Nano-bacterial pyramid

I don’t know if this is amazing, but it’s kind of neat.  Gizmodo sez: “The feat was accomplished—and extensively documented in the video above—by researchers at the NanoRobotics Laboratory of the École Polytechnique de Montréal. The bacteria in question are known as magnetotactic bacteria, which have internal compasses that respond to the pull of a magnetic field. The research team used just such a magnetic field to bunch the bacteria together en masse and manipulate their movements to accomplish simple tasks.”
