  • The mechanism allowing sperm to steer is not fully understood. The authors find that superposition of two harmonic waves breaks the flagellar beat symmetry temporally rather than spatially, and that this mechanism is enhanced by the sexual hormone progesterone, which changes the motility pattern.

  • Filaments of the FtsZ protein can form chiral assemblies. Now, active matter tools link the microscopic structure of active filaments to the large-scale collective phase of these assemblies.

  • Cells are in constant movement inside tissues, but often remain cohesive nevertheless, i.e., single cells do not escape from the colony edges. Using an active Brownian-particle model with attraction, in this paper the authors develop an interaction potential that reproduces experimental observations describing the motion of epithelial sheets under different conditions.

  • Active matter locally dissipates energy to produce systematic motion. This Perspective highlights proliferation as a special type of activity that breaks particle number conservation and thereby gives rise to a unique set of collective phenomena characteristic of life.
