  摘要：Foreshock activity is a key consideration in traffic-light protocol (TLP) to mitigate seismic risk from injection-induced earthquakes (IIEs). However, the seismogenic processes of IIE foreshocks remain poorly understood. Using an enhanced western Canada catalog (2014-2024), we analyzed 77 IIE sequences to statistically delineate foreshock patterns before local magnitude (ML) >= 3 mainshocks. We found that 92% are preceded by foreshocks and that foreshock productivity and spatiotemporal pattern...

  摘要：Viruses are intracellular parasites that reprogram the host proteome to promote replication and evade immune recognition. We applied a virome-wide library of similar to 10,000 open reading frames to discover viral ubiquitin ligases, mapping their mechanisms of degradation and host substrates using targeted CRISPR screens and proteomics. These viral effectors could be classified as canonical ligases that mimic host E3s, hijackers that redirect host E3s, and noncanonical ligases that rewire cull...

  摘要：Textured piezoelectric ceramics could deliver the ultrahigh piezoelectricity of single crystals while retaining the mechanical robustness and cost-effectiveness of conventional ceramics, but after decades of effort, their piezoelectricity has not approached that of single crystals. We exploited compositional flexibility of textured ceramics, a critical advantage over single-crystal counterparts, using a machine-learning approach. Our samarium (Sm)-doped Pb(In1/2Nb1/2)O3-Pb(Sc1/2Nb1/2)O3-PbTiO3...

  摘要：Characterizing the factors that have shaped linguistic diversity is fundamental for understanding human history, culture, and cognition. In this study, we combined statistical and social computational modeling, ethnographic data, and paleodemographic inference to model trajectories of global linguistic diversity. Before the onset of plant and animal domestication, the number of languages was smaller than it is today (4500 to 6000 compared with 7500). Subsequent increases in global population p...

  摘要：Teeth define mammalian evolution, and one of many adaptive dental breakthroughs in crown mammals is the tribosphenic molar: a tooth with a dual shearing-crushing function, often considered a key adaptation in crown mammals. However, we do not know how potential trade-offs between these antagonistic functions may influence the macroevolutionary outcomes of mammalian lineages. Here, we show that predatory mammals evolved dichotomized performance in their tribosphenic carnassial teeth, with slici...
