摘要：Rhombohedral (ABC)-stacked graphene has emerged as a platform for exploring correlated and topological physics. However, its large-scale, pure-phase synthesis has been hindered by intrinsic thermodynamic metastability and kinetic instability. In this work, we introduce a step geometry-guided epitaxial strategy to deterministically control interlayer slip, enabling the synthesis of pure-phase rhombohedral graphene. Using this approach, we obtained pure (phase purity > 99%) rhombohedral graphene...

摘要：Invasive alien species (IAS) are a major threat to biodiversity, yet their impact distribution remains poorly understood. Global biodiversity assessments suggest the highest impacts in wealthy countries of the Global North, but this is only inferred from IAS numbers, reflecting research bias. Using a new global database of standardized impact measures, we calculated average impact severity per country and found that it is higher in the Global South despite more than twice as many reports in th...

摘要：Theory predicts that a planet with a sufficiently strong magnetic field orbiting close to its host star could induce star-planet magnetic interactions. This is potentially observable as an optical or radio stellar activity signal synchronized with the planet's orbital period. We analyzed 18 years of high-resolution optical spectroscopy of GJ 436, a low-mass star orbited by a Neptune-sized exoplanet on a polar eccentric orbit. Stellar activity indicators show enhancements at a period correspond...

摘要：Heart failure is a leading cause of morbidity and mortality, yet gene-regulatory mechanisms driving cell type-specific pathologic responses remain undefined. Here, we present the cell type-resolved transcriptomes, chromatin accessibility, histone modifications, and chromatin organization of 13 nonfailing and 23 failing human hearts across all cardiac chambers. Integrative analyses revealed dynamic changes in cell type composition, gene-regulatory programs, and chromatin organization, particula...
