Why Living Cells Are The Future Of Data Processing

•, By Adam Baer
 Not all computers are made of silicon. By definition, a computer is anything that processes data, performs calculations, or uses so-called logic gates to turn inputs (for example, 1s and 0s in binary code) into outputs. And now, a small international community of scientists is working to expand the realm of computers to include cells, animals, and other living organisms. Some of their experiments are highly theoretical; others represent the first steps toward usable biological computers. All are attempts to make life perform work now done by chips and circuit boards.

Last year, for example, a computer scientist at the University of the West of England named Andy Adam­atzky and a team of Japanese researchers built logic gates that ran on soldier crabs. First they constructed mazes that replicated the shape of the wires in a computer’s logic gates.
