Science Bag: Microbes in Motion

January 15, 2017 @ 2:00 pm - 3:00 pm

Bacteria have evolved elaborate machines to swim through liquids and to crawl over surfaces. Some construct tiny rotary motors that turn flagella. These function as propellers to allow them to swim. Others extend and retract adhesive filaments called pili to pull themselves over surfaces. Still others propel themselves with miniature tank treads. This show will explore their ingenious strategies, how they control their movements, and the experimental approaches used to study this miniature “traffic.”

Join Mark McBride, professor of biological sciences at UWM, to learn all about these mobile microbes.

The show, which is free and open to the public, runs from 8 to 9 p.m. on Fridays through Jan. 27. There is an additional matinee show at 2 p.m. on Sunday, Jan. 15.
