I remember seeing the apparatus in the Woese lab. I was in biochemistry at UIUC, but took
Most of my coursework in microbiology. We hung out with grad students in micro, including John Leigh and others in Woese’s lab.

Good luck with your races! I do believe your microbes are producing molecules that motivate you!!!!!! (From Amy)

Roberto, I love this post. My father’s doctoral advisor (organic chemistry at UTAustin) wrote a book entitled Serendipity and its influence on science. My dad’s favorite quote is the one from Pasteur! Thanks for giving me a lesson in microbiology (about E. coli) and for nice memories about my dad!!

The propagation of waves certainly happens in the myxobacteria in the ripples that they make when aggregating.
