SOURCE: http://www.sciencedaily.com/releases/2017/07/170726131758.htm Ribonucleic acid (RNA) is used to create logic circuits capable of performing various computations. In new experiments, Green and his colleagues have incorporated RNA logic gates into living bacterial cells, which act like tiny computers. In new research, Alex Green, a professor at ASU's Biodesign Institute, demonstrates how living cells can be induced to carry out computations in the manner of tiny robots or computers. The approach described uses circuits composed of ribonucleic acid or RNA. These circuit designs, which resemble conventional electronic circuits, self-assemble in bacterial cells, allowing them to sense incoming messages and respond to them by producing a particular computational output, (in this case, a protein). Ultimately, researchers hope to induce cells to communicate with one another via programmable molecular signals, forming a truly interactive, brain-like network. Oh Boy, Is this the beginning of the next phase of human evolution? Will our bodies one day become completely living computers? What's next, infared transmitters so our bodies can control devices? Science Fiction turning into Real Science! |
