Researchers at Davidson College have created a living computer. Researchers bred the computer from e-coli rather than using stamped silica and used it to solve a mathematical puzzle known as the Burnt Pancake Problem.
"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."
