    A local driving mechanism for solitons that accelerates both solitons and antisolitons in the same direction, called non-reciprocal driving, is introduced, showing a subtle interplay between non-reciprocity and topological solitons and providing waveguiding and wave-processing possibilities for other fields.

    We demonstrate an all-optical, mode-locking, Kerr-comb frequency division method that provides a chip-scale microwave source that is extremely versatile, accurate, stable and has ultralow noise, using only a single continuous-wave laser.

    Analyses of virological and surveillance data in France show that a substantial proportion of symptomatic cases of COVID-19 have remained undetected and that easily accessible and efficient testing is required to control the pandemic.

    Manipulation of the effective gravity of an oscillating liquid creates stable buoyancy in the lower surface of a liquid layer levitating above air, allowing bodies to float upside down.

    A superconducting diode that has zero resistance in only one direction is realized in an artificially engineered superlattice without inversion symmetry, enabling directional charge transport without energy loss.

    Microfluidic systems controlled by a single driving pressure are programmed to exhibit complex flow-switching schemes and a fluid analogue of Braess’s paradox by exploiting fluid inertia and network design.

    Analysis of a dataset of high-sensitivity Tohoku–Hokkaido seismograph records shows that pairs of subduction-type earthquakes of different sizes have very similar initial characteristics, implying that the final size of an earthquake cannot be reliably predicted from these.

    The thermal vibrations of a carbon nanotube are directly measured in real time with high displacement sensitivity and fine time resolution, revealing dynamics undetected by previous time-averaged measurements.

    The domain-wall structure and dynamics are found to enhance, rather than inhibit, the high-frequency performance of an intrinsically tunable material, obtaining ultralow loss and exceptional frequency selectivity.

    A relaxation oscillator incorporating nanoscale niobium dioxide memristors that exhibit both a current- and a temperature-controlled negative differential resistance produces chaotic dynamics that aid biomimetic computing.

    A mesoscopic cellular automaton arising from a microscopic reaction–diffusion system as a function of skin thickness is observed in ocellated lizards, showing that cellular automata are not merely abstract computational systems, but can directly correspond to processes generated by biological evolution.

    Ablation cooling is demonstrated as an effective means of removing material using successive bursts of laser pulses with short intraburst delay times; the technique allows the overall pulse energy to be decreased, overcoming negative thermal effects during the ablation process.

    Molecular dynamics simulations of 90° domain walls in PbTiO3 are used to construct a nucleation-and-growth-based analytical model that quantifies the dynamics of many types of domain walls in various ferroelectrics, suggesting intrinsic domain-wall motion as a universal mechanism for ferroelectric switching.

    An analytical framework is proposed for a complex network to accurately predict its dynamic resilience and unveil the network characteristics that can enhance or diminish resilience.

    A particle accelerator that is two orders of magnitude more efficient than conventional radio-frequency accelerators is described in which positrons (rather than electrons) at the front of a bunch transfer their energy to a substantial number of positrons at the rear of the same bunch by exciting a wakefield in the plasma.
