Recent work in DNA biocomputing

According to a press release, a team of scientists at the Weizmann Institute of Science in Israel a simple biocomputer (a programmable two-state, two-symbol finite automaton) using DNA molecules and enzymes. The work was reported in the 22 November 2001 issue of Nature. According to the press release, ìCollectively, the computers perform a billion operations per second with greater than 99.8% accuracy per operation while requiring less than a billionth of a Watt of power. This study may lead to future computers that can operate within the human body, interacting with its biochemical environment to yield far-reaching biological and pharmaceutical applications.î
