Scientists step closer to creating test tube intelligence


Supercomputers, robots and the human brain represent the artifacts of a long evolutionary chain stretching back to a soupy mass of molecules floating in Earth’s oceans billions of years ago. Now researchers have gone back to the primordial ooze by creating a new type of artificial intelligence based on DNA inside of test tubes.

The resulting artificial neural network is based on an oversimplified model of how brain cells work, but uses DNA instead of the usual silicon chips. It showed that biochemical molecules such as DNA can replicate the pattern-recognition abilities...........
