Change your skin?

I had no idea we were anywhere near being able to do this, but here you are.

Artificial skin made of carbon nanotubes that scientists say can eventually be linked up to the human nervous system to give people the experience of heat, cold, and pressure. Not only will prosthetics be able to move better, but they'll also be able to start sensing like a real limb.

(Although I imagine they'll still lack the sense of motion-consciousness that lets us know the positions of our limbs without looking at them...)

Still, most exciting thing ever, right? Unfortunately, there's no time scale given for how long it will take to develop this stuff, so while we wait, let's learn more about nanotubes!
