MITs Kinect of the future can track you through walls
2013-10-18 15:33:56| Extremetech
Researchers from MIT have unveiled a new form of motion tracking that uses a three-point system to follow a person's position, even through a totally opaque wall. Though the word "Kinect" has been thrown around quite liberally for the sake of accessibility, this is strictly a positional tracker -- that means that it won't be interpreting sign language or reading lips any time soon.

MITs self-healing metal fixes tiny flaws before they can create massive problems
2013-10-10 14:00:46| Extremetech
Researchers led by graduate student Guoqiang Xu and professor Michael Demkowicz modeled microscopic cracks in a sheet of nickel with tension applied. Instead of worsening, the cracks became smaller, then closed on their own as the edges fused together. After assuring themselves the effect was real, the next step was figuring out how it happens.

MITs carbon fiber Lego bricks can be fashioned into airplanes, rockets, bridges
2013-08-19 17:37:09| Extremetech
Materials engineers at MIT have created the carbon fiber equivalent of Lego bricks or K'Nex -- interlocking carbon fiber blocks that can be formed into large structures that are 10 times stiffer than comparable ultralight materials. These structures could be mass-produced by automated robots, and fashioned into airplane and rocket fuselages, wings, and bridges, among other things. Interestingly, unlike almost every other object made from composite materials, objects made from MIT's new structure can be easily disassembled or have individual "bricks" replaced when they break.

MITs mobile hotspot sharing app aims for free P2P data coverage
2013-01-28 19:44:30| Extremetech
Mobile hotspots are already useful, but what if you got rewarded for being a good samaritan? That's the idea driving the research project called Air Mobs. If you share data, you'll get credit for usage down the road. MIT's Viral Spaces research group has developed a peer-to-peer wireless tethering system that encourages users to share as much as they use. The Air Mobs app runs in the background, and decides the appropriate time to turn on and off WiFi sharing to the world.
