Understanding the precise role of hydrodynamic interactions in the self-organization of circle-swimming active matter is an exciting avenue. Here, in a mixture of counter-rotating disks, the authors show that phase separation formed the largest size structure directly, without domain coarsening, and is driven by the inverse cascade phenomena characteristic of 2D turbulence.
