Big waves can be bad news for coastal areas, and over time, even moderate wave action can erode beaches down to nothing. In one of those schemes that sounds crazy but isn't, Chinese researchers have developed a system that uses concrete cylinders to render coastlines effectively invisible to incoming waves.
The last few invisibility cloaks we've seen have relied on metamaterials to make tiny objects invisible to a specific wavelength of light. This "carpet cloak," from MIT, uses some calcite crystals to make much larger objects disappear in the visible spectrum.
Who would have thunk that the secret to invisibility might be within that of the multi-armed squid? The U.S. Navy is pumping $5 million into a team of scientists at Duke University over the next five years to see if they can tap into the squid's special "light sensitive organs" for use on the battlefield.
Scientists have proven in a very small experiment that it's possible to create a "temporal cloak" that can make you invisible by opening a gap between light waves. The science is pretty wild, but it actually works.
It's the ultimate dream item for perverts everywhere: the invisibility cloak. Long the realm of sci-fi, it's been something thats understandably not yet around. But it may actually become a reality in the future thanks to a new "metamaterial."
Making things invisible is a pretty neat trick. In 2006, a team of Duke University scientists bent rays of light around a copper ring (which was still visible, thanks to pesky visible light). Now researchers say they are getting...
Cloaking technology doesn't only exist in the realm of science fiction: researchers at Imperial College London are trying to create a cloaking blanket to hide objects in visible light — something that has never been done. Visible light's small...
