Silicon wafer in chip plant, Intel Intel makes light work for chips  - BBC  The speed data travels around the net could get a boost thanks to research by chip giant Intel. Scientists at the company have found a way to use silicon to move light around rather than just electrons. The breakthrough could make it much easier to use light inside computer processors as well as make it cheaper to build fast computer networks. Intel said that the technology should start showing up in devices by the end of the decade. "This is a significant step toward building optical devices that move data around inside a computer at the speed of light."
Ohio State Ready To Go Robo In Desert Trek - SpaceDaily  At 2.5 tons and 9 feet high, the truck that Ohio State University engineers are about to race across the Mojave Desert could literally crush the competition. TerraMax, Ohio State's entry in the DARPA Grand Challenge autonomous race. And it would do so without a driver. Of course, the truck won't be squashing its rivals -- the purpose of the competition is to design vehicles that can drive autonomously and avoid obstacles, rather than run them over. With no human intervention and only global positioning system and local sensing data to guide it, the truck must find its way across the desert as part of the Defense Advanced Research Projects Agency (DARPA) Grand Challenge, March 8-13. 

Chemistry Puts New Sparkle In Diamonds - SpaceDaily  Diamonds are getting bigger, more colorful and cheaper, thanks to chemistry. The diamond-making business has been around for years and although synthetic diamonds had many important uses, including saw blades, drill bits and exfoliants, they were tiny and not gem quality. Only recently has chemistry been able to grow large, gem quality stones at approximately one-third the price of mined diamonds, says C&EN. Companies such as Gemesis in Florida and Apollo Diamond in Boston are now creating lab-grown diamonds that can be produced to more than a carat in size and are virtually indistinguishable from their mined counterparts.
