"If you wear the right glasses, a lot of what you see inside the cell is computation," says Ehud Shapiro of the Weizmann Institute in Rehovot, Israel. Now Shapiro and his colleagues have turned the computational power of biological molecules to their own ends. The researchers have built a machine that solves mathematical problems using DNA as software and enzymes as hardware. A trillion such biomolecular machines - working at more than 99.8% accuracy - can fit into a drop of water....
