DARPA Spends $51 Million On Matrix-Like Cyber War Firing Range
From Popular Science:
As any soldier will tell you, consistent and realistic drill forms the foundation of any successful military action. But whereas an infantryman can hone his aim at a firing range, America's Internet warriors don't have a similar venue for developing their skills at cyberwar. But DARPA hopes a $51 million network simulation, complete with computer programs that behave like human targets and adversaries, will provide the perfect arena for developing the next generation of cyberwar weapons and tactics.

The Exoplanet Explosion
The first six weeks of scientific data returned by Kepler has already turned up five exoplanets, with many more candidates waiting to be studied. (credit: NASA)From The Space Review:
Fifteen years ago, there were virtually no known planets beyond the (then nine) planets in our own solar system: just a few found by chance orbiting a pulsar. Then, in late 1995 and 1996, came the initial discovery of planets orbiting main sequence stars like the Sun. That slow trickle of discoveries became a steady stream as astronomers refined their instruments and techniques, as well as increased both the number of stars studied and their period of time observed. By the beginning of 2010 astronomers reported finding over 400 such extrasolar planets, or exoplanets.

A new class of star may recreate the conditions of the big bang in its incredibly dense core.
Pack matter tightly enough and gravity will cause it to implode into a black hole. Neutron stars were once thought to be the densest form of matter that could resist such a collapse. More recently, physicists have argued that some supernovae may leave behind even denser quark stars, in which neutrons dissolve into their constituent quarks.

Some scientists are convinced life is common in the universe, but intelligence rare. As for how long civilisations last - and stay detectable - few are willing to hazard a guess.
Two young physicists at Cornell University in upstate New York, Philip Morrison and Giuseppe Cocconi, had long been interested in gamma rays. One spring day in 1959, Cocconi posed an intriguing question: wouldn’t gamma rays be perfect for communication between the stars?
The discussion that followed led to a two-page article in the British journal Nature entitled “Searching for interstellar communications”. Sandwiched between a paper on the electronic prediction of swarming in bees and one on metabolic changes induced in red blood cells by X-rays, the duo argued that if advanced extraterrestrial civilisations existed, and wanted to communicate, they would likely use radio.

Haiti Earthquake Science: What Caused The Disaster
From The Live Science:
The major earthquake that struck Haiti Tuesday may have shocked a region unaccustomed to such temblors, but the devastating quake was not unusual in that it was caused by the same forces that generate earthquakes the world over. In this case, the shaking was triggered by much the same mechanism that shakes cities along California's San Andreas fault.
The 7.0-magnitude Haiti earthquake would be a strong, potentially destructive earthquake anywhere, but it is an unusually strong event for Haiti, with even more potential destructive impact because of the weak infrastructure of the impoverished nation.

Google Is Not The Only Internet Site Attacked By China
Google China Cyberattack Part Of Spy Campaign -- MSNBC/Washington Post
Dozens of companies, human rights groups targeted in sophisticated strike.
Computer attacks on Google that the search giant said originated in China were part of a concerted political and corporate espionage effort that exploited security flaws in e-mail attachments to sneak into the networks of major financial, defense and technology companies and research institutions in the United States, security experts said.
At least 34 companies — including Yahoo, Symantec, Adobe, Northrop Grumman and Dow Chemical — were attacked, according to congressional and industry sources. Google, which disclosed on Tuesday that hackers had penetrated the Gmail accounts of Chinese human rights advocates in the United States, Europe and China, threatened to shutter its operations in the country as a result.

Do rocks from Mars bear the tiny fossilized signs of life? Scientists who think so say they'll subject meteorites from the Red Planet to a new round of high-tech tests in hopes of adding to their evidence.
For years, only one meteorite has figured in the controversy: ALH84001, a rock that was blasted away from Mars 16 million years ago, floated through space and fell through Earth's atmosphere onto Antarctica about 13,000 years ago. Scientists reported in 1996 that the rock contained microscopic structures that looked like "nano-fossils," but skeptics said the structures could have been created by chemical rather than biological reactions.

