Physics Colloqium this week

Just in case anyone here was interested, the Physics Colloqium for this week is titled "Nonlinear dynamic phase contrast microscopy for microfluidic and molecular biology applications". The abstract for the talk can be found here. It will be held Friday (11th September), 4pm in 7-222.

    I couldn't make it in the end...How was "[t]he only colloqium ever to mentionthe flagella of E. coli"?

    I've been misquoted Tomas - I did say "quite possibly the only...". I'm not going to go out on a limb and say "only" because I haven't been to enough colloquia to be able to safely say that :P

    It was not bad. There was a significant part which talked about a new phase contrast microscope (well, really a new phase contrast microscope filter) that allowed the study of the dynamics of bacterial flagella possible. So there was a bit about studying bacteria moving in a fluid freely, and then optical tweezers were used to hold the bacteria in place, so just the motion of the flagellum could be studied. There were lots of movies of bacteria!

    I wanted to go to this!! (plant i.d. class prevented me...) Kristen, did she say how long the new approach to filtering phase contrast microscopes has been around for?

    Also, i wonder if that dynamic phase contrast technique could be useful in understanding biofilms. Could we use it to look really closely (and empirically!) at the flow of fluid around different biofilm structures?
