DOE Should Consider Enhancing Cleanup And Stabilization, National Acad
Tanks containing radioactive waste at the U.S. Department of Energy Savannah River Site, a nuclear weapons facility in South Carolina, should not necessarily be sealed as soon as the bulk of the waste has been removed, says a new congressionally mandated report from the National Academies' National Research Council. Gallery: Frag Bongs, the Most Extreme PC Cooling Systems
From oil-submerged circuit boards to liquid nitrogen cooled CPUs, check out the most extreme PC-cooling methods on the planet. Underwater Robots Work Together Without Human Input
This August in Monterey Bay, Calif., an entire fleet of undersea robots will for the first time work together without the aid of humans to observe the ocean. The mathematical system that allows the undersea robots to self-choreograph their movements in response to their environment might one day power other robotic teams that -- without human supervision -- could explore not just oceans, but deserts, rain forests and even other planets. When It Comes To Vitamins, More Is Not Always Better
Researchers funded by the Agricultural Research Service (ARS) looked into links between dietary intakes of two B vitamins--folate and vitamin B12--and mental agility among seniors. Folate and B12 are important nutrients for the development of healthy nerves and blood cells. The researchers found an interesting association among seniors aged 60 and older whose vitamin B12 blood levels were low. Aging and taking stomach-acid blockers can contribute to a gradual lessening of B12 absorption in the body. Navy Invents Real-Life Railgun
These incredibly destructive weapons aren't just for Quake anymore. In Gadget Lab. Just 30 Minutes Vigorous Exercise A Day Can Stabilize Body Mass Index
A consistently high level of physical activity from young adulthood into middle age increases the odds of maintaining a stable weight and lessens the amount of weight gained over time, according to a new analysis. People who reported at least 30 minutes of vigorous activity a day such as jogging, bicycling or swimming were more than twice as likely to maintain a stable body mass index over 20 years. Sony PFR-V1 Personal Field Speakers (aka Headphones) Look Cooler Than
Sony's new headset looks great, but doesn't perform very well for most kinds of music. Scientists Develop Artwork That Changes To Suit Your Mood
Computer scientists from Bath and Boston have developed electronic artwork that changes to match the mood of the person who is looking at it.Using images collected through a Web cam, special software recognizes eight key facial features that characterize the emotional state of the person viewing the artwork.It then adapts the colors and brush strokes of the digital artwork to suit the changing mood of the viewer. Sim City: Terrortown
How real is the cyberterrorism threat? A crisis simulation puts a worst-case scenario in perspective. By Chris Suellentrop from Wired magazine. UNC Scientists Develop Promising New X-ray Device Using Carbon Nanotub
Scientists at the University of North Carolina at Chapel Hill and a UNC start-up company, Xintek, Inc., have invented a new X-ray device based on carbon nanotubes that emits a scanning X-ray beam composed of multiple smaller beams while also remaining stationary.
