Robot Hand Could Protect Soldiers On The Battlefield
From The Telegraph:
A robot hand that could defuse bombs, luminous goo that flows around soldiers’ moving bodies but hardens to protect them if they are hit and a uniform that conducts electricity are among the first fruits of the Ministry of Defence’s version of the Dragons’ Den.
The Centre for Defence Enterprise (CDE) in Harwell, Oxfordshire, is an initiative that aims to harness British scientific innovation for rapid use on the battlefield. Ministers also hope to temper the MoD’s reputation for laborious and costly procurements that arrive in service years after they have ceased to be useful.

New Camera System Takes The Guesswork Out Of Baseball Stats
From Popular Science:
This could be the year that baseball-stat freaks finally crack the “Derek Jeter enigma.” A panel of coaches has awarded the New York Yankees’ shortstop four of the past six Gold Glove awards for fielding excellence. That drives statisticians nuts, because nearly every statistical model ranks Jeter’s defense below average.

General Relativity: In Pretty Good Shape
If we celebrate provocative new experimental findings, we should also celebrate the careful null results (experiments that agree with existing theories) on which much of science is based. Back in October we pointed to a new analysis that used observations of gravitational lensing by large-scale structure to test Einstein’s general relativity on cosmological scales, with the intriguing result that it didn’t seem to fit. And the caveat that it probably would end up fitting once we understood things better, but it’s always important to follow up on these kinds of clues.

Astronomers Back Chile To Host World's Biggest Telescope
From The Telegraph:
For astronomers, it appears that not only does size really matter but so does an eye-opening location.
That is why an international group of four professional star gazers have banded together to back Chile's Atacama desert as home to the world's biggest telescope, to be built in 2018 based on its geographical advantages.
The high-altitude Armazones mountain in the desert in northern Chilean desert is the perfect place for the European Extremely Large Telescope (ELT) to be set up, because of skies that are cloud-free 360 nights a year, they say.

Analysis: Chocolate May Reduce Stroke Risk
Just in time for Valentine's Day, research out this week suggests eating chocolate may have a positive impact on stroke. Don't go buying too many heart boxes just yet, though, say the study authors.
A new analysis, which involved a review of three prior studies, suggests eating about a bar of chocolate a week can help cut the risk of stroke and lower the risk of death after a stroke. But the evidence is still limited, says study author, neurologist Gustavo Saposnik at St. Michael's Hospital, University of Toronto.

Cyber Warriors
When will China emerge as a military threat to the U.S.? In most respects the answer is: not anytime soon—China doesn’t even contemplate a time it might challenge America directly. But one significant threat already exists: cyberwar. Attacks—not just from China but from Russia and elsewhere—on America’s electronic networks cost millions of dollars and could in the extreme cause the collapse of financial life, the halt of most manufacturing systems, and the evaporation of all the data and knowledge stored on the Internet.

Facebook And Twitter Compete For Olympic Glory
Each Olympics brings one or two novel new events. At the 2010 Olympic Winter Games, which start in Vancouver on Friday, there is Ski Cross, in which four skiers plunge down a mountain at the same time.
Then there is an unofficial competition that we’ll call the Social Media Slalom.
That is the race between the Web’s two pre-eminent social media companies, Facebook and Twitter, to establish themselves as the most visible and viable online option for fans that want to connect directly to athletes and get the latest updates from the competition without the filter of big media.
Evolution On The March
New DNA findings show that human genetic mutations are more recent, more rapid than once thought.
Conventional wisdom holds that if you could bring back someone from 40,000 years ago, he or she would blend perfectly well with today's population.
After all, the fossils show that our ancestors were "anatomically modern" by 100,000 years ago, and by 40,000 B.C., they were creating complex tools and art.
It was easy to assume our species hadn't evolved much since then.
Now molecular biology is overturning that assumption.

