From ScienceDaily: Only 15 years after University of California, Berkeley, engineers built the first micro-scale motor, a UC Berkeley physicist has created the first nano-scale motor - a gold rotor on a nanotube shaft that could ride on the back of a virus.

The electrostatic motors represent a milestone in nanotechnology, and prove that nanotubes and other nanostructures several hundred times smaller than the diameter of a human hair can be manipulated and assembled into true devices.

Amazing: Light travels at a speed of 300 million metres per second in a vacuum, but in recent years physicists have managed to slow laser pulses down to speeds of metres per second - or to bring them to a complete halt - in ultracold gases. In similar experiments physicists have observed superluminal or faster-than-light pulse propagation. These effects have also been observed in crystals at cryogenic temperatures and in "hot" gases. Now Matthew Bigelow, Nick Lepeshkin and Robert Boyd have observed the same effects in a much simpler system - a crystal at room temperature.

According to New Scientist researchers from Massachusetts Institute of Technology and Harvard Medical School are using nanotechnology to create a functioning vascular system, and expect that in 10 to 15 years, they'll be able to use this procedure in human patients to replace livers or kidneys.
