Dynamic patterns of biological systems — •Tobias Reichenbach — Laboratory of Sensory Neuroscience, The Rockefeller University, New York, USA

The formation of complex spatial patterns in biology enables differentiation, for example into separate functional parts, and therefore constitutes a necessity of life. Constantly working against entropy increase by active processes, living organisms operate, from a physical point of view, far from thermal equilibrium. The emerging patterns thereby exhibit a variety of special physical and mathematical characteristics, distinctly different from equilibrium patterns. In this talk, we present two examples of biological structure formation: molecular transport in eukaryotic cells and segregation of bacterial strains, enabling species diversity. We study these by employing generic models that provide insight into the respective mechanism of pattern formation, at the interplay of deterministic dynamics and unavoidable fluctuations.
