A free, open-to-all seminar at Imperial College London on the biophysics of aquatic microbes. Speaker Dr Johannes Keegstra explores how bacteria search for dilute nutrient hotspots, why motility is their most expensive trait, and how sticky polysaccharides from algae guide them. He also shows how bacterial chemosensory arrays use signalling fluctuations to navigate information-poor waters.
