Science Alert

Scienticians in California have announced that they have developed a working invisibility cloak, just in time for the latest Star Trek movie. Previous attempts used metals which absorb some of the light and so reveal the location of the cloaked object, but the current meta-materials are totally state-of-the-art.

"The cloak's design cancels out the distortion produced by the bulge of the object underneath, bending light around it - like water around a rock - and giving the illusion of a flattened surface," says the blurb on the BBC website.
