The metal-metabolizing Shewanella oneidensis microbe does not just cling to metal in its environment, as previously thought. Instead, it harvests electrochemical energy obtained upon contact with the metal and swims furiously for a few minutes before landing again.
Electrokinesis is more than... Read More
Bacteria dance the electric slide, officially named electrokinesis by the USC geobiologists who discovered the phenomenon.
Their study, published online today in PNAS Early Edition, describes what appears to be an entirely new bacterial behavior.
