E. coli's Kayak Paddle-Lke Motion Tracked For First Time

E. coli's Kayak Paddle-Lke Motion Tracked For First Time
Yale engineers have for the first time observed and tracked E. coli bacteria moving in a liquid medium with a motion similar to that of a kayak paddle. Their findings, which appear online September 29 in the journal Physical Review Letters, will help lead to a better understanding of how bacteria move from place to place and, potentially, how to keep them from spreading. Scientists have long theorized that the cigar-shaped cell bodies of E.
