TL;DR: In this paper, the authors combine experiments, particle simulations, and continuum theory to identify the statistical properties of self-sustained meso-scale turbulence in active systems, and propose a minimal continuum model for incompressible bacterial flow.

TL;DR: How the spatial arrangement of genotypes within a community influences the cooperative and competitive cell–cell interactions that define biofilm form and function is discussed.

TL;DR: Direct measurements of the bacterial flow field generated by individual swimming Escherichia coli both far from and near to a solid surface are reported, implying that physical interactions between bacteria are determined by steric collisions and near-field lubrication forces.

TL;DR: This study prepares synthetic molecules and analyzes them for inhibition of the Pseudomonas quorum-sensing receptors LasR and RhlR to demonstrate the potential for small-molecule modulators of quorum sensing as therapeutics.

TL;DR: Velocimetry of bacteria and surrounding fluid, determined by imaging cells and tracking colloidal tracers, yields consistent results for velocity statistics and correlations over 2 orders of magnitude in kinetic energy, revealing a decrease of fluid memory with increasing swimming activity and linear scaling between kinetic energy and enstrophy.
