Scientists call their discovery a 'perfect' invisibility cloak

Functional "cloaking" devices have been around since 2006, but they're far from perfect. All attempts so far have failed to avoid at least some partial light and reflectivity — what has resulted in an unconvincing effect. Part of the problem is finding a way to hide objects in wavelengths longer than the human eye can… » 11/12/12 8:00am 11/12/12 8:00am

Two Physics Breakthroughs That Will One Day Lead to Superarmor

The strange field of metamaterials offers some weird optical effects, like cloaking and superlenses. Recently, two breakthroughs in the field, involving programmable materials and gold nano-corkscrews, just made this exotic nano-stuff a little more practical, and maybe even stranger. » 8/20/09 3:30pm 8/20/09 3:30pm

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
