Researchers have been using graphene to develop an assortment of technologically advanced things for a while, from camera sensors and contact lenses all the way to frickin' lasers. That's why it's not a surprise to see a group of engineers from Columbia University create the world's smallest FM transmitter using the atom-thick material. The end product isn't just for show, either, as it can pump tunes over the airwaves to a regular FM radio -- the team even used Gangnam Style to prove that it works. As interesting as the teensy transmitter is, the engineers have no plans to build a radio for ants, and this is merely part of a larger study into nano-electromechanical systems. Now all we need is for someone to make a tiny violin and a pair of tweezers small enough for us to play.
