  • It has been previously shown theoretically that the average path length of random walks inside a closed domain is invariant. Here the authors demonstrate that this invariance property can be used to predict the mean residence time of swimming bacteria exploring structured micro-environments.

  • Most biological and artificial self-propelled particles tend to be attracted by solid walls on their swimming pathways. Vizsnyiczai et al. show that, unexpectedly, confining E. coli cells inside a channel triggers stable locomotion along the channel axis once the channel is narrower than a critical value.

  • Colloidal solids have provided insights into complex condensed matter phenomena like 2D melting transitions and glass dynamics. Here, the authors explore active solids, revealing that a magnetic colloidal crystal activated by light-driven bacteria exhibits multiple effective temperatures and a new active melting route.

  • The mechanical forces exerted by active fluids may provide an effective way of transporting microscopic objects, but the details remain elusive. Using space modulated activity, Pellicciotta et al. generate active pressure gradients capable of transporting passive particles in controlled directions.

  • Bacteria are able to propel themselves and thus drive systems out of equilibrium. Here the authors aim to control this motion and exploit it in microengineered motors which are powered by genetically modified bacteria and driven by light.

  •  Light can be used to precisely modulate the speed of active particles in space and time. Here, the authors rectify and confine bacteria using an optical feedback loop that couples bacteria topast configurations.
