摘要：Soil organic carbon (OC) sequestration is presumed to rely to a large extent on microbial transformation of plant residues into microbial necromass. Necromass formation, however, represents only one pathway by which microorganisms contribute to soil organic matter, while OC released through metabolism is often neglected. Using a dynamic modeling approach, we show that exudates and waste products contribute about equally to bacterially derived OC inputs to soil with median contributions of 10% ...

摘要：Defensive symbioses in which beneficial microbes protect hosts from natural enemies are ubiquitous across animals and plants, but the underlying mechanisms remain poorly understood. Field surveys and laboratory assays revealed that infection of the invasive whitefly Bemisia tabaci by the bacterial symbiont Rickettsia and plant begomovirus were positively correlated with each other but each negatively correlated with a parasitic fungal infection (Beauveria bassiana) in the host. We show that be...

摘要：Animals employ different strategies for relating sensory input and behavioral output to navigate sensory environments, but what strategy to use, when to switch and why remain unclear. Caenorhabditis elegans navigate by combining steering (small heading changes) with turn (large reorientations). It is unknown whether transitions between these elements are driven solely by sensory input or also by persistent internal states. It is also unclear how worms sometimes appear to exit turns such that t...

摘要：Finite-momentum pairing, exemplified by Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states, represents a paradigmatic form of unconventional superfluidity driven by Fermi-surface mismatch, but its detection in two-dimensional systems has remained elusive. Here we study a doped, spin-imbalanced attractive Hubbard model using a combined experimental and computational approach, based on quantum gas microscopy and constrained-path auxiliary-field quantum Monte Carlo, with direct comparisons showing qu...

摘要：Evolutionary pressure on microbial communities propagating under extreme environmental conditions often results in unique structural adaptations to promote cell survival. Here, we report an investigation of AbpX, a biomatrix protein identified in cultures of the hyperthermophilic archaeon Pyrodictium abyssi. Under ex vivo and in vitro conditions, AbpX assembles into a paracrystalline lattice composed of semiflexible fibrils. CryoEM analysis of recombinant AbpX fibrils reveals that the precurso...

摘要：Accurately predicting mosquito population dynamics in cities requires models that couple climatic sensitivity with urban spatial heterogeneity. We developed a spatially explicit, climate-driven framework that integrates satellite imagery, field observations, and biology to simulate Aedes aegypti dynamics across heterogeneous urban landscapes. A decomposition technique was introduced to disentangle entomological observations from mixed urban sites into landscape-specific time series for houses,...
