  • Molecular chirality can be used to control interfacial tension in multi-component mixtures of chiral molecules, and tuning the chirality makes it possible to produce and manipulate self-assembling complex chiral structures.

  • Experiments and coarse-grained simulations show, in an active system based on microtubules, a system-spanning phase of motile defects with orientational order that persists over hours despite a defect lifetime of seconds.

  • Soft filamentous bundles, including F-actin, microtubules or bacterial flagella, can experience large frictional forces that scale logarithmically with sliding velocity, and such frictional coupling can be tuned by modifying lateral interfilament interactions.

  • The self-regulation of self-assembled systems is well understood for non-responsive systems, but responsive systems are less studied. Here, the authors report the development of a stimuli-responsive, self-regulating assembly of chiral and magnetically responsive nanorods, with control over the chirality of the system.

  • The field of active matter studies how internally driven motile components self-organize into large-scale dynamical states and patterns. This Review discusses how active matter concepts are important for understanding cell biology, and how the use of biochemical components enables the creation of new inherently non-equilibrium materials with unique properties that have so far been mostly restricted to living organisms.

  • The rational design of out-of-equilibrium demixing transitions remains challenging. Active fluids are used to control the liquid–liquid phase separation of passive DNA nanostars and establish the activity-based control of the phase diagram.

  • In a model system crosslinked by motors, cytoskeletal polymers slide past each other at speeds independent of their polarity. This behaviour is best described within an active-gel framework that deviates from the dilute limit set by existing theory.

  • Active matter exhibits positional coherence in addition to the well-known orientational order. It is now shown that coherent structures in active nematics—made of dynamical attractors and repellers—form, move and deform, steered by topological defects.

  • Conventional coalescence at fluid drop and bubble interfaces follows the all-or-none rule. Zakhary et al. show that the coalescence between colloidal membranes composed of aligned rod-like viruses does not follow this rule, but exhibits an intermediate state induced by topological defects.

  • DNA origami allows the design of rod-shaped particles with specific geometrical features. This is exploited to examine how particle-level characteristics affect properties of the bulk phase and the superstructures such colloids assemble into.

  • Active materials are hierarchically assembled, starting from extensile microtubule bundles, to form emulsions with unexpected collective biomimetic properties such as autonomous motility.
