For the first time humans have played tic tac toe with bacteria. These were no ordinary bacteria, but E. coli extensively genetically modified and set up to act as a simple neural network, a form of artificial intelligence.

This approach could have all kinds of applications, from creating living materials capable of learning to making “smart” microbiomes, says Alfonso Jaramillo at the Spanish National Research Council.

He started his team with an E.coli strain genetically altered …
