  • The chemosensing accuracy of E. coli cells is shown to be limited by internal noise in signal processing, rather than the stochasticity of molecule arrivals at their receptors, contrary to long-held understanding in the field.

  • Action potentials in neurons are accompanied by a mechanical displacement of the axonal membrane. Here, the authors present a model to describe these as surface waves which are driven by changes in charge separation, and compare their model to published experimental results from squid giant axons and garfish olfactory nerve bundles.

  • Biopolymers can couple to membrane lipids and condense to prewet membranes. Here a range of membrane perturbations in reconstituted systems and cells show that the prewetting is sensitive to membrane composition and phase transitions and can drive interorganelle contact.

  • The degree of irreversibility of a dynamical system is commonly characterized by the total rate of entropy production. Seara et al. introduce a measure that quantifies irreversibility from data in broad classes of spatiotemporal non-equilibrium systems.

  • Information theory sets an upper limit on the ability of bacteria to navigate up chemical gradients. Experiments reveal that cells do so at speeds within a factor of two of the limit, suggesting they are selected to efficiently use information.
