Scientists have figured out a way to control nanobots using a molecular device that was inspired by the human brain. Sounds like the makings of a sci-fi thriller.

The control device is only two billionths of a meter across and is made from 17 molecules of the chemical duroquinone. The molecules act as switches, much as how ones and zeros are used in computers.

The idea was inspired by the parallel communication of glial cells in our own brain. Glial cells are known as the glue that keeps our nervous system together.

Scientists were able to control up to eight nano-machines with this device. It may seem paltry right now, but a journey of a thousand nanobots begins with eight, as Lao Tzu said. Well, maybe that's not exactly what he said, but you get the idea.

The potential of such a discovery is exciting to say the least. Aside from the blockbuster movies it would inspire, the technology would be extremely useful in medicine. Imagine nanobots being able to combat tumors and diseases on command (sic 'em, boys!).
