AnonymousHack writes "Swiss and MIT researchers have developed a wearable kit that will capture your every move for mapping onto a virtual character. It's almost as accurate as the camera-based motion capture used in studios to develop games. The team have recorded people's movements in completely new locations — like driving a car — previously out of reach. There is even a video of it in action."Read more of this storyat Slashdot.
HeavensBlade23 sends in an article from the German site Spiegel Online about mounting evidence that nuclear radiation may not be as deadly as has been widely believed. The article cites studies by German, US, and Japanese researchers concluding, for example, that fewer than 800 deaths are attributable to the after-effects of radiation in over 86,500 survivors of the Hiroshima bombing. Other surprisingly low death rates are reported in studies of Chernobyl and of a secret Siberian town called Mayak, devoted to producing plutonium, that was abandoned after a nuclear accident in 1957.Read more of this storyat Slashdot.
ZDOne writes "ZDNet UK has put together a list of some of the biggest obstacles preventing information technology from achieving its true potential, in terms of development and progress. Microsoft's stranglehold on the desktop makes the list, as does the chip-makers' obsession with speed. 'There is more to computing than processor speed -- a point which can be easily proven by comparing a two-year-old PC running Linux with a new PC buckling under the weight of Vista. Shrinking the manufacturing process to enable greater speed has proven essential, but it's running out of magic ... What about smarter ways of tagging data? The semantic web initiative runs along these sorts of lines, so where is the hardware-based equivalent?'"Read more of this storyat Slashdot.
Invisible Pink Unicorn writes "One of the most comprehensive analyses of genetic variation ever undertaken supports the theory that the ancestors of modern native peoples throughout the Americas came from a single source in East Asia across a northwest land bridge some 12,000 years ago. One particular discovery is of a 'unique genetic variant widespread in natives across both continents — suggesting that the first humans in the Americas came in a single migration or multiple waves from a single source, not in waves of migrations from different sources.' The full article is available online from PLoS."Read more of this storyat Slashdot.
An anonymous reader writes "Scientists can't figure out why these rocks — weighing up to several hundred pounds each — slide across a dry lake bed. The leading theory proposes that wind moves the rocks after a rain when the lake bed consists of soft and very slippery mud.Read more of this storyat Slashdot.
Iddo Genuth writes "HP and Crospon have developed a skin patch employing microneedles that barely penetrate the skin. The microneedles can replace conventional injections and deliver drugs through the skin without causing any pain. The skin patch technology also enables delivery of several drugs by one patch and the control of dosage and of administration time for each drug. It has the potential to be safer and more efficient than injections."Read more of this storyat Slashdot.
Invisible Pink Unicorn writes "A computer model simulation developed at UC Riverside has predicted that in late 2007 to early 2008, the interplanetary spacecraft Voyager 2 will cross the termination shock, the spherical shell around the solar system that marks where the solar wind slows down to subsonic speed. At the termination shock, located at 7-8.5 billion miles from the sun, the solar wind is decelerated to less than the speed of sound. The boundary of the termination shock is not fixed, however, but wobbly, fluctuating in both time and distance from the sun, depending on solar activity. Because of this fluctuation, the spacecraft is also predicted to cross the boundary again in middle 2008. The article abstract is available from The Astrophysical Journal."Read more of this storyat Slashdot.
StonyandCher writes to mention that a University of Ottawa grad student is creating a search engine for visual images that will be powered by a system mapped from the human brain. "Woodbeck said he has already created a prototype of the search engine based on his patent, which apes the way the brain processes visual information and tries to take advantage of currently-available graphics processing capabilities in PCs. 'The brain is very parallel. There's lots of things going on at once,' he said. 'Graphics processors are also very parallel, so it's a case of almost mapping the brain onto graphics processors, getting them to process visual information more effectively.'"Read more of this storyat Slashdot.
OriginalArlen writes "The BBC has a first look at NASA's initial concepts for a manned Mars mission, currently penciled in for 2031. The main vehicle would be assembled on orbit over three or four launches of the planned Ares V heavy lift rocket. New abilities to repair, replace, and even produce replacement parts will be needed to provide enough self-sufficiency for a 30 months mission, including 16 months on the surface. The presentation was apparently delivered at a meeting of the Lunar Exploration Management Group, although there's nothing on their site yet."Read more of this storyat Slashdot.
coondoggie writes "Boeing and the US Air Force today said they have tested new technology that for the first time will let military aircraft launch bombs from aircraft moving at supersonic speeds. Researchers from Boeing Phantom Works and the Air Force Research Laboratory used a rocket sled in combination with what researchers called "active flow control" to successfully release a smart bomb known as MK-82 Joint Direct Attack Munition Standard Test Vehicle (JDAM) at a speed of about Mach 2 from a weapons bay with a size approximating that of the U.S. Air Force B-1 bomber, Boeing said. Active flow control is a tandem array of microjets upstream of the weapons bay that,when fired reduces the unsteady pressures inside the bay and modifies the flow outside to ensure the JDAM munition travels out of the bay correctly."Read more of this storyat Slashdot.
Hugh Pickens writes "Scientific American has an interesting article on the secret to raising smart kids that says that more than 30 years of scientific investigation suggests that an overemphasis on intellect or talent leaves people vulnerable to failure, fearful of challenges and unwilling to remedy their shortcomings. In particular, attributing poor performance to a lack of ability depresses motivation more than does the belief that lack of effort is to blame. One theory of what separates the two general classes of learners, helpless versus mastery-oriented, is that these different types of students not only explain their failures differently, but they also hold different "theories" of intelligence. The helpless ones believe that intelligence is a fixed trait: you have only a certain amount. Mistakes crack their self-confidence because they attribute errors to a lack of ability, which they feel powerless to change. Mastery-oriented children think intelligence is malleable and can be developed through education and hard work. Challenges are energizing rather than intimidating offering opportunities to learn."Read more of this storyat Slashdot.
Riding with Robots writes "For the past two years, Europe's Venus Express orbiter has been studying Earth's planetary neighbor up close. Today, mission scientists have released a new collection of findings and amazing images. They include evidence of lightning and other results that flesh out a portrait of a planet that is in many ways like ours, and in other ways hellishly different, such as surface temperatures over 400C and air pressure a hundred times that on Earth. The article lists seven papers that will be published today in Nature."Read more of this storyat Slashdot.
Markmarkmark writes "Wired is reporting that all NASA JPL scientists must 'voluntarily' (or be fired) sign a document giving the government the right to investigate their personal lives and history 'without limit'. According to the Union of Concerned Scientists this includes snooping into sexual orientation, mental & physical health as well as credit history and 'personality conflict'. 28 senior NASA scientists and engineers, including Mars Rover team members, refused to sign by the deadline and are now subject to being fired despite a decade or more of exemplary service. None of them even work on anything classified or defense related. They are suing the government and documenting their fight for their jobs and right to personal privacy."Read more of this storyat Slashdot.
SoyChemist writes "Scientists from Korea and the Czech Republic have discovered new drugs that can counteract the chemical overload caused by nerve gas. All of the experimental medications belong to a family of chemicals called oximes. Those molecules reactivate the enzyme that is damaged by the chemical weapons. Last year, the FDA approved the first combined atropine and oxime auto-injector for use by emergency personnel. Israel has been providing them to their citizens since the first Gulf War."Read more of this storyat Slashdot.
