Scientists close in on cloaking device

LOS ANGELES - A cloaking device that scientists have been working on for years appears to be one step closer to becoming a reality, according to Scientific American .

In a paper published in Science magazine , scientists from Duke University say they have come up with a new type of device that is significantly more sophisticated at cloaking an object from visible light.

The device is made from a light-bending composite material that can send electromagnetic waves around an object and reconnect them on the other side.

Fictional cloaking devices have been featured in movies, but some believe that a viable invisibility shield like the ones in Star Trek could emerge from labs in a few decades.
