebrate paleontology).
It was clear to Faux that the dinosaurs’ pose was a sign of opisthotonos, a condition that results from an injury affecting the cerebellum, which regulates fine muscle movement. While working at the Museum of the Rockies in Bozeman, Montana, Faux collaborated with Kevin Padian, a professor of integrative biology and curator of the Museum of Paleontology at the University of California at Berkeley, to make her argument: Brain injury during death, not later rigor mortis, explains the typical look of dino fossils. “Paleontologists are familiar with dead things,” says Faux, who is a vet in Idaho. “But I know about dying things. I see animals die all the time. I see the process, not just the result.” http://louis-j-sheehan.org/page1.aspx http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx
Adding to the intrigue is that opisthotonos is usually seen in warm-blooded animals like birds and mammals but not reptiles. Faux’s paper on opisthotonos, published in March, rethinks dinosaurs not just as having died for reasons other than meteor impacts and volcanic eruptions but also advances the argument that these creatures may have had hot blood pumping through their veins.
Darwinian natural selection is at work among the communities living in the Tibetan mountains, according to Case Western Reserve University anthropologist Cynthia Beall. She reported at the American Association of Physical Anthropologists meeting in March that women who carry more oxygen in their blood have more than twice as many surviving children as women who carry less oxygen. “We determined that the strength of natural selection at altitude was even stronger than the strength of natural selection by falciparum malaria, and that is the classic example,” Beall said.
Women who carry at least one copy of a gene variant, or allele, that codes for high oxygen saturation had 125 percent more surviving children than those who carry two copies of a low-saturation allele. By contrast, women who carry a sickle-cell allele, which protects against malaria, have only about 50 percent more surviving children in malaria-infested regions than women lacking the variant.
Beall’s team hasn’t yet identified the gene that provides such protection, but that’s next on her agenda. In the meantime, she thinks the reason the selective difference at altitude is so large is that the altitude is constant, affecting people every day. Malaria, on the other hand, ebbs and flows over time, so the physiological benefits associated with the sickle-cell allele may be tempered. http://louis-j-sheehan.net http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx http://louis-j-sheehan.info http://louis-j-sheehan-esquire.us/page1.aspx
The mass of the new-found "X" particle which scientists have been discovering in cosmic ray research may not have a fixed value, says Dr. Seth H. Neddermeyer of the California Institute of Technology.
Dr. Neddermeyer is a colleague of Dr. Carl Anderson and worked with him when the latter made the discovery of the positron for which he received the Nobel Prize award. The team of Anderson and Neddermeyer, too, made the initial discoveries of the "X" particle, whose mass appears to be intermediate between that of the electron and the proton.
"There are . . . reasons for believing that the mass (of the X particle) may not be unique and that many masses, ranging from a few times the electron mass up to very large values, may exist," says Dr. Neddermeyer's report, in part.
By theory, explains Dr. Neddermeyer, photons of radiant energy create pairs of particles—positive and negative in electrical sign—in their rush through the atmosphere on their way to Earth. The energy and mass possessed by these new particles, which are the offspring of dying photons, are variable, postulates Dr. Neddermeyer. Thus many different masses might be observed, depending on the energy possessed by the original photon that creates them.
The point is that particles can have two kinds of mass; the so-called rest mass and a mass due to motion. Theoretically, at least, a particle moving with the speed of light should have an infinitely large mass.
The second kind of mass, which varies with the speed of the particle, was observed in the present experiments. http://louis-j-sheehan.us/ImageGallery/CategoryList.aspx?id=a1206a74-5f7f-443f-97f5-9b389a4d4f9e&m=0

Tusks scattered on the frozen shore of Siberia opposite Alaska may mean that Soviet scientists will some day add more complete specimens of the extinct hairy mammoth to the two bodies already found, Tass, Soviet news agency, reported.
Detailed information on the body, the second one to be found, reached Moscow. It revealed that this hairy mammoth, as it existed thousands of years ago, was in the neighborhood of 18 feet long, had a trunk more than 9 feet long and hair more than 3 inches long.
Like the first specimen found, the second body, which was uncovered last October, was partially damaged by wild animals. The head, one leg, and a part of the trunk have been partly eaten away. Otherwise, the body is intact, preserved through the ages in the frozen earth of the north, as effective an icebox as man has devised.
The tusks of the specimen found have not yet been located, but they may be under its body, which has not yet been removed from the pebbly ground. Next spring, when the sea in this area is clear of ice, soundings of the coastal zone will be taken to see if a ship can approach the shore to take on board the find.

UFO investigators flock to Stephenville, Texas!
A team of six investigators from the Mutual UFO Network will be interviewing citizens of Stephenville, Texas who say they spotted an Unidentified Flying Object at sunset on January 8th.
The Mutual UFO Network is a non-governmental group interested in documenting UFO's. State director Ken Cherry says the network has received calls from 50 citizens who say they witnessed the UFO and that the number and credibility of the people is exceptional.
The rural Texas town has attracted world wide attention after the sightings. The Local Newspaper, the "Stephenville Empire-Tribune" has received calls from as far away as Finland and Japan as people remain fascinated about the reports of a giant bright object in the sky that witnesses say was a mile long.
It remains the talk of the town and the Stephenville High School Science Club is now selling T-shirts to cash in on the craze.
Stephenville prides itself on being the dairy capital of Texas and the shirts that sell for ten dollars have a picture of a Holstein cow being beamed up to a flying saucer.

More than 30 residents of Stephenville, Texas, claim to have seen a UFO, described as a mile-wide, silent object with bright lights, flying low and fast. And now it's actual front-page news. So what was it?
"It was very intense, bright lights," said local newspaper reporter Angela Joyner.
"The lights were like going like this," said Constable Leroy Gateman making hand gestures to describe what he saw when he spotted the UFO.
Rick Sorrells says he saw it while he was hunting deer in the woods.
"You look at the trees, and it was right here," Sorrells told ABC News correspondent Mike Von Fremd as he showed him the location in the woods where he spotted the UFO.
Steve Allen, a 50-year-old pilot, was at a campfire with friends and says the object was a mile long and half a mile wide. "I don't know if it was a biblical experience or somebody from a different universe or whatever but it was definitely not from around these parts," Allen said.
Allen drew a sketch of the object, which he said traveled at amazing speed without making a sound. While drawing, Allen told Von Fremd that he saw "an arch shape converted in a vertical shape, and then it split and made two of them, and then these turned into just fire and it was gone."
A spokesman for the 301st Fighter Wing in Fort Worth says no aircraft from his base was in the area, and says the objects may have been an illusion caused by two commercial airplanes. But those who saw the lights don't buy that explanation.
"It's an unidentified flying object," insisted a former Air Force technician. http://louis-j-sheehan.org http://louis-j-sheehan.org/
"It was so fast I couldn't track it with my binoculars," said Gateman.
Constable Leroy Gateman describes what he saw in the sky.
Some in Stephenville are a bit embarrassed about all the attention. "It's crazy," said one teenage girl in town.
"A lot of folks aren't used to this kind of thing. They are not UFO nuts or anything like that around here," said City Councilman Mark Murphy.
Like it or not, all eyes are now trained on the sky over Stephenville to see whether any mysterious flying objects make a return.
Cue the Twilight Zone theme ... Dozens of people say they saw a UFO hovering over their rural community near Stephenville, Texas. The Stephenville Empire-Tribune says at least 40 people have reported sightings of the object, which reportedly appeared in the sky just after 6 p.m. on Jan. 8.
Lee Roy Gaitan, a local police officer, tells the newspaper: I was outside with my eight-year-old son, Ryan, when I saw lights. It was like nothing I've ever seen before. It was dark already. At first it was two red burning glows that went away and then came back on. I went inside to tell my wife. When I came back out I saw something like lights you'd see in a bar. My little boy and I counted and we came up with nine flashes and they were real spread out. But I couldn't see them attached to anything, just the lights. So I went to my pickup and got my binoculars to see if I could see a plane or something. Even with the binoculars there was no outline. It started moving towards Stephenville and moving so fast I had trouble following it with my binoculars. It covered a big area. It sounds crazy but we really saw what we saw. http://louis-j-sheehan.net http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us
The paper has more eyewitness accounts, including this one from pilot Steve Allen: The ship wasn't really visible and was totally silent, but the lights spanned about a mile long and a half mile wide. The lights went from corner to corner. It was directly above Highway 67 traveling towards Stephenville at a high rate of speed - about 3,000 mph is what I would estimate.
Chuck Mueller, a helicopter pilot who served in Iraq, says he saw unusual lights on the horizon a few days after the UFO sightings were reported near Stephenville.
Mueller tells KXAS-TV that he was flying a medical helicopter around dusk when "we saw the lights come on, one little orange light, and then another one and another one in sequence across the sky." He was shocked at first, but then concluded that the lights, which appeared to be more than 30 miles northeast of the original sightings, were coming from flares that were dropped over the Brownwood Military Operations Area.
There's just one problem with that theory. The NBC station says the military didn't have any planes in the air at the time of the original sightings.
A spokesman for the 301st Fighter Wing at the Joint Reserve Base Naval Air Station tells the Associated Press that he's convinced there's a logical explanation for the lights. "I'm 90 percent sure this was an airliner," Maj. Karl Lewis tells the wire service. "With the sun's angle, it can play tricks on you."
The sightings are big news in rural Texas. The top item on the Stephenville Empire-Tribune's website tells readers where to report a UFO sighting and, below that, the paper notes that a local businessman is offering a $5,000 reward for "video that would confirm a UFO sighting in Selden on Jan. 8."
They're also big news around the world. "The reported sightings have become a catalyst on blogs and in chat rooms, triggering scientific and philosophical debates, religious inquiries, conspiracy charges and bad Texas jokes," the Star-Telegram reports.
The Mutual UFO Network is holding a meeting this weekend for people who saw the object. The non-profit group says its investigators will begin taking statements at 1 p.m. on Saturday. http://louis1j1sheehan1esquire.us/page1.aspx http://louis1j1sheehan1esquire.us http://louis-j-sheehan.org/page1.aspx http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx
The Star-Telegram says this isn't the first time people in that part of the state have reported seeing strange things in the sky. Back in 1897, a Stephenville man told The Dallas Morning News that a 60-foot-long "aerial monster" landed on his farm.
Faster than a speeding bullet — and bigger than a Wal-Mart.
That's how residents near the west Texas town of Stephenville described an object they spotted in the sky one night last week.
Dozens of the town's residents — including a pilot and a police officer — said a UFO hovered over the farming community for about five minutes last Tuesday before streaking away into the night sky.
Pilot Steve Allen saw the object when he was out clearing brush off a hilltop near the town of Silden. Allen described the unidentified object as being an enormous aircraft with flashing strobe lights — and it was totally silent.
He said the UFO sped away at more than 3,000 mph, followed by two fighter jets that were hopelessly outmaneuvered. Allen said it took the aircraft just a few seconds to cross a section of sky that it takes him 20 minutes to fly in his Cessna.
The veteran pilot said the UFO, an estimated half-mile wide and a mile long, was "bigger than a Wal-Mart."
Military Dismisses Sighting
The Stephenville Empire-Tribune, which has written about the mysterious object, said about 40 people saw the thing — though some were too sheepish to admit the sighting until others came forward.
Police officer Leroy Gatin said he was walking to his car when he saw a red glow that reminded him of pictures he'd seen of an erupting volcano.
He said the object was suspended 3,000 feet in the air. Gatin said he was so awestruck that he called his son to come and see — but he didn't talk much about it until he saw a story about a UFO in the local paper. http://www.soulcast.com/post/show/106438/Louis-J-Sheehan-68336

Military officials, however, were skeptical. They said the residents are letting their imaginations run wild and passed it off as an optical illusion. They said it was likely nothing more than a reflection of sunlight on two airliners.
Officials at a nearby air force base also said their fighter pilots didn't chase down anything that night.
The incident was eerily similar to a UFO sighting a little more than a year ago at Chicago's O'Hare International Airport.
As many as 12 United Airlines employees spotted the object and filed reports with United.

Combining a megapowerful magnet, multiple detectors, and carefully tweaked contrast, a new MRI technique developed at the National Institutes of Health (NIH) provides an unprecedented look at the fine structure of the brain. Using an MRI machine equipped with a magnet more than twice as powerful as one in an ordinary device, the researchers created a way to measure the magnetic field changes caused by tissue properties to optimize contrast in the image. They were also able to compensate for the magnetic field fluctuations created by the patients’ breathing. The technique revealed never-before-seen patterns in the white matter and gray matter of the human brain.
Picking up on such differences may help researchers look more deeply into the brain’s subdivisions, allowing them to map it in greater detail. It may also bring about advances in diagnosing diseases like Alz–heimer’s and multiple sclerosis, both of which involve abnormal iron accumulation in the brain. For patients, the new technique may mean that “you could more accurately—and maybe earlier—diagnose a disease,” says NIH physicist Jeff Duyn. Only eight MRI machines this powerful exist in the United States, and all are housed in research, rather than clinical, settings. Each costs around $5 million, and that’s before the expense of setup—which includes installing 380 tons of shielding material to prevent every metal object in the building from being sucked into the magnet. http://louis-j-sheehan.us/ImageGallery/CategoryList.aspx?id=a1206a74-5f7f-443f-97f5-9b389a4d4f9e&m=0

