  摘要：Epigenetic inheritance of silent chromatin domains is fundamental to cellular memory during embryogenesis, but it must overcome the dilution of repressive histone modifications during DNA replication1. One such modification, histone H2A lysine 119 monoubiquitination (H2AK119Ub), needs to be re-established by the Polycomb repressive complex 1 (PRC1) E3 ligase to restore the silent Polycomb domain2,3. However, the exact mechanism behind this restoration remains unknown. Here, combining cryo-elec...

  摘要：The most distant galaxies detected were seen when the Universe was a scant 5% of its current age. At these times, progenitors of galaxies such as the Milky Way were about 10,000 times less massive. Using the James Webb Space Telescope (JWST) combined with magnification from gravitational lensing, these low-mass galaxies can not only be detected but also be studied in detail. Here we present JWST observations of a strongly lensed galaxy at z(spec)=8.2960.001, showing massive star clusters (the ...

  摘要：Nanoscale detection and control of the magnetic order underpins a spectrum of condensed-matter research and device functionalities involving magnetism. The key principle involved is the breaking of time-reversal symmetry, which in ferromagnets is generated by an internal magnetization. However, the presence of a net magnetization limits device scalability and compatibility with phases, such as superconductors and topological insulators. Recently, altermagnetism has been proposed as a solution ...

  摘要：In the quest for environmental sustainability, the rising demand for electric vehicles and renewable energy technologies has substantially increased the need for efficient lithium extraction methods. Traditional lithium production, relying on geographically concentrated hard-rock ores and salar brines, is associated with considerable energy consumption, greenhouse gas emissions, groundwater depletion and land disturbance, thereby posing notable environmental and supply chain challenges.
