DNA is like software, telling our cellular and molecular hardware what to do – except it uses biochemical reactions rather than the electronic circuitry of computers we’re used to. Now, researchers ...

After seeing an exhibit of an old relay-based computer as a kid, [Simon] was inspired to build a simple two-relay latching circuit. Since then, he’s been fascinated by how relays can function to do ...

Margaret Dutch’s daughter ran into an unusual math problem while taking the Washington Assessment of Student Learning at Capital High School last week. Her daughter, a sophomore, was given a ...

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 computer made from strands of DNA in a test tube can calculate the square root of numbers up to 900. Chunlei Guo at the University of Rochester in New York state and colleagues developed a computer ...

While DNA-based computing may not be taking over silicon quite so soon, there is progress in the works. In a paper published by Small, researchers from the University of Rochester demonstrate a ...

A biocomputer has demonstrated the advanced computational capabilities DNA-based architecture could bring to future PCs by calculating the square root of 900. As reported by New Scientist, academic ...

A new DNA computer calculates square roots of perfect squares up to 900. Like quantum computers, DNA computers are an exciting frontier of post-silicon computing. Where previous examples were up to 4 ...
