    Smells like teen physics

    The number 15 is created by quantum imaging, self-assembly of green-fluorescent-protein-active Escherichia coli bacteria, self-assembly of polystyrene beads and with a quantum gas microscope.

    Braided anyons

    An interferometer device is used to detect the quantum-mechanical phase that is gained when two anyons are braided around each other. The fractional value of the phase proves that these quasiparticles are neither bosons nor fermions.

    Chasing Majorana rainbows

    The interface between a quantum Hall state and a superconductor hosts topological modes. Here, interference between two such modes turns an electron into either a hole or an electron depending on the phase difference along the interference path.

    Indirect-drive fast ignition

    Experiments realizing the indirect-drive fast ignition scheme for inertial confinement fusion are reported. Enabled by a tightly compressed target, an increase of neutron yield is observed.

    Turbulence in starfish egg cells

    Activity in certain living systems can lead to swirling flows akin to turbulence. Here, the authors connect the dynamics of topological defects in starfish oocyte membranes to vortex dynamics in 2D Bose–Einstein condensates.

    A liquid of magnetic multipoles

    A detailed neutron-scattering study reveals a quantum spin liquid behaviour in Ce2Sn2O7 originating from its higher-order magnetic multipolar moments acting on the geometrically frustrated pyrochlore lattice.

    Glassy learning

    The physics that underlies the glass transition is both subtle and non-trivial. A machine learning approach based on graph networks is now shown to accurately predict the dynamics of glasses over a wider range of temperature, pressure and density.

    Oddly synchronised

    An experiment with three alternating-current generators demonstrates converse symmetry breaking — a phenomenon whereby the system achieves frequency synchronization when its component systems are tuned asymmetrically.

    Charge on the bouncing barrier

    In our understanding of planetary formation, it is still unclear how millimetre-sized dust grains grow into centimetre-sized aggregates. Microgravity experiments now show that electrical charging of the grains leads to the formation of larger clumps.

    Light-induced anomalous Hall effect

    A transient topological response in graphene is driven by a short pulse of light. When the Fermi energy is in the predicted band gap the Hall conductance is around two conductance quanta. An ultrafast detection technique enables the measurement.
