  摘要：Social networks scaffold the diffusion of information on social media. Much attention has been given to the spread of true vs. false content on online social platforms, including the structural differences between their diffusion patterns. However, much less is known about how platform interventions on false content alter the engagement with and diffusion of such content. In this work, we estimate the causal effects of Community Notes, a novel fact-checking feature adopted by X (formerly Twitt...

  摘要：Microscale symbioses can be critical to ecosystem functions, but the mechanisms of these interactions in nature are often cryptic. Here, we use a combination of stable isotope imaging and tracing to reveal carbon (C) and nitrogen (N) exchanges among three symbiotic primary producers that fuel a salmon-bearing river food web. Bulk isotope analysis, nanoSIMS (secondary ion mass spectrometry) isotope imaging, and density centrifugation for quantitative stable isotope probing enabled quantificatio...

  摘要：The Gulf of Panama's (GOP) seasonal upwelling system has consistently delivered cool, nutrient-rich waters via northerly trade winds every January-April for at least 40 y. Here, we document the failure of this normally highly predictable phenomenon in 2025. Data suggest that the cause was a reduction in Panama wind-jet frequency, duration, and strength, possibly related to the Intertropical Convergence Zone (ITCZ) position during the 2024-2025 La Ni & ntilde;a, though the mechanisms remain unc...
• miR444b.2-HsfA1-AOC1 module mediates heat priming-enhanced blast resistance in rice AI翻译

  摘要：As global climate change exacerbates extreme heat events, the interplay between heat stress and blast disease resistance in rice remains poorly understood. In this study, through integrated transcriptome profiling and systematic phenotyping of mutants in several thermosensory pathways, we identified HsfA1 as a positive regulator of heat priming-enhanced blast resistance in rice. Systematic analysis of microRNA (miRNA) dynamics, bioinformatics prediction, and RNA pull-down experiments revealed ...

• Interfacial electroneutrality controls transport of asymmetric salts through charge-patterned mosaic membranes AI翻译

  摘要：Membranes that selectively enhance target solute permeation while rejecting competing species are essential for precision separations. This study introduces charge-patterned mosaic membranes (CMMs) that selectively transport divalent asymmetric salts by leveraging a net-neutral membrane-solution interface. This mechanism, dictated by the charge ratio of positive and negative domains on the membrane surface and the balance of cations and anions in the salt, is supported by analytical, numerical...

  摘要：Bacteria have several nucleotide second messengers, most of which act as global regulators to control a wide range of bacterial physiological processes. Studies usually focus on a single second messenger, and the mechanisms and physiological significance of the cross-regulation between different nucleotide second messengers are often unclear. Here, we show that Shewanella putrefaciens can form biofilms in both nutrient-rich and nutrient-poor media. While both are controlled by c-di-GMP, the re...
