Cal physicists make a radio 10,000 times thinner than a human hair

Now if you start to hear voices, it could be something that blew into your ear.

Physicists at UC Berkeley say they have produced the world's smallest radio out of a single carbon nanotube that is 10,000 times thinner than a human hair.

Professor Alex Zettl led a team that developed the minuscule filament, which can be tuned to receive AM or FM transmissions.

The first song it played? "Layla" by Derek & the Dominos. Eric Clapton's unmistakable guitar riff can be heard on a scratchy recording of the nanoradio's output posted by Zettl online.
