Scientists in the US say they are a step closer to developing materials that could render people invisible.
Researchers at the University of California in Berkeley have developed a material that can bend light around 3D objects making them "disappear".
The materials do not occur naturally but have been created on a nano scale, measured in billionths of a metre.
The team says the principles could one day be scaled up to make invisibility cloaks large enough to hide people. Read More here
