Shigeru Kondo spent some $18,000 to build a desktop Windows computer that, over the course of three months, shattered the world record for calculating pi.

Now a team of scientists at Missouri State Western University and Davidson University has devised a bacterial computer that can solve complex equations, using the bacteria as the brains.
