A scientist has unveiled a working radio built from carbon nanotubes that are only a few atoms across, or almost 1,000 times smaller than today's radio technology. The nanotech device is a demodulator ...

It used to be pretty keen to stuff a radio receiver into an Altoid’s tin, or to whip up a tiny crystal receiver from a razor blade and a pencil stub. But Harvard researchers have far surpassed those ...

Researchers have demonstrated an atom-based sensor that can determine the direction of an incoming radio signal, another key part for a potential atomic communications system that could be smaller and ...

Defects aren't always well-received things in scientific studies. But by causing a deliberate defect in pink diamond crystals, Harvard University researcher have created what they're calling the world ...
