A small team of researchers at the University of Manchester has developed a technique for creating a molecular-based, finite-state machine. Their research was published in the journal Nature. In ...

When British mathematician Alan Turing conceived the notion of a universal programmable computing machine, the word computer typically referred not to an object but to a human being. It was 1936, and ...

A theoretical computer built in a mixed-up mathematical universe might not sound like the most practical invention. But the discovery shows that computation can turn up in the most unlikely places, ...

Vice reports that scientists have created the first known “chemical Turing machine,” meaning a liquid that can do the calculations that define a classic computer science standard. Juan Pérez-Mercader ...
