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

Mercedes Makes an Invisible Minivan: I Hope This Becomes an Official…

Mercedes claims that its new fuel cell technology results in vehicles with no emissions, so it's as if they're invisible to the environment. And to drive this fact home, literally, they created a vehicle that was invisible to everything else. » 3/03/12 2:00pm 3/03/12 2:00pm

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

Pentagon Scientists Use 'Time Hole' to Make Events Disappear

Soldiers could one day conduct covert operations in complete secrecy, now that Pentagon-backed physicists have figured out how to mask entire events by distorting light. » 1/05/12 11:20am 1/05/12 11:20am

New Technology Tricks Water Into Thinking Your Ship Isn't There

We've already seen how future ships can be cloaked against sonar, and maybe someday even space and time. Now researchers say they can cloak the ships' wakes, tricking water itself into acting as though nothing is there. » 8/13/11 9:40am 8/13/11 9:40am

Historic Naval Gunship, Fully Cloaked

After Japan decimated the Allied Fleet in WWII's Battle of the Java Sea, the Abraham Crijnssen, a minesweeper, was ordered to escape to Australia. To avoid detection, the 186-foot boat was simply covered in branches. [HNSA via MAKE via boingboing] » 2/08/10 10:20am 2/08/10 10:20am

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

DARPA Developing Sonic Cloaking Device

DARPA, the governmental department that researches crazy things that may eventually make it into the military, is currently working on an "ultrasonic curtain". In layman's terms, it's a sonic cloaking device designed to lower noise levels by at least 30db in military vehicles. » 2/27/07 5:50pm 2/27/07 5:50pm
