They manage to create biological computer components by bacteria

28 11 2011

Research staff of the Imperial College London (United Kingdom) He has shown that basic data processing units can be built, commonly used in digital devices such as computers and microprocessors, by intestinal bacteria with the modified DNA. This discovery is an extraordinary improvement in order to develop microscopic biological computers.The research carried out at Imperial College can lead to new instruments that could detect and neutralize toxic outbreaks and disarm fatal cancers in the body.


Currently all computing devices based on Silicon circuits composed of electronic devices capable of processing digital data, what computer language is called logic gates. These devices work off or on depending on the encoding of data into zeros and ones of binary language used by all computer systems.

Now, a study headed by Richard Kitney Imperial College has managed to prove that you can build logic gates using bacteria Escherichia coli (E. coli), which are commonly found in the large intestine. The success of this experiment is in the modification of the DNA of the bacteria so that, by chemical stimulation, is “turn off” o “come on” imitating the operation of conventional electronic logic gates.

Another important feature of these biological logic gates is its modularity, allowing you to join in order to create more complex networks, as electronic chips combine to render a larger amount of data.

Although still a long way to go, the research team suggests that this discovery is a giant step in order to build microscopic biological processors. These small biological computers, that you remain a utopia for the international scientific community, they would be a great revolution in the medical sector, because that could be inserted into the human body through the blood, to combat various diseases in a selective manner, detect and destroy cancerous cells or neutralize harmful toxins, among other possible applications.

Really very interesting as well as quantum computers. I guess that we still wait to see to the successors of the Silicon microprocessor.

A greeting.

My brother recommended I may like this web site.
He was totally right. This publish truly made my day.
You cann’t believe simply how much time I had spent for this information!
Thanks!
