Researchers at UC Berkeley have created a functioning radio out of a single carbon carbon nanotube 10,000 times thinner than a human hair. The nanotube vibrates with radio frequencies, and an applied electric field forces electrons to be emitted from its tip. With a battery and a pair of very sensitive headphones, you've got a microscopic Walkman. Maybe now bacteria will have something to listen to while jogging or engaging in mitosis. Read more here.
