  Cellular diversity heals

  Cells in embryonic tissues generate coordinated forces to close small wounds rapidly without scarring. New research shows that large cell-to-cell variations in these forces are a key system feature that surprisingly speeds up wound healing.

  Dynamic force patterns promote collective cell movements during embryonic wound repair

  The motor proteins and contractile forces involved in wound closure are both shown to be heterogeneously distributed around a wound. Theory suggests that this heterogeneity speeds up wound closure, as long as the proteins are mechanically regulated.

  Driven to peak

  A curious peak in the distribution describing stochastic switching in bacterial motility had researchers confounded. But a careful study performed under varying mechanical conditions has now revealed that the breaking of detailed balance is to blame.

  Non-equilibrium effect in the allosteric regulation of the bacterial flagellar switch

  Flagellated bacteria move by alternately rotating their flagella clockwise and counterclockwise with dynamics that are shown here to be torque dependent. This non-equilibrium effect increases motor sensitivity as the torque increases.
