We're another step closer to the invisibility cloak

We're another step closer to the invisibility cloak: "A functional invisibility cloak is one of those things that physicists keep chasing, and every six months or so we see an update that brings us one step closer to being able to sneak around without being seen. Today's major breakthrough comes from an undergraduate student at the University of St Andrews who figured out how to get around the fundamental problem of light taking too long to travel around the hidden object."
