Israeli scientists have followed Mother Nature’s lead and built a DNA computer so tiny it can perform a billion operations per second.

Some scientists think the miniaturization of computers is reaching its limit. They’re turning to DNA molecules which store and process encoded data in living organisms for faster processing.

The DNA computer is so small that a trillion of them could fit in a test tube. When the computers ran in parallel, they were able to solve a problem.

Biomolecular nanomachines have a long way to go before they become practical, but they may one day find uses in screening libraries of DNA sequences, or even inside cells, where they could monitor conditions and synthesize drugs.

Professor Ehud Shapiro of the Weizmann Institute built the first DNA computer with automated functions.

Until now, DNA computers have needed a series of reactions and human supervision to work. Shapiro’s invention requires only the right molecular mix.
