1460569 story Plastic That Changes Shape In Light 123 Posted by Zonk on Friday April 15, 2005 @06:47PM from the i'm-liquid-metal dept. JLavezzo writes "Picture a flower that opens when facing the sunlight. In work that mimics that sensitivity to light, MIT Engineer Robert Langer and his German colleagues have created the first plastics that can be deformed and temporarily fixed into shape by light. This material could one day lead to medical devices that build themselves inside a patient's body, or door latches that can be opened with a flashlight.
