    A liquid droplet is shown to slide across a solid surface subject to friction forces analogous with those between two solids. The phenomenon is generic, and closes a gap in our understanding of liquid–solid friction.

    The simplest lattice model that allows the investigation of superconductivity with attractive interactions is realized using ultracold quantum gas. The experimental observation provides a lower bound on the strength of s-wave pairing correlations.

    Topological defects in a turbulent active nematic on a toroidal surface are shown to segregate in regions of opposite curvature. Simulations suggest that this behaviour may be controlled — or even suppressed — by tuning the level of activity.

    In nanoscale electronic circuits, controlling the flow of heat is essential. A demonstration of a heat Coulomb blockade arising from thermal many-body effects shows that thermal transport follows distinct rules in the quantum regime.

    Proximity effects enable superconductivity to leak into normal metals. In graphene, a Klein-like tunnelling of superconducting pairs from a high-temperature superconductor allows the proximity effects to be tuned by electric fields.

    In a hot, under-dense plasma, eight input beams are combined into a single, well-collimated beam, whose energy is more than triple than that of any incident beam. This shows how nonlinear interactions in plasmas can produce optics beams at much higher intensity than possible in solids.

    The photoactive properties of microalgae are well documented when it comes to photosynthesis and motility. But it seems their adhesion to surfaces can also be manipulated with light, which may serve to optimize their photoactive functionality.
