Raphael goes to Aberdeen

Raphael is leaving this evening for Aberdeen! He is going for a conference on Physics and Biology of Active Systems, where he will present his (almost completed) work on bioactive dispersal of tracers. He found a cool effect that was not noticed before but ends up dominating the statistical properties of the tracers, which disperse with an effective diffusivity more than one order of magnitude larger than previously estimated. We’ll write-up soon(ish) so watch this space!

Metachronal Wave Defects on Interface!

The Journal of the Royal Society: Interface just accepted our latest paper, which includes the first report of recurring defects in metachronal coordination of eukaryotic flagella (see also Arxiv version). These defects, which we observe in Volvox carteri, are a type of incomplete coordination which we think might originate from a variation, along the surface of Volvox, in the frequency at which cells beat their flagella. They might be related to so-called chimera states of groups of interacting oscillators…. More to come on this: we’re still working on it!

Ph.D. Student Opening

There is a new opening for a Ph.D. student in the group, to work on movement of microorganisms in response to light. The plan is for this project to kickstart a collaboration with the group of Giovanni Finazzi, at CEA Grenoble (Fr.). More informations can be found here. If you’re interested or know outstanding students that might be interested, do not hesitate to contact Marco! Funding is for UK students or outstanding EU (continental) students only.

New Office!

imageOn a light note, today Raphael and Matteo took possession of their new office, which is now groundfloor in the Physics main building. As you can see, the whiteboard in the office was the vehicle of choice to express the excitement of finally running their own kingdom! 😉