Chinese researchers announced (pdf) in March that they had created glass that can be bent into right angles without shattering. But this isn’t glass as we know it: The new glass is opaque, twice as strong as window glass, and made of metal.
As solids, metals have an orderly atomic structure; in liquid metals, the arrangement becomes random, as in glass. To create metallic glass, scientists supercool liquid metals, effectively “freezing” the random array in place. These bulk metallic glasses, or BMG, are two to three times stronger than the crystalline form of the metals.
Superstrong BMG has already been used in the manufacture of high-tech golf clubs and tennis rackets; in 2001, the collector on NASA’s Genesis spacecraft, which caught particles from the solar wind, was made of BMG. But since the 1980s, when scientists began making BMG, the materials have exhibited a fatal flaw. Paradoxically, the stronger they are, the more vulnerable they are to cracks, says Wei Hua Wang, a physicist who helped develop the new glass at the Chinese Academy of Sciences. A tiny fracture in the original type of BMG spreads quickly and becomes catastrophic.
http://louis-j-sheehan.info/page1.aspx http://louis-j-sheehan.info
To create a glass that is both strong and flexible, Wang and his colleagues altered an existing BMG recipe, combining zirconium, copper, nickel, and aluminum. Realizing that small changes in the metal mixture would lead to large variations in brittleness, they sought a combination that would keep cracks from spreading. “The plasticity of the glass is very sensitive to the composition,” Wang explains.
After two years, the scientists produced bendable BMG. It contains hard areas of high density surrounded by soft regions of low density. The result: When a crack begins in one place, it dissipates quickly in the surrounding regions, leaving the whole flexible. http://louis-j-sheehan.info/page1.aspx http://louis-j-sheehan.info
Believe it or not, there are some folks who make a living as professional guinea pigs in tests of experimental drugs. Some question whether testing that relies on frequent lab fliers takes advantage of poor people or compromises the quality of the data.
In a recent issue of the New Yorker, bioethics professor Carl Elliot, from the University of Minnesota, details how early drug safety testing has become more of a business transaction than a scientific endeavor in an article called “Guinea-Pigging.” He’ll also be exploring the topic as part of a book he’s writing on corruption, money and medicine that he expects to be called “White Coat, Black Hat” and to be published next year. We asked Elliot, who is on sabbatical in New Zealand, a few questions via e-mail. Here are the highlights of the long-distance conversation:
How does professional guinea-pigging affect the data on experimental drugs?
What I heard about most often was subjects stretching the truth about their medical histories in order to get into high-paying studies. That seems to be fairly common. I don’t know what kind of impact it has on the results, but it shouldn’t be terribly shocking. We have a safety testing system where subjects don’t have any stake in the results of the study, where they don’t really trust the research sponsors, and where they don’t believe they are going to get access to the drugs that are developed by the studies. If poor people are being asked to test drugs for the benefit of rich people, then we shouldn’t be surprised if the poor people are not always perfectly compliant.
Should we change the system to discourage professional guinea-pigging?
Well, one thing that worries me is the damage that all these studies could be doing to the long-term health of the guinea pigs. They are mostly uninsured, so they are in no position to get regular medical care, and nobody else has any financial interest in monitoring their health.
Payment itself is a real dilemma. New drugs need to be tested for safety, and I can’t imagine that many people will volunteer to test the safety of new drugs for free anymore, especially if it means checking into a testing site for three weeks to undergo invasive medical procedures. But it feels unfair to put the burden on poor people who are driven to volunteer at these testing sites because they can’t get any other kind of work. If we are going to have a payment-based system, we need to make sure that poor subjects are not being exploited.
What changes are needed for safety’s sake?
Apart from watchdog groups like Circare, which operate on a shoestring budget, and investigative reporters, there really are very few people outside the research enterprise watching these studies. Formal oversight has been outsourced to for-profit IRBs [institutional review boards], which are paid by the companies doing the research, and which mainly look at studies on paper. The complaints I often heard about from guinea pigs were conditions on the ground that IRBs have never really thought much about. I don’t think it ever occurred to an IRB to ask SFBC [SFBC International, a company that owned the largest drug-testing site in North America] whether they were testing drugs on undocumented immigrants in a dilapidated motel. Some testing sites have procedures that are not really dangerous, but which are uncomfortable or degrading, like requiring subjects to have a rectal exam whether or not it is relevant to the study. And of course, somebody needs to make sure that researchers who are crooked or incompetent are not allowed to keep doing research. http://louis-j-sheehan.biz/page1.aspx http://louis-j-sheehan.biz http://louis-j-sheehan.biz/
What can or should be done for participants who are injured or suffer other side effects during a trial?
The very least that can be done is to guarantee that they will get medical care without being stuck with the bill. As things stand now, guinea pigs can’t even count on that. That’s not just a problem with industry studies. Even subjects in federally sponsored trials in universities don’t get that guarantee. Robert Steinbrook published a piece in the New England Journal of Medicine a couple of years ago showing that only 16% of academic health centers in the U.S. provided free care to injured subjects, and none of them compensated subjects for pain and suffering.
Where do you see this process of human subject testing headed?
It’s heading overseas to the developing world. It’s less expensive and the oversight is less rigorous. I think the problems will be the same as here, only more so. http://louis-j-sheehan.org http://louis-j-sheehan.org/
The sequel is out there.
The conspiracy theories will not be.
Ten years after the first film and six years after the show went off the air, The X-Files returns to theaters with Fox Mulder, Dana Scully — and a lot riding on the bet that fans want more of the FBI's paranormal-investigating agents.
The film, which remains without a formal title, will dump the long-running "mythology" plotline — that aliens live among us and are part of a colonizing effort — that made it one of the most popular television shows in the late 1990s but ultimately drove away some viewers who found it too complex and ambiguous.
"We spent a lot of time on (the mythology) and wrapped up a lot of threads" when the show went off the air in 2002, says Chris Carter, creator of the series and director of the new movie. "We want a stand-alone movie, not a mythology conspiracy one."
That will come as welcome news to fans of the show's stand-alone episodes, which included cults, ghosts, psychics and ancient curses.
Carter refuses to divulge any plot points of the movie, but says he wanted to make the film immediately after the show ended. A contractual dispute with 20th Century Fox kept it on the shelf until the case was settled out of court.
He says the delay may turn out to be a blessing.
"There's a whole audience I want to introduce X-Files to," Carter says. "There were kids who couldn't watch it on TV because it was too scary. Now they're in college. I wanted a movie that everyone could go to." http://louis-j-sheehan.net http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us
Whether they will could be a test of the show's legacy, says Blair Butler of the G4TV network, which caters to video-game enthusiasts and science-fiction fans.
"At its strongest, it had really creepy stand-alone episodes," she says. "They turned it into a great franchise. But a lot of years have passed. We'll see if it's fallen off the radar."
She says the film could benefit from an ironic twist: the Writers Guild strike.
"I think it could be a sort comfort food for the people who loved how original the show was and aren't seeing original TV now," she says.
But Carter believes they'll be drawn by something else: the show's stars, David Duchovny and Gillian Anderson.
"For me, The X-Files has always been a romance," he says. "They had an intellectual romance that's very rare and restrained compared to so many relationships on TV. I think that's what appealed most to the fans. And they're back."
http://louis-j-sheehan.net http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us People have been trying to figure out why we sleep for almost as long as we have been conscious of being awake, tossing and turning in the dark.
After a few restless nights, most of us can't even think straight. We are less able to make sense of problems, make competent moral judgments or retain what we learn, even though studies show our brain cells fire more frenetically to overcome the lack of sleep. Lose too much sleep and we become reckless, emotionally fragile, and more vulnerable to infections and to diabetes, heart disease and obesity, recent research suggests.
We spend a third of our lives asleep, yet no one really knows why. We do know that people simply don't perform as well when they don't sleep enough. How sleepy are you? The Epworth Sleepiness Scale can help you rate how likely you are to doze off or fall asleep. The American Academy of Sleep Medicine and the National Sleep Foundation offer general information about sleep and sleep disorders. The National Institute of Neurological Disorders and Stroke also offers a detailed rundown on the basics of sleep. New scientific findings about the biology of sleep are highlighted at Sleep Research Online
Bedside Reading The Society for Neuroscience offers these Brain Briefings on sleep and learning, insomnia and sleep deficits. For bedside reading about sleep, Stanford University researcher William Dement, founder of the world's first sleep disorder clinic, and science writer Christopher Vaughan outline cures for "a sleep-sick society" in The Promise of Sleep: A Pioneer in Sleep Medicine http://louis-j-sheehan.net http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us
Yet scientists probing the purpose of sleep are still largely in the dark. "Why we sleep at all is a strange bastion of the unknown," said sleep psychologist Matthew Walker at the University of California in Berkeley.
One vital function of sleep, researchers argue, may be to help our brains sort, store and consolidate new memories, etching experiences more indelibly into the brain's biochemical archives.
Even a 90-minute nap can significantly improve our ability to master new motor skills and strengthen our memories of what we learn, researchers at the University of Haifa in Israel reported last month in Nature Neuroscience. "Napping is as effective as a night's sleep," said psychologist Sara Mednick at the University of California in San Diego.
Moreover, slumber seems to boost our ability to make sense of new knowledge by allowing the brain to detect connections between things we learn.
In research published last April in the Proceedings of the National Academy of Sciences, Dr. Walker and his collaborators at the Harvard Medical School tested 56 college students and found that their ability to discern the big picture in disparate pieces of information improved measurably after the brain could, during a night's sleep, mull things over.
It is these patterns of meaning -- the distilled essence of knowledge -- that we remember so well. "Sleep helps stabilize memory," said neurologist Jeffrey Ellenbogen, director of the sleep medicine program at Massachusetts General Hospital.
The erratic biorhythms of sleep and behavior are intertwined everywhere in nature. Socially active fruit flies need more sleep than loner flies, and even zebra fish can get insomnia.
Sleep is controlled partly by our genes. The difference between those of us who naturally wake at dawn and night owls who are wide-eyed at midnight may be partly due to variations in a gene named Period3, which affects our biological clock. Variations in that gene also make some people especially sensitive to sleep deprivation, scientists at the U.K.'s University of Surrey recently reported. http://louis1j1sheehan1esquire.us/page1.aspx http://louis1j1sheehan1esquire.us http://louis-j-sheehan.org/page1.aspx
How much sleep do you need? And how much do you actually get? Tell us about your sleep habits in an online forum12.
For many of us, though, sleeplessness is a self-inflicted epidemic in which lifestyle overrides basic biology. "In this odd, Western 24-hour-MTV-fast-food generation we have created, we all feel the need to achieve more and more. The one thing that takes a hit is sleep," Dr. Walker said. On average, most people sleep 75 minutes less each night than people did a century ago, sleep surveys record.
Yet, rarely have so many millions of drowsy people been trying so hard to secure some shut-eye, spending billions on sleep aids. By one estimate, pharmacists filled 49 million prescriptions for sleep drugs last year. Even so, we think we sleep more than we actually do, according to Arizona State University scientists. They recorded how long 2,100 volunteers actually slept each night and compared that with how long the people reported they had slept. Most people overestimated their sleep by about 18 minutes, the scientists found.
Psychologists Jeffrey Ellenbogen at Harvard's Mass General Hospital and Matthew Walker at UC/Berkeley found that sleep boosts our ability to make sense of new knowledge by allowing the brain to detect connections and patterns between things we learn. They reported their findings recently in The Proceedings of the National Acemdy of Sciences.
The consequences of too little sleep can be dire. Almost half of all heavy-truck accidents can be traced to driver fatigue, while decisions leading to the Challenger space-shuttle disaster, the Chernobyl nuclear-reactor meltdown and the Exxon Valdez oil spill can be partly linked to people drained of rest by round-the-clock work schedules. Weary doctors make more serious medical errors, while sleepy airport baggage screeners make more security mistakes, researchers reported at the Associated Professional Sleep Societies.
All told, the frayed tempers, short attention spans and fuzzy thinking caused by sleep deprivation may cost $15 billion a year in reduced productivity, the National Commission on Sleep Disorders Research estimated.
The expectation of a nap, however, is by itself enough to measurably lower our blood pressure, researchers at the Liverpool John Moores University in England reported in October in the Journal of Applied Physiology. http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx
Indeed, regular nappers -- working men who took a siesta for 30 minutes or more at least three times a week -- had a 64% lower risk of heart-related death, researchers at the University of Athens reported last February in the Archives of Internal Medicine.
"All of the things we are proving about sleep and the brain are things that your mother already knew decades ago," Dr. Walker said. "We are putting the science and the hard facts behind it."
Scientists have taken a key step toward understanding the cause of prostate cancer, finding that a combination of five gene variants sharply raises the risk of the disease. Added to family history, they accounted for nearly half of all cases in a study of Swedish men.
The discovery is remarkable not just for the big portion of cases it might explain, but also because this relatively new approach -- looking at combos rather than single genes -- may help solve the mystery of many complex diseases.
It also might lead to a blood test to predict who is likely to develop prostate cancer. These men could be closely monitored and perhaps offered hormone-blocking drugs like finasteride to try to prevent the disease.
The Swedish results must be verified in other countries and races, where the gene variants, or markers, may not be as common. Researchers already have plans to look for them in U.S. men. Unfortunately, the markers do not help doctors tell which cancers need treatment and which do not -- they turned out to have nothing to do with the aggressiveness of a tumor, only whether a man is likely to develop one.

The study was led by doctors at Wake Forest University in Winston-Salem, N.C., and involved Johns Hopkins University in Baltimore and the Karolinska Institute in Stockholm. Results were published online by the New England Journal of Medicine.
It involved 2,893 men with prostate cancer and 1,781 similar men who did not have the disease. Sweden was chosen because the population is so ethnically similar and well suited to gene studies.

A new and hitherto unknown atmospheric gas, a combination of oxygen and nitrogen, exists 10 to 25 miles above the Earth's surface, Drs. Arthur Adel and C.O. Lampland of the Lowell Observatory, Flagstaff, Ariz., announced to the American Association for the Advancement of Science at the Indianapolis meeting.
It is nitrogen pentoxide, its molecule consisting of two atoms of nitrogen and five of oxygen. It is probably the rarest of gases of the air, present only in the outer regions where the ultraviolet rays of the sunlight bring oxygen and nitrogen into combination.
Existence of the new gas in the ozone layer of the atmosphere was demonstrated by delicate spectroscopy of the far infrared region of the spectrum. If the new gas existed nearer to Earth in the air around us, it would not be detectable by the most refined chemical and physical methods. Because the nitrogen pentoxide takes out certain portions of the sunlight as it comes through the atmosphere to Earth, its existence could be detected.
The situation of Lowell Observatory high on a mountain in a dry atmosphere contributed to the discovery. http://louis-j-sheehan.net http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx http://louis-j-sheehan.info http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us http://louis-j-sheehan.org http://louis1j1sheehan1esquire.us/page1.aspx http://louis1j1sheehan1esquire.us http://louis-j-sheehan.org/page1.aspx http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx http://louis-j-sheehan.biz/page1.aspx http://louis-j-sheehan.biz http://louis-j-sheehan.biz/
What use was there for a ball-and-socket jointed bone at the back of a dinosaur's skull?
Charles W. Gilmore, curator of vertebrate paleontology at the U.S. National Museum, would like to know.
At the back of the skull of a hadrosaur, a rooster-crested monster that once lived in Montana, he has found a bone arrangement that has never been found in any other kind of skull. A relatively small, triangular bone bears on its front edge a socket or cup, which fits neatly over a ball-shaped projection on the bone in front of it.
Whatever was the use of this unique skull-joint, it could hardly have been to make room for the hadrosaur's massive brain. For the hadrosaur's brain was anything but massive. It couldn't have weighed more than 2 or 3 ounces. It was enough to see, hear, and probably smell with, but that was about all. But then, very likely a dinosaur never bothered to think—except possibly once in a while about another dinosaur.
1) The bigger the telescope the better, right? So what if your scope is the size of the Earth? A technique called interferometry combines the light from telescopes that are widely separated, and with it you can make a virtual telescope that’s the same size as the distance between the physical telescopes. If those ’scopes are on opposite sides of the Earth, you get a telescope thousands of miles across. Using this technique, astronomers have made phenomenal measurements, including actually seeing the rotation of the galaxy M33 as well as its physical motion across the sky; something that had never been done before. They have been able to see the effects of the Sun’s motion around the Milky Way’s center, even though a full orbit takes 240 million years!
2) One long-standing mystery in astronomy is an apparent fountain of antimatter streaming out from the center of the Galaxy. What’s causing it? Most astronomers assumed it was coming from the giant supermassive black hole there, but now observations indicate it’s actually being accelerated by binary stars, where one of the two orbiting stars is a neutron star or black hole. The cloud of antimatter is detected because it gives off gamma rays, which are a very high energy form of light. The gamma rays from the Galactic center are not centered on the center (hmmm, remember to edit that line), but extend a little bit more on the western side. This matches the distribution of the black hole or neutron star binaries. These binaries can generate antimatter when regular matter from the normal (sunlike) star swirls around the denser object. http://louis-j-sheehan.net http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx http://louis-j-sheehan.info http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us http://louis-j-sheehan.org http://louis1j1sheehan1esquire.us/page1.aspx http://louis1j1sheehan1esquire.us http://louis-j-sheehan.org/page1.aspx http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx http://louis-j-sheehan.biz/page1.aspx http://louis-j-sheehan.biz http://louis-j-sheehan.biz/
3) The most luminous objects in the Universe are, ironically and paradoxically, the faintest. Huh?
Black holes can generate fantastic amounts of light as matter falling in to the hole first forms a disk around it. The disk is hot, and magnetic forces (along with friction and gravity) can make it extremely bright, as bright as billions of stars like the Sun. Supermassive black holes in the centers of galaxies are big, and have proportionately big disks which can outshine the rest of the galaxy in which it sits. We call these active galaxies, and there are different kinds (quasars, blazars, Seyferts) depending on the various characteristics of the galaxy. It turns out, though, that in many cases our view of these black holes is blocked by tick gas and dust in the galaxy. The folks at the Sloan Digital Sky Survey have figured out a way to detect a fingerprint of these obscured galaxies, and found 887 hidden quasars that were previously unknown, by far the largest such sample ever made. What this means is that we have to be careful in the future about what objects we can and cannot see — astronomers may say "We expect to see XXX of these kind of galaxies and see none, which means our cosmology is wrong," we can take it with a judicious grain of salt.
Space is a dangerous place. Stars explode, black holes gobble up matter… but some violent events are so huge they affect entire galaxies, mayhem on a scale so vast it numbs the mind. Galaxies are island universes, cities of billions or even hundreds of billions of stars. Some galaxies, like our Milky Way, live pretty much on their own, but others live in vast complexes called clusters. These galaxy clusters may have hundreds or thousands of denizens, all orbiting each other due to their mutual gravity, looking something like bees buzzing around hive. But there is more there than just the matter we see. Dark matter is there as well; invisible stuff that adds to the gravity of the cluster due to its mass, but gives off no light. However, it betrays its presence in two ways: its gravity changes the motion of the galaxies in the cluster, and it distorts the light from more distant galaxies due to gravitational lensing. http://louis-j-sheehan.net http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx http://louis-j-sheehan.info http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us http://louis-j-sheehan.org http://louis1j1sheehan1esquire.us/page1.aspx http://louis1j1sheehan1esquire.us http://louis-j-sheehan.org/page1.aspx http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx http://louis-j-sheehan.biz/page1.aspx http://louis-j-sheehan.biz http://louis-j-sheehan.biz/
A team of astronomers has used the Hubble Space Telescope to examine the galaxy cluster Abell 901/902 (they call their project STAGES: Space Telescope A901/902 Galaxy Evolution Survey). They wanted to very carefully map out many aspects of the cluster: how many galaxies it contains, what kinds of galaxies they are (spirals, ellipticals, etc.), and, using lensing, determine where the dark matter is. By making a map of all of these characteristics, they hoped to be able to understand the history of the cluster, since the present configuration of the cluster can provide clues to its past. For the first time, these cosmic archaeologists were able to map out the dark matter of this cluster, and found four very large concentrations of it scattered throughout Abell 901/902. These clumps of invisible stuff are enormous: they total a stunning 100 trillion times the Sun’s mass, or 500 times the mass of our entire galaxy. Needless to say, that much mass exerts a powerful gravitational pull. Galaxies round the clumps are falling in toward them, inexorably drawn in by the clumps’ gravity. And as they fall in from the suburbs to the downtown regions, they change. They slam into the thin gas between galaxies, which can blow out the gas inside the galaxies (like leaving you car window open on a highway can air out the inside of the car), for one. But as the galaxies fall in, the inevitably interact with one another, colliding and merging as the make the downhill slide. This distorts the galaxies’ shapes, and that in turn allows the astronomers to determine the past history of the objects. What’s interesting is that they found that galaxies tend to be more distorted on their way in to the centers of the clusters than they are when they are actually at the center. It appears that as they fall, they have time to interact and merge, changing their shape, but once they aproach the center they are falling so quickly they simply don’t have time to distort much as they pass each. Also, it takes time to settle in at the center, so the galaxies at the center appear to be very old, and have finished their transformation from being unsettled and twisted into more sedate, round, elliptical galaxies. The astronomers also determined that the galaxies at the edge of the cluster still produce stars, but by the time they reach the center that has mostly turned off. Their gas — needed to make stars — gets blown out of the galaxies on the way in, and the mergers trigger vast bursts of star formation, which also uses up the gas. These discoveries were possible only through the use of Hubble, Spitzer, and other telescopes, each of which unpeeled another layer of the puzzle. I’ll note that for Hubble’s part, this represents the largest area of sky ever observed by the grand dame of space ’scopes; it took 80 separate pointings of Hubble to complete the survey of the cluster, and they mapped the locations and shape of 60,000 galaxies in all, a truly staggering amount. One last thought: the Milky Way is more or less alone in space, being part of a loose collection of other galaxies. But we are headed toward the Andromeda galaxy, and in a couple of billion years we’ll collide and merge with it. I hope that in this far flung future, some distant astronomers can use our own violent fate to learn a little more about the Universe, too. It only seems fair. http://louis-j-sheehan.net http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx http://louis-j-sheehan.info http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us http://louis-j-sheehan.org http://louis1j1sheehan1esquire.us/page1.aspx http://louis1j1sheehan1esquire.us http://louis-j-sheehan.org/page1.aspx http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx http://louis-j-sheehan.biz/page1.aspx http://louis-j-sheehan.biz http://louis-j-sheehan.biz/
One of the more amazing aspects of looking into deep, deep space is that the path there is tortured and twisted. Space itself can be distorted by mass; it gets bent, like a road curves as it goes around a hill. And like a truck that must follow that road and steer around the hill, a photon must follow the curve of space. Imagine a distant galaxy, billions of light years away. It emits light in all directions. One particular photon happens to be emitted almost — but not quite — in our direction. Left on its own, we’d never see it because it would miss the Earth by thousands or millions of light years. But on its travels, it passes by another massive galaxy. This galaxy warps space, and the photon does what it must do: it follows that curve in pace, and changes direction… and it just so happens that the curve is just right to send it our way. The intervening galaxy is essentially acting like a lens, bending the light. If the more distant galaxy is exactly behind the lensing galaxy, we see the light from that more distant galaxy distorted into a perfect ring, a circle of light surrounding the lens. We call this an Einstein Ring. If the farther galaxy is off to the side a bit, we see an arc instead of a complete ring. Gravitationally lensed arcs and rings are seen all over the sky, and they can be used to determine the mass of the intervening galaxy! The more mass, the more distorted the light from the farther galaxy. So the Universe has given us a nice method to let us weigh it. In a surprising twist, astronomers have found a new type of lensed galaxy: a double ring! In a rare alignment, there are two distant galaxies aligned behind an intervening lensing galaxy. They’re like beads on a wire, lined up just right such that both more distant galaxies are lensed by the nearer one. In this case, the lens is about 3 billion light years away, and the other two are 6 and 11 billion light years away, an incredible distance. This image is amazing, but it is also a powerful scientific tool. It allows us to measure not just the mass of the lensing galaxy, but also the amount of mysterious dark matter nearby. We cannot see the dark matter, but it too bends light, and contributes to the lensings. By observing lenses like this, we can take a sample of dark matter in the Universe, and that’s a crucial first step in understanding it. Even better, these double rings allows us to measure the amount of total mass not just in the nearest galaxy, as is usual, but also in the middle galaxy as well, since it distorts the light from the galaxy behind it (turns out it’s a rather lightweight one billion solar masses; our own Galaxy has more than 100 times that mass, so the middle galaxy is considered a dwarf). http://louis-j-sheehan.net http://louis-j-sheehan.net/page1.aspx http://louis-j-sheehan.info/page1.aspx http://louis-j-sheehan.info http://louis-j-sheehan-esquire.us/page1.aspx http://louis-j-sheehan-esquire.us http://louis-j-sheehan.org http://louis1j1sheehan1esquire.us/page1.aspx http://louis1j1sheehan1esquire.us http://louis-j-sheehan.org/page1.aspx http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx http://louis-j-sheehan.biz/page1.aspx http://louis-j-sheehan.biz http://louis-j-sheehan.biz/
This is a beautiful happenstance; it gives us a measure of the Universe at two points, with one being for free. In fact, Tommaso Treu, the astronomer at U.C. Santa Barbara who investigated this lens, points out that if we can find as few as 50 of these double rings, we can get a much better idea of the distribution of not just dark matter, but also the even more mysterious dark energy in the Universe. That’s one of the biggest goals of modern astronomy… and we may get a handle on it due to a coincidental ring toss.

