Flipping flapjacks with E.coli
This is a talk I caught on NPR's Talk of the Nation: Science Friday (5/23) where a Dr. Karmella A. Haynes
used an E.coli culture to solve the burnt pancake
problem. It's interesting and I've hadn't seen E.coli used for as a computing device before.
This was a iGEM project from 2006 and their project page
has a more technical synopsis.
