We would all love to own an invisibility cloak. But new research suggests that if they do ever exist they won't be perfect: They will be more like Predator, less like Harry Potter.

Scientists now have a way to method of cloaking something very small, making it effectively invisible. But what if scientists and engineers created a much larger version? What if we all had access to invisibility cloaks?
AVG is a name well-known in the Windows world for its decent and free anti-virus software, but the company is apparently looking to expand outside of just software and protect people's privacy in the real world now. At Mobile World Congress, AVG is demoing a concept pair of glasses that both foil facial recognition software, and make it difficult for someone to snap a photo of your face.
Invisibility is perhaps the most ubiquitous of sci-fi dreams: Spy movies, video games, and classic cartoons all tantalise us with this trick. Researchers at the University of Rochester still haven't unlocked the secret to that elusive invisibility cloak either, I'm afraid. But they made a very cool optical illusion that looks the part.
The last time Keio University was in the news it was for a prototype wearable cloaking device developed by a team of researchers at the school. A decade later you still can't go out and buy one, but the research has inspired another brilliant use for the technology — invisible car interiors that let you see everything outside when backing up.
Mercedes claims that its new fuel cell technology results in vehicles with no omissions, so it's as if they're invisible to the environment. And to drive this fact home, literally, they created a vehicle that was invisible to everything else.
Hiding behind a life-sized negative of yourself won't actually turn you invisible. But researchers at the University of Texas at Austin have figured out how to use that same idea to make real-world objects vanish when shot with microwave energy.
The Invisibility app is indeed magical. It takes a mediocre camera on your iPad 2 and turns it into something incredible.
Watch very closely as the camera pans around this landscape and try to locate the horde of soldiers - 20? 30? - hiding in plain sight. Apparently, some people in the military need no stinking magic cloaking technology to become invisible.
Invisibility cloak project is back on! It's from a different team of scientists that were using silver-plated nanoparticles in water though, with these latest Harry Potter enthusiasts using photonic metamaterials to change light rays.
