Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these systems ...

A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

A DNA-based computer uses simple base-pairing to create AND and OR logic gates. 130 different double-stranded molecules later, the answer to a square root calculation popped out.
