Bacteria Build Micro-Pyramid, Controlled By Computers [Video]

Scientists in Montreal have succeeded in coaxing magnet-sensitive bacteria into building a pyramid, using only carefully manipulated magnetic fields controlled via computer. The hope, ultimately, is that computer-controlled bacteria may someday replace nanorobots or serve as “a propulsion system for larger nanorobots that could deliver drugs, repair an organ, or assemble larger and more complex nanostructures,” giving us yet another thing to fear will turn us all into grey goo.
