Most swimming bacteria are capable of following gradients of nutrients, signaling molecules
and other environmental factors that affect bacterial physiology. This tactic behavior became …

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 …

Bacterial swarming is a collective mode of motion in which cells migrate rapidly over
surfaces, forming dynamic patterns of whirls and jets. This review presents a physical point …

Bacterial swarming is a rapid mass-migration, in which thousands of cells spread collectively
to colonize surfaces. Physically, swarming is a natural example for active particles that use …

Bacteria organize in a variety of collective states, from swarming—rapid surface exploration,
to biofilms—highly dense immobile communities attributed to stress resistance. It has been …

While bacterial swarms can exhibit active turbulence in vacant spaces, they naturally inhabit
crowded environments. We numerically show that driving disorderly active fluids through …

Meso-scale turbulence was originally observed experimentally in various suspensions of
swimming bacteria, as well as in the collective motion of active colloids. The corresponding …

At high cell density, swimming bacteria exhibit collective motility patterns, self-organized
through physical interactions of a however still debated nature. Although high-density …

We report the numerical evidence of a new state of bacterial turbulence in confined
domains. By means of extensive numerical simulations of the Toner-Tu-Swift-Hohenberg …

Modeling cancer cells is essential to better understand the dynamic nature of brain tumors
and glioma cells, including their invasion of normal brain. Our goal is to study how the …
