The Bad Astronomer writes "The asteroid 2011 AG5 is 140 meters across: football-stadium-sized. Its orbit isn't nailed down well enough to say yet, but using what's currently known, there's a 1 in 625 chance it will impact the Earth in 2040. It's behind the Sun until September 2013, and more observations taken then will probably reduce the odds of impact to something close to 0. But does it make sense to wait until then to start investigating a mission to deflect it away our planet? Astronomers are debating this right now, and what they conclude may pave the way for how we deal with an asteroid threat in the future."

greenrainbow writes "According to scientists, there are mussels at the bottom of the ocean that are efficiently converting hydrogen into energy in their very own, nature-made hydrogen fuel cells (abstract). The mussels were found near hydrothermal vents on the ocean floor and have onboard symbiotic bacteria that convert hydrogen into energy. With this discovery, researchers might be able to clone the hydrogen eating bacteria to create all-natural hydrogen fuel cells to power things other than sea life."

destinyland writes "A technology CEO sees game artificial intelligence as the key to a revolution in education, predicting a synergy where games create smarter humans who then create smarter games. Citing lessons drawn from Neal Stephenson's The Diamond Age, Alex Peake, founder of Primer Labs, sees the possibility of a self-fueling feedback loop which creates 'a Moore's law for artificial intelligence,' with accelerating returns ultimately generating the best possible education outcomes. 'What the computer taught me was that there was real muggle magic ...' writes Peake, adding 'Once we begin relying on AI mentors for our children and we get those mentors increasing in sophistication at an exponential rate, we're dipping our toe into symbiosis between humans and the AI that shape them.'"

Med-trump writes "Neanderthals, whose ancestors left Africa about 400,000 to 800,000 years ago, evolved in what is now mainly France, Spain, Germany and Russia, and are thought to have lived until about 30,000 years ago. Now scientists have identified a piece of Neanderthal DNA (called a haplotype) in the human X chromosome and conclude that this haplotype is present because of mating between our ancestors and Neanderthals. The study was published in the latest issue of the journal Molecular Biology and Evolution."

autospa writes with an intriguing story found at Nature about direct electrical stimulation's effect on the brain. By applying low levels of electrical current to different parts of the brain via electrodes placed on the scalp, University of New Mexico researchers claim to have documented some significant changes in brain activity, which vary depending on the part of the brain targeted. Gamers, take note: in one experiment in which volunteers were recorded while playing a video war game, "those receiving 2 milliamps to the scalp (about one-five-hundredth the amount drawn by a 100-watt light bulb) showed twice as much improvement in the game after a short amount of training as those receiving one-twentieth the amount of current." The idea of affecting the brain by electric stimulation isn't new; but the battery-powered, non-invasive variety naturally leads some people to consider rolling their own.

HansonMB writes "Facing the likelihood of state budget cuts that would eliminate $15 million for library and reading programs – and, apparently, create a future in which people no longer read things on paper – the city of Newport Beach is considering turning its first library into a community center that would host all the same amenities – except for the books." The library has been inundated with hate-mail as people around the country have learned of their idea, and they hastened to clarify that no final decision has been made; carting books in as needed from other locations was always part of the plan. Whether or not they go through with it, efforts are underway elsewhere to create a massive, public digital library, spurred in part by the recent ruling against Google Books.

schliz writes "Online dating company Gotham Dating Partners has announced plans to create profiles for non-registered individuals based on publicly available information from social networking sites, e-mail registries, mailing lists, marketing surveys, government census records, real estate listings and business websites. Although the Australian Privacy Commissioner has warned that the automatic creation of identifiable profiles of individuals without their knowledge is 'not good privacy practice,' Gotham Dating Partners does not expect to face any privacy issues from the move, which is expected to boost its membership from 6.5 million to 340 million worldwide."

aesoteric writes "An EMC test engineer has pleaded guilty to stealing almost $1 million worth of kit from his employer. He reportedly stole the unspecified goods from the storage giant's North Carolina factory using 'a small bag' to smuggle the kit out before selling it on the internet under a pseudonym."

MMBK writes "It's the ultimate salvagepunk experiment, building a telegraph out of things found in the woods. From the article: 'During the summer of 2009, artist Jamie O’Shea of the organization Substitute Materials set out to test whether or not electronic communication could have been built at any time in history with the proper knowledge, and with only tools and materials found in the wilderness of New Jersey.'"
