    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.

    While Bose–Einstein condensates of atoms were achieved in the mid-1990s, extending the regime of quantum degeneracy to polar molecules took another two decades of dedicated work. The researchers that contributed to this achievement span many generations of students in many different laboratories around the world.

    The transport properties of many two-dimensional systems are strongly affected by the proximity of a periodic pattern. Colloidal particles are now shown to have preferred sliding routes due to competing symmetries between two unmatched crystalline surfaces.

    Machine learning techniques have latterly gained currency in condensed-matter physics, for example by identifying phase transitions. An unsupervised machine learning algorithm that identifies topological order is now demonstrated.

    A measurement based on quantum entanglement of the parameter describing the asymmetry of the Λ hyperon decay is inconsistent with the current world average. This shows that relying on previous measurements can be hazardous.

    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.
