NASA has its sights on launching rockets into space with lasers. "What if..." they're wondering, "shuttles could be sent up using laser beams to heat their fuel from the ground?" Biophysicists in Japan have had a similar idea. They've successfully used lasers to launch genes inside living creatures, with a little help from nanotechnology. If this works in humans, future battles with cancer may be fought by remote control
