Sep 15, 2005-- Scientists at Edinburgh University have developed a way of moving an object without touching it, a breakthrough which could be as revolutionary as the discovery of electricity. The researchers have been able to move objects across surfaces with nothing more than a light beam. While the movements of these nanomachines are tiny, their scale is akin to a conventional mechanical machine using a millimeter displacement of pistons to lift an object twice the height of the world's tallest building.
