Podcast: Play in new window

Hands free video games. I’m Bob Hirshon and this is Science Update.
A 14-year-old boy is now living out every teenager’s dream: he can play a video game using only his mind. As part of his treatment for epilepsy, he had a grid that detects electrical activity implanted on the surface of his brain. Then researchers connected the grid to the video game Space Invaders. At first, the boy could play the game merely by moving his tongue and hand. But soon, he was able to play just by thinking about moving his tongue and hand. The technology could allow people with disabilities to control artificial limbs and computers.
In other news, MIT researchers have developed a liquid that stops bleeding in seconds. Made of protein fragments that knit themselves into a protective barrier, the material could save lives at accident scenes and speed up surgical procedures.
