World's smallest radio receiver has building blocks the size of 2 atoms


Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences have made the world's smallest radio receiver - built out of an assembly of atomic-scale defects in pink diamonds.

This tiny radio -- whose building blocks are the size of two atoms -- can withstand extremely harsh environments and is biocompatible, meaning it could work anywhere from a probe on Venus to a pacemaker in a human heart.
