We're another step closer to the invisibility cloak

A functional invisibility cloak is one of those things that physicists keep chasing, and every six months or so we see an update that brings us one step closer to being able to sneak around without being seen. Today's major breakthrough comes from an undergraduate student at the University of St Andrews who figured… » 8/11/11 9:00am 8/11/11 9:00am

Scientists bend time to create invisible light

Within the tight confines of a fiber-optic cable, some researchers at Cornell have managed to create an invisible flash of light. It's invisible not because the flash is manipulated to be hidden, but because the stretch of time during which it happened is erased by the time the flash gets to the other end of the… » 7/15/11 1:00pm 7/15/11 1:00pm

Imagining Life After the Invisibility Cloak

Researchers claim that the creation of an invisibility cloak is feasible with future technology, and that soon humans could have the ability to blend in with their surroundings. Not content to wait for science to catch up with imagination, Dutch artist Desiree Palmen uses paint to camouflage her subjects, giving us a… » 12/05/08 8:30am 12/05/08 8:30am

Invisibility: Just One Facet of the Wide, Wild World of Optical…

Cat's eyes look creepy because, at certain sudden angles, they reflect light directly back at you, the viewer. The ever-popular question of invisibility is wrapped up in that ability to reflect light at certain directions, commonly known as the refractive index. This week, two physicists from the UK and the Czech… » 11/30/08 4:00pm 11/30/08 4:00pm

Secrets of the Metamaterials that Will Make You Invisible

Invisibility used to be the stuff of comic books and Harry Potter novels. But this week, scientists from UC Berkeley have emerged with two new invisibility-producing "metamaterials," engineered substances that bend electromagnetic waves in ways they've never bent before. They call it "negative refraction." But you… » 8/12/08 3:20pm 8/12/08 3:20pm
