UC Berkeley creates radio out of a nanotube

University of California at Berkeley's nanoradio might be a 100 billion times smaller than the first commercial radios, but it plays the hits that never die.

Alex Zettl, a professor of physics at the university, has made a radio out of a single carbon nanotube that's about 10,000 times thinner than a human hair. It runs on batteries and you need headphones to use it, but it tunes in stations on the FM dial. Read more
