From Science Daily:

Science Daily (Feb. 1, 2010) — A 10 percent drop in water vapor ten miles above Earth's surface has had a big impact on global warming, say researchers in a study published online January 28 in the journal Science. The findings might help explain why global surface temperatures have not risen as fast in the last ten years as they did in the 1980s and 1990s.

How To Fall 35,000 Feet—And Survive

From Popular Mechanics:

You're six miles up, alone and falling without a parachute. Though the odds are long, a small number of people have found themselves in similar situations—and lived to tell the tale. Here's PM's 120-mph, 35,000-ft, 3-minutes-to-impact survival guide.

You have a late night and an early flight. Not long after takeoff, you drift to sleep. Suddenly, you’re wide awake. There’s cold air rushing everywhere, and sound. Intense, horrible sound. Where am I?, you think. Where’s the plane?

You’re 6 miles up. You’re alone. You’re falling.

Things are bad. But now’s the time to focus on the good news. (Yes, it goes beyond surviving the destruction of your aircraft.) Although gravity is against you, another force is working in your favor: time. Believe it or not, you’re better off up here than if you’d slipped from the balcony of your high-rise hotel room after one too many drinks last night.

The Brain: What Is The Speed Of Thought?

From Discover Magazine:

Faster than a bird and slower than sound. But that may be besides the point: Efficiency and timing seem to be more important anyway.

When Samuel Morse established the first commercial telegraph, in 1844, he dramatically changed our expectations about the pace of life. One of the first telegraph messages came from that year’s Democratic National Convention in Baltimore, where the delegates had picked Senator Silas Wright as their vice presidential nominee. The president of the convention telegraphed Wright in Washington, D.C., to see if he would accept. Wright immediately wired back: No. Incredulous that a message could fly almost instantly down a wire, the delegates adjourned and sent a flesh-and-blood committee by train to confirm Wright’s response—which was, of course, the same. From such beginnings came today’s high-speed, networked society.

Charting The Winners And Losers In Obama’s Science Budget

From Wired Science:

President Obama’s administration revealed its new budget Monday, and it increases funding for nearly all areas of science.

The largest raise went to the National Institutes of Health, which added $1 billion dollars to an already hefty budget. With the boost, the NIH would receive $32.1 billion in total funding. Only the Centers for Disease Control would receive less money than last year, although the cut is small. NASA, the Department of Energy’s Office of Science, and the National Science Foundation, as well as smaller research efforts at the National Institute for Standards and Technology and Department of Agriculture, would also get bumps.

From Discover Magazine:

Quantum computing—using individual atoms as information carriers—could transform the way we study the world, solving problems that would take many human lifetimes for today’s supercomputers in a matter of days. Unlike conventional computers, which store each piece of data as a single value (either zero or one), quantum processors can take on multiple values simultaneously, which is why they are so efficient. Or rather why they would be, if we could figure out how to build them. So engineers in the field are abuzz about two major advances toward the creation of a practical quantum computer.

Spies And Climate Change

'Climate Emails Hacked By Spies' -- The Independent

Interception bore hallmarks of foreign intelligence agency, says expert.

A highly sophisticated hacking operation that led to the leaking of hundreds of emails from the Climatic Research Unit in East Anglia was probably carried out by a foreign intelligence agency, according to the Government's former chief scientist. Sir David King, who was Tony Blair's chief scientific adviser for seven years until 2007, said that the hacking and selective leaking of the unit's emails, going back 13 years, bore all the hallmarks of a co-ordinated intelligence operation – especially given their release just before the Copenhagen climate conference in December.

China Leading Global Race To Make Clean Energy

As China takes the lead on wind turbines, above, and solar panels, President Obama is calling for American industry to step up. Shiho Fukada for The New York Times

From The New York Times:

TIANJIN, China — China vaulted past competitors in Denmark, Germany, Spain and the United States last year to become the world’s largest maker of wind turbines, and is poised to expand even further this year.

China has also leapfrogged the West in the last two years to emerge as the world’s largest manufacturer of solar panels. And the country is pushing equally hard to build nuclear reactors and the most efficient types of coal power plants.

These efforts to dominate renewable energy technologies raise the prospect that the West may someday trade its dependence on oil from the Mideast for a reliance on solar panels, wind turbines and other gear manufactured in China.

