  摘要：Nonvolatile memories should store information reliably while consuming little energy. Ferroelectric tunnel junctions offer compact readout, but conventional ionic displacement ferroelectrics can fatigue, and two-dimensional sliding ferroelectrics are robust but generate weak readout in two terminal devices. We engineered a van der Waals junction using rhombohedral molybdenum disulfide, hexagonal boron nitride, monolayer graphene, and chromium. This architecture converts small sliding polarizat...

  摘要：The mouse Y chromosome is essential for male reproduction, yet the GRCm39 reference contains 25 gaps, particularly in repetitive and complex regions. Here, we assembled a telomere-to-telomere Y chromosome (mT2T Y) of 95.21 Mb from a C57BL/6 mouse incorporating parental genomes. This assembly fills all gaps, corrects structural errors, and adds over 8.70 Mb of previously unassembled sequence to the reference genome. We annotated 142 previously unidentified genes, identified Y specific satellite...

  摘要：Cell entry of nonenveloped animal viruses requires translocation of a macromolecular assembly across a cellular membrane. Double-stranded RNA viruses introduce into the target cell an inner capsid particle that does not uncoat further. Instead, it extrudes capped viral mRNA by virtue of polymerase and capping activities within it. As described here, we used cryogenic electron tomography to visualize the full course of rhesus rotavirus entry, from cell attachment and virion uptake to release of...
• Hydroclimatic-driven pulse enrichment amplifies riverine microplastic export in developing countries AI翻译

  摘要：Rivers are key conduits in the global microplastic cycle, but how much they export to ` ocean and what controls this export remain unresolved. Here, we present a global daily dataset of riverine microplastic concentrations and exports and find that rivers delivered far more microplastics to the ocean than most previous estimates suggest. Ninety-six percent of this export originated in the Global South, with Southeast and East Asia contributing >50% of the total flux. Furthermore, similar to 70...

  摘要：Obesity increases breast cancer risk and tumor aggressiveness, yet the mechanisms underlying this association remain unclear. In this work, we identify a tumor-suppressive lipid signaling pathway in which mammary adipocytes secrete the oxylipin 9S-hydroxyoctadecadienoic acid (9S-HODE). 9S-HODE induces ferroptosis in breast cancer cells by disrupting iron homeostasis. Adipocytes in obese mammary tissue produce less 9S-HODE, and tumors in obese mice exhibit reduced ferroptosis. Accordingly, ferr...
