Mathematician Designs a Time Cloak That Uses Just Light and Mirrors

You know what the futurists are always saying: Time cloaks are so cool but they're so complicated. And it's true! What were you expecting from a device that literally hides moments in time? A Northwestern mathematician has just shown, though, it doesn't have to be quite so hard after all. » 8/14/13 12:20pm 8/14/13 12:20pm

A Time Cloak Made from Lasers Can Erase Data from History

Time cloaks are so much cooler than invisibility cloaks because they use freaking time to hide things, not silly dumb vision tricks. This new method of using a time cloak is the first that can cloak data at rapid rates. It might change security altogether. » 6/05/13 10:30pm 6/05/13 10:30pm

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

Scientists Completely "Cloak" Three-Dimensional Objects for the First…

Hiding behind a life-sized negative of yourself won't actually turn you invisible. But researchers at the University of Texas at Austin have figured out how to use that same idea to make real-world objects vanish when shot with microwave energy. » 1/26/12 2:00am 1/26/12 2:00am

Scientists Invent Cloak of Silence, Still Working on Cone Version

Invisibility cloaks have been making headlines recently, whether underwater, on Jeeps, or in labs. They're great for keeping you out of sight, but what if you want to move silently too? There's the newly developed "silence cloak." » 12/23/11 12:40am 12/23/11 12:40am

These Soldiers Don't Need Invisibility Technology

Watch very closely as the camera pans around this landscape and try to locate the horde of soldiers—twenty? thirty?—hiding in plain sight. Apparently, some people in the military need no stinking magic cloaking technology to become invisible. [Thanks Karl!] » 2/06/11 1:00am 2/06/11 1:00am

Scientists Thwart the Invisibility Cloak (Again)

Invisibility cloaks don't even exist (unless you're Liu Bolin), yet scientists keep trying to ruin the fun. C'mon, guys. Wouldn't it be more enjoyable to figure out the awesome uses for one instead of trying to get us all caught? » 12/05/09 8:00pm 12/05/09 8:00pm
