Fire Alarm Companies

Many simple forms of life on this planet, including some of our earliest ancestors don 't right minds. Instead, they have networks of neurons that fire in response to stimuli that trigger reactions. Scientists at Caltech have indeed how such a primitive pre-brain thought to create DNA strands. Researchers, led by Lulu Qian DNA molecules strung together to create bio-mechanical circuits. By sequencing of the four bases of our genetic code in a special way they could program it to react differently to different inputs. In order to prove their success, the team interviewed the organic circuit basically play 20 questions, feeding it information on the identity of a particular scientist with more DNA strands. The artificial neural network nailed answer every time. Check out the PR and the couple of videos that dig a little deeper into the experiment after the break.
