After two years of rapid scientific progress, the U.S. Army is getting closer to mastering man-made "meta-materials" that can bend light around an object, according to one military researcher.
Okay, seriously. According to Dr. Richard Hammond from the Army Research Office, the military is two or three years away from being able to manufacture devices using meta-materials that allow "unprecedented extreme control over the flow of light." And not just that: in theory the materials could deflect radar and other sensors, too.
