  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 +...

  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：The Turkana pastoralists of Kenya inhabit arid, water-limited environments and rely largely on livestock for subsistence. Working with Turkana communities, we sequenced 367 whole genomes and identified eight regions with evidence for recent positive selection. One of these regions includes a putative regulatory element for STC1-a kidney-expressed gene involved in metabolism and the response to dehydration. We show that STC1 is induced by antidiuretic hormone in human cells, is associated with ...
