The Mother Superior in the Sound of Music asked: "how do you hold a moonbeam in your hand?" The answer to this immortal question is probably still "you can't"; but physicists may have solved the equally ponderable conundrum of how to hold a rainbow.

"Friendly forces will be able to see through [one of these new materials] and shoot through it, but hostile forces will not." Such shields will also have "the ability to 'self-heal' if necessary...."

Everyone has seen a prism bend light. Now researchers have constructed a material that bends visible light in the opposite way. The odd effect, known as negative refraction, is similar to what is needed in far-out proposals for creating a cloak of invisibility.