Space is a dangerous place. Stars explode, black holes gobble up matter… but some violent events are so huge they affect entire galaxies, mayhem on a scale so vast it numbs the mind. Galaxies are island universes, cities of billions or even hundreds of billions of stars. Some galaxies, like our Milky Way, live pretty much on their own, but others live in vast complexes called clusters. These galaxy clusters may have hundreds or thousands of denizens, all orbiting each other due to their mutual gravity, looking something like bees buzzing around hive. But there is more there than just the matter we see. Dark matter is there as well; invisible stuff that adds to the gravity of the cluster due to its mass, but gives off no light.

SURGICAL PROCEDURE:
Laparoscopic cholecystectomy.
PREOP DIAGNOSIS:
Signs and symptoms included:
Digestive disturbances Tenderness on pressure over gallbladder Pain to back and right shoulder
Pathology: suffering from stones.
Diagnosis: Symptomatic non-acute cholelithiasis.
• Patients are fasted for approximately 8 hours before elective operations.
• Routine administration of intravenous antibiotics for prophylaxis against wound infections is not mandatory in uncomplicated cases of cholelithiases.
• Prior to induction of anesthesia, deep venous thrombosis prophylaxis should be utilized.
[Bib: A page 192.]
POSTOP DIAGNOSIS:
Symptomatic non-acute cholelithiasis.
Although major complications are rare, cardiopulmonary complications may occur as is the case in any major abdominal operation. Additionally, other rare possible complications include:
Bile duct injury Bile leaks Biliary stricture Hemorrhage Perforated bladder Retained stones Pancreatitis Wound infections Incisional hernia Duodenal injury Hepatic Artery injury Damage to structure of Porta Hepatis Atelectasis
[Bib: A page 189.]
Assuming there are no complications, postoperative care consists of:
• Clear liquids are resumed postoperatively and the patient progresses to a regular diet as tolerated.
• No activity or work restrictions are placed on the patient depending upon the degree of abdominal tenderness; the patient is encouraged to return to work within one week.
• Nausea and mild shoulder discomfort from diaphragmatic irritation may occur in the early postoperative period.
[Bib: A page 192.] PREOP DIAGNOSTIC STUDIES:
History and physical.
Simple cholelithiasis resulting from obstruction of the infundibulum of the gallbladder or the cystic duct does not normally result in laboratory abnormalities. Serum bilirubin is usually normal unless there is a concomitant obstruction of the common bile duct.
Plain radiographs of the abdomen are rarely useful in diagnosing cholelithiasis.
Transcutaneous ultrasound of the upper right quadrant should be the diagnostic tool of choice in patients with suspected biliary pathology. Ultrasound is 95% sensitive and 98% specific in detecting gallstones and may demonstrate thickness of the gallbladder wall, pericholecystic fluid collections, choledococolothiasis, sludge, polyps, microcalcifications, and the diameter of the common bile duct. Additionally, the physician may also evaluate the right kidney, liver and pancreas. It should be noted that computed tomography (CT) is not as useful in evaluating biliary disease as is ultrasound.
[Bib: A page 183.]
TYPE OF ANESTHESIA:
The operation is performed under general anesthesia.
After induction of anesthesia, a urinary bladder catheter and a naso/orogastiric tube are generally placed to decompress these hollow organs

POSITIONING
PATIENT POSITIONING:
Supine. Arm on armboard.
OR BED POSITION:
The table was initially placed in Trendelenburg between 5 and 10 degrees to facilitate the establishment of the C02-pneumoperitineum. Then the patient was positioned in a 30 to 40 degree Reverse Trendelenburg and was further rotated to the left by 15 – 20 degrees. These movements/repositionings allowed the colon and duodenum to fall away from the liver’s edge and the falciform ligament and the liver (both lobes) to be examined. The inferior margin of the liver was also more easily visualized so as to locate the gallbladder. In most surgeries the gallbladder is visible beyond the edge of the liver but, sometimes, the gallbladder can only be seen after adhesions are removed and/or after elevating the liver.
[Bib: B page 90.]
POSITIONING SUPPLIES AND EQUIPMENT:
Adjustable OR bed Armboards Footstool
[PIC Sheet]
DRAPPING PROCEDURE:
Squared off towels around the abdomen. Laparotomy drape /sheet with tape removed.
[Bib: D page 76.]
DESCRIBE SURGICAL PROCEDURE: (IF AN ORGAN(S) WAS/WERE REMOVED, WHAT STRUCTURES WERE LIGATED TO REMOVE THE ORGAN(S)?) (WHAT INSTRUMENTS WERE USED?) (COUNTS?)
ANATOMY:
See attached drawings.
[Bib: E pages 12 – 39.]
COUNTS:
1. When all items open on backtable and before mayo set-up. 2. Closing 1: at closing of peritoneum/first layer of cavity. 3. Closing 2: at closure of fascia. 4. Closing 3: initiation of skin closure.
Port Placement - CO2-pneumoperitineum 10 mm Trocar
A CO2-pneumoperitineum was created to facilitate safe placement of trocars into the abdomen; 15 mmHg is a conventional benchmark. The CO2-pneumoperitineum can be created using either an open or closed technique. If hemodynamic compromise were to develop, the CO2-pneumoperitineum would be emptied until vital signs return to normal.
At the infraumbilical skin fold an incision of approximately 1.5 cm horizontally was made to place the CO2-pneumoperitineum port.
Next, the retroperitoneum posterior to the umbilicus and the pelvis were viewed to ensure there was no injury resulting form the trocar/sheath with a 10 mm laparoscope/camera. While there, the pelvic viscera, anterior surface of the intestines, omentum and stomach were visualized and no abnormalities were noted.
Two 5 mm Subcostal Ports
The surgeon next placed two 5mm subcostal ports in the upper right quadrant.
The first port was placed in the anterior-to middle axillary line between the 12th rib and the iliac crest inferior to the gallbladder fundus/liver edge.
The second 5 mm port was placed midway between he axillary sheath and the xiphoid process.
These two ports allowed the use of grasping forceps to retain/secure the gallbladder. The lateral grasping forceps were used to elevate the liver’s edge to clearly expose the fundus of the gallbladder. The dissecting forceps were then used to raise the most dependent portion of the fundus. The grasping forceps were then used to push laterally and cephaladly to roll up the entire right lobe of the liver so as to expose the porta hepatis and the gallbladder. Adhesions in this area are generally avascular and were lysed bluntly with dissecting forceps by slowly stripping them in the direction of the infundibulum; any vascular adhesions would be lysed with the hook cautery.
After the infundibulum was exposed, grasping forceps were placed through the midclavicular trocar for traction on the neck of the bladder.
The Second 10 mm Trocar
The last trocar was placed through a longitudinal incision in the midline of the epigastrium near the location of the gallbladder (the size of the left liver lobe can also influence placement). This trocar was angled to the right of the falciform ligament aiming toward the gallbladder.
Exposure
The fundus was now retracted superiorly to the infundibulum. The gallbladder was placed under tension and away from the common bile duct in the inferolateral direction. With the fundus and neck of the gallbladder under tension, a fine-tipped dissecting forcep was used to gently pull away the overlying fibroareolar structures from the gallbladder infundibulum and Hartmann’s pouch starting on the gallbladder and pulling the tissue toward the porta hepatis.

Dissection
The peritoneum was lysed. The hepatocystic triangle (a.k.a. Calot’s triangle) was placed under tension and exposed by retracting the gallbladder infundibulum inferiorly and laterally while pushing the fundus superiorly and medially. Often there is a lymph node overlying the cystic artery which, if there, is removed; if so, electrical current is used to achieve hemostasis.
The infundibulum of the gallbladder was stretched superiorly and medially even as the fundus was pushed superiorly and laterally to expose the reverse of the hepatocystic triangle (the area between the cystic duct, the common hepatic duct, and the right lobe of the liver). It was critical to precisely locate the junction between the infundibulum and the origin of the cystic duct. The tip of the hooked-shaped cautery was used to probe and expose the duct. The cystic artery is often separated from the surrounding tissue now (but can be separated later depending upon the individual’s anatomy). The cystic duct was now dissected as it was anteriorly in the field.
Cholangiography
Some surgeons now perform a static or fluoroscopic cholangiography for evaluation of the stones at this juncture. (I did not see any of this.)
Cystic Duct
The Cystic duct was then doubly clipped near its junction with the common bile duct and then was divided. Care was taken to avoid injuring surrounding structures with the clips. Great care was taken to avoid clipping the common bile duct; if this were to prove to be too risky, a loop or suture would have been used instead of clips.
Cystic Artery
The infundibulum of the gallbladder was placed under tension and the cystic duct was bluntly dissected, then clipped proximally and distally and divided by sharp dissection. Care was taken to not confuse the right hepatic artery with the cystic artery.
The ligations of the duct and cystic artery were examined to confirm that neither bile nor blood is leaking, that the clips are secure, and that the clips close the entire lumen without attaching any of the adjacent tissue. Irrigation and suctioning were used to remove debris. The grasping forceps in the midclavicular trocar were repositioned on the proximal end of the gallbladder at Hartman’s pouch. The infundibulum was retracted superiorly and laterally and also away from its hepatic bed. The tissues that tethered the neck of the gallbladder were inspected to ensure no other sizeable tubular structures were in this immediate area. The hepatic fossa was divided and coagulated (both small vessels and lymphatics were coagulated). On rare occasion, a blood vessel or small duct will require the placement of another clip.
Gallbladder Dissection
As necessary, any tears in the gallbladder wall may be clipped or looped to prevent stone leakage or additional bile leak.
As always (i) the hepatic fossa and porta hepatis were monitored for any blood and/or bile leakage, (ii) the clips were monitored for stability, and (iii) small bleeding points were coagulated with electrocautery, and (iv) the liver was examined for hemostasis. Further, irrigation assists with the visualization at this juncture.
The gallbladder was then separated with electrocautery. With the tissue connecting the gallbladder to the fossa placed under tension, the surgeon used electrocautery (typically the hook) set at 25 (sometimes 30) to divide and coagulate the tissue.
The dissection of the gallbladder continued from the infundibulum to the fundus with intermittent repositioning of the midclavicular grasping forceps proximal to the plane of dissection to allow maximal contraction until the gallbladder was attached only by a narrow and thin tissue.
Finally, the little remaining attachments to the gallbladder were lysed.
Removal
The laparoscope was transferred to the midepigastric port.
The gallbladder was removed via the umbilicus under direct visualization from the laparoscope. The umbilical port was used because there are no thick muscle layers at this point and there is only one fascial plane that must be crossed. Additionally, if an incision needs to be enlarged because of the size of the stones, extending the umbilical incision causes less postoperative pain than does extending any of the other incisions.
At Harrisburg, I have always seen the use of an entrapment bag. The grasper forceps were used to place the gallbladder into the entrapment sack. The gallbladder-containing entrapment sack was then withdrawn through the umbilical port. This left the neck of the gallbladder on the anterior abdominal wall and the distended fundus within the abdominal cavity.
If the gallbladder were to be enlarged due to stones or bile, a suction catheter could have been used for aspiration before the entrapment sack’s withdrawal. As an alternative, stone forceps could have been placed into the gallbladder to extract or crush overly large stones. Rarely, the incision must be enlarged to remove larger stones.
The gallbladder was a specimen.

