New DNA Computer Functions sans Fuel - Sarah Graham, Scientific American
In 2001, scientists at the Weizmann Institute of Science in Israel announced that they had manufactured a computer so small that a single drop of water would hold a trillion of the machines. The devices used DNA and enzymes as their software and hardware and could collectively perform a billion transitions each second. Now the same team, led by Ehud Shapiro, has announced a novel model of its biomolecular machine that no longer requires an external energy source and performs 50 times faster than its predecessor did. The Guinness Book of World Records has crowned it the world's smallest biological computing device.
