Influence of physical interactions on spatiotemporal patterns
Chengjie Luo, David Zwicker
Spatiotemporal patterns are often modeled using reaction-diffusion equations, which combine complex reactions between constituents with ideal diffusive motion. Such descriptions ne…
Physical interactions promote Turing patterns
Lucas Menou, Chengjie Luo, David Zwicker
Turing's mechanism is often invoked to explain periodic patterns in nature, although direct experimental support is scarce. Turing patterns form in reaction-diffusion systems when…
Zonal receptor distributions maximize olfactory information
Swati Sen, David Zwicker
The olfactory sense measures the chemical composition of the environment using a diverse array of olfactory receptors. In vertebrates, the olfactory receptors reside in a mucus lay…
Evolved interactions stabilize many coexisting phases in multicomponent liquids
David Zwicker, Liedewij Laan
Phase separation has emerged as an essential concept for the spatial organization inside biological cells. However, despite the clear relevance to virtually all physiological funct…
Light controls motility and phase separation of photosynthetic microbes
Alexandros A. Fragkopoulos, Jérémy Vachier, Johannes Frey +4
Large ensembles of interacting, out-of-equilibrium agents are a paradigm of active matter. Their constituents' intrinsic activity may entail the spontaneous separation into localiz…
Physical and geometric constraints explain the labyrinth-like shape of the nasal cavity
David Zwicker, Rodolfo Ostilla-Mónico, Daniel E. Lieberman +1
The nasal cavity is a vital component of the respiratory system that heats and humidifies inhaled air in all vertebrates. Despite this common function, the shapes of nasal cavities…
Growth and Division of Active Droplets: A Model for Protocells
David Zwicker, Rabea Seyboldt, Christoph A. Weber +2
It has been proposed that during the early steps in the origin of life, small droplets could have formed via the segregation of molecules from complex mixtures by phase separation.…
Receptor arrays optimized for natural odor statistics
David Zwicker, Arvind Murugan, Michael P. Brenner
Natural odors typically consist of many molecules at different concentrations. It is unclear how the numerous odorant molecules and their possible mixtures are discriminated by rel…
