Computer-Controlled Bacteria Build a Miniature Pyramid
2010 03 29

By Stuart Fox | PopSci.com

While so many scientists spend their time trying to create nanobots the size of bacteria, researcher at the NanoRobotics Laboratory of the École Polytechnique de Montréal, Canada, decided to simply take direct control of live bacteria. 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. In another, they directed bacteria through the blood stream of a rat, like in Innerspace.


If you’re wondering which ancient pyramid inspired the researchers -- and is shown in the video on the left bottom corner -- it’s the Djoser step pyramid, in Egypt, which the researcher note was "an important, initial milestone in the history of man-made structures."

In the future, the researchers want to use the bacteria as a propulsion system for larger nanorobots that could deliver drugs, repair an organ, or assemble larger and more complex nanostructures.

But, as I mention with every video, don’t take my word for it when you can check it out for yourself! In the video below, you can actually watch the bacterial swarm assemble a tiny pyramid:

Biofuel created from corn waste may not be the clean, eco-friendly oil alternative the United States government is hoping for. A new study has found that fuel generated from harvested corn leftovers creates more greenhouse gases than conventional gasoline — at least in the short term. The fuel under study, called cellulosic ethanol, has been touted in recent years as a ...
