Towards a non-equilibrium statistical mechanics approach of biological systems

Collective phenomena are observed in biological systems at all scales, from bacterial systems to sheep herds. Provided that the biological system consists of independent units without a central control system, we can expect the observed collective behavior to emerge from simple rules among the interacting units. I will show that such a non-equilibrium statistical mechanics approach allows to explain two very different biological systems at two very different scales: the formation of moving clusters in myxobacteria and density waves in sheep herds.
