  摘要：Global overturning circulation partitions the deep ocean into regions, each with different physicochemical characteristics, but the extent to which these water masses represent distinct ecosystems remains unknown. In this work, we integrate extensive genomic information with hydrography and water mass age to delineate microbial taxonomic and functional boundaries across the South Pacific. Prokaryotic richness steeply increases with depth in the surface ocean, which forms a so-called phylocline...

  摘要：Organic self-assembled molecules (SAMs), which are widely used in perovskite solar cells (PSCs), should exhibit enhanced performance to support the ongoing advancement of perovskite photovoltaics. We designed diradical SAMs through a coplanar conjugation of a donor-acceptor strategy to facilitate hole transport across the SAMs. The diradical SAMs exhibited high photothermal and electrochemical stability as well as improved assembly uniformity and large-area solution processability attributed t...

  摘要：Why river channels confine flow to a single pathway or divide flow into multiple interwoven pathways (threads) forms a long-standing fundamental question in river science, which to date remains poorly understood. In this study, we probed channel-pattern origins by mapping thread dynamics along 84 rivers from 36 years of global satellite imagery using particle image velocimetry. Results show that single-thread channels originate from a balance between lateral erosion and accretion, which enable...

  摘要：A portion of fluids subducted in an oceanic plate is thought to return to Earth's surface and has the potential to influence faulting during that migration. We used machine learning to detect and locate earthquakes in the northeast Japan forearc using data from a cabled ocean-bottom seismic network. That seismicity shows vertical distributions extending from the subducted plate to near the sea floor. The forearc seismic belt corresponds to the seismicity assumed to result from fluid supply fro...
