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!
