They're Walking, Yes Indeed, They're Talking, 'Bout You and Me
Bacteria are amazing. Each new discovery only adds to our awe. We know that bacteria talk to each other about us and now we learn that they can get up on their feet, special pili, and walk right on up catheters and other surfaces to us. There's a video of one going vertical and running off and the paper that discusses the phenomenon, "Bacteria Use Type IV Pili to Walk Upright and Detach from Surfaces" and its importance in the effort to understand biofilm formation in today's Science Magazine. Hat tip: Houston Chronicle which has a great writeup.
