  摘要：Numerous correlated many-body phases, both conventional and exotic, have been reported in magic-angle twisted bilayer graphene (MATBG)(1-24). However, the dynamics associated with these correlated states, crucial for understanding the underlying physics, remain unexplored. Here we combine exciton sensing and optical pump-probe spectroscopy to investigate the dynamics of isospin orders in MATBG with WSe2 substrate across the entire flat band, achieving sub-picosecond resolution. We observe rema...

  摘要：Large language models (LLMs) are becoming less overtly racist, but respond negatively to text in African American English. Such 'covert' racism could harm speakers of this dialect when LLMs are used for decision-making.

  摘要：Sterile inflammation after myocardial infarction is classically credited to myeloid cells interacting with dead cell debris in the infarct zone1,2. Here we show that cardiomyocytes are the dominant initiators of a previously undescribed type I interferon response in the infarct borderzone. Using spatial transcriptomics analysis in mice and humans, we find that myocardial infarction induces colonies of interferon-induced cells (IFNICs) expressing interferon-stimulated genes decorating the borde...

  摘要：A much-cited statistic about how much of the world's biodiversity is under Indigenous stewardship is unsupported - and could harm the cause it is meant to support. Credit: Joan de la MallaA man and small child sit together weaving palms in the Bolivian Amazon

  摘要：Tumour innervation is associated with worse patient outcomes in multiple cancers(1,2), which suggests that it may regulate metastasis. Here we observed that highly metastatic mouse mammary tumours acquired more innervation than did less-metastatic tumours. This enhanced innervation was driven by expression of the axon-guidance molecule SLIT2 in tumour vasculature. Breast cancer cells induced spontaneous calcium activity in sensory neurons and elicited release of the neuropeptide substance P (S...
