Although human beings have known about the phenomenon of "flocking"- that is, the coherent movement of large numbers of creatures (flocks of birds, schools of fish, herds of woolly mammoths, etc.)- since prehistoric times, it is only in the last two decades that we have begun to truly understand this phenomenon. In particular, the surprising fact that a very large collection of organisms in two dimensions cannot all {\it point} in the same direction, but can quite easily {\it move} in the same…

The collective behavior of active agents, whether herds of wildebeest or microscopic actin filaments propelled by molecular motors, is an exciting frontier in biological and soft matter physics.

Coherent ﬂows of self-propelled particles are characterized by vortices and jets that sustain chaotic ﬂows, referred to as active turbulence. Here, we reveal a transition between defect-free active
The fluid mechanics of active materials, built around the idea of living systems as condensed matter made of free-energy-consuming particles, gives insight into biology and opens new directions in
