'World's smallest radio' unveiled

The world's tiniest radio is a step closer to reality.
US scientists have unveiled a detector thousands of times smaller than the diameter of a human hair that can translate radio waves into sound.

According to a University of California team, the study marks the first time that a nano-sized detector has been demonstrated in a working radio system.

Peter Burke and Chris Rutherglen incorporated the microscopic detector into a complete radio system.
