There are tons of varieties of electric cars, from the DeLorean to the Roberts, but now there is also one that is microscopic. Syuzanna Harutyunyan, of University of Groningen, and her team have been working on the smallest electric car ever and seem to have pulled it off by manipulating a molecule's tendancy to rearrange itself for maximum energy efficiency. Basically, through using this process, Harutyunyan and her team were able to create little electric wheel-like things that will run when powered by electricity.

A few weeks ago, news broke that scientists at the CERN laboratory observed what could be particles traveling faster than the speed of light. With such physics-shaking implications on their hands, the researchers put out a call for independent verification. Though there have been a flurry of responses, one from the University of Groningen's Ronald van Elburg could be the sweeping refutation that puts this issue to rest. Emphasis on "could be." In the original experiment, called OPERA, scientists measured how long it took for particles called neutrinos created at CERN to arrive at the Gran Sasso Laboratory in Italy. The distance between the laboratories (roughly 454 miles), and the fact that Gran Sasso is located underneath quite a bit of mountain, complicated the experiment since synchronizing two clocks in different locations is extremely difficult. In order to account for this, the scientists relied on the time signal from an orbiting GPS satellite. Using this benchmark, the researchers found that the neutrino arrived 60 nanoseconds earlier than light would. However, it's this reliance on an orbital clock that van Elburg says is causing the results observed in the OPERA experiment.
The University of Groningen in the Netherlands made this 32.8 ft. by 9.2 ft. touchscreen interface from six expensive cameras... and some "cheap" infrared emitters, 1000 LEDs, some old computers that were sitting around, and some free software. The result is a positively enormous curved screen with a resolution of 4900 by 1700 that can track 100 different touches at a time... and that's just at optimum speeds. Latency is between 30 and 50 ms. Anyone up for a game of Pong? (Ignore the last minute of video. It's just black. There's no stinger. We were confused, too.) (via Bit Rebels.)
