Calculating Bacteria: Real Computer bugs?

Posted on Updated on

I. Flatow, 05.23.2008, Science Friday: A group of scientists reports in the Journal of Biological Engineering that they have created specially modified E. coli bacteria capable of performing one specific type of calculation, a puzzle known as the “pancake flipping problem.” Karmella Haynes, one of the researchers, discusses the prospects for biologically based computing, and ways in which calculating bacteria might be useful.
