Disney has developed a new technology that allows you to generate energy by simply rubbing or touching a piece of paper. This is something the world needs because, you know, everything will require a level of interactivity in the future—even old-fashioned paper books.

CT, or computed tomography, scans are to x-rays what 3D movies are to classic 2D flicks. But instead of being just some gimmick to lure patrons into a theater, CT scans result in 3D models that let doctors study internal medical conditions in amazing detail. But why stop there? Researchers at the Fraunhofer Institute have now built a monstrous CT scanner that can scan entire cars and even shipping containers.

There are huge number of headphones available on the market today running the gamut from dirt cheap to incredibly expensive. There are headphones aimed at everyone from users who don’t really care what the music sounds like all the way up to audiophiles who will pay huge money to hear every little nuance in their favorite tracks. One thing all of those headphones have in common is that the speaker drivers use moving parts.
A group of researchers have created a new type of headphone that uses a driver with no moving parts, based on carbon nanotubes. The headphones are able to create sound using thermoacoustic effect. That means that sound is created relying on the expansion and contraction of air.
It’s unclear at this point how high the quality of music these carbon nanotube speakers will be able to create. We don’t know if it will be an everyman headset or capable of creating audiophile grade sound.
We also don’t know how much headphones using carbon nanotubes will cost or when they might be available. However, early indications are that headphones using this technology could be reasonably priced, since they could be produced using techniques similar to those used to create computer chips.

Kids these days don’t want to play with wooden blocks—they want to play wooden block games on a tablet. But Felix Heibeck has come up with a wonderful way to lure kids away from their touchscreens by adding electronic and interactive blocks to those wooden marble mazes, cleverly bridging both worlds.

Over the years, headphones have become very ubiquitous. You can buy them for a few dollars in the checkout lane at your local Walmart and many smartphones ship with a cheap generic pair of headphones right and the box. It also spend hundreds of dollars on audiophile grade headphones. One thing that all these headphones […]
Scientists and archaeologists have discovered ancient tales of a particularly cold summer from the year of 1258. It has been called the “year without a summer” and was describing these ancient texts as being unseasonably cold resulting in poor harvests that were also devastated by heavy flooding. Those ancient reports indicate that thousands of people […]
Nothing about how a bunch of Oxford researchers recently pulled neural stem cells out of the brains of living rats seems feasible. The cells are hard to isolate. Brains are fragile. Okay, brains are very fragile. But they’ve done it, and the procedure could shed fresh light on diseases like Parkinson’s and multiple sclerosis.
