Save the clunky tricorders for Star Trek. One day, tiny biological computers with DNA-based circuitry could diagnose diseases.

Using snippets of DNA and DNA-clipping chemicals, researchers have created one key component of a computer’s brain: the transistor, a switch that helps electronics perform logic. The biological switch, dubbed a transcriptor, could be plugged together with other biological devices to boost the power of DNA-based computers, researchers report March 28 in Science.