Scientists Freeze Water With Heat
From Live Science:
Imagine water freezing solid even as it's heating up. Such are the bizarre tricks scientists now find water is capable of.
Popular belief contends that water freezes at 32 degrees Fahrenheit (0 degrees Celsius). Surprisingly, if water lies in a smooth bottle and is free of any dust, it can stay liquid down to minus 40 degrees F (minus 40 degrees C) in what's called "supercooled" form. The dust and rough surfaces that water is normally found in contact with in nature can serve as the kernels around which ice crystals form.

Are Robot Scientists The Future Of Laboratory Research?
From Popular Science:
There was a time when science produced robots, but a paper published recently in the Automated Experimentation Journal suggests that in the future robots will autonomously produce science. It's not just a matter of cheap labor or taking menial tasks off the hands of researchers; the authors argue that science needs to be uniform and formalized, and AI robot scientists could help us get to that point by developing their own hypotheses and carrying out experiments with minimal human input.

A Menu For Feeding 9 Billion
From New York Times:
Science Magazine has removed the pay wall from “Food Security: The Challenge of Feeding 9 Billion People.” The paper concludes, as many have before, that keeping up with humanity’s needs as numbers and appetites crest toward mid-century poses big challenges. But it expresses optimism that a sustained focus on efficiency, technology and policy innovations can do the trick. (The images above, from the paper, show how investments in water storage and other measures helped restore vegetation in a dry region in Niger.) Here’s the summary:
Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are a further threat. But the world can produce more food and can ensure that it is used more efficiently and equitably. A multifaceted and linked global strategy is needed to ensure sustainable and equitable food security, different components of which are explored here.

Google Takes On The Telecoms
From The Wall Street Journal:
Google's decision to build a gigabit-a-second broadband network serving between 50,000 and 500,000 people predictably won plaudits from the Federal Communications Commission and public interest groups. But if Google truly wants to help speed the development of universal high-speed Internet access, as it says, it will need to do much more.
After all, there isn't a huge technical challenge building a fast network. Verizon Communications already is operating one that runs at 2.5 gigabits a second, offering television, Internet and phone. The maximum Internet speed it offers is 50 megabytes per second, but it easily can turn that up. It is spending $23 billion over several years to roll out the network to pass 18 million homes in largely suburban and urban areas.

How Roman Gladiators Died
Roman gladiators took part in one of the most brutal sports in history, many dying by traumatic brain injury during their matches. A medical study published in Forensic Science International examined the skulls of deceased fighters, discovered in a gladiator graveyard from Turkey, and reveals exactly how they died and even what weapons delivered the fatal brain injury.
The graveyard was discovered by archaeologists in 1993 but this study is the result of applying modern forensic medicine, which more typically attempts to discover the cause of death by looking at human remains after a crime, to the ancient bones.

U.S. Government Wants To Track Its Citizens Through Their Cell Phones
Two years ago, when the FBI was stymied by a band of armed robbers known as the "Scarecrow Bandits" that had robbed more than 20 Texas banks, it came up with a novel method of locating the thieves.
FBI agents obtained logs from mobile phone companies corresponding to what their cellular towers had recorded at the time of a dozen different bank robberies in the Dallas area. The voluminous records showed that two phones had made calls around the time of all 12 heists, and that those phones belonged to men named Tony Hewitt and Corey Duffey. A jury eventually convicted the duo of multiple bank robbery and weapons charges.

Another Blizzard: What Happened To Global Warming?
From Time Magazine:
As the blizzard-bound residents of the mid-Atlantic region get ready to dig themselves out of the third major storm of the season, they may stop to wonder two things: Why haven't we bothered to invest in a snow blower, and what happened to climate change? After all, it stands to reason that if the world is getting warmer — and the past decade was the hottest on record — major snowstorms should become a thing of the past, like PalmPilots and majority rule in the Senate. Certainly that's what the Virginia state Republican Party thinks: the GOP aired an ad last weekend that attacked two Democratic members of Congress for supporting the 2009 carbon-cap-and-trade bill, using the recent storms to cast doubt on global warming.
