Navy Battleship with a Cloaking Device

Meet the first (semi) invisible warship: it's painted in "low reflectivity" materials that make it hard to see on radar. While not invisible to the naked eye, this Swedish ship, called the Visby Corvette, is for all intents and purposes invisible to many of the instruments Navies would use to pick it up. Researchers say the next generation of high-stealth ships like this might be invisible to the naked eye, too. Want to see more of this invisible ship? More »

One Step Closer to a True Cloaking Device

Last year, a team at Duke announced a beta cloaking material whose special nano-properties make it "invisible" to microwaves. Today, however, researchers in Stuttgart have got something even better — a "metamaterial" that can cloak objects in the visible light spectrum. Made of gold nano-mesh, the material has a negative refraction index for visible light — that means it doesn't reflect light, and could give the illusion of blending into the background. I can't wait for my metamaterial full body suit for doing futuristic spy shit. Towards Cloaking Visible Light [Science Daily]

Step into My Wormhole and Become Invisible

Math geeks at University of Rochester say it's theoretically possible to create a wormhole between two locations. The beauty part is that you'd be invisible while you travel between them. The tech you'd use to do this sounds a little like Philip K. Dick's "scramble suit" from A Scanner Darkly. "Metamaterials" that bend electromagnetic fields would create a space from which light couldn't escape, thus making you effectively invisible as you "tunneled" to another spot. When are they going to start selling this at Radio Shack?Electomagnetic wormholes possible with invisibility technology [via University of Rochester]
