  • Myosin motors drive the actin cytoskeleton out-of-equilibrium, but the role of myosin-driven active stresses in the accumulation and dissipation of mechanical work is unclear. Here, the authors synthesize an actomyosin material and find that the rate of entropy production increases non-monotonically with increasing accumulation of active stresses.

  • Certain bacteria cells respond to the stress of long-term exposure to antibiotics by changing their shape. Single-cell experiments and modelling cast this as a mechanical feedback strategy that makes bacteria more adaptive to surviving antibiotics.

  • An observation that cells at the edge of a healing wound readily undergo intercalation leads to the finding that tissue fluidity is crucial for effective wound closure.

  • When a wound heals, different types of branched and bundled actin structure form, each designed to perform a specific function. Experiments and theory now suggest that the actin architecture depends on the stiffness of the cell’s surroundings.

  • The interaction between myosin motors and F-actin is well described, but the impact of actin organization on contractility is not well described. Here the authors use a 2D biomimetic system and computational modelling to show that contractility of isotropic actomyosin is cooperative, and contraction velocity scales with myosin activation area.

  • Many excitable systems share a common feedback motif, but how such feedback acts on biomechanical systems remains largely unexplored. By extending the cellular vertex models to incorporate mechanochemical feedback and excitability, the authors explore how cellular mechanics and geometry regulate the propagation of active stresses in excitable media.
