America's fleet of Predator UAVs could soon become even harder to shoot down (or even detect for that matter) thanks to a new kind of camouflage developed at UC San Diego. UCSD professor Boubacar Kante and his team published their findings last mon...
When you think of Disney, most typically think of animated movies and theme parks, but Disney also has a research arm that looks into all sorts of future technology. Researchers at Disney have created an interesting and very cheap power generator that uses pieces of paper. This won’t create enough power to run your computer, but it does generate enough electricity to make LEDs glow, make sounds, or turn on an e-book display.
The generator uses sheets of conductive Teflon to create an electrical charge as users rub, touch or tap its surfaces together. Circuits are then able to take advantage of that electric charge and harness it to create power for small electronic devices.
The researchers say the generators are extremely cheap and convenient to produce. Such generators could to add interactivity to just about anything you can think of. Disney sees the potential for such generators to be used to power interactivity in books, papers, magazines, posters, and a number of other places.
Researcher Ivan Poupyrev said, “This simplicity leads to countless applications enabling interactivity everywhere and anytime. My overall goal is to make the whole world interactive, and creating ubiquitous power supplies is a key step in that direction.”

Grab your Marauder's Map and get ready to roll. Researchers at Zhejiang University in China have pioneered a new, time-efficient method of producing real world invisibility cloaks made out of Teflon. While it isn't the first time we've come across an invisibility cloak, it is the first to make use of an innovation called topology optimization. Thus far, physicists working on invisibility have largely relied on metamaterials -- synthetic materials that alter the behavior of light as it interacts with objects -- but the cost and difficulty of manufacturing them has made them an impractical option. The Zhejiang team has circumvented those obstacles by creating a so-called "eyelid" out of Teflon, the computer-altered topology of which minimizes the distortion of light as it moves past a cloaked object -- and it only took 15 minutes to produce. Since the Teflon eyelid is only invisible to microwaves, it won't enable you to roam the halls of Hogwarts unseen, but the technology could potentially open up new avenues in exploring invisibility on other wavelengths.

When a team of Harvard researchers wanted to create the ultimate liquid- and solid-repelling surface, they looked toward the Nepenthes pitcher plant, where curious insects check in and never check out, thanks to slippery walls that lead to their tiny, horrific fate. The tropical plant inspired the creation of SLIPS (Self-healing, Slippery Liquid-Infused Porous Surface), a synthetic material that utilizes nano/ microstructured substrates, capable of repelling just about anything you can throw at it. During a visit to the hallowed Crimson halls, the team was kindly enough to show off the material through a series of messy, messy demos, dropping water, motor oil, liquid asphalt and newly-mixed concrete on aluminum and glass. The team even went crazy with a can of black spray paint, comparing the results to a Teflon surface. The outcome was the same in all case -- an amazingly repellent material.
The team has published a number of papers on the stuff, including ones that demonstrate its ice- and bacteria-repelling properties. Oh, and like its natural inspiration, SLIPS does a great jobs keeping bugs off its surface. You can check out our demos and one unhappy ant filmed by the SLIPS team. No insects were harmed in the making of our video, at least -- and the lab assures us that ant had a good life before learning the hard way why it shouldn't mess with Harvard scientists.
