Collective behaviour defines the lives of many animal species on the Earth. Underwater
swarms span several orders of magnitude in size, from coral larvae and krill to tunas and …

Collective motion is ubiquitous in nature; groups of animals, such as fish, birds, and
ungulates appear to move as a whole, exhibiting a rich behavioral repertoire that ranges …

A variety of organisms exhibit collective movement, including schooling fish and flocking
birds, where coordinated behavior emerges from the interactions between group members …

A widely mentioned but not experimentally confirmed view (known as the 'criticality
hypothesis') argues that biological swarm systems gain optimal responsiveness to …

Autonomous out-of-equilibrium agents or cells in suspension are ubiquitous in biology and
engineering. Turning chemical energy into mechanical stress, they generate activity in their …

Collective cells, a typical active matter system, exhibit complex coordinated behaviors
fundamental for various developmental and physiological processes. The present work …

One of the hallmarks of the collective movement of large schools of pelagic fish are waves of
shimmering flashes that propagate across the school, usually following an attack by a …

Social animals can use the choices made by other members of their groups as cues in
decision making. Individuals must balance the private information they receive from their …

Real-world non-autonomous systems are open, out-of-equilibrium systems that evolve in
and are driven by temporally varying environments. Such systems can show multiple …

Groups of animals are observed to transmit information across them with propagating waves
or avalanches of behaviour. These behavioral cascades often display scale-free signatures …
