Computer control device mimics human brain

A MOLECULAR device that mimics the brain and which could one day act as the controlling element for swarms of nano-machines has been invented.

In a report published in Proceedings of the National Academy of Sciences, scientists say the tiny device — just two billionths of a metre across — could be used to boost the processing power of future computers.

It is also hoped the device, which was able to control as many as eight microscopic machines in tests, will pave the way for the use of nano-machines in treating disease.