The holidays are over. Resolutions are wearing thin. It's a time of year when many people wonder if they have a drinking problem.
More than 30% of Americans engage in risky drinking at some point in their lives, according to the National Institute on Alcohol Abuse and Alcoholism. But there's no consensus on exactly what an "alcoholic" is. Even Alcoholics Anonymous relies on alcoholics to diagnose themselves.
Researchers have made up dozens of screening tests over the years. According to one developed for Johns Hopkins University Hospital years ago that still pops up on the Web, I'm "definitely an alcoholic" because I answered yes to at least three of 20 questions: I "crave a drink at a definite time of day" (evenings, mostly) and drink alone (sometimes) and drink to "escape from worries or troubles" (doesn't everyone who drinks?).
But Alcoholscreening.org3 says I'm "below the range usually associated with harmful drinking or alcoholism" since I have only a glass or two of wine when I drink.
The authoritative American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, or DSM-IV, separates alcohol abuse from alcohol dependence, based partly on the problems the drinking causes. You qualify for a diagnosis of "abuse" if you've done any one of these in the past year: drunk alcohol in hazardous situations, like driving; kept drinking despite social or interpersonal problems; had legal problems related to alcohol or failed to fulfill major obligations at work, school or home because of drinking.
You've moved on to "dependence" if you've done any three of these seven: drunk more or longer than you intended; been unable to cut down or stop; needed more alcohol to get the same affect; had withdrawal symptoms without it; spent more time drinking or recovering; neglected other activities or continued to drink despite psychological or physical problems.
Experts long believed that abuse progressed to dependence, which almost inevitably became chronic and relapsing -- but that was based on observing severely addicted people in treatment programs. Several large new surveys have shown that drinking patterns in the general population are much more varied, with milder forms of dependence. Some 43% of daily heavy drinkers don't fit into either DSM-IV category, according to one big national sample, even though they are setting themselves up for serious health and addiction problems.
Abuse vs. Dependence http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx http://louis-j-sheehan.biz/page1.aspx http://louis-j-sheehan.biz http://louis-j-sheehan.biz/
http://louis-j-sheehan.de/page1.aspx http://louis-j-sheehan.de/ http://louis1j1sheehan1esquire.blogspot.com/
"Some people will abuse alcohol -- driving drunk, for example -- but they only drink heavily once a month. They can remain stable for a long time and not progress to dependence," says Mark L. Willenbring, director of the division of treatment and recovery research at the NIAAA. "And people can be dependent and not have abuse problems at all. They're successful students. They're good parents, good workers. They watch their weight. They go the gym. Then they go home and have four martinis or two bottles of wine. Are they alcoholics? You bet. And the goal is to get treatment for these folks, earlier, that is acceptable and attractive and effective."
To that end, some experts want the DSM-V -- the new edition now being compiled -- to combine abuse and dependence into a single "alcohol-use disorder" that ranges in severity, taking into account harmful drinking patterns and other symptoms. The aim is for simmering problems to be spotted sooner.
As one former treatment counselor says, "The conventional wisdom held that alcoholics had to hit bottom before they could get better. We'd like to raise that bottom so that people don't have to fall as far before they get help." [Health]
Many heavy drinkers are very high-functioning -- until they can't function anymore. "Alcoholics can be high achievers in the short run, because they're driven and compulsive," says Charlie, a New York attorney who, like all AA members, wants to remain anonymous. Charlie was drinking about a fifth of Johnnie Walker most nights when it began to show. "I'd tell my secretary I was in a meeting with a client, but I'd be home and only starting to feel human by about noon. Then I'd try to do eight hours of work in four hours," he says. This went on for seven years, until he finally went into rehab. He's been sober now for 26 years.
Charlie says many heavy drinkers, especially those who grew up around alcoholics, set a private benchmark in their denial. "They say to themselves, 'As long as I'm not making a fool of myself in a bar, or drinking in the morning, or as long as I'm still showing up for work, then I'm not an alcoholic.'"
You know you've hit bottom, he adds, "when your behavior spirals downward faster than you can lower your standards."
Thinking You're Immune
Ruth, a nursing supervisor in Las Vegas, hid her quart-a-day whiskey habit from work for about five years -- "until my husband and my employer both invited me out of those positions at the same time," she says. "That got my attention."
Both of Ruth's parents died of alcohol-related illnesses, but she thought her medical training would protect her from getting seriously addicted. Doctors and clergy who drink heavily often have the notion that they are somehow immune to the problems they see in others, she observes, and affluent people can pay others to take care of them. "People with less money and less education often get the message faster," she says, now that she's been sober for 37 years.
NIAAA officials say that in recognizing a drinking problem, the label "alcoholic" is less important than harmful patterns of drinking, which they describe as drinking too much, too fast or too much, too often.
Too much, too fast means consuming more than four drinks in two hours for men, and more than three in two hours for women. That's a level that, on average, makes people legally drunk and impairs brain function. (A standard U.S. drink, by the way, is 12 oz. of beer, 5 oz. of wine or a 1.5 oz. shot of 80 proof spirits, according to government agencies.)
Even if you stay within those limits each day, you can be drinking too much, too often, if you have more than 14 drinks a week for men, and more than 7 for women. That's the kind of chronic use that raises the risks of a long list of health problems, including liver and cardiovascular disease, pancreatitis, dementia, depression and numerous cancers.
How those weekly drinks are distributed is also important. "If you drink seven drinks in two days, that's hazardous -- you're drunk two days a week," says Ting-Kai Li, the NIAAA's director. "If you drink two a day for seven days, that's not harmful. In fact, it may even be beneficial for some people, lowering their cardiovascular risk."
Individual responses to alcohol vary, of course, based on genetics, brain chemistry, metabolism and other factors. Your risk is already elevated if you have a family history of alcohol abuse, have health problems such as depression, take certain medications or you started drinking at an early age. "If you have a family history or other co-morbidity, then the general advice is, don't drink at all," says Dr. Li.
If you're worried that you may be drinking too much, you've already met a key criterion on some screening tests. (Like the old saying about mice in your house, if you think you have a problem, you probably do.)
Counting drinks very carefully to stay within the limit can be a sign of trouble too, says Ruth. "The glass keeps getting bigger and bigger or you forget to add the mixer." She suggests trying to go 30 or 60 days without drinking. "If it doesn't bother you, you're OK. But if you're desperate for that 30 days to end, or you can't make it, then get help." She suggests trying one of AA's public information meetings. "If you're not an alcoholic, you can't catch it from them," she says.
Your family doctor is another place to start. The NIAAA recently issued a guide for primary-care physicians (www.niaaa.nih.gov/guide4) to enlist their help in spotting alcohol problems. It starts with a single screening question: How many times in the last year have you had more than five drinks (four for women) in a day? If the answer is even once, doctors are advised to discuss the risks of harmful drinking with their patients, along with steps patients can take to cut back, including new medications that can help curb alcohol cravings. http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx http://louis-j-sheehan.biz/page1.aspx http://louis-j-sheehan.biz http://louis-j-sheehan.biz/
http://louis-j-sheehan.de/page1.aspx http://louis-j-sheehan.de/
In Remission
The encouraging news from the NIAAA's recent research is that many people do cut down or quit on their own. "That's the real mind blower," says Dr. Willenbring. "Only about 15% of the people who develop alcohol dependence in their lifetime have the severe, relapsing form. Most people -- 72% -- have a single episode [of addiction] lasting on average three or four years and then they go into remission and stay there. A lot of them are abstaining." For many people, that spate of heavy drinking happens in college -- the peak years are 18 to 24, says Dr. Willenbring. "Then they mature out of it and get on with their lives."
For those who don't, alcoholism, however it's defined, is still a profound problem, and the third leading cause of preventable death in the U.S., after smoking and obesity. But being aware of your risks and cutting down now if you need to may prevent you from becoming one of those statistics.

It’s probably the happiest root canal ever: Molecular archaeologists reported last January that they had drilled into a 10,300-year-old human tooth discovered in Alaska and extracted genetic gold. The molar, recovered from skeletal remains found in 1996 in On Your Knees Cave, located on Prince of Wales Island off southern Alaska, holds the oldest genetic sample ever recovered in the Americas. That sample supports the theory that humans first arrived here about 15,000 years ago and then migrated down the continent’s western coastline.
Brian Kemp, a molecular anthropologist at Washington State University who led the study, found that out of 3,500 Native Americans examined from a genetic database, 1.5 percent showed the same genetic pattern in their mitochondrial DNA as that found in the ancient tooth. “What’s interesting is that the distribution is almost entirely down the west coast of the Americas, all the way down to Tierra del Fuego,” says Kemp. That, says Theodore –Schurr, an anthropologist at the University of Pennsylvania, “lends credence to the reemerging hypothesis that the first modern human populations to arrive in North America and then populate the rest of the Americas used a coastal route to actually get there.”
Kemp also compared the ancient DNA with its related modern DNA to see how fast it mutated over time. This “molecular clock” of mutation rates can be used to calculate when the ancestors of today’s Native Americans first arrived on these shores. Previous estimates pegged their appearance as far back as 40,000 years ago, but Kemp’s newly calibrated clock speeds up the scenario. “Within the last 15,000 years is my bet,” he says.
In the traditional view of photosynthesis, the energy carried by photons streaming from the sun is transferred by bouncing from one chlorophyll molecule to the next, a process that ultimately builds simple carbohydrates from water and carbon dioxide. But last spring, a team led by Graham Fleming, deputy director of the Lawrence Berkeley National Laboratory, reported that the process is much more interesting than that.
Using ultrafast lasers, they found that the interaction between the sun’s energy and the chlorophyll molecules in a bacterium relies on a piece of quantum mechanical weirdness known as superposition, where a single photon’s energy can temporarily be in many different states at once. This allows photosynthesis to probe all the possible reaction pathways within the various chlorophyll molecules. The most efficient pathway is selected and energy is transferred through the bacterium as the superposition collapses.
“This is similar to quantum computing in some sense,” says Greg Engel, a member of Fleming’s team. “This is how quantum computing realizes its incredible efficiency and its ability to solve very complex problems, because it can evaluate many solutions at once.” http://louis-j-sheehan.com http://louis-j-sheehan.com/ http://louis-j-sheehan.com/page1.aspx http://louis-j-sheehan.biz/page1.aspx http://louis-j-sheehan.biz http://louis-j-sheehan.biz/
It may seem like simple compassion to give the terminally ill access to experimental drugs not yet approved by the FDA, but some argue it may also jeopardize the effectiveness of clinical trials and leave patients open to exploitation. In August, the U.S. Court of Appeals for the District of Columbia upheld (pdf) the power of the FDA to control patients’ access to unapproved drugs. The court stated that patients do not have a fundamental right to drugs that have not been proven safe.
The Abigail Alliance for Better Access to Developmental Drugs and the Washington Legal Foundation had filed the suit against the FDA. “What we argue in our lawsuit is that the decision should be a patient’s with their doctor,” says Frank Burroughs of the Abigail Alliance. He founded the organization in 2001 after his 21-year-old daughter Abigail died from head and neck cancer. She had been denied access to the experimental drug Erbitux, which was later approved by the FDA. Burroughs says the groups are planning an appeal to the U.S. Supreme Court.
Many legal experts and ethicists argue that access to unapproved drugs would undermine the scientific process that determines which drugs are effective as well as the FDA’s ability to determine drug safety. Only 8 percent of cancer drugs that enter clinical trials earn FDA approval. The bulk are rejected as ineffective or unsafe. “The very, very sick are open to exploitation,” says Arthur Caplan, chairman of medical ethics at the University of Pennsylvania. He also notes that patients may not join clinical trials if they can get the drugs otherwise, which could impair the development of new drugs.
“I think the court got it right,” says Peter Jacobson of the –University of Michigan School of Public Health. Jacobson views the FDA’s efforts to extend the compassionate use policy as the better way to handle the issue. “Then you’re able to distribute some of these drugs under some kind of scientific protocol without compromising clinical trials that are needed for long-term –understanding.” http://louisjsheehan.blogspot.com/ http://louis9j9sheehan.blogspot.com/ http://louis7j7sheehan.blogspot.com/ http://louis6j6sheehan.blogspot.com/ http://louis5j5sheehan.blogspot.com/ http://louis4j4sheehan.blogspot.com/ http://louis2j2sheehan.blogspot.com/ http://louis1j1sheehan.blogspot.com/ http://louis0j0sheehan.blogspot.com/ http://louis3j3sheehan3.blogspot.com/ http://louis8j8sheehan8.blogspot.com/

The CDC's vaccine advisory panel voted to make shingles vaccination routine for all Americans 60 and older.
Shingles is a painful disease caused by reactivation of dormant varicella zoster virus, or VZV. Best known as the virus that causes chickenpoxchickenpox, VZV is a herpesherpes virus that can come back with a vengeance when a person's immunity wanes with age, disease, or immunity-suppressing drugs.
Without vaccination, about 20% of people who have had chickenpox eventually will get shingles. A person who lives to be 85 has a 50% chance of getting shingles.
Shingles is a bad enough disease to be a good reason to get vaccinated.
But in about a third of cases, shingles turns into an excruciatingly painful disease called postherpetic neuralgia, or PHN. A smaller percentage will get a painful, blinding disease called ophthalmic zoster.
The new vaccine, Merck's Zostavax, won FDA approval last May.
Now the main U.S. vaccine advisory panel -- the Advisory Committee on Immunization Practices (ACIP) -- officially recommends routine use of the vaccine for everyone 60 and older.
The committee voted not to make shingles vaccination routine for people under 60, citing a lack of clinical data on vaccination in that age group.
Similarly, the panel said there was too little data for it to recommend that doctors offer the vaccine for people about to undergo immunity-suppressing treatments. Good Vaccine, Terrible Disease
A major clinical trial shows the vaccine is more than 60% effective in reducing shingles symptoms. Perhaps most importantly, it reduces painful PHN by at least two-thirds.
"Reducing PHN is the motivation for most of us working on this clinical trial," Michael N. Oxman, MD, of the University of California, San Diego, said in a presentation to the ACIP. "For people with severe PHN, their lives are blighted and the lives of their families are blighted."
PHN pain can last for years. Sudden, lancing pain can quite literally bring patients to their knees. Each year, there are more suicides due to PHN pain than due to cancercancer pain.
And PHN isn't the only bad complication of shingles. Some 15% of shingles patients get ophthalmic zoster -- shingles that affects one or both eyes. http://Louis-J-Sheehan.us http://Louis-J-Sheehan.us/ http://louis-j-sheehan.us/page1.aspx http://louis-j-sheehan.us/Blog/blog.aspx http://louis-j-sheehan.us/AboutMe1.aspx http://louis-j-sheehan.us/page.aspx http://louis-j-sheehan.us/ImageGallery/CategoryList.aspx?id=a1206a74-5f7f-443f-97f5-9b389a4d4f9e&m=0 http://louis1j1sheehan.us/page3.aspx

In a public comment, Herbert Kauffman, MD, former chairman of ophthalmology at Louisiana State University, offered the ACIP a graphic description: "This is not going blind in peace and quiet," Kauffman told the ACIP. "This is an all-consuming pain patients live with every moment of every day for years."
The ACIP recommendation means insurers will be more likely to pay for shingles vaccination in 60-and-over patients.
In one of the first studies to detect cancer using RNA in saliva, researchers were able to differentiate patients with head and neck cancer from healthy subjects based on biomarkers found in their saliva, according to an article in the Dec. 15 issue of the journal Clinical Cancer Research.
Researchers at the University of California Los Angeles’ Jonsson Comprehensive Cancer Center reported in the March 2004 issue of Journal of Dental Research that people have about 3,000 clinically distinct types of RNA in their saliva. This discovery led to a novel clinical approach called salivary transcriptome diagnostics.
In a study to evaluate this diagnostic approach’s value, researchers collected unstimulated saliva from 32 subjects with cancers of the mouth, tongue, larynx and pharynx and 32 matched control subjects. When they extracted RNA from the saliva samples, they discovered that 1,679 genes were expressed at significantly different levels in the test subjects’ saliva than in the control subjects’ saliva.
Study results also showed that a combination of four RNA biomarkers provided a detectable signature for head and neck cancer. Researchers conducted a blinded second saliva screening and identified the signature in test subjects with 91 percent sensitivity and specificity.

