Scientists Make Objects "Invisible" With a Tricky Optical Illusion

Invisibility is perhaps the most ubiquitous of sci-fi dreams: Spy movies, video games, and classic cartoons all tantalize us with this trick. Researchers at the University of Rochester still haven't unlocked the secret to that elusive invisibility cloak either, I'm afraid. But they made a very cool optical illusion… » 9/26/14 3:30pm 9/26/14 3:30pm

A Cloaking Device For Sound Will Make You Invisible To Sonar

A cloaking device that makes you appear completely invisible is still trapped in the realm of science fiction. But researchers at Duke University have successfully created a cloaking device that works with sound instead, making an object completely invisible to SONAR and other acoustic imaging techniques. » 3/12/14 6:30pm 3/12/14 6:30pm

Backing Up Is a Lot Easier When Your Car's Back Seat Is Invisible

The last time Keio University was in the news it was for a prototype wearable cloaking device developed by a team of researchers at the school. A decade later you still can't go out and buy one, but the research has inspired another brilliant use for the technology—invisible car interiors that let you see everything… » 10/04/12 9:59am 10/04/12 9:59am

British Navy Working on Developing Invisible Ships Using Metamaterials

Scientists at the Britannia Royal Navy College are working hard to make the idea of an invisible ship a reality using metamaterials that refract light in such a way that it "bends" around an object, making it appear as if it were invisible. This would only account for viewing with the naked eye however—naturally radar… » 3/03/08 8:00pm 3/03/08 8:00pm
