### Bacteria-Run Computer Solves Math Puzzle

Eric Bland, Discovery News

May 28, 2008 -- A new living computer, bred from E. coli bacteria instead of stamped from silica, has for the first time successfully solved a classic mathematical puzzle known as the Burnt Pancake Problem.

While this bacteria-based computer is more proof of concept than practical, a living computer might one day solve complex mathematical problems faster than silicon supercomputers.

In a biology-based computer, each bacterium becomes a single computer that runs a different part of the problem simultaneously. Since a million bacteria-based computers can fit into a single drop of water, all of them working together could speed up the calculations dramatically.

"this will open the door to a wide variety of biological computing."
