Beam the cat up
Packets of light that resemble Schrödinger’s hypothetical cat — existing in two states at once, both “alive” and “dead”— have been successfully teleported from one place to another. This movement of a quantum state, accomplished by a team of researchers in Japan and Australia, could be useful for sending quantum information quickly and securely. As described in the April 15 Science, the Mr. Scott-style feat destroyed the original quantum state, transmitted the information using entangled light and recreated it elsewhere. —Devin Powell


Screwy light
Light beams crimped in curls tighter than a prom queen’s hairdo may help scientists probe the structures of small molecules in pursuit of new drugs. A molecule with a left-handed structure absorbs different amounts of this “superchiral light” than its mirror-image right-handed form. This
