  摘要：Anopheles funestus s.s. is a major human malaria vector across Africa. To study its evolution, especially under vector control pressure, we sequenced 656 modern specimens (collected 2014 to 2018) and 45 historic specimens (collected 1927 to 1967) from 16 African countries. Despite high genetic diversity, the species shows stable but considerable continental population structure. Although one population showed little differentiation over a century and 4000 kilometers, nearby, we found two genet...

  摘要：Hydrogen absorption and desorption in solids are pivotal reactions involved in batteries and hydrogen storage devices. However, conventional thermodynamic and electrochemical hydrogen storage using high-capacity materials suffers from high hydrogen-desorption temperatures and instability of electrolytes. In this work, we explored electrochemical hydride ion (H-)-driven hydrogen storage and developed a solid electrolyte, anti-alpha-AgI-type Ba0.5Ca0.35Na0.15H1.85, which exhibits excellent H- co...

  摘要：Pressures from human activities are expected to increase substantially, affecting marine ecosystems globally. To plan for a sustainable future, we need to forecast the distributions of cumulative effects from multiple pressures. Here, we mapped (at 10-kilometer resolution) the future cumulative impacts of 10 climate, land-based, fishing, and other pressures on 20 marine habitats under two climate scenarios at mid-century (around 2050). We found that cumulative impacts are projected to increase...

  摘要：Manipulating the motion of macroscopic objects near their quantum mechanical uncertainties has been desired in diverse fields, including fundamental physics, sensing, and transducers. Despite progress in ground-state cooling of a levitated solid particle, realizing its nonclassical states has been elusive. Here, we demonstrate quantum squeezing of the motion of a single nanoparticle by rapidly varying its oscillation frequency. We reveal appreciable narrowing of the velocity variance to -4.9 +...
