Calculating Bacteria: Real Computer Bugs?

Computer logic usually consists of electronic switches, but recently scientists have been exploring alternative means for conducting calculations. 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.
