SPL - New statistical physics in living matter: non equilibrium states under adaptive control

The marine seagrass Zostera marina plays an important role in coastal ecology. It is occasionally devasted by a unicellular organism, Labyrinthula zosterae, which lives harmlessly on the plant most of the time. As it name suggests, this organism colonises surfaces by building a labyrinthine network of ‘tracks’ along which the cells then move. I will survey what is known about the ‘active matter physics’ of the track building and motility, and then present some results on the ‘logic’ of the network to seek to understand why the organism may have evolved this mode of colonisation and locomotion.
