Active fluids exhibit spontaneous flows with complex spatiotemporal structure, which have
been observed in bacterial suspensions, sperm cells, cytoskeletal suspensions, self …

A wide range of experimental systems including gliding, swarming and swimming bacteria,
in vitro motility assays, and shaken granular media are commonly described as self …

Fluid dynamics plays a crucial role in many cellular processes, including the locomotion of
cells such as bacteria and spermatozoa. These organisms possess flagella, slender …

Pair interactions between active particles need not follow Newton's third law. In this work, we
propose a continuum model of pattern formation due to nonreciprocal interaction between …

Active matter consists of units that generate mechanical work by consuming energy.
Examples include living systems (such as assemblies of bacteria,,–and biological tissues,) …

Bacteria are among the oldest and most abundant species on Earth. Bacteria successfully
colonize diverse habitats and play a significant role in the oxygen, carbon, and nitrogen …

Self-sustained turbulent structures have been observed in a wide range of living fluids, yet
no quantitative theory exists to explain their properties. We report experiments on active …

Individual swimming bacteria are known to bias their random trajectories in search of food
and to optimize survival. The motion of bacteria within a swarm, wherein they migrate as a …

Bio-mechanical hybrids are an emerging class of engineered composite soft materials with
the ability to move and reconfigure their structure and properties in response to external …

Concentrated suspensions of swimming microorganisms and other forms of active matter
are known to display complex, self-organized spatiotemporal patterns on scales that are …
