Little mechanical “worms” offer the latest hope for early detection—and eradication—of cancer. Researchers have created tiny machines that travel through the body, find tumors that are too small to see in normal scans, and then deliver drugs to kill them. The method has worked to spot tumors in mice, but it’s still years from human use, ABC reports. More »

Sun Microsystems is moving toward connecting computer chips using lasers instead of wires, a move that could make computers 1,000 times faster. The company snagged a $44 million Pentagon contract to continue work that could also mean smaller, more energy-efficient machines. It won’t be easy, though: A Sun researcher told the New York Times the chance of success is 50%. More »

Using computer models of 50 years' worth of data, scientists confirmed warming is turning snowfall into rain, melting the packs earlier and drying up more rivers by summer. The trend threatens to trigger a crisis in the West and Southwest, reports the Washington Post . More »
