Irym Sgt. Bales wife: Murder charges unbelievable
CBS News National security correspondent David Martin takes a look at what drones can do, and what they MAY be able to do someday:Richard Phillips, captain of the container ship Maersk Alabama, was more than a little grateful when Seal Team Six rescued him from Somali pirates. He could have also thanked a little-known unmanned aircraft called ScanEagle. While Phillips drifted in a life boat at the mercy of three armed pirates, ScanEagles kept watch overhead. They were giving some very good information in real time to the team that ultimately saved

We are very much on the cusp, I think, of some remarkable changes in the way that we think about fighting, he said. These unmanned systems are part of that.

Vanadium dioxide might eventually become a household name because in addition to revolutionizing electronics, researchers have now discovered it can be used as an artificial muscle 1,000 times stronger than our own. Despite the unfortunate acronym of VD, vanadium dioxide is actually a wonderful material that works as an insulator at low temperatures, but suddenly becomes an efficient conductor at 67 degrees celsius. It made possible by a change in the material physical structure that can be harnessed to create movement, and eventually researchers believe VD could lead to faster and more energy-

A team of scientists at the U.S. Department of Energy Lawrence Berkeley National Laboratory have build an extremely tiny muscle motor made from vanadium dioxide that able to launch objects 50 times heavier than itself over distances f

So while the slow and methodical robots competing at the DARPA challenge this past weekend let us all breathe a collective sigh of relief that the robot rebellion is nowhere