American Experience Vietnam: A Television History
Vietnam was before my time, so this was a good introduction for me. I’m sure it can’t cover everything and I accept same. For me, the show leaves unaddressed one important question/decision. First, a quick review of some facts from the show:
1. Tonkin in summer of 1964; the communists might have assumed they were attacking South Vietnamese and/or the CIA so these facts don’t matter for my question. However, the Americans DID retaliate by bombing the North. 2. On the eve of the November 1964 elections, the Communists attacked an American airbase near Saigon that was being used against them; this was the first Communist attack against an American installation. The Americans did NOT retaliate. 3. December 24, 1964, the Communists bomb the Brinks Hotel which hotel was occupied/used by high-ranking American Officers. The Americans did NOT retaliate (“who could bomb Santa Claus?”). 4. The Communists attack an American airbase in the Central Highlands (“Pleiku”) killing 8 and wounding 126 (it is not clear from the show how many of the forgoing casualties were Americans). The Americans DID retaliate AND planned sustained bombing but the bombing was postponed because of a coup attempt in Saigon in February of 1965. 5. Sustained bombing does begin as Operation Rolling Thunder. 6. On March 8, 1965, 3,500 Marines are brought in to defend the three jet-capable American airbases (these 3,500 are mentioned in the context of DaNang). 7. Three weeks after these Marines land, the Communists attack the American embassy in Saigon. 8. Less than one month after landing, the Marines’ mission is expanded to engage in offensive patrols (“ … don’t sit on your dittyboxes ….”). 9. 72,000 American troops are “committed” by the end of Spring. 200,000 American troops are “committed” by the end of the year.
The question(s): Did the Communists think that these pinpricks would dissuade the Americans from entering the War? Or what did they think the probability was that these attacks would dissuade the Americans rather than cause them to escalate their efforts? Surely the Communists did NOT want the Americans to escalate their presence/effort? Louis J Sheehan http://Louis-J-Sheehan.us/

(AP) -- Scientists have apparently broken the universe's speed limit.
For generations, physicists believed there is nothing faster than light moving through a vacuum -- a speed of 186,000 miles per second.
But in an experiment in Princeton, New Jersey, physicists sent a pulse of laser light through cesium vapor so quickly that it left the chamber before it had even finished entering.
The pulse traveled 310 times the distance it would have covered if the chamber had contained a vacuum.
Researchers say it is the most convincing demonstration yet that the speed of light -- supposedly an ironclad rule of nature -- can be pushed beyond known boundaries, at least under certain laboratory circumstances. Not so impossible
"This effect cannot be used to send information back in time," said Lijun Wang, a researcher with the private NEC Institute. "However, our experiment does show that the generally held misconception that `nothing can travel faster than the speed of light' is wrong."
The results of the work by Wang, Alexander Kuzmich and Arthur Dogariu were published in Thursday's issue of the journal Nature.
The achievement has no practical application right now, but experiments like this have generated considerable excitement in the small international community of theoretical and optical physicists.
"This is a breakthrough in the sense that people have thought that was impossible," said Raymond Chiao, a physicist at the University of California at Berkeley who was not involved in the work. Chiao has performed similar experiments using electric fields.
In the latest experiment, researchers at NEC developed a device that fired a laser pulse into a glass chamber filled with a vapor of cesium atoms. The researchers say the device is sort of a light amplifier that can push the pulse ahead.
Previously, experiments have been done in which light also appeared to achieve such so-called superluminal speeds, but the light was distorted, raising doubts as to whether scientists had really accomplished such a feat.
The laser pulse in the NEC experiment exits the chamber with almost exactly the same shape, but with less intensity, Wang said.
The pulse may look like a straight beam but actually behaves like waves of light particles. The light can leave the chamber before it has finished entering because the cesium atoms change the properties of the light, allowing it to exit more quickly than in a vacuum.
The leading edge of the light pulse has all the information needed to produce the pulse on the other end of the chamber, so the entire pulse does not need to reach the chamber for it to exit the other side.
The experiment produces an almost identical light pulse that exits the chamber and travels about 60 feet before the main part of the laser pulse finishes entering the chamber, Wang said.
Wang said the effect is possible only because light has no mass; the same thing cannot be done with physical objects.
The Princeton experiment and others like it test the limits of the theory of relativity that Albert Einstein developed nearly a century ago.
According to the special theory of relativity, the speed of particles of light in a vacuum, such as outer space, is the only absolute measurement in the universe. The speed of everything else -- rockets or inchworms -- is relative to the observer, Einstein and others explained. Application: faster computers? http://louis-j-sheehan.us/page.aspx

In everyday circumstances, an object cannot travel faster than light. The Princeton experiment and others change these circumstances by using devices such as the cesium chamber rather than a vacuum.
Ultimately, the work may contribute to the development of faster computers that carry information in light particles.
Not everyone agrees on the implications of the NEC experiment.
Aephraim Steinberg, a physicist at the University of Toronto, said the light particles coming out of the cesium chamber may not have been the same ones that entered, so he questions whether the speed of light was broken.
Still, the work is important, he said: "The interesting thing is how did they manage to produce light that looks exactly like something that didn't get there yet?"

WASHINGTON, Iowa – John Edwards vowed Saturday that corporate lobbyists would not be allowed to work in his administration, if elected. “When I am president of the United States, no corporate lobbyists or anyone who has lobbied for a foreign government will work in my White House,” Mr. Edwards said, speaking at a public library. He followed it up with an implicit attack on Mr. Obama. “I hear people argue that the way you can get things done is you sit at a table with drug companies, insurance companies, oil companies and negotiate with them, and somehow they will voluntarily give away their power,” he said. “I think it is a complete fantasy.” In a November speech to Iowa Democrats, Mr. Obama promised that lobbyists would not work in his White House. “I have done more than any other candidate in this race to take on lobbyists, and I have won,” Mr. Obama said at the time. “They have not funded my campaign, they will not get a job in my White House, and they will not drown out the voices of the American people when I am president.” But he later amended his position, saying that lobbyists would not “dominate” his White House.”
Bill Burton, a spokesman for Mr. Obama, responded to Mr. Edwards’ announcement with a memo contrasting Mr. Obama’s record of lobbying reform proposals with Mr. Edwards’. “The truth is, in his six years as a U.S. Senator, John Edwards did not propose or accomplish a single thing to reduce the power of lobbyists while Barack Obama passed the most sweeping lobbying reform since Watergate,” Mr. Burton said in an e-mail message. When campaigning, Mr. Edwards frequently reminds voters that he has never taken campaign contributions from lobbyists. Mr. Obama has banned lobbyist contributions from his presidential campaign. But there are signs that potential caucusgoers are associating the message of fighting lobbyists and big corporations more with Mr. Edwards than with Mr. Obama. Jana Warren, an undecided voter, attended an Obama event last night in Muscatine, and then an Edwards event Saturday morning. After filing out of the Edwards event, she said she was leaning strongly toward Mr. Edwards. In the end, Ms. Warren said, her decision is guided by economic issues. “I think Mr. Obama is inspirational,” she said. “But I think corporate greed is a really big problem in our country, and I like what Mr. Edwards had to say about that.”

TEHRAN, Iran -- Russia is preparing to equip Iran with a powerful new air defense system that would dramatically increase its ability to repel an attack, Iran's defense minister said Wednesday.
The S-300 anti-aircraft missile defense system is capable of shooting down aircraft, cruise missiles and ballistic missile warheads at ranges of over 90 miles and at altitudes of about 90,000 feet. Russian military officials boast that its capabilities outstrip the U.S. Patriot missile system.
The S-300 is an improvement over the Tor-M1 air defense missile system. Russia delivered 29 Tor-M1s to Iran this year under a $700 million contract signed in December 2005.
"The S-300 air defense system will be delivered to Iran on the basis of a contract signed with Russia in the past," Iranian Defense Minister Mostafa Mohammad Najjar said, according to state television.
Mr. Najjar didn't say when or how many of the S-300 anti-aircraft missile defense systems would be shipped to Iran, and Russian officials declined to comment.
The Tor-M1 is capable of hitting aerial targets flying at up to 20,000 feet.
"While Tor-M1 missiles can hit targets at low altitude, S-300 missile have an extraordinary performance against targets at high altitude," Mr. Najjar said.
Russian officials wouldn't comment on the Iranian statement. Russian officials have consistently denied they were selling the S-300 to Iran. Iranian media reports have claimed the S-300 missile systems could inflict significant damage to the U.S. or Israeli forces, were they to attack Iran.
The U.S. had said in the past that it would not rule out military action as a way to halt Iran's nuclear enrichment, claiming it was using it as cover for weapons development. But earlier this month, Washington reversed course, concluding in an intelligence assessment that Iran stopped direct work on creating nuclear arms in 2003 and that the program remained frozen through at least the middle of this year.
Israel says Iran remains a strong threat, but most analysts think any Israeli military operation is unlikely at this point.
Teams led by Mikhail Dmitriyev, head of the Russian Federal Service for Military and Technical Cooperation, and Brigadier General Ahmad Vahidi, regarded as the father of Iran's missile program, held talks in Tehran this week on ways to step up defense cooperation. http://louis1j1sheehan.us/ImageGallery/CategoryList.aspx?id=36f0e6c9-8b8a-4f0a-8630-e5d3b879fad4&m=0

A military expert speaking on condition of anonymity because of the sensitivity of the subject said that the Russian team included experts who had installed the Tor-M1 in Iran.
Dmitriyev told the Russian Itar-Tass news agency Wednesday said air defense and radar systems were priorities in Russian-Iranian defense discussions.
Russia has provided Iran with Kilo-Class submarines, MIG and Sukhoi military planes and bombers in recent decades.
Iran-Russia ties increased after a visit here by Russian President Vladimir Putin in October.
A KEY GAUGE of U.S. home prices shows they are falling sharply across most of the nation, as a deepening slump in the housing market threatens to damp consumer spending.
Export-driven economies across Asia are keeping a close eye on U.S. spending trends as they brace for a possible slowdown.
Home prices in 10 major U.S. metropolitan areas in October were down 6.7% from a year earlier, according to the S&P/Case-Shiller home-price indexes, released Wednesday by credit-rating firm Standard & Poor's. That exceeded the previous record year-to-year decline of 6.3% in April 1991, when the economy was emerging from a recession.
New statistics from the U.S. Census Bureau, meanwhile, indicate a slowdown in the number of Americans moving to states that led the housing boom, including Nevada, Florida and Arizona.
The silver lining behind the latest home-price data is that they signal the market is making what most economists see as a necessary adjustment, dragging home prices back into closer alignment with Americans' ability to pay. The market is working its way "back to reality," says David Seiders, chief economist of the National Association of Home Builders. He thinks U.S. house prices will bottom out by early 2009.
Some other economists say that might not happen before 2010. "The housing shock is only about halfway over, and housing prices will continue to fall well into 2009," says Lehman Brothers economist Michelle Meyer.
During the housing boom in the first half of this decade, fast-rising home prices made it easy for homeowners to take out home-equity loans or refinance their primary mortgages to extract some cash. That helped sustain consumer spending, which accounts for about 70% of U.S. economic activity.
Economists now worry that falling home prices will prompt U.S. consumers to pull back on spending enough to slow growth or even tip the economy into recession. "Eventually what's happening in the housing market is going to catch up with us," says Patrick Newport, an economist at research-firm Global Insight Inc.
Fears of a sharp drop in consumption were assuaged somewhat last week with a report that U.S. consumer spending in November grew at the fastest pace in 31⁄2 years. And though holiday sales fell short of retailers' expectations, consumers, spurred by discounts, spent heavily in the final days before Christmas. Economists say that even if overall spending slows in December, the strength seen in October and November would be enough to keep the U.S. economy afloat in the near term.

"The most important determinant of [spending] is always income," says Harm Bandholz, an economist at UniCredit in New York. He said that Americans' disposable income has risen a "solid" 2.5% over last year. He and others say that as long as the job market holds up and incomes keep growing, Americans will continue to spend.
The S&P/Case-Shiller index showed that some of the fastest declines in home prices are in metropolitan areas that were among the hottest during the housing boom. Prices were down 12.4% from a year earlier in Miami, 11.1% in San Diego, 10.7% in Las Vegas and 10.6% in Phoenix.
Home prices are still up from a year ago in some U.S. cities, such as Seattle and Charlotte, N.C. And people who bought their homes several years ago still are sitting on sizable gains in most of the country.
The boom more than doubled prices in many populous areas near the coasts of the U.S. The run-up was fueled in part by unusually low interest rates, which slashed the cost of monthly mortgage payments. In addition, in the wake of the technology-stock bubble, many Americans viewed real estate as a safer investment than stocks, and so poured increasing sums into second homes and rental properties.
U.S. home sales began to slow in mid-2005. Prices leveled off and then started declining in 2006. Over the past year, mortgage defaults have soared, leading to rapid growth in foreclosures.
As the market adjusts, single-family housing starts have fallen 55% from their January 2006 peak to a seasonally adjusted annual rate of 829,000. In recent months, lenders and investors have begun owning up to billions of dollars of losses on mortgages and related securities, clearing the decks for an eventual revival in lending.
But the recovery of the housing market is likely to be a gradual process. That's partly because the boom left prices so far out of whack with incomes. As measured by the S&P/Case-Shiller national index, home prices jumped 74% in the six years through 2006. During the same period, U.S. median household income rose 15%. (Neither figure is adjusted for inflation.) That made housing unaffordable for many Americans.
For a few years, lax lending standards -- some loans required no down payments and offered low introductory interest rates -- meant U.S. borrowers could buy more expensive houses than they could really afford. But lenders have been burned by a surge in defaults that started in 2006, and such mortgages generally are no longer available. That means house prices will have to fall to a level potential buyers can afford.
Mark Zandi, chief economist of Moody's Economy.com, a research firm in West Chester, Pennsylvania, predicts that on average U.S. house prices will decline about 12% by the second quarter of 2009 from their peak in the second quarter of 2006. He expects household income to rise by about the same amount over that period.
Prices of new homes are likely to start recovering in the first half of 2008 because builders are aggressively chopping prices to clear inventories, says Edward Leamer, an economics professor at the University of California, Los Angeles.
On average, prices of previously occupied homes, as measured by the S&P/Case-Shiller indexes, are likely to drop another 7% in 2008 before flattening out in 2009, says Thomas Lawler, a housing economist in Vienna, Virginia.
Inventories of unsold homes remain very high and may increase in the new year as lenders dump more foreclosed houses on the U.S. market. The number of detached single-family homes listed for sale in October was enough to last 101⁄2 months at the current sales rate, according to the National Association of Realtors.

The mortgage market also needs to adjust further. Most of the funding for home loans comes from investors who buy securities backed by bundles of mortgages. Since August, many of those investors have shunned the market amid fears of rising defaults.
The current scarcity of funds available for mortgage lending creates a chicken-and-egg situation, says Prof. Leamer. Investors who provide funding for home loans don't want to commit more money until they believe the housing market is getting better. But it is hard for the housing market to rebound as long as mortgage credit is tight. Lower prices eventually will break this impasse, by luring buyers back into the market, he says.

Population growth in several of the fastest-growing states is slowing -- in Arizona, Florida and Nevada, in particular -- in a trend both reflecting and fueling the housing-market malaise in those areas.
"This is our first chance to see what has been the migration impact of the housing-market slowdown, and it's showing up in these highflying states," says William Frey, a demographer at the Brookings Institution, a Washington think tank.
• The Census Shows: Growth in several of the fastest-growing states has slowed. • What It Reveals: Malaise in the housing market is changing the way Americans relocate. • Bottom Line: The West and South continue to gain residents from the Midwest and Northeast. • Home-Price Declines Accelerate1
The Census Bureau's annual estimate of state population changes covers the 12 months that ended July 1. It shows that people continue to flee the Midwest -- especially Michigan, one of two states to lose people -- and that the Mountain states in the West continue to post large population gains as people arrive from California and elsewhere.
Arizona, Florida and Nevada are still among the fastest-growing states in the country, by percentage. Nevada saw an increase of 2.9%, or 72,955 people, tallying births, deaths and migration from inside and outside the U.S.
That was less than the previous year's 3.5% increase and lower than the 3%-plus growth rate for the six previous years. Arizona, the second-fastest-growing state, saw its population increase 2.8% in the most recent period, compared with a 3.6% rise in the previous year.
Florida, which has suffered heavily in the housing bust, saw the sharpest falloff in population growth. Florida grew 1.07%, slightly faster than the U.S. growth rate of 0.96%. During the year, 35,301 people moved to Florida from another state, 134,798 fewer than in the previous year. That is the slowest rate of domestic migration into Florida since at least 1990, the year the Census Bureau began publishing annual estimates of migration between states.
Pain in the manufacturing sector, especially auto manufacturing, continued to purge residents from the Midwest. Michigan lost 30,500 residents, a 0.3% decline. Ohio was essentially flat, gaining 3,404. Besides Michigan, the only state to lose population was Rhode Island.
http://louis2j2sheehan.us/page1.aspx
http://louis1j1sheehan.us/Blog/blog.aspx
Broadly, people in the Northeast and Midwest continue to leave for the West and South. Utah and Idaho were the third- and fourth-fastest-growing states, respectively. Colorado and Wyoming were eighth and ninth, respectively. Both states saw their rate of growth increase.
Residents of California, on the other hand, continue to leave: In the most recent period, 263,035 people left California for another state. The state's 0.8% population growth was mostly because of births.
In the South, states including Georgia and North Carolina have taken the fast-growing mantle away from Florida, while Texas continues to suck up new residents. Georgia and North Carolina grew 2.17% and 2.16%, respectively. Texas grew 2.12%. Those states also are among the biggest gainers in absolute terms. Texas gained 496,751 residents, more than any other state. Georgia had the third-largest increase, with 202,670, and North Carolina was fifth, with 191,590.