How Winning Can Mean Losing In Poker And Life
Karen Bleier / AFP / GettyFrom Time Magazine:
You can learn a lot about gambling if you're willing to analyze 27 million hands of online poker. Don't have time for that? No worries; sociology doctoral student Kyle Siler of Cornell University has done it for you. His counterintuitive message: the more hands you win, the more money you're likely to lose — and this has implications that go well beyond a hand of cards.
Siler, whose work was published in December in the online edition of the Journal of Gambling Studies and will appear later this year in the print edition, was not interested in poker alone but in the larger idea of how humans handle risk, reward and variable payoffs. Few things offer a better way of quantifying that than gambling — and few gambling dens offer a richer pool of data than the Internet, where millions of people can play at once and transactions are easy to observe and record.

OLED Could Be Apple Tablet’s Secret Solution For E-Reading
From Gadget Lab:
An OLED display would be a pricey, but perfect, screen for e-book reading on a tablet, like the one Apple is rumored to be announcing later this month.
OLEDs are serious power drainers, but if Apple were to implement a reading mode with a black background and light-colored text, then an OLED screen would consume far less energy. That’s because OLEDs consume power differently than LCDs; they only use power when pixels are turned on. That means blacks won’t consume any energy, and such a reading mode would substantially preserve battery life, an analyst told Wired.com.

A New Theory On Why The Sun Never Swallowed The Earth
Illustration by Denis Scott / CorbisFrom Time Magazine:
When astronomers began spotting planets around distant stars in the mid-1990s, they were baffled. Many of these early discoveries involved worlds as big as Jupiter or even bigger — but they orbited their stars so tightly that their "years" were just days long. Nobody could imagine how a Jupiter or anything like it could form in such a hostile location, where the radiation of the parent star would have pushed the light gas — which makes up most of such a planet's mass — out to the farthest reaches of the solar system before it could ever coalesce.

Breezy Does It: How Wind Turbines Work
The great advantage of wind is that it is a free fuel, unlike gas, coal or oil. Britain is also a windy place, making supply relatively secure. GETTY IMAGESFrom The Independent:
Wind farms generate electricity by capturing the kinetic energy of moving air.
The three blades of each turbine turn on a horizontal axis in the wind and the movement of this drive shaft spins an electricity generator, usually via a gearbox, so that power can be fed into the National Grid.
The wind farms being planned for sites off the coast of Britain will include some of the biggest wind generators ever built, with blades up to 60m long. These offshore wind generators will stand in water that is up to 30m deep and will be up to 220m tall from the base of their foundations to the tips of the turbine blades, about 40m taller than the "Gherkin" skyscraper in London.

Now, internet radio (places like SOMA FM and Pandora) draws the material piece down to nothing (although maybe there's a greater bandwidth component if you're continuously piping music across the airwaves, instead of just once at purchase, as is the case with digital files).

The 2010s: Freakin' Awesome-With Lasers
From CBS News:
Scientists Predict Some Uncertainty, Some Unbridled Optimism, and Some Warnings to the World to Make a Course Correction.
(CBS) This article was written by Discover's Andrew Moseman and Brett Israel.
There's nothing like the round number at the start of a new decade to get everyone prognosticating (yes, we know some of you are in the crowd that says the new decade doesn't begin until 2011; OK, fine). To predict what the scientific scene will be like in 2020, the journal Nature brought in experts from 18 fields. Though the collection doesn't encapsulate the "world of tomorrow" feel of, say, the old Omni magazine, it's still packed with sunny (and scary) forecasts. Some show lingering uncertainty, some unbridled optimism, and some give warnings to the world to make a much-needed course correction. Here are five we thought were particularly telling.

Remembering The First Hydrogen Bomb Test
From Wired Science:
The long-distance scientific recordings of the blast wave from the first hydrogen bomb test have been rediscovered in a formerly classified safe at Columbia University.
On November 1, 1952, physicists created the second fusion explosion the solar system has ever known. The first occurred around 4.5 billion years ago and ignited the ongoing fusion reaction in the sun. The second, the Ivy Mike experiment, was shorter lived and detonated on an atoll in the South Pacific. This 10-megaton blast was five times more powerful than all the explosives used in World War II combined, including the nuclear-fission bombs dropped on Hiroshima and Nagasaki.

While relatively few people were looking, an unusual eclipse darkened New Year's Day.
On January 1 a giant space object blotted out our view of Epsilon Aurigae, a yellow supergiant star about 2,000 light-years from Earth. Based on studies of Epsilon Aurigae's previous eclipses, astronomers expect the star won't fully regain its bright shine until early 2011.
