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. Additional commentary available at The Science Blog"

    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.

    Yeah, like Shrinky Dinks this'll be a hit with the mail-order or discount store crowd before you know it.

    door latches that can be opened with a flashlight.
    Right... 'cause we all want a door that opens itself every morning when the sun comes up!

    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.

  8. Longhorn features irregular monitors by Virtual+Karma · · Score: 1, Funny

    Inside sources have confirmed that Longhorn will have a cool feature called 'irregular display'. If the use hits 'windows key + $ + ^ + F13' the screen would emit a low wave length light that will deform the monitor. You can preset the deformation patterns before hand. This revolutionary feature uses the 'plastic deformable by light' discovered recently at MIT.

    "This is a unique feature which will help us take on OS X Tiger" - Gates

    The only problem is that once deformed the monitors cannot be reverted to their orignal shape. MS is hoping that the users wont discover this bug. They might fix this in Service Pack 24 for Longhorn.

    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.
