Two researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital have developed a living laser, in which a single cell genetically engineered to express green fluorescent protein (GFP). Before you start thinking about sharks with lasers or other science fiction creatures, this technology is used to amplify photons into nanosecond-long pulses of laser ... »
