From Nevada Appeal:

WASHINGTON — For two decades, a ridge of volcanic rock 90 miles northwest of Las Vegas known as Yucca Mountain has been the sole focus of government plans to store highly radioactive nuclear waste.

Not anymore.

Despite the $13.5 billion that has been spent on the project, the Obama administration says it’s going in a different direction.

It slashed funding for Yucca Mountain in its recently announced budget.

And on Thursday, Energy Secretary Steven Chu told a Senate hearing that the Yucca Mountain site no longer was viewed as an option for storing reactor waste, brushing aside criticism from several Republican lawmakers.

From Science Daily:

ScienceDaily (Mar. 5, 2009) — Schizophrenia could be caused by faulty signalling in the brain, according to new research published in the journal Molecular Psychiatry. In the biggest study of its kind, scientists looking in detail at brain samples donated by people with the condition have identified 49 genes that work differently in the brains of schizophrenia patients compared to controls.

Many of these genes are involved in controlling cell-to-cell signalling in the brain. The study, which was carried out by researchers at Imperial College London and GlaxoSmithKline, supports the theory that abnormalities in the way in which cells 'talk' to each other are involved in the disease.

Mould Problem At France's Lascaux Cave

Paleolithic handywork: Discovered in 1940, France's Lascaux Cave has some of the world's most spectacular prehistoric cave art.

From Cosmos Magazine:

PARIS: The problem of black fungus threatening world-famous prehistoric paintings at the Lascaux Cave in southwestern France is stable, a scientist said last week.

France, criticised for its management of Lascaux, applied fungicide to the cave's walls in January 2008 in a bid to roll back patches of mould imperilling the legendary art.

Dubbed "the Sistine Chapel of prehistory," Lascaux, listed as a World Heritage Site by UNESCO, includes stunning pictures of horses, extinct bulls and ibexes, painted by unknown hands some 17,000 years ago.

From Science Daily:

ScienceDaily (Mar. 4, 2009) — NASA's Cassini spacecraft has found within Saturn's G ring an embedded moonlet that appears as a faint, moving pinprick of light. Scientists believe it is a main source of the G ring and its single ring arc.

Cassini imaging scientists analyzing images acquired over the course of about 600 days found the tiny moonlet, half a kilometer (about a third of a mile) across, embedded within a partial ring, or ring arc, previously found by Cassini in Saturn's tenuous G ring.

"Before Cassini, the G ring was the only dusty ring that was not clearly associated with a known moon, which made it odd," said Matthew Hedman, a Cassini imaging team associate at Cornell University in Ithaca, N.Y. "The discovery of this moonlet, together with other Cassini data, should help us make sense of this previously mysterious ring."

From Live Science:

For the first time, scientists have watched as the Earth’s surface “heals” itself following the disruptive jolt of an earthquake, in this case, the 2003 temblor that devastated Bam, Iran.

The fault under the city erupted in a 6.6-magnitude quake on Dec. 26 that year, leveling the town and killing more than 26,000 people. But though devastation was evident, there was no clear fault mark at the surface.

"The fault slipped maybe 2 or 3 meters [6.5 to 10 feet] at depth, but at the surface, when colleagues of mine went out, they found some cracks, but the motion on those cracks is only about up to 25 centimeters [10 inches] or less," said one of the scientists who studied the quake, Eric Fielding of Caltech. "We have some layer of material near the surface that's behaving differently from the fault at depth."

In an internal memo published on All Things D, a Microsoft search executive wrote that the company is ready to test a new search engine, codenamed “kumo.” He then outlined the problem that the new search engine is supposed to address:

“In spite of the progress made by search engines, 40% of queries go unanswered; half of queries are about searchers returning to previous tasks; and 46% of search sessions are longer than 20 minutes. These and many other learnings suggest that customers often don’t find what they need from search today.”

