We review recent work on active colloids at interfaces, including self-propelled colloids that
move by generating a propulsive force, and driven colloids that move under external fields …

Microrotors are microscopic objects that convert energy stored in the environment into
spontaneous rotation, in the form of spinning along an axis, rolling on a surface, or orbiting …

Vegetation Turing patterns play a critical role in the ecological functioning of arid and semi‐
arid ecosystems. However, the long-range spatial features of these patterns have been …

Chiral active matter comprises particles which can self-propel and self-rotate. Examples
range from sperm cells and bacteria near walls to autophoretic L-shaped colloids. In this …

Vortical flows of rotating particles describe interactions ranging from molecular machines to
atmospheric dynamics. Yet to date, direct observation of the hydrodynamic coupling …

Broken time-reversal and parity symmetries in active spinner fluids imply a nondissipative
“odd viscosity,” engendering phenomena unattainable in traditional passive or active fluids …

Large density fluctuations observed in active systems and hyperuniformity are two
seemingly incompatible phenomena. However, the formation of hyperuniform states has …

We report on the emergence of spontaneously rotating clusters in active emulsions.
Ensembles of self-propelling droplets sediment and then self-organise into planar …

Chiral active matter is enjoying a rapid increase of interest, spurred by the rich variety of
asymmetries that can be attained in, eg, the shape or self-propulsion mechanism of active …

Spatial self-organization of ecosystems into large-scale (from micron to meters) patterns is
an important phenomenon in ecology, enabling organisms to cope with harsh environmental …
