Cloaking may not be just for Romulans anymore. A new theoretical development appears to be paving the way for invisibility technology that was formerly in the domain of science-fiction. The concept, proposed by two scientists at the Univ. of Pennsylvania, involves using plasmons, which are odd, wave-like excitations that bounce off the surface of metals. Potentially, the plasmons could be manipulated to cancel out visible light or radiation coming from objects. Read more at LiveScience.com(1).
