I strongly dislike headlines like this (which all the crappy science news digests, like New Scientist, frequently indulge in). If light could actually be "stopped", it wouldn't be light any more. It also can't be "slowed down"; it always travels at exactly the speed of light in whatever medium it's in. OTOH, if the light's energy is absorbed by electrons, it's not "light" any more. All matter does this trick all day every day - it's not news. This sort of sentence only sows confusion in a lot of minds.