Following the exodus of residents after Hurricane Katrina, Louisiana added about 50,000 people in the year to July 1. There is still a ways to go, though: From July 2005 to July 2006, the state lost about 220,000 residents.

In May 2004, the White House dispatched the U.S. ambassador in Germany to pay an unusual visit to that country's interior minister. Ambassador Daniel R. Coats carried instructions from the State Department transmitted via the CIA's Berlin station because they were too sensitive and highly classified for regular diplomatic channels, according to several people with knowledge of the conversation.
Coats informed the German minister that the CIA had wrongfully imprisoned one of its citizens, Khaled Masri, for five months, and would soon release him, the sources said. There was also a request: that the German government not disclose what it had been told even if Masri went public. The U.S. officials feared exposure of a covert action program designed to capture terrorism suspects abroad and transfer them among countries, and possible legal challenges to the CIA from Masri and others with similar allegations.
The Masri case, with new details gleaned from interviews with current and former intelligence and diplomatic officials, offers a rare study of how pressure on the CIA to apprehend al Qaeda members after the Sept. 11, 2001, attacks has led in some instances to detention based on thin or speculative evidence. The case also shows how complicated it can be to correct errors in a system built and operated in secret.
The CIA, working with other intelligence agencies, has captured an estimated 3,000 people, including several key leaders of al Qaeda, in its campaign to dismantle terrorist networks. It is impossible to know, however, how many mistakes the CIA and its foreign partners have made.
Unlike the military's prison for terrorist suspects at Guantanamo Bay, Cuba -- where 180 prisoners have been freed after a review of their cases -- there is no tribunal or judge to check the evidence against those picked up by the CIA. The same bureaucracy that decides to capture and transfer a suspect for interrogation-- a process called "rendition" -- is also responsible for policing itself for errors.
The CIA inspector general is investigating a growing number of what it calls "erroneous renditions," according to several former and current intelligence officials.
One official said about three dozen names fall in that category; others believe it is fewer. The list includes several people whose identities were offered by al Qaeda figures during CIA interrogations, officials said. One turned out to be an innocent college professor who had given the al Qaeda member a bad grade, one official said.
"They picked up the wrong people, who had no information. In many, many cases there was only some vague association" with terrorism, one CIA officer said.
While the CIA admitted to Germany's then-Interior Minister Otto Schily that it had made a mistake, it has labored to keep the specifics of Masri's case from becoming public. As a German prosecutor works to verify or debunk Masri's claims of kidnapping and torture, the part of the German government that was informed of his ordeal has remained publicly silent. Masri's attorneys say they intend to file a lawsuit in U.S. courts this week.
Masri was held for five months largely because the head of the CIA's Counterterrorist Center's al Qaeda unit "believed he was someone else," one former CIA official said. "She didn't really know. She just had a hunch."

http://louis-j-sheehan.us/page1.aspx
http://Louis-J-Sheehan.us/ The CIA declined to comment for this article, as did Coats and a spokesman at the German Embassy in Washington. Schily did not respond to several requests for comment last week.
CIA officials stress that apprehensions and renditions are among the most sure-fire ways to take potential terrorists out of circulation quickly. In 2000, then-CIA Director George J. Tenet said that "renditions have shattered terrorist cells and networks, thwarted terrorist plans, and in some cases even prevented attacks from occurring." The Counterterrorist Center
After the September 2001 attacks, pressure to locate and nab potential terrorists, even in the most obscure parts of the world, bore down hard on one CIA office in particular, the Counterterrorist Center, or CTC, located until recently in the basement of one of the older buildings on the agency's sprawling headquarters compound. With operations officers and analysts sitting side by side, the idea was to act on tips and leads with dramatic speed.
The possibility of missing another attack loomed large. "Their logic was: If one of them gets loose and someone dies, we'll be held responsible," said one CIA officer, who, like others interviewed for this article, would speak only anonymously because of the secretive nature of the subject.
To carry out its mission, the CTC relies on its Rendition Group, made up of case officers, paramilitaries, analysts and psychologists. Their job is to figure out how to snatch someone off a city street, or a remote hillside, or a secluded corner of an airport where local authorities wait.
Members of the Rendition Group follow a simple but standard procedure: Dressed head to toe in black, including masks, they blindfold and cut the clothes off their new captives, then administer an enema and sleeping drugs. They outfit detainees in a diaper and jumpsuit for what can be a day-long trip. Their destinations: either a detention facility operated by cooperative countries in the Middle East and Central Asia, including Afghanistan, or one of the CIA's own covert prisons -- referred to in classified documents as "black sites," which at various times have been operated in eight countries, including several in Eastern Europe.
In the months after the Sept. 11 attacks, the CTC was the place to be for CIA officers wanting in on the fight. The staff ballooned from 300 to 1,200 nearly overnight.
"It was the Camelot of counterterrorism," a former counterterrorism official said. "We didn't have to mess with others -- and it was fun."
Thousands of tips and allegations about potential threats poured in after the attacks. Stung by the failure to detect the plot, CIA officers passed along every tidbit. The process of vetting and evaluating information suffered greatly, former and current intelligence officials said. "Whatever quality control mechanisms were in play on September 10th were eliminated on September 11th," a former senior intelligence official said.
J. Cofer Black, a professorial former spy who spent years chasing Osama bin Laden, was the CTC's director. With a flair for melodrama, Black had earned special access to the White House after he briefed President Bush on the CIA's war plan for Afghanistan.
Colleagues recall that he would return from the White House inspired and talking in missionary terms. Black, now in the private security business, declined to comment.

Some colleagues said his fervor was in line with the responsibility Bush bestowed on the CIA when he signed a top secret presidential finding six days after the 9/11 attacks. It authorized an unprecedented range of covert action, including lethal measures and renditions, disinformation campaigns and cyber attacks against the al Qaeda enemy, according to current and former intelligence officials. Black's attitude was exactly what some CIA officers believed was needed to get the job done.
Others criticized Black's CTC for embracing a "Hollywood model" of operations, as one former longtime CIA veteran called it, eschewing the hard work of recruiting agents and penetrating terrorist networks. Instead, the new approach was similar to the flashier paramilitary operations that had worked so well in Afghanistan, and played well at the White House, where the president was keeping a scorecard of captured or killed terrorists.
The person most often in the middle of arguments over whether to dispatch a rendition team was a former Soviet analyst with spiked hair that matched her in-your-face personality who heads the CTC's al Qaeda unit, according to a half-dozen CIA veterans who know her. Her name is being withheld because she is under cover.
She earned a reputation for being aggressive and confident, just the right quality, some colleagues thought, for a commander in the CIA's global war on terrorism. Others criticized her for being overzealous and too quick to order paramilitary action. The CIA and Guantanamo Bay
One way the CIA has dealt with detainees it no longer wants to hold is to transfer them to the custody of the U.S. military at Guantanamo Bay, where defense authorities decide whether to keep or release them after a review.
About a dozen men have been transferred by the CIA to Guantanamo Bay, according to a Washington Post review of military tribunal testimony and other records. Some CIA officials have argued that the facility has become, as one former senior official put it, "a dumping ground" for CIA mistakes.
But several former intelligence officials dispute that and defend the transfer of CIA detainees to military custody. They acknowledged that some of those sent to Guantanamo Bay are prisoners who, after interrogation and review, turned out to have less valuable information than originally suspected. Still, they said, such prisoners are dangerous and would attack if given the chance.
Among those released from Guantanamo is Mamdouh Habib, an Egyptian-born Australian citizen, apprehended by a CIA team in Pakistan in October 2001, then sent to Egypt for interrogation, according to court papers. He has alleged that he was burned by cigarettes, given electric shocks and beaten by Egyptian captors. After six months, he was flown to Guantanamo Bay and let go earlier this year without being charged.
Another CIA former captive, according to declassified testimony from military tribunals and other records, is Mohamedou Oulad Slahi, a Mauritanian and former Canada resident, who says he turned himself in to the Mauritanian police 18 days after the 9/11 attacks because he heard the Americans were looking for him. The CIA took him to Jordan, where he spent eight months undergoing interrogation, according to his testimony, before being taken to Guantanamo Bay. http://louis2j2sheehan.us/page1.aspx

Another is Muhammad Saad Iqbal Madni, an Egyptian imprisoned by Indonesia authorities in January 2002 after he was heard talking -- he says jokingly -- about a new shoe bomb technology. He was flown to Egypt for interrogation and returned to CIA hands four months later, according to one former intelligence official. After being held for 13 months in Afghanistan, he was taken to Guantanamo Bay, according to his testimony. The Masri Case
Khaled Masri came to the attention of Macedonian authorities on New Year's Eve 2003. Masri, an unemployed father of five living in Ulm, Germany, said he had gone by bus to Macedonia to blow off steam after a spat with his wife. He was taken off a bus at the Tabanovce border crossing by police because his name was similar to that of an associate of a 9/11 hijacker. The police drove him to Skopje, the capital, and put him in a motel room with darkened windows, he said in a recent telephone interview from Germany.
The police treated Masri firmly but cordially, asking about his passport, which they insisted was forged, about al Qaeda and about his hometown mosque, he said. When he pressed them to let him go, they displayed their pistols.
Unbeknown to Masri, the Macedonians had contacted the CIA station in Skopje. The station chief was on holiday. But the deputy chief, a junior officer, was excited about the catch and about being able to contribute to the counterterrorism fight, current and former intelligence officials familiar with the case said.
"The Skopje station really wanted a scalp because everyone wanted a part of the game," a CIA officer said. Because the European Division chief at headquarters was also on vacation, the deputy dealt directly with the CTC and the head of its al Qaeda unit.
In the first weeks of 2004, an argument arose over whether the CIA should take Masri from local authorities and remove him from the country for interrogation, a classic rendition operation.
The director of the al Qaeda unit supported that approach. She insisted he was probably a terrorist, and should be imprisoned and interrogated immediately.
Others were doubtful. They wanted to wait to see whether the passport was proved fraudulent. Beyond that, there was no evidence Masri was not who he claimed to be -- a German citizen of Arab descent traveling after a disagreement with his wife.
The unit's director won the argument. She ordered Masri captured and flown to a CIA prison in Afghanistan.
On the 23rd day of his motel captivity, the police videotaped Masri, then bundled him, handcuffed and blindfolded, into a van and drove to a closed-off building at the airport, Masri said. There, in silence, someone cut off his clothes. As they changed his blindfold, "I saw seven or eight men with black clothing and wearing masks," he later said in an interview. He said he was drugged to sleep for a long plane ride. Afghanistan
Masri said his cell in Afghanistan was cold, dirty and in a cellar, with no light and one dirty cover for warmth. The first night he said he was kicked and beaten and warned by an interrogator: "You are here in a country where no one knows about you, in a country where there is no law. If you die, we will bury you, and no one will know."
Masri was guarded during the day by Afghans, he said. At night, men who sounded as if they spoke American-accented English showed up for the interrogation. Sometimes a man he believed was a doctor in a mask came to take photos, draw blood and collect a urine sample.
Back at the CTC, Masri's passport was given to the Office of Technical Services to analyze. By March, OTS had concluded the passport was genuine. The CIA had imprisoned the wrong man.
At the CIA, the question was: Now what? Some officials wanted to go directly to the German government; others did not. Someone suggested a reverse rendition: Return Masri to Macedonia and release him. "There wouldn't be a trace. No airplane tickets. Nothing. No one would believe him," one former official said. "There would be a bump in the press, but then it would be over."
Once the mistake reached Tenet, he laid out the options to his counterparts, including the idea of not telling the Germans. Condoleezza Rice, then Bush's national security adviser, and Deputy Secretary of State Richard L. Armitage argued they had to be told, a position Tenet took, according to one former intelligence official. http://louis2j2sheehan.us/page1.aspx

"You couldn't have the president lying to the German chancellor" should the issue come up, a government official involved in the matter said.
Senior State Department officials decided to approach Interior Minister Schily, who had been a steadfast Bush supporter even when differences over the Iraq war strained ties between the two countries. Ambassador Coats had excellent rapport with Schily.
The CIA argued for minimal disclosure of information. The State Department insisted on a truthful, complete statement. The two agencies quibbled over whether it should include an apology, according to officials.
Meanwhile, Masri was growing desperate. There were rumors that a prisoner had died under torture. Masri could not answer most questions put to him. He said he steadied himself by talking with other prisoners and reading the Koran.
A week before his release in late May 2004, Masri said he was visited in prison by a German man with a goatee who called himself Sam. Masri said he asked him if he were from the German government and whether the government knew he was there. Sam said he could not answer either question.
"Does my wife at least know I'm here?" Masri asked.
"No, she does not," Sam replied, according to Masri.
Sam told Masri he was going to be released soon but that he would not receive any documents or papers confirming his ordeal. The Americans would never admit they had taken him prisoner, Sam added, according to Masri.
On the day of his release, the prison's director, who Masri believed was an American, told Masri that he had been held because he "had a suspicious name," Masri said in an interview.
Several intelligence and diplomatic officials said Macedonia did not want the CIA to bring Masri back inside the country, so the agency arranged for him to be flown to Albania. Masri said he was taken to a narrow country road at dusk. When they let him off, "They asked me not to look back when I started walking," Masri said. "I was afraid they would shoot me in the back."
He said he was quickly met by three armed men. They drove all night, arriving in the morning at Mother Teresa Airport in Tirana. Masri said he was escorted onto the plane, past all the security checkpoints, by an Albanian.
Masri has been reunited with his children and wife, who had moved the family to Lebanon because she did not know where her husband was. Unemployed and lonely, Masri says neither his German nor Arab friends dare associate with him because of the publicity.
Meanwhile, a German prosecutor continues to work Masri's case. A Macedonia bus driver has confirmed that Masri was taken away by border guards on the date he gave investigators. A forensic analysis of Masri's hair showed he was malnourished during the period he says he was in the prison. Flight logs show a plane registered to a CIA front company flew out of Macedonia on the day Masri says he went to Afghanistan. http://louis2j2sheehan.us/page1.aspx

Masri can find few words to explain his ordeal. "I have very bad feelings" about the United States, he said. "I think it's just like in the Arab countries: arresting people, treating them inhumanly and less than that, and with no rights and no laws."

