Aurispector writes: An article on LiveScience says a newly discovered repulsive aspect to light could one day control telecommunications devices with greater speed and less power. The discovery could lead to nanodevices controlled by light rather than electricity. "The discovery was made by splitting infrared light into two beams that each travel on a different length of silicon nanowire, called a waveguide. The two light beams became out of phase with one another, creating a push, or repulsive force, with an intensity that can be controlled; the more out of phase the two light beams, the stronger the force." As an added bonus, nerds may no longer need LED's to trick out their custom gaming rigs!
