Abstract Recent advances in microelectromechanical systems (MEMS) have advanced inertial sensor technology. For resonant gyroscopes, sensitivity scales with the maximum velocity of the resonating mass, as higher velocities amplify the Coriolis force for faster and more accurate inertial signal detection—critical in navigation applications. Conventional MEMS remain in linear regimes, with velocities typically below 5 m/s.

Abstract Ising machines—comprising dissipatively coupled nodes capable of emulating the behaviour of ferromagnetic spins—can form analogue computing engines that surpass the sequential processing constraints of von Neumann architectures. However, the incorporation of Ising dynamics into radio-frequency wireless technologies remains limited, especially in terms of their potential to enhance wireless sensing capabilities.

Editor’s summary Demography is critical for understanding how genetic variation has moved through time and space, and thus the selective and stochastic forces involved. However, these patterns are difficult to determine from modern genomes alone because different scenarios can result in similar genomic outcomes. Grundler et al. created a method using ancestral recombination graphs to trace the spatiotemporal history of DNA segments shared between modern humans (see the Perspective by Gravel).
