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

Scientists discover new material that makes objects invisible to touch

You're looking at a new awesome nano-material invented that does the seemingly impossible: It hides things from touch. Just a thin layer of this amazing polymer will hide anything under it from being perceived by your sense of touch. In this photo you can see how it "absorbs" a metal cylinder. » 6/24/14 6:07pm 6/24/14 6:07pm

Japanese Men Perfect the Cloak of Invisibility Much to Japanese Women's…

Japan's been tooling around with versions of invisibility cloaks for years now, but they seem to have finally perfected it. Theoretically. By using "left-handed metamaterials" to make electromagnetic control devices, researchers can generate lenses that either reflect no light or have a perfect focal point—the end… » 4/18/08 5:00pm 4/18/08 5:00pm

Kids Invent Vanishing Nail Polish to Dodge School Rules

What would you do if your school's ban on makeup meant you couldn't show off your nail art? You'd get your chemistry set out and invent a new UV-reactive polish that was near-invisible indoors, but was bright and colorful when you're outside lessons, wouldn't you? Well, you would if you were a group of students in… » 3/24/08 12:15pm 3/24/08 12:15pm

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

Micro Bluetooth Earpiece: Smaller Than a Dime, Spytastic, Handmade

This Bluetooth headset is smaller than a dime, and small enough to be carried away by an ant. The thing is about 6mm by 5mm by 10mm. Ridica-malous! And could easily get lost in your ear. There's even a detachable buzzer, for simple communication with your poker card counting buddies, or friends across the room taking… » 8/17/06 4:34pm 8/17/06 4:34pm
