    Stress relaxation in cell monolayers shows remarkable similarities with that of single cells, suggesting the rheology of epithelial tissues is mediated by the actomyosin cortex—with dynamics reminiscent of those on a cellular level.

    The decay asymmetry and helicity phase of polarized baryon–antibaryon pairs are measured at the BESIII experiment, testing charge–parity symmetry and revealing a discrepancy of the Λ →  decay asymmetry with respect to the current world average.

    High-resolution experiments attribute surprisingly large forces to the molecular motors helping a cell sense its surroundings. A two-state theory interprets the contractile properties of these motors as emergent features of their collective behaviour.

    When a wound heals, different types of branched and bundled actin structure form, each designed to perform a specific function. Experiments and theory now suggest that the actin architecture depends on the stiffness of the cell’s surroundings.

    A continuous version of the Maxwell demon is a machine that repeatedly monitors a system, but extracts work only on state change. Arbitrarily large quantities of work can thus be extracted, as demonstrated by DNA hairpin pulling experiments.

    Rich data are revealing that complex dependencies between the nodes of a network may not be captured by models based on pairwise interactions. Higher-order network models go beyond these limitations, offering new perspectives for understanding complex systems.

    By tuning the geometry of a two-dimensional sonic crystal, its one-dimensional helical edge states become gapped and zero-dimensional topological corner states emerge. The band topology is thus manifested in a hierarchy of dimensions.

    The same type of polymer network deforms cell membranes inward, to absorb external material, and outward, to facilitate signal transmission. Experiments and theory show that these deformations are regulated by membrane tension and network mesh size.

    A scattering resonance associated with quasi-bound diatomic levels trapped behind the centrifugal barrier has been observed in a quantum-degenerate potassium gas. Various measurements reveal the d-wave character of the collisions.

    The difference between the β-decay rate predicted for free neutrons and that measured in real nuclei is explained by first-principles calculations to arise from strong correlations and the weak-force coupling between nucleons.

    Bacteria and other helical microswimmers are known to swim faster in non-Newtonian fluids. Coarse-grained simulations suggest the increase may be due to a polymer depletion effect near the body and flagellum, inducing a slip velocity at the surface.

    A graphene-like two-dimensional sonic crystal, under uniaxial deformation, experiences a giant uniform pseudomagnetic field. This leads to the quantization of the cyclotron orbits—a kind of acoustic Landau level—that is observed here.

    Inelastic neutron scattering is used to probe the spin dynamics of molecular nanomagnets, but extensive supporting computations make the technique challenging. Proof-of-principle experiments now show that quantum computers may solve these computations efficiently.

    Collagen networks go from soft to rigid when strained, but in tissue they exist in a soft matrix. An enhanced stiffness and delayed strain-stiffening is now revealed in the composite, which may explain the remarkable sensitivity of living tissue.

    The quantum Hall effect is thought to exist only in two-dimensional materials. Here, transport measurements show that thin graphite slabs have a 2.5-dimensional version, with a parity effect for samples with odd and even number of layers.

    In the early Universe, fluctuations in the neutrino density produced a distinct shift in the temporal phase of sound waves in the primordial plasma. The size of this phase shift has now been constrained through baryon acoustic oscillation data.