Computer giant IBM will build the world's most powerful supercomputer at a US government laboratory.
The machine, codenamed Roadrunner, could be four times more potent than the current fastest machine, BlueGene/L, also built by IBM.
The new computer is a "hybrid" design, using both conventional supercomputer processors and the new "cell" chip designed for Sony's PlayStation 3.
Roadrunner will be installed at the Los Alamos National Laboratory, New Mexico.
The laboratory is owned by the US Department of Energy (DOE). Eventually the machine could be used for a programme that ensures the US nuclear weapons stockpile remains safe and reliable, the DOE said in a statement.
Using supercomputers to simulate how nuclear materials age negates arguments for the resumption of underground nuclear testing.
Peak speeds
The new machine will be able to achieve "petaflop speeds," said IBM. One petaflop is the equivalent of 1,000 trillion calculations per second.
Running at peak speed, it will be able to crunch through 1.6 thousand trillion calculations per second.
TOP FIVE SUPERCOMPUTERS Blue Gene/L, Lawrence Livermore National Laboratory, California. (131,072 processors) BGW Blue Gene, IBM Thomas J. Watson Research Center, New York (40,960 processors) ASC Purple, Department of Energy, USA (12,208 processors) Columbia, NASA Ames Research Center, USA (10,160 processors) Tera-10, Commissariat a l'Energie Atomique (CEA), France (8,704 processors) Source: Top 500 Supercomputers
By comparison, BlueGene/L is capable of mere "teraflop" (trillion calculations per second) speeds.
Installed at the DOE's Lawrence Livermore National Laboratory in California and also used for the DOE's Stockpile Stewardship Program, it has achieved 280.6 teraflops and is theoretically capable of 367 teraflops.
Roadrunner should be capable of much more. It will achieve its superfast performance using a hybrid design, built with off-the-shelf components.
The computer will contain 16,000 standard processors working alongside 16,000 "cell" processors, designed for the PlayStation 3 (PS3).
Each cell chip consists of eight processors controlled by a master unit that can assign tasks to each member of the processing team. Each cell is capable of 256 billion calculations per second.
The power of the cell chip means Roadrunner needs far fewer processors than its predecessors.
Spare power
This is not the first attempt by scientists to harness the power of the cell.
In August, scientists at Stanford University in California announced plans to distribute a program that could run on gamers' PS3s.
The folding@home program would tap the cell's spare processing power to examine how the shape of proteins, critical to most biological functions, affect diseases such as Alzheimer's.
This distributed computing method uses each individual machine to process a small amount of data, with results fed back over the internet to a central machine where they can be viewed together.
The Stanford researchers say that 10,000 consoles running the program would give a performance equivalent to one petaflop. The team hopes eventually to enlist 100,000 machines.
Although a network of this size would in theory out-perform Roadrunner, the two systems would be used to solve different types of problem.
Computer talk
Both involve huge sets of data that are split into smaller packets to make them more manageable.
On a distributed computing network these small packets can be processed independently, with results brought together at key stages of a project.
For example a PC running the SETI@home project, which examines thousands of hours of radio telescope signals for signs of extra-terrestrial intelligence, processes just a small chunk of data.
Finding a signal does not depend on the outcome of other PCs running the program.
However, on a supercomputer like Roadrunner, the different units must be able to "talk" with each other all of the time, which is vital for applications such as weather simulation which feature a huge number of constantly changing and interacting variables.
When Roadrunner is finished in 2008 it will cover 12,000 square feet (1,100 square metres) of floor space at Los Alamos National Laboratory

Board gaming is a hobby that has always been dear to me. My interest in the field is wide, ranging from simple and straightforward “social” games such as the relatively recent “Carcassonne” to far more complex rule monstrosities like the 1990 Avalon Hill game “Republic of Rome”.
Therefore, when I recently learnt about the existence of a samurai warfare game called “Ran”, which borrows its name from the Kurosawa movie (even acknowledging its source) and comes in a box whose cover is clearly inspired by Kagemusha, I knew that I had to get the game. And get it I did.
In fact, to be completely fair to the reader, I must mention that when I contacted the manufacturer of the game, they kindly offered to send me a review copy. You may judge yourself the impact that this may or may not have had on what follows.
In any case, I have now had the opportunity to sit down for a couple of games of “Ran”, and I think that my early impressions of the game are enough to warrant writing a review. For those who are either too busy or too lazy to read the whole piece, let me give you the opportunity to skip the details by saying that I really like the game. The rest of you, read on.
A note: While playing, I took a series of pictures with which to illustrate this article, but it seems that I have lost the cable with which to transfer those pictures from my camera to the computer. As for now, I will publish this without the illustrations, and anyone interested in checking how the game actually looks like can check Board Game Geek’s Ran picture gallery.

http://Louis-J-Sheehan.us
On the surface of things, the board game “Ran” has very little in common with the movie “Ran”, or indeed with any of Kurosawa’s movies. This is of course understandable, considering that the game is about military strategy, whereas none of Kurosawa’s movies really centrally deal with warfare, but rather, when it is present, use it as a backdrop and a metaphoric device. “Ran”, therefore, is not “based on” or even “inspired by Akira Kurosawa’s Ran”, and neither does it claim that.
Furthermore, to the best of my knowledge the battles available in “Ran” the strategy game in no way correspond with the ones in Kurosawa’s “Ran” or “Kagemusha”. ( “Samurai”, an earlier game by the same maker, includes the Battle of Nagashino, which is the final battle in “Kagemusha”.) The connection is therefore in some ways very superficial, indeed almost accidental.
Yet, while playing “Ran”, you will probably sooner or later catch yourself humming the theme of either “Ran” or “Kagemusha”. Even without any actual one-to-one correspondence between the game and the movies, each can help to better understand the other. The movie helps you visualize the game, while by playing the game you come to understand the mechanics behind Japanese warfare depicted in the films. There is also something quite epic, or as the box text puts it “Homeric” about the board game, on a level similar to Kurosawa’s endeavors.
Consequently, while “Ran” the board game is not exactly a “Kurosawa item”, it is certainly something that I would imagine might interest a number of devoted Kurosawa fans.
Introduction
“Ran”, published in 2007, is the 12th volume in the “Great Battles of History” series by the well-known game publisher GMT Games. The company is perhaps best known for its war games that strive for historical accuracy, often with the result of added complexity in the rules. “Ran” is in fact the second samurai warfare game in the series, following the 1996 game that was simply titled “Samurai”.
The battles included in the box range in printed playing time from roughly two to “more than five” hours. My impression is that these figures are fairly realistic for someone already familiar with the rules. Your first battle, however, will most probably take about a double the estimated time. As for the complexity of the game, I have seen both more complex, as well as far simpler games. I would say that as board games go, “Ran” is somewhere towards the lower end of the “high” complexity games.
I have previously not played “Samurai”, or any of the other “Great Battles of History” games, so I had to approach “Ran” with only my previous experience as a gamer to fall on. http://louis-j-sheehan.us/Blog/blog.aspx
http://Louis-J-Sheehan.us/
The game
“Ran” comes with seven scenarios, each representing a battle from the late 16th and early 17th century feudal Japan, which was part of the so-called “Warring States” period. Because of it being the second samurai war game in the GMT series, the battles on offer are somewhat lesser known than are the ones in its predecessor “Samurai”. This, of course, in no way makes the scenarios themselves less interesting to play, and in any case I wonder how many people actually are more familiar with, say, the Battle of Sekigahara (not included) than for example the Battle of Mimigawa (included).
Based on the scenarios that I have tried alone and with a friend, the rule system in “Ran” seems well balanced and certainly faithful enough to the historical reality that was feudal Japanese warfare. In fact, since I cannot claim to be an expert in this particular field, I enlisted for the testing purposes a board gaming friend who is a trained historian working in a library of military science, and thus capable of bringing some relevant knowledge and authority to the table. The game clearly received his seal of approval, for as I am typing this review, he keeps harassing me with messages about when the next session is to take place. Which, by the way, will probably be quite soon, as I am just as eager to try the game again – not least to attempt to have my revenge after being so miserably crushed in Nagakute!
“Ran”, as the name suggests (“ran” is Japanese for “chaos”), employs a turn system that does away with strict linearity. Rather than each player moving all of his units and then passing the turn to the next player, the system allows for frequent changes of initiative, and a single game turn may easily see both players moving different parts of their army at very different times. http://louis2j2sheehan.us/Blog/Blogger.aspx
How this work is that, without going into unnecessary details, the more skilled your commanders, the better hold of the flow of the battle you will have. In gaming terms, this means that capable and lucky generals (who each command individual parts of your army) may be able to move up to three times in a single turn, giving them a clear edge in the battle. In fact, in our early test games this sometimes felt like too much of an edge, although this may only be me complaining against my friend’s amazingly good luck with the so-called Momentum dice-rolls. http://louisjsheehan.blogspot.com/
http://ljsheehan.blogspot.com/
http://louis9j9sheehan.blogspot.com/
While the above is a slight variation of a relatively standard war gaming practice, “Ran” is somewhat different from your typical tactical war game in that it incorporates individual combat into a system otherwise concentrating on units comprised of a few hundred men. The way the game does this is fairly interesting, and something that I still need to experiment with to make a full tactical use of. On the basic level, however, what happens is that individual samurai or busho (generals) can enter into head-to-head fights with each other in the midst of the chaos around them. With a little luck, these individual feats may then change the direction of the whole battle, if they happen to take place at the right moment.
My only real complaint about the individual combat system is that while the idea itself is very intriguing, the rules behind its execution are somewhat less so. You basically compare the fighting characters’ abilities and throw dice, the one with the lower total suffering a wound. If a character’s stamina runs to zero, he dies, although you can withdraw before that. This, I feel, could have been made more tactical and interesting by extending the rules somewhat, allowing for different types of attacks (perhaps ranging from all-out defense to all-out attack) and maybe even mapping the hits to different body parts to make the fight more visual. But maybe I come here too strongly from my background as someone who has practiced kendo (“Japanese fencing”) and plays role playing games with systems similar to the above – perhaps it might, in fact, be taking the individual combat too far in a game that is, after all, a tactical war game.
Individual feats are important also outside of the immediate head-to-head combat. As mentioned before, each part of your army has its own commander, and the commander’s personal skills reflect how well he will be able to maneuver his troops. Similarly, your whole army – including the commanders – sit under your main commander, whose stats again have an influence over the proceedings.
These commanders also take personal responsibility over their (your) decisions in a way that the game designers have tried to tie with the bushido (warrior’s “code of conduct”) culture that is at the centre of medieval Japanese warfare. For example, when ordering a withdrawal of his troops, a commander may in some cases have to, as a result of losing face, commit seppuku (ritual suicide). This is, in fact, how our Battle of Nagakute ended, with my commander-in-chief Ieyasu Tokugawa being forced to take his own life after ordering a tactical withdrawal with the idea to save and rest his troops. His death then caused panic within the lines, and large parts of the army left the battle field, handing the victory to my opponent.
All in all, “Ran” is a very interesting mixture of troop and individual level warfare that is in some ways very traditional (which is good), but also unique (which is also good). As a result, it seems like a safe bet for anyone enjoying tactical war games, while a determined newcomer may also find the game a good introduction to the genre. I am certainly hooked, myself.
If, however, the most tactical war game that you have ever played and ever want to play is Risk, read into the rules before you fork out the money to buy “Ran”, as it may not quite be your cup of tea. Then again, it may also turn out to be the beginning of a beautiful new hobby, for which “Ran” can in fact serve as a relatively good and quite straightforward introduction.
The components
If you have never played board war games before, you may on your first impression of “Ran” be overwhelmed by the number of components that the box contains: seven maps printed on two large sheets of paper, over a thousand counters marking your units and their various states, a rule book and a scenario book, plus a number of charts and table cards littered with information. GMT also provides you with Ziploc bags to hold the counters in, which is extremely nice of them, considering that one will need those bags anyway, yet always forgets to buy any for a new game.
The maps in “Ran” predictably serve as the gaming board, and are of relatively good quality paper. Card board maps would, of course, be superior, but including seven cardboard maps the size of these babies would obviously raise the manufacturing and printing costs considerably.
One of the biggest problems that hex based games which work with a large variety of counters have is that the hexagons provided on the map are too small to actually comfortably hold all the counters. The problem is present also in “Ran”. For, even if a single hex in the game can only have one unit in it, it will ultimately also have to house a number of non-unit counters along with it, thus creating stacks (or in our case piles) of chits on the map. Furthermore, since the facing of the units is important, moving the counters around without accidentally changing the facings of surrounding units is difficult. Especially so, if you have fingers the size of Southern Europe, as I do.
One possible solution to this could be to keep the non-unit markers out of the actual map, referencing them on a separate sheet. Since the units, however, have no individual IDs, this is impossible without actually drawing something on the unit counters, which again is something that I am not going to do purely for aesthetic reasons.
The 24-page rule book starts by noting that the rule system in “Ran” is less complex than in the games that have preceded it in the series. It even goes as far as to suggest that a total newcomer to the genre of historically accurate war games will in 20-30 minutes be able to learn the rules to the point where “you’ll be just as good at this sort of thing as we are”.
Now, either this latter statement is a downright lie, I am a poor learner, or the guys over at GMT actually have no idea how their rule system works. For, at least in my case, it took almost two hours of flipping through the rule book until I reached the point where I was comfortable setting up the first scenario to test the game. In the end, it wasn’t until about four hours into active gaming that I started to feel like I mastered the basic rules in a way where I wasn’t making all that many mistakes.
Sadly, in fact, it is the rule book that is the weakest link in the “Ran” package. By this I do not mean the rules themselves, but the way that they are explained. The rule book lacks a real index, and the order in which the rules are presented seems fairly illogical to me. Add to this the high number of typos, grammatical errors and a few completely missing words here and there, and your initial enthusiasm towards the system is somewhat lessened as you try to make head or tale of it.
What I personally felt was most importantly missing from the rule book was a stronger historical background to many of the rules. Quick, short notes about why things work as they do would have helped at least me to remember the rules faster. Similarly, I often found myself wishing for more examples for rules that felt unclear for a long time. Perhaps GMT could even have considered adding to the package a book in which the reader is taken through a sample battle move by move, thus explaining the rules with real examples.
All this being said, once you actually get to the point where the system starts to make sense to you, you discover that the effort has easily been worth it.
Longevity
One big question that always hangs in the air in the case of board games that depict individual battles concerns longevity. After all, if what you get is a set number of historically accurate battles, how many times can you play through them without the act becoming repetitive? Similarly, since many of the battles included in “Ran” are quite lob-sided in that one side is heavily favored to win from the outset, how interesting can such games be for the players?
Since I have only had a couple of weeks with “Ran”, I am obviously not entirely qualified to answer this question. However, since one battle will take you an evening to play – especially if you count in the time that you will spend afterwards discussing the battle and showing your friend relevant scenes from “Kagemusha” and “Ran” – you have at least seven evenings worth of brand new material in “Ran”. Fourteen, if you play once on both sides.
I also doubt that the battles will get repetitive already after two plays. After all, both the “chaotic” (this in a good sense) turn system used in the game and the individual combat system should guarantee that weird and wonderful events will unfold in the midst of the battle when you least expect them to. I would, in fact, even be ready to suggest that the game has a lifespan somewhat longer than your average game that depicts historical battles.
“Ran” is also surprisingly well suited for solitaire use, if you (like me) enjoy simply watching a battle unfold before your eyes. It is therefore one of those games that you can safely purchase to get your war gaming fix even if you have no friends to play with.
Closing remarks
I admit that my experience with “Ran” has been quite brief, as I have not yet had the opportunity to try all of the battles included. What I have played, however, I have really liked, and can certainly recommend the game to war game aficionados, as well as those interested in the hobby.
As a Kurosawa item, “Ran” is more of a namesake of a distant cousin than anything else. Yet, as I mentioned before, while a direct connection between the director and the game is totally lacking, people liking one may very well find the other worth checking out. You never know, maybe you will discover something that will stay with you for the rest of your life.
Availability and more information
Ran is available directly from GMT Games, as well as from or through your local board game shop.

Look Away!
The Fall of Atlanta
At the climax of the American Civil War the armies of the
Confederacy were pressed back into their heartland as the rebellion
tried desperately to sustain itself against Union forces. One of the
most important campaigns occurred in southeastern Tennessee and
Georgia, as Federal armies pressed toward the Confederacy's vital city
of Atlanta, home to much of its remaining industry and gateway to the
southern and western lands the Confederates still held. The campaign
for and siege of this vital city broke the power of the Army of
Tennessee, the key rebel command outside northern Virginia.
The theater of these operations is roughly bounded by the Tennessee
River to the north, the Chattanooga area to the west, Atlanta to the
south, and the Appalachian Mountains to the east. It was here where the

