Music from blocks
Researchers at Southampton University have created a new way to generate computer music. This software, audio d-touch, works with a computer and a webcam. By using simple techniques of computer vision, physical blocks are drawn on a printed circuit. The position of the block then determines how the computer samples and reproduced the sound.

Everything you need is a computer with a webcam and a printer. Each user creates physical objects interactive and combines visual markers recognized by Audio d-touch. The software platform is open and can be extended to applications beyond the synthesis of music.
Batteries more efficient
Improved lithium-ion batteries is the promise we've made in years! But apparently this time it's true because they should be sold within two years. By replacing the graphite electrodes with silicon, researchers at two different universities have created lithium-ion batteries capable of storing two times more energy than today.
Thus, our cell phones will discharge half as fast. During a test, a battery was able to make 250 cycles charge / discharge before recharging capacity falls below 80%. The company is close to a performance of 500 cycles required for a battery of electronic equipment. As for electric vehicles, the battery would require at least 3000 cycles.
