Computing Comes to Life
15 March 2002: Research funded by NASA has led to a crude DNA-based computer able to solve a logic problem, as reported in the journal Science this week. USC computer science professor Leonard Adleman showed in 1994 that DNA, the molecule that holds life's genetic code, could be used to find the shortest route among seven cities, a relatively simple problem. His new experiment solved a problem requiring the evaluation of more than one million possible solutions. In computer parlance, a DNA computer operates in parallel, with countless molecules shimmying around together at once. Commercial DNA computers are a long ways off, but Adleman says they "compute with extremely high energy-efficiency and store enormous quantities of information."
