What if you could hide something in plain sight? It could be possible using cloaking technologies.

Engineers believe that continued advances in creating ever-more exotic and sophisticated human-made materials will greatly improve their ability to control light at will.

There's always a lot of fuss about getting other things to go as fast or faster than the speed of light. But what about changing the speed of light? Is there anything useful we could do by slowing light down rather than speeding things up?

The science of stealth has long been a matter of fading into already obscure environments—the night sky, say, or the deep sea. But engineers are now developing materials that could hide anything in plain sight. Instead of bending light inward, like water and glass do, these optical metamaterials bend it outward, guiding photons around an object like river water around a stone.

Today in crazy tricks of physics, a few researchers over at the University of Southampton in the U.K. have theorized that metamaterials ought to be able to generate a wholly new kind of force--something akin to the adhesive force created by gecko toes--that can be turned on and off optically with the throwing of a switch. That force ought to be strong enough to overcome the force of Earth’s gravity, opening the door to a range of potential applications--if and when the actual force is found.