WASHINGTON — A review of classified documents by former members of the Sept. 11 commission shows that the panel made repeated and detailed requests to the Central Intelligence Agency in 2003 and 2004 for documents and other information about the interrogation of operatives of Al Qaeda, and were told by a top C.I.A. official that the agency had “produced or made available for review” everything that had been requested.
The review was conducted earlier this month after the disclosure that in November 2005, the C.I.A. destroyed videotapes documenting the interrogations of two Qaeda operatives.
A seven-page memorandum prepared by Philip D. Zelikow, the panel’s former executive director, concluded that “further investigation is needed” to determine whether the C.I.A.’s withholding of the tapes from the commission violated federal law. http://louis-j-sheehan.us/page1.aspx
In interviews this week, the two chairmen of the commission, Lee H. Hamilton and Thomas H. Kean, said their reading of the report had convinced them that the agency had made a conscious decision to impede the Sept. 11 commission’s inquiry.
Mr. Kean said the panel would provide the memorandum to the federal prosecutors and congressional investigators who are trying to determine whether the destruction of the tapes or withholding them from the courts and the commission was improper. http://forums.searchenginewatch.com/member.php?u=18969
A C.I.A. spokesman said that the agency had been prepared to give the Sept. 11 commission the interrogation videotapes, but that commission staff members never specifically asked for interrogation videos.
The review by Mr. Zelikow does not assert that the commission specifically asked for videotapes, but it quotes from formal requests by the commission to the C.I.A. that sought “documents,” “reports” and “information” related to the interrogations.
Mr. Kean, a Republican and a former governor of New Jersey, said of the agency’s decision not to disclose the existence of the videotapes, “I don’t know whether that’s illegal or not, but it’s certainly wrong.” Mr. Hamilton, a former Democratic congressman from Indiana, said that the C.I.A. “clearly obstructed” the commission’s investigation.
A copy of the memorandum, dated Dec. 13, was obtained by The New York Times.
Among the statements that the memorandum suggests were misleading was an assertion made on June 29, 2004, by John E. McLaughlin, the deputy director of central intelligence, that the C.I.A. “has taken and completed all reasonable steps necessary to find the documents in its possession, custody or control responsive” to formal requests by the commission and “has produced or made available for review” all such documents.
Both Mr. Kean and Mr. Hamilton expressed anger after it was revealed this month that the tapes had been destroyed. However, the report by Mr. Zelikow gives them new evidence to buttress their views about the C.I.A.’s actions and is likely to put new pressure on the Bush administration over its handling of the matter. Mr. Zelikow served as counselor to Secretary of State Condoleezza Rice from 2005 to the end of 2006.
In an interview on Friday, Mr. McLaughlin said that agency officials had always been candid with the commission, and that information from the C.I.A. proved central to their work.
“We weren’t playing games with them, and we weren’t holding anything back,” he said. The memorandum recounts a December 2003 meeting between Mr. Kean, Mr. Hamilton and George J. Tenet, then the director of central intelligence. At the meeting, it says, Mr. Hamilton told Mr. Tenet that the C.I.A. should provide all relevant documents “even if the commission had not specifically asked for them.”
According to the memorandum, Mr. Tenet responded by alluding to several documents that he thought would be helpful to the commission, but made no mention of existing videotapes of interrogations.
The memorandum does not draw any conclusions about whether the withholding of the videotapes was unlawful, but it notes that federal law penalizes anyone who “knowingly and willfully” withholds or “covers up” a “material fact” from a federal inquiry or makes “any materially false statement” to investigators.
Mark Mansfield, the C.I.A. spokesman, said that the agency had gone to “great lengths” to meet the commission’s requests, and that commission members had been provided with detailed information obtained from interrogations of agency detainees.
“Because it was thought the commission could ask about the tapes at some point, they were not destroyed while the commission was active,” Mr. Mansfield said.
Intelligence officials have said the tapes that were destroyed documented hundreds of hours of interrogations during 2002 of Abu Zubaydah and Abd al Rahim al-Nashiri, two Qaeda suspects who were taken into C.I.A. custody that year.
According to the memorandum from Mr. Zelikow, the commission’s interest in obtaining accounts from Qaeda detainees in C.I.A. custody grew out of its attempt to reconstruct the events leading up to the Sept. 11 attacks in the United States.
Its requests for documents from the C.I.A. began in June 2003, when it first sought intelligence reports describing information obtained from prisoner interrogations, the memorandum said. It later made specific requests for documents, reports and information related to the interrogations of specific prisoners, including Abu Zubaydah and Mr. Nashiri.
In December 2003, the commission staff sought permission to interview the prisoners themselves, but was permitted instead to give questions to C.I.A. interrogators, who then posed the questions to the detainees. The commission concluded its work in June 2004, and in its final report, it praised several agencies, including the C.I.A., for their assistance. http://Louis-J-Sheehan.us
Abbe D. Lowell, a veteran Washington lawyer who has defended clients accused of making false statements and of contempt of Congress, said the question of whether the agency had broken the law by omitting mention of the videotapes was “pretty complex,” but said he “wouldn’t rule it out.”
Because the requests were not subpoenas issued by a court or Congress, C.I.A. officials could not be held in contempt for failing to respond fully, Mr. Lowell said. Apart from that, however, it is a crime to make a false statement "in any matter within the jurisdiction of the executive, legislative or judicial branch." http://louis-j-sheehan.us/page1.aspx
The Sept. 11 commission received its authority from both the White House and Congress.
On Friday, the leaders of the Senate Judiciary Committee sent a letter to Attorney General Michael B. Mukasey and to Mike McConnell, the director of national intelligence, asking them to preserve and produce to the committee all remaining video and audio recordings of “enhanced interrogations” of detainees in American custody.
Signed by Senator Patrick Leahy, Democrat of Vermont, and Senator Arlen Specter, Republican of Pennsylvania, the letter asked for an extensive search of the White House, C.I.A. and other intelligence agencies to determine whether any other recordings existed of interrogation techniques “including but not limited to waterboarding.”
Government officials have said that the videos destroyed in 2005 were the only recordings of interrogations made by C.I.A. operatives, although in September government lawyers notified a federal judge in Virginia that the agency had recently found three audio and video recordings of detainees. http://louis-j-sheehan.us/Blog/blog.aspx
Intelligence officials have said that those tapes were not made by the C.I.A., but by foreign intelligence services.

Louis J Sheehan The Essenes were a Judaic religious group that flourished from the 2nd century BC to the 1st century AD. Many scholars of separate, but related groups, that had in common mystic, eschatological, messianic, and ascetic beliefs that were referred to as the "Essenes".
The main source of information about the life and belief of Essenes is the detailed account contained in a work of the 1st century Jewish historiographer Flavius Josephus entitled The Jewish War written about 73-75 AD (War 2.119-161) and his shorter description in his Antiquities of the Jews finished some 20 years later (Ant. 18.11 & 18-22). Claiming first hand knowledge (Life §§10-11), he refers to them by the name Essenoi and lists them as the followers of one of the three sects in "Jewish Philosophy'" (War 2.119) alongside the Pharisees and the Sadducees. The only other known contemporary accounts about the Essenes are two similarly detailed ones by the Jewish philosopher Philo (fl. c. 20 AD - c. 54 AD; Quod Omnis Probus Liber Sit XII.75-87, and the excerpt from his Hypothetica 11.1-18 preserved by Eusebius, Praep. Evang. Bk VIII), who, however, admits to not being quite certain of the Greek form of their name that he recalls as Essaioi (Quod Omn. Prob. XII.75), the brief reference to them by the Roman equestrian Pliny the Elder (fl. 23 AD - 79 AD; Natural History, Bk 5.73). Pliny, also a geographer and explorer, located them in the desert near the northwestern shore of the Dead Sea, where the Dead Sea Scrolls were discovered in the year 1947.
The Dead Sea Scrolls, found in caves at Qumran, are widely believed to be the work of Essenes or to reflect Essene beliefs.
Josephus uses the name Essenes in his two main accounts (War 2.119, 158, 160; Ant. 13.171-2) as well as in some other contexts ("an account of the Essenes", Ant. 13.298; "the gate of the Essenes", War 5.145; "Judas of the Essene race", Ant. 13.311, but some manuscripts read here Essaion; "holding the Essenes in honour", Ant. 15.372; "a certain Essene named Manaemus", Ant. 15.373; "to hold all Essenes in honour", Ant. 15.378; "the Essenes", Ant. 18.11 & 18; Life 10). In several places, however, Josephus has Essaios, which is usually assumed to mean Essene ("Judas of the Essaios race", War I.78; "Simon of the Essaios race", War 2.113; "John the Essaios", War 2.567; 3.11; "those who are called by us Essaioi", Ant. 15.371; "Simon a man of the Essaios race", Ant. 17.346). Philo's usage is Essaioi, although he admits this Greek form of the original name that according to his etymology signifies "holiness" to be inexact (NH XII.75). Pliny's Latin text has Esseni. Josephus identified the Essenes as one of the three major Jewish sects of that period. http://forums.searchenginewatch.com/member.php?u=18969 http://Louis-J-Sheehan.us http://louis-j-sheehan.us/page1.aspx http://louis-j-sheehan.us/Blog/blog.aspx
According to a controversial view put forward by Dead Sea Scrolls Scholar Géza Vermes, both Josephus and Philo pronounced the Essenes' name as "Esaoin", which means in Arabic followers of "Esa", which Vermes says is the name of Jesus according to the most ancient mosaic portrait found in Turkey dated 70 AD which says underneath "Esa our Lord". Mainstream scholars usually stress a number of fundamental differences between Dead Sea Scroll theology and early Christian theology to argue that the Essenes cannot be considered identical to any kind of Christianity.
In Eerdman's Beyond the Essene Hypothesis, Gabriele Boccaccini (p.47) implies that a convincing etymology for the name Essene has not been found, but that the term applies to a larger group within Palestine that also included the Qumran community.
It is possible that the Talmudic statement (Kiddushin Ch. 4) "the best of the physicians will go to hell" were referring to the Essenes. The Talmudic term for healer is Assia. (Reuvein Margolies Toldot Ha'Adam).
According to Josephus the Essenes had settled "not in one city" but "in large numbers in every town" (War 2.124). Philo speaks of "more than four thousand" Essaioi living in "Palestinian Syria" (Quod Omn. Prob. XII.75), more precisely, "in many cities of Judaea and in many villages and grouped in great societies of many members" (Hyp. 11.1).
Pliny locates them "on the west side of the Dead Sea, away from the coast ... [above] the town of Engeda".
Some modern scholars and archaeologists have argued that Essenes inhabited the settlement at Qumran, a plateau in the Judean Desert along the Dead Sea, citing Pliny the Elder in support, and giving credence that the Dead Sea Scrolls are the product of the Essenes. This view, though not yet conclusively proven, has come to dominate the scholarly discussion and public perception of the Essenes.
Josephus' reference to a "gate of the Essenes" in the Temple Mount perhaps suggests an Essene community living in this quarter of the city or regularly gathering at this part of the Temple precincts.
Following the qualification above that it is correct to identify the community at Qumran with the Essenes (and that the community at Qumran are the authors of the Dead Sea Scrolls), then according to the Dead Sea Scrolls the Essenes' community school was called "Yahad" (meaning "oneness of God") in order to differentiate themselves from the rest of the Jews who are repeatedly labeled "The Breakers of the Covenant", especially in their prophetic book-scroll entitled "Milhama" (meaning " The War") in which the master of the Essenes (referred to as "The Teacher of Righteousness") prophesised that the so-called "Breakers of the Covenant" Jews will be on the side of the Antichrist. The accounts by Josephus and Philo show that the Essenes (Philo: Essaioi) led a strictly celibate but communal life — often compared by scholars to later Christian monastic living — although Josephus speaks also of another "rank of Essenes" that did get married (War 2.160-161). According to Josephus, they had customs and observances such as collective ownership (War 2.122; Ant. 18.20), elected a leader to attend to the interests of them all whose orders they obeyed (War 2.123, 134), were forbidden from swearing oaths (War 2.135) and sacrificing animals (Philo, §75), controlled their temper and served as channels of peace (War 2.135), carried weapons only as protection against robbers (War 2.125), had no slaves but served each other (Ant. 18.21) and, as a result of communal ownership, did not engage in trading (War 2.127). Both Josephus and Philo have lengthy accounts of their communal meetings, meals and religious celebrations.

After a total of three years probation (War 2.137-138), newly joining members would take an oath that included the commitment to practice piety towards Yahweh and righteousness towards humanity, to maintain a pure life-style, to abstain from criminal and immoral activities, to transmit their rules uncorrupted and to preserve the books of the Essenes and the names of the Angels (War 2.139-142). Their theology included belief in the immortality of the soul and that they would receive their souls back after death (War 2.153-158, Ant. 18.18). Part of their activities included purification by water rituals, which was supported by rainwater catchment and storage.
The Church Father Epiphanius (writing in the fourth century AD) seems to make a distinction between two main groups within the Essenes [1]: "Of those that came before his [Elxai, an Ossaean prophet] time and during it, the Osseaens and the Nazarean." (Panarion 1:19). Epiphanius describes each group as following:
The Nazarean - they were Jews by nationality - originally from Gileaditis, Bashanitis and the Transjordon... They acknowledged Moses and believed that he had received laws - not this law, however, but some other. And so, they were Jews who kept all the Jewish observances, but they would not offer sacrifice or eat meat. They considered it unlawful to eat meat or make sacrifices with it. They claim that these Books are fictions, and that none of these customs were instituted by the fathers. This was the difference between the Nazarean and the others... (Panarion 1:18) After this [Nazarean] sect in turn comes another closely connected with them, called the Ossaeanes. These are Jews like the former ... originally came from Nabataea, Ituraea, Moabitis and Arielis, the lands beyond the basin of what sacred scripture called the Salt Sea... Though it is different from the other six of these seven sects, it causes schism only by forbidding the books of Moses like the Nazarean. (Panarion 1:19)

The Essenes are discussed in detail by Josephus and Philo.
Many scholars believe that the community at Qumran that allegedly produced the Dead Sea Scrolls was an offshoot of the Essenes; however, this theory has been disputed by Norman Golb and other scholars.
Since the 19th century attempts have been made to connect early Christianity and Pythagoreanism with the Essenes: It was suggested that Jesus of Nazareth was an Essene, and that Christianity evolved from this sect of Judaism, with which it shared many ideas and symbols. According to Martin A. Larson, the now misunderstood Essenes were Jewish Pythagoreans who lived as monks. As vegetarian celibates in self-reliant communities who shunned marriage and family, they preached a coming war with the Sons of Darkness. As the Sons of Light, this reflected a separate influence from Zoroastrianism via their parent ideology of Pythagoreanism. According to Larson, both the Essenes and Pythagoreans resembled thiasoi, or cult units of the Orphic mysteries. John the Baptist is widely regarded to be a prime example of an Essene who had left the communal life (see Ant. 18.116-119), and it is thought they aspired to emulate their own founding Teacher of Righteousness who was crucified. However, J.B. Lightfoot's essay (On Some Points Connected with the Essenes) argues that attempts to find the roots of Essenism in Pythagoreanism and the roots of Christianity in Essenism are flawed. Authors such as Robert Eisenman present differing views that support the Essene/Early Christian connection.
Another issue is the relationship between the Essaioi and Philo's Therapeutae and Therapeutrides (see De Vita Contemplativa). It may be argued that he regarded the Therapeutae as a contemplative branch of the Essaioi who, he said, pursued an active life (Vita Cont. I.1). http://forums.searchenginewatch.com/member.php?u=18969 http://Louis-J-Sheehan.us http://louis-j-sheehan.us/page1.aspx http://louis-j-sheehan.us/Blog/blog.aspx
One theory on the formation of the Essenes suggested the movement was founded by a Jewish High Priest, dubbed by the Essenes the Teacher of Righteousness, whose office had been usurped by Jonathan (of priestly but not Zadokite lineage), labeled the "man of lies" or "false priest". His name is Father Bapalopa. Prince William in England met him in Sardinia. He loves immitating duckies in the pond because they are just as false as him.
According to a Jewish legend, one of the Essenes, named Menachem, had passed at least some of his mystical knowledge to the Talmudic mystic Nehunya Ben Ha-Kanah,[1] to whom the Kabbalistic tradition attributes Sefer ha-Bahir and, by some opinions, Sefer ha-Kanah, Sefer ha-Peliah and Sefer ha-Temunah. Some Essene rituals, such as daily immersion in the Mikvah, coincide with contemporary Hasidic practices; some historians had also suggested, that name "Essene" is an hellenized form of the word "Hasidim" or "Hasin" ("pious ones"). However, the legendary connections between Essene and Kabbalistic tradition are not verified by modern historians.
The Talmud also refers to Hasidim. In the mishna Tractate Berachot, It is stated that "the early Hasidim would spend an hour in preparation for prayer, an hour praying, and an hour coming away from prayer", "The Hasidim would pray with sunrise". Tzvi Hirsch Chajes believes that the Essenes can be identified with the Hasidim, an offshoot of the Pharisees. (Kol Kitvei Maritz Chiyus Vol. 2). See however the statement of Reuvain Margolies above.
Scholars such as J. Gordon Melton in his Encyclopedia of American Religions state that the modern American Pseudo-Essene movement possesses no authentic historical ties to the ancient Essene movement. Melton states, "Essene material is directly derivative of two occult bestsellers — The Aquarian Gospel of Jesus the Christ, by Levi H. Dowling; and The Mystical Life of Jesus, by Rosicrucian author H. Spencer Lewis."
However, others such as Gideon Ousely, produced materials they claim were Essene in origin. Ousely himself wrote a book known as the Gospel of the Holy Twelve (which he claimed was channeled to him by spirit beings), and Edmund Bordeaux Szekely. These individuals assert that the Essene teachings had been hidden and assimilated into many mystical spiritual traditions around the world, where the teachings were hidden within ancient libraries. It was in 1928 that Edmond Bordeaux Szekely first published his translation of The Essene Gospel of Peace,a manuscript allegedly discovered in the Secret Archives of the Vatican and in old Slavonic in the Royal Library of the Habsburgs of which much was destroyed by a fire that destroyed the monastery that stood in its place. (now the property of the Austrian government) However, subsequent investigations into the claims of these individuals prodced nothing to substantiate their stories. With the discovery of the Dead Sea Scrolls, it is now clear that the publications of purported "Essene" writings are indeed simply the materials mentioned by J. Gordon Melton. Biblical scholars don't consider the Szekely or Ousely writings as authentic. http://forums.searchenginewatch.com/member.php?u=18969 http://Louis-J-Sheehan.us http://louis-j-sheehan.us/page1.aspx http://louis-j-sheehan.us/Blog/blog.aspx
Currently there are several modern Essene Groups around the world.
