While not the first bunch to try and mesh invisibility with military equipment, the British Army is reportedly staying busy by "testing technology it claims makes tanks and troops invisible." Apparently, the (previously) uber-secret trials were conducted by the Royal Engineers and scientists from QinetiQ, and if eyewitness reports are to be believed, they were able to "make a vehicle seem to completely disappear." The illusion (read: we're no closer to actual invisibility cloaks) was reportedly created by utilizing "cameras and projectors to beam images captured from the surrounding landscape onto a specially-adapted tank coated with silicon to maximize their reflective qualities," and if things go as planned, these elusive machines could make their way onto the battlefield "within five years." 'Course, it's not like anyone will have visual proof of that, but we suppose that's just the nature of the beast.

In a move seemingly influenced in equal parts by Halo and David Lynch's film Dune, Darpa has announced that it's ponying up $15 million to develop one-way-invisible, self-healing, shoot-through shields for use in urban combat. While the Pentagon's research division acknowledges that there are "significant technical obstacles" in the process, it's fairly gung-ho about developing a technology combining metamaterials, 'coded' obscurant systems, and a bunch of other stuff no one really understands. Trust us, you'll thank them if the Harkonens try and overthrow your spice-mining operation.

We've got next-to-invisible objects and cameras with ridiculously large sensors, and thanks to a team of brilliant researchers over in Germany, now we've got "an exotic material with a negative refractive index for visible light." Gunnar Dolling and his colleagues at the University of Karlsruhe in Germany have created a metamaterial with layers of silver sandwiching a thin sliver of nonconducting magnesium fluoride on a glass sheet, and once an array of square holes were etched in, his tests showed that the "structure had a negative refractive index of -0.6 for light with a wavelength of 780-nanometers," besting the previous record of 1,400-nanometers. While the scientific babble may not mean much to you, the long and short of it is that this discovery could "lead to further breakthroughs in invisibility cloaks, which could hide objects from the human eye" and make escaping your troubles quite a bit easier. Moreover, the technology could be used in "superlenses" to see details "finer than the wavelength of visible light," but Dolling is reportedly more interested in studying the effects of his discovery than attempting to build any mystical devices, which is probably for the good of mankind, anyway.

Yes, everyone wants an invisibility cloak. Yes, it's been theorized and in development before. But now, what our friends across the pond have only imagined, scientists at an American university have actually built. A group of brainiacs at Duke University have built a device (based on the Imperial College London theory) that can deflect microwave beams so the beams flow around an object almost as if nothing was there, with not too much distortion (but only in two dimensions). In order to do this, the group built a series of concentric circles made up of "metamaterials," or "artificial composites that can be made to interact with electromagnetic waves in ways that natural materials cannot reproduce." Don't get too excited yet, as scientists warn that this is merely a "baby step." The next step is to make the cloak work in three dimensions, and make improve the cloak's effectiveness. And even still, we're a long way off from making something completely disappear from visibility, which "would have to simultaneously interact with all of the wavelengths, or colors, that make up light." said David R. Smith, a member of the research squad. Hey Duke team, if you ever need human test subjects, we'd definitely be willing to volunteer.