Here's What Killed Your 401K

From Wired News:

A year ago, it was hardly unthinkable that a math wizard like David X. Li might someday earn a Nobel Prize. After all, financial economists—even Wall Street quants—have received the Nobel in economics before, and Li's work on measuring risk has had more impact, more quickly, than previous Nobel Prize-winning contributions to the field. Today, though, as dazed bankers, politicians, regulators, and investors survey the wreckage of the biggest financial meltdown since the Great Depression, Li is probably thankful he still has a job in finance at all. Not that his achievement should be dismissed. He took a notoriously tough nut—determining correlation, or how seemingly disparate events are related—and cracked it wide open with a simple and elegant mathematical formula, one that would become ubiquitous in finance worldwide.

For five years, Li's formula, known as a Gaussian copula function, looked like an unambiguously positive breakthrough, a piece of financial technology that allowed hugely complex risks to be modeled with more ease and accuracy than ever before. With his brilliant spark of mathematical legerdemain, Li made it possible for traders to sell vast quantities of new securities, expanding financial markets to unimaginable levels.

Dolphin-Inspired Man-Made Fin Works Swimmingly

SWIM FIN INSPIRED BY DOLPHINS: Lunocet users have already hit about eight miles (13 kilometers) per hour, nearly twice as fast as Olympic Gold Medal swimmer Michael Phelps at his speediest. COURTESY OF LOMERANGER

From Scientific American:

Lunocet swimmers have already hit about eight miles per hour, almost twice the speed of Michael Phelps at his fastest.

The human body does many things well, but swimming isn't one of them. We're embarrassingly inefficient in the water, able to convert just 3 or 4 percent of our energy into forward motion. (Even with swim fins, we're only 10 to 15 percent more efficient.) But a new, dolphin-inspired fin promises to fuel the biggest change in human-powered swimming in decades, putting beyond-Olympian speeds within reach of just about anyone.

The Challenge of Pizza Box Recycling

Pizza boxes are recyclable, but grease and cheese make them less so and can cause a whole batch of recyclable material to be diverted to the trash. Image credit: Dreamstime

From Live Science:

Many people assume that pizza boxes are recyclable. In fact, most boxes have recycling symbols on them and are traditionally made from corrugated cardboard. They are, in and of themselves, recyclable.

However, what makes parts of them non-recyclable is the hot, tasty treat that comes inside them, specifically, the grease and cheese from pizza that soil the cardboard.

So there you have it, pizza boxes that are tarnished with food, or any paper product that is stained with grease or food, are not recyclable — unless you remove the tainted portions.

But why is this? And what are the implications for the general, pizza-loving public? Mmm, pizza.

From Scientific American:

Does a full moon really trigger strange behavior?

Across the centuries, many a person has uttered the phrase “There must be a full moon out there” in an attempt to explain weird happenings at night. Indeed, the Roman goddess of the moon bore a name that remains familiar to us today: Luna, prefix of the word “lunatic.” Greek philosopher Aristotle and Roman historian Pliny the Elder suggested that the brain was the “moistest” organ in the body and thereby most susceptible to the pernicious influences of the moon, which triggers the tides. Belief in the “lunar lunacy effect,” or “Transylvania effect,” as it is sometimes called, persisted in Europe through the Middle Ages, when humans were widely reputed to transmogrify into werewolves or vampires during a full moon.

ScienceDaily (Mar. 1, 2009) — A new study by scientists updating some of the findings of the Intergovernmental Panel on Climate Change (IPCC) 2001 Third Assessment Report finds that even a lower level of increase in average global temperatures due to greenhouse gas emissions could cause significant problems in five key areas of global concern.

The study, published in the Proceedings of the National Academy of Sciences, is titled "Assessing Dangerous Climate Change Through an Update of the IPCC 'Reasons for Concern."

Complexity of Spit Revealed

From Live Science:

Saliva tells a lot about a person these days, ranging from ancestry to criminal connections. But drool still holds many mysteries, including what the heck lives in it and why each of us has our own salivary signature.

A new study tries to clean this up a bit, revealing that there is a lot of bacterial diversity living in the moisture in our mouths, both within and among individuals.

