For the first time, physicists have devised a way to make visible light travel in the opposite direction than it normally bends when passing from one material to another, like from air through water or glass.

For the first time, physicists have devised a way to make visible light travel in the opposite direction than it normally bends when passing from one material to another, like from air through water or glass. The phenomenon, known as negative refraction, could, in principle, be used to construct optical microscopes for imaging things as small as molecules, and even to create cloaking devices for rendering...
