Tiny bacteria may seem rather unintelligent, but a bacterial crowd can accomplish the Sisyphean task of turning microgears millions of times bigger than themselves. The microbes start out by swimming randomly, but occasionally collide with the spokes of a gear and begin pushing. Scientists from the U.S. Department of Energy's (DOE) Argonne National Laboratory and Northwestern University observed a crowd gather and push against the spokes.
Several hundred bacteria teamed up in order to turn one gear. When multiple gears sat next to one another with spokes connected, like in a clock, the bacteria began turning both gears in opposite directions, and created a synchronous movement.
This could lead to more sophisticated biomechanical systems, which combine the powers of tiny bacteria or nanobots with hard materials to form a "smart material." Surely crowds of tiny slaves creating nanogears can't be far behind, if they don't just assemble themselves.
On the downside, this could mark the beginning of a Microgears of War-style conflict. Just don't drop the antibiotic bomb.
So if you were to accidentally break a watch with these little buggers powering it, you could potentially release an army of smart bacteria into the world looking to take vengeance against their former masters. That's just a great idea.
Armed with nano-sized flame throwers and machine guns, how could you defeat such a threat?
Nano sized molded oranges.
Bloody hell what am I going to do now with 500 000 hamsters and their wheels? Blasted bacteria. My entire fortune wasted, WASTED I say. I never saw this coming. Who would have thought my hamster on a wheel scheme would be bested by a bunch of microscopic pests. Make with the antibiotics post haste!
