The technique was previously used to build the largest-ever DNA circuit, one that can compute square roots, according to Caltech.

In the latest research, the team trained the neural network to play a memory game in which it would correctly "identify" four scientists based on specific yes or no questions--for instance whether the scientist was British.

Players dropped DNA strands representing an incomplete set of answers into a test tube. The network then provides the answer--the identity of the correct scientist--by fluorescent signals.

When presented with 27 different ways of answering the questions, the DNA "brain" responded correctly each time.
