  • Active fluids, such as bacterial suspensions, exhibit chaotic flows at low Reynolds number - a phenomenon known as active turbulence. Here, the authors show a discontinuous transition from laminar to chaotic flows in unconfined active nematics.

  • The flow features of cell monolayers depend on cellular interactions. Now four different types of cell monolayer are shown to exhibit robust conformal invariance that belongs to the percolation universality class.

  • Bacteria are able to move as vast, dense collectives. Here the authors show that slow movement is key to this collective behaviour because faster bacteria cause topological defects to collide together and trap cells in place.

  • Rod-shaped bacteria are an example of active matter. Here the authors find that a growing bacterial colony harbours internal cellular flows affecting orientational ordering in its interior and at the boundary. Results suggest this system may belong to a new active matter universality class.
