Magnetics researchers at the National Institute of Standards and Technology (NIST) colored lots of eggs recently. Bunnies and children might find the eggs a bit small—in fact, too small to see without a microscope. But these "eggcentric" nanomagnets have another practical use, suggesting strategies for making future low-power computer memories. For a study described in a new paper,* NIST researchers used electron-beam lithography to make thousands of nickel-iron magnets, each about 200 nanometers (billionths of a meter) in diameter. Each magnet is ordinarily shaped like ...

Is a College Education Worth the Investment? Recent headlines show improved unemployment numbers and hint at a recovering economy. But millions of new college graduates still face bleak job prospects after graduation. It's no secret: most college grads are saddled with student debt. The nation's total student loan debt, by some estimates, exceeds $830 billion - more than the nation's total credit card debt. When such debt is compared to the average salary for recent college grads, one must ask: Is an expensive college degree always worth the investment? Given how difficult ...

Army's New Brain Injury Test: "Breakthrough" or Bomb? Can one simple blood test diagnose a brain injury before symptoms of the brain injury show themselves to medical practitioners?

Male peacock tail plumage and courtship antics likely influence their success at attracting and mating with females, according to recent Queen's University research. Roz Dakin and Robert Montgomerie have found that natural variation in the number of eyespots on a peacock's tail does not impact a male's mating success. However, peacocks whose tails are clipped to considerably reduce the number of eyespots are less successful at mating. Female rejection of males with substantially fewer eyespots on their tails may have a number of explanations, including the perceived ...
