  • Non-equilibrium mechanical activity in active matter is quantified across spatiotemporal scales through time-reversal-asymmetry measurements of conformational fluctuations of carbon nanotube probes.

  • Experiments show that swimming starfish embryos spontaneously assemble into large chiral crystals that exhibit self-sustained chiral oscillations and unconventional deformation responses characteristic of odd elastic materials.

  • The determination of entropy production from experimental data is a challenge but a recently introduced theoretical tool, the thermodynamic uncertainty relation, allows one to infer a lower bound on entropy production. Here the authors provide a critical assessment of the practical implementation of this tool.

  • Muscle function depends on a highly organized array of actin and myosin filaments. Butkevichet al. identify the C. elegansdrebrin-like protein DBN-1 as an important regulator of actin filament stability in muscle cells, which relocalises from M-lines to I-bands on contraction.

  • Cells exploit protein pattern formation to perform key processes, and do so while undergoing major shape changes. Experiments and theory together reveal a shape-adaptation mechanism capable of controlling protein dynamics even as the cell deforms.

  • Activity in certain living systems can lead to swirling flows akin to turbulence. Here, the authors connect the dynamics of topological defects in starfish oocyte membranes to vortex dynamics in 2D Bose–Einstein condensates.