From The Washington Post:

NASA's grand plan to return to the moon, built on President George W. Bush's vision of an ambitious new chapter in space exploration, is about to vanish with hardly a whimper. With the release Monday of President Obama's budget request, NASA will finally get the new administration's marching orders, and there won't be anything in there about flying to the moon.

The budget numbers will show that the administration effectively plans to kill the Constellation program that called for a return to the moon by 2020. The budget, expected to increase slightly over the current $18.7 billion, is also a death knell for the Ares 1 rocket, NASA's planned successor to the space shuttle. The agency has spent billions developing the rocket, which is still years from its first scheduled crew flight.

I, Virus: Why You're Only Half Human

Part of our DNA (Image: Mehau Kulyk/SPL/Getty)

From New Scientist:

WHEN, in 2001, the human genome was sequenced for the first time, we were confronted by several surprises. One was the sheer lack of genes: where we had anticipated perhaps 100,000 there were actually as few as 20,000. A bigger surprise came from analysis of the genetic sequences, which revealed that these genes made up a mere 1.5 per cent of the genome. This is dwarfed by DNA deriving from viruses, which amounts to roughly 9 per cent.

On top of that, huge chunks of the genome are made up of mysterious virus-like entities called retrotransposons, pieces of selfish DNA that appear to serve no function other than to make copies of themselves. These account for no less than 34 per cent of our genome.

Archaeology In Jerusalem: Digging Up Trouble

Contested ground Workers at a site in East Jerusalem have uncovered bones and other evidence of early habitation. Yoray Liberman — Getty for TIME

From Time Magazine:

The Jerusalem syndrome is a psychological disorder in which a visit to the holy city triggers delusional and obsessive religious fantasies. In its extreme variety, people wander the lanes of the Old City believing they are biblical characters; John the Baptist, say, or a brawny Samson, sprung back to life.

Archaeologists in the Holy Land like to joke that their profession is vulnerable to a milder form of the syndrome. When scientists find a cracked, oversize skull in the Valley of Elah, it can be hard to resist the thought that it might have belonged to Goliath, or to imagine, while excavating the cellars of a Byzantine church, that the discovery of a few wooden splinters might be part of the cross on which Christ died. This milder malady is nothing new. In the mid-19th century, British explorers who came to Jerusalem with a shovel in one hand and a Bible in the other used the holy book as a sort of treasure map in the search for proof of Christianity's origins.

From Science Daily:

Science Daily (Jan. 30, 2010) — A new experiment that reproduces the magnetic fields of the Earth and other planets has yielded its first significant results. The findings confirm that its unique approach has some potential to be developed as a new way of creating a power-producing plant based on nuclear fusion -- the process that generates the sun's prodigious output of energy.

Fusion has been a cherished goal of physicists and energy researchers for more than 50 years. That's because it offers the possibility of nearly endless supplies of energy with no carbon emissions and far less radioactive waste than that produced by today's nuclear plants, which are based on fission, the splitting of atoms (the opposite of fusion, which involves fusing two atoms together). But developing a fusion reactor that produces a net output of energy has proved to be more challenging than initially thought.

How Much Sleep Do I Need?

From Live Science/Tech Media:

Scientists can't say exactly how much sleep each person needs, but there are some guidelines. And you should know that serious lack of sleep — less than six or seven hours a night — has been associated with increased risks of high blood pressure, hypertension, obesity, diabetes and cancer.

But much about sleep's role in health, and the how much sleep each person needs, remains a mystery. Some studies have suggested that older people need less sleep. Research reported in the journal Current Biology in 2008 found that when asked to stay in bed for 16 hours in the dark each day for several days, younger people participants slept 9 hours on average while older people got 7.5 hours of shut-eye.

Supermassive black holes, dark matter and stars are some of the contributors to the overall entropy of the universe, which is a measure of the irreversible processes occurring throughout.

From PC World:

The new Apple iPad's color multitouch display will clobber -- but not kill -- the blossoming e-reader market, which includes Amazon.com's Kindle, the Sony Reader and other devices that use gray-scale displays and slower interfaces, some analysts said.

The sale of games is increasing by 20% a year but, outside the gaming press, we're not really talking about them.

Cockroaches are capable of instinctive muscle action that doesn’t require reflex control. For the most part, they don’t have to think about running--they just do it. Researchers at Oregon State University are trying to apply what they are learning from the bodies of these tiny insects to create running robots that can effortlessly cover rough ground.