From FOX News:

There was a solar eclipse earlier this month — but it wasn't visible anywhere on Earth.

Rather, a Japanese space probe in orbit around the moon got spectacular high-definition video of the sun being blocked — by the Earth, producing an otherworldly "diamond-ring" eclipse.

It may be only the third time such an eclipse has been viewed by terrestrials, human or otherwise.

An American lunar lander got a blurry snapshot of a solar eclipse in 1967, and two years later Apollo 12 astronauts got treated to the same thing on their way back from the moon.

The Big Melt

From Popular Science:

A two-year polar survey finds ice sheets melting faster than expected, and more grim news.

Less than two weeks before scientists from around the world gather in Copenhagen to issue recommendations for a new global climate-change treaty, the results from the two-year International Polar Year survey have arrived. They are not pleasant.

Here's a quick summary: The Antarctic and Greenland ice shelves are melting more quickly than we realized. Year-round Arctic sea-ice levels reached their lowest levels in 30 years, which is how long we've been keeping records. The seawater beneath Antarctica is freshening, which indicates ice melt. Global ocean currents are beginning to shift. "We're beginning to get hints of change in ocean circulation; that'll have a dramatic impact on the global climate system," IPY director David Carlson told reporters in Geneva.

Do These Mysterious Stones Mark The Site Of The Garden Of Eden?

The site has been described as 'extraordinary' and 'the most important' site in the world

From The Daily Mail:

For the old Kurdish shepherd, it was just another burning hot day in the rolling plains of eastern Turkey. Following his flock over the arid hillsides, he passed the single mulberry tree, which the locals regarded as 'sacred'. The bells on his sheep tinkled in the stillness. Then he spotted something. Crouching down, he brushed away the dust, and exposed a strange, large, oblong stone.

The man looked left and right: there were similar stone rectangles, peeping from the sands. Calling his dog to heel, the shepherd resolved to inform someone of his finds when he got back to the village. Maybe the stones were important.

From New Scientist:

AN AWESOME laser facility, built to provide fusion data for nuclear weapons simulations, will soon be used to probe the secrets of extrasolar planets.

The National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory in California was declared ready for action earlier this month. Its vital statistics reveal it to be a powerful beast: its ultraviolet lasers can deliver 500 trillion watts in a 20-nanosecond burst. That power opens up new scientific possibilities.
It can deliver 500 trillion watts in a 20-nanosecond burst - opening up new scientific possibilities

For instance, Raymond Jeanloz, an astronomer at the University of California, Berkeley, will use the device to recreate the conditions inside Jupiter and other larger planets, where pressures can be 1000 times as great as those at the centre of the Earth.

From Science Daily:

ScienceDaily (Feb. 28, 2009) — HIV is evolving rapidly to escape the human immune system, an international study led by Oxford University has shown. The findings, published in Nature, demonstrate the challenge involved in developing a vaccine for HIV that keeps pace with the changing nature of the virus.

‘The extent of the global HIV epidemic gives us a unique opportunity to examine in detail the evolutionary struggle being played out in front of us between an important virus and humans,’ says lead researcher Professor Philip Goulder of the Peter Medawar Building for Pathogen Research at Oxford University.

Writing Math On The Web

From American Scientist:

The Web would make a dandy blackboard if only we could scribble an equation.

The world wide web was invented at a physics laboratory, and the first users were scientists and engineers. You might think, therefore, that this new channel of communication would be especially well adapted to scientific discourse—that it would facilitate the expression of ideas like


or

If only it were so! The truth is, the basic protocols of the Web offer almost no support for rendering mathematics or other specialized notations such as chemical formulas. Presenting such material on a Web page often requires software add-ons or plug-ins to be installed by the author or the reader or both. Fine-tuning the display of mathematics can be a fussy and finicky process, not much easier than formatting equations with a typewriter. The results sometimes render differently—or not at all—in various Web browsers. This is a sad situation: As the Web has evolved into a thriving marketplace and playground, the scholarly and scientific community that created the technology has not been well served.
