Computer-Controlled Bacteria Build Microscopic Pyramid


(YouTube Link)


Researchers at the École Polytechnique de Montréal used bacteria that follow magnetic pull to build a tiny pyramid:

By using a computer-controlled magnetic field, the researchers turned the bacteria into fully-compliant biological nanorobots.

The trick was using a type of microbe known as magnetotactic bacteria. These critters have little internal compasses, and will follow the pull of a magnetic field. By manipulating a magnetic field, the researchers tricked the bacteria into forming a giant, computer-controlled swarm. In one experiment, the researchers had the bacterial swarm assemble a small pyramid.


The researchers hope to use this development to perform microscopic tasks normally thought to be the future of nanotechnology, such as organ repair.

Somewhere, I'm hearing millions of tiny voices squeaking "Why is this night different from all other nights..."

And the final fast-forward replay really needs a Yackity-Sax soundtrack.

But how would they trick the bacteria into repairing an organ? It sounds like all the magnetic fields do is tell the bacteria where to go, not what to do once they get there. Its the old "you can lead a horse to water, but you can't make it drink" problem.
