Invisible

Of all the superpowers in the animal kingdom, the squid’s ability to turn invisible is one of the coolest. And now scientists at UC Irvine have managed to recreate that in human cells for the first time, granting them tuneable transparency.

Researchers at the University of Utah have devised a method to create invisible images embedded within normal-looking images using cheap inkjet printers. The data hidden in these images can then only be revealed using sub-millimeter electromagnetic radiation

iHear, an invisible hearing aid, is designed to significantly lower the cost of personalized hearing devices by enabling the user to test the extent of their condition and calibrate the hearing aid from their own home.

It's often a case of swings and roundabouts. If you save money by buying a house out of town, you spend more time and money commuting. According to a new analysis, the better an object is hidden by an invisibility cloak at one color of light, the easier it is to see at other colors.

Researchers has created a new visualization tool that can render a room containing a partially or completely cloaked object, showing the visual effects of such a cloaking mechanism and its imperfections.

QinetiQ and Vestas have created stealth technology for wind turbines which make them virtually invisible to radar

Chinese researchers may have found a way to an Harry Potter-style invisibility cloak with an invisible gateway potentially able to block out all electromagnetic waves.

Active cloaking, a newly theorized approach to invisibility, brings us one step closer to achieving invisibility in the visible light spectrum.

Scientists are working on a plan to use light bending metamaterials to create the ultimate stealth vessel, which will be invisible to radar, missiles, and even the human eye according to a report in Physics World.
