TL;DR: The authors' simulations suggest that both the suppression of phase separation and the self-assembly of rotors are generic features of aggregating swimmers and should therefore occur in a variety of biological and synthetic active particle systems.

TL;DR: This work measures the swimming speed distribution and motile cell fraction in Escherichia coli suspensions and finds that the diffusivity of nonmotile cells is enhanced in proportion to the concentration of motile cells.

TL;DR: The current standard model of how bacteria propelled by rotary helical flagella swim through concentrated polymer solutions postulates bacteria-sized pores, allowing them relative easy passage is overturned, and clear evidence for non-Newtonian effects in the highest-molecular-weight PVP solution is found.

TL;DR: A fast, high-throughput method for characterizing the motility of microorganisms in three dimensions based on standard imaging microscopy by analyzing the spatiotemporal fluctuations of the intensity in the sample from time-lapse images and obtaining the intermediate scattering function of the system.

TL;DR: It is shown that the diffusivity of nonmotile cells in a three-dimensional (3D) population of motile E. coli is enhanced by an amount proportional to the active cell flux, indicating that fluid entrainment is not relevant for diffusion enhancement in 3D.
