Nano-watch has steady hands
A new nanomechanical hand shows the time of an electronic clock, by spinning a tiny cylinder using light. A silicon nanorod, less than a thousandth of a millimetre long, can be trapped in thin air using focused laser beams, and spun to follow the ticking of a clock, losing only one-millionth of a second over four days.
