Plastic That Changes Shape In Light
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.

I thought you couldn't light the inside your body.
I was under the assumption that was the one place the sun don't shine.

I had one of those Star Wars Speeders that fit Luke and Ben Kenobi action figures as a kid. It was all plastic. I accidentally left it on the dashboard of my mom's car during a sunny day.
Sure enough, light changed its shape irrevocably.
This could be the ultimate cure for geeks. Simply wear special plastic goggles that restrict vision (and hence computer access) if wearer does not go outside.

Personally, I'd like some self-adjusting miniblinds.

You have to appreciate the mind of a scientist.
Scientist1: Dude, look at this plastic. When it comes in contact with ultraviolet light, the plastic forms bonds with itself, causing it to change shape.
Scientist2: Awesome! If you hit it with another frequency, the proccess reverses itself.
Businessman: Hm. What sort of applications do you think this could have?
Scientist2: App-li-kay-shuns?
Scientist1: Uh, you could make toys out of it. Or... maybe like you could have it bend into... uh... medical things. For medicine.
Businessman: I'm cutting your funding.
Scientist1: WHY DON'T YOU LOVE ME?!?
