    Whether spatial order is required for structures that support topological modes remains unclear. Amorphous arrangements of interacting gyroscopes suggest that topology arises in materials for which the only design principle is the local connectivity.

    Stanene is a single sheet of tin atoms. Here, it is shown that a few stacked layers of stanene can be a superconductor. Changing the thickness of the substrate modifies the form of superconductivity and critical temperature.

    Turbulence in pipe flows causes substantial friction (and therefore economic) losses. An experimental and numerical study now shows a solution might be to initially enhance turbulent mixing, which subsequently leads to a collapse of turbulence.

    Turbulence in pipe flows causes substantial friction and economic losses. The solution to appease the flow through pipelines might be, counterintuitively, to initially enhance turbulent mixing and get laminar flow in return.

    Enabled by recent advances in symmetry and electronic structure, researchers have observed signatures of unconventional threefold degeneracies in tungsten carbide, challenging a longstanding paradigm in nodal semimetals.

    Triply degenerate electronic structure—three-component fermions—protected by crystal symmetries is observed in tungsten carbide. The observed Fermi arcs associated with the surface states provide evidence of the non-trivial topology of the states.

    Technological innovation seems to be dominated by chance. But a new mathematical analysis suggests we might be able to anticipate when seemingly useless technologies become keystones of more complex environments.

    As we move beyond the twentieth anniversary of the teleportation of a quantum state, it's clear that the coming years will be just as fruitful.

    It seems obvious that restricting travel should help prevent the surge of epidemics. But a new mathematical analysis now demonstrates that mobility often reduces the heterogeneity in population distributions, thereby lowering the epidemic risk.

    Non-equilibrium signatures of topology—the appearance, movement and annihilation of vortices in a cold-atom system—are identified, showing that topological phase can emerge dynamically from a non-topological state.

    Nanomagnets are often used to build artificial systems that are geometrically frustrated, but when quasiperiodic ordering is introduced, an unusual ground state can form, with an ordered skeletal structure surrounding groups of degenerate macrospins.
