Nanobrains for nanobots
Researchers, including Dr Anirban Bandyopadhyay of the International Center for Young Scientists, Tsukuba, Japan, have created a chemical ‘brain’ capable of remotely controlling multiple nano-machines. The ‘logic device’ composed of 17 molecules of the chemical duroquinone, is only two and a half nanometers in size. It looks like a ring with four spokes, which can be rotated to four different states. One duroquinone molecule sits in the middle, surrounded by the other 16, connected by hydrogen bonds. The state of the molecule in the middle can be switched using a scanning tunneling microscope (STM), a standard issue nanotech tool. Since instructing one molecule simultaneously activates 16 others, there are four billion different possible combinations of outcome. Researchers say the idea was inspired by the communication of glial cells in the human brain. They tested the logic device by hooking it up to eight nano-elevators, which can be commanded to move up and down about one nanometer, and were able to make all eight function successfully. This development could have big implications for computer technology. Whereas a typical CPU only carries one instruction at a time, one modeled on the logic device could carry 16 simultaneously. The researchers they have already completed faster machines that are capable of 256 and even 1024 concurrent operations. Of course, such a computer’s application is limited, because it relies on STM to work, still, soon these molecular brains may be integrated in other nanobots to bring significant advances in nano-assembly and targeted drug delivery.

Does the fact that underage kids were videotaped drinking alcohol, smoking pot and yes they are sucking lollipops which has everything to do with Ecstacy, mean ANYTHING to you??? If you think they are just kids have lollipops than you need your head examined. Hitler gave to charities too.
