With a swipe of a magnet, microscopic 'magno-bots' perform complex maneuvers

Under a microscope, a bouquet of lollipop-like structures, each smaller than a grain of sand, waves gently in a Petri dish of liquid. Suddenly, they snap together, like the jaws of a Venus flytrap, as a scientist waves a small magnet over the dish.
