100 (micro)meter dash

A fun read in the current issue of Nature Reviews Microbiology is an essay entitled "The Microbial Olympics, " just in time for the Summer Olympics.  You will find stories about microbes competing in boxing, javelin, pathogen relay, diving, and other Olympic events.  Flagellated bacteria compete in the 100 micrometer dash, which you can watch below.  (Note that some of the contestants were genetically modified.)

  2. E. coli (proton-driven flagellar motors)
