Scientists can now make little-tiny metal gears one-seventh the diameter of a human hair. The uses for such small mechanisms could be incredible. Using a little gear as a saw in extreme one-cell-at-a-time microsurgery might be useful at first, then whole fleets of automatic saw-gear machines could be injected into a person to cut out a brain tumor in medicine of the future
