The Real Nanopod

Radios have had a huge impact on civilization in the past century. The invention of radios allowed for communications between ships and later, as an outlet for news and entertainment. More recently, they are being used in cellular phones, wireless computers, and global-positioning systems (GPS). As technology improves, the size of radios have become smaller and smaller. But how small can you get?

Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have teamed together to create the first fully functional radio... using a single carbon nanotube! This makes it the smallest radio ever made! This new technology could be useful for wireless communicaion devices as well as medical applications, such as samller hearing aids. Since the entire radio is small enough to "easily fit inside a living cell" and exists in a human's bloodstream, researchers hope to use the tool to interface with brain and muscle functions.
