    Water droplets skid across hot surfaces, hovering imperceptibly as they undergo rapid vaporization. Elastic solids are now shown to exhibit a variant of this behaviour, engaging in sustained bouncing by coupling vapour release to elastic deformation.

    The pseudogap is an elusive state that is believed to play an important role in the mechanism for high-temperature superconductivity. A torque-magnetometry study of YBCO reveals that its onset is associated with a second-order nematic transition.

    The 2D electron gas has long been a popular physical system. Now, experiments with GaAs/AlGaAs heterostructures have revealed phases displaying negative permittivity, due to an attractive exchange-correlation energy competing with Coulomb repulsion.

    The anomalous Nernst effect is usually associated with ferromagnets — enabling a temperature gradient to generate a transverse electric field — but the Berry curvature associated with Weyl points can drive this phenomenon in chiral antiferromagnets.

    A hidden stripe-type charge ordering in multilayer iron selenide films on strontium titanate, resembling that in high-temperature cuprate superconductors, could help to explain the complex behaviour of this unusual iron-based superconductor.

    Ensuring topological protection of the edge states in candidate topological insulators is complicated by the need to break time-reversal symmetry. Polar active liquids present an innovative solution to this problem, as a new metamaterial design shows.

    Topological states of matter offer new opportunities to improve the way we transmit acoustic or optical signals, but existing technologies have proven difficult to scale. The field of active metamaterials may be able to help.

    In three-dimensional metals, topological objects known as Weyl nodes can arise from a crossing of the conduction and valence bands. Experiments under high magnetic fields show how Weyl nodes of opposite chiralities can move together to annihilate.

    In different applications the Gouy phase is used to describe broadband lasers, but new 3D measurements of the spatial dependence of a focused laser pulse show serious deviations from the Gouy phase.

    An experimental study of the rare-earth intermetallic system LuPt2In reveals a strong enhancement of superconductivity near the charge density wave quantum critical point. This represents an unusual counter-example to cuprates, in which superconductivity and charge density waves tend to compete.

    The role of physicists in finance is changing, as quantitative trading opens an exciting alternative to traditional financial modelling, and data science lures would-be 'quants' away. But the void is being steadily filled by a new type of analyst.
