  摘要：Caste differentiation involves many functional traits that diverge during larval growth and metamorphosis to produce adults irreversibly adapted to reproductive division of labor. Investigating developmental differentiation is important for general biological understanding and has increasingly been explored for social phenotypes that diverge in parallel from similar genotypes. Here, we use Monomorium pharaonis ants to investigate the extent to which canalized worker development can be shifted ...

  摘要：At the nearly pristine hydrothermal vents of the deep sea, highly endemic animals depend upon bacteria nourished by hydrothermal fluids that emerge as outflows from the seafloor. These animals are remarkable in tolerating extreme conditions, including high heat, toxic reduced sulfide, and low oxygen. Here, we test whether the extreme vent environment has selected for functionally similar species across the world's deep ocean, despite well- established global geographic patterns of high phyloge...

  摘要：The precise control of flowering time is of utmost importance for crop adaptation to varying environmental conditions and consequently determines grain yield and plant fitness. Soybean E2 , the homolog of Arabidopsis GIGANTEA, is a major locus contributing to high- latitude adaptation and is involved in photoperiod sensitivity. However, due to major effects of E2 , additional genetic loci controlling soybean flowering and adaptation have historically been masked and difficult to identify. Here...
• The offline roots of online hostility: Adult and childhood administrative records correlate with individual-level hostility on Twitter AI翻译

  摘要：Reducing hostility in social media interactions is a key public concern. Most extant research emphasizes how online contextual factors breed hostility. Here, we take a different perspective and focus on the offline roots of hostility, that is, offline experiences and stable individual-level dispositions. Using a unique dataset of Danish Twitter users (N = 4,931), we merge data from administrative government registries with a behavioral measure of online hostility. We demonstrate that individua...
• Anomalous wet summers and rising atmospheric CO2 concentrations increase the CO2 sink in a poorly drained forest on permafrost AI翻译

  摘要：At the northern high latitudes, rapid warming, associated changes in the hydrological cycle, and rising atmospheric CO2 concentrations, [CO2], are observed at present. Under rapid environmental changes, it is important to understand the current and future trajectories of the CO2 budget in high- latitude ecosystems. In this study, we present the importance of anomalous wet conditions and rising [CO2] on the long- term CO2 budget based on two decades (2003-2022) of quasicontinuous measurements o...
• Modeling the population-level impact of a third dose of MMR vaccine on a mumps outbreak at the University of Iowa AI翻译

  摘要：Mumps outbreaks among fully vaccinated young adults have raised questions about potential waning of immunity over time and need for a third dose of the measles, mumps, rubella (MMR) vaccine. However, there are currently limited data on real-life effectiveness of the third-dose MMR vaccine in preventing mumps. Here, we used a deterministic compartmental model to infer the effectiveness of the third-dose MMR vaccine in preventing mumps cases by analyzing the mumps outbreak that occurred at the U...
• CD73 promotes non-small cell lung cancer metastasis by regulating Axl signaling independent of GAS6 AI翻译

  摘要：As catabolic enzyme, CD73 dephosphorylates adenosine monophosphate (AMP) and can also regulate tumor cell proliferation and metastasis. To date, very few studies have explored the role of CD73 in mediating non-small cell lung cancer (NSCLC) metastasis, and the underlying transducing signal has not been elucidated. In the pres- ent study, we demonstrated that the CD73/Axl axis could regulate Smad3-- induced epithelial-- to-- mesenchymal transition (EMT) to promote NSCLC metastasis. Mechanically...
• Protection efforts have resulted in ∼ 10% of existing fish biomass on coral reefs AI翻译

  摘要：The amount of ocean protected from fishing and other human impacts has often been used as a metric of conservation progress. However, protection efforts have highly variable outcomes that depend on local conditions, which makes it difficult to quantify what coral reef protection efforts to date have actually achieved at a global scale. Here, we develop a predictive model of how local conditions influence conservation outcomes on similar to 2,600 coral reef sites across 44 ecoregions, which we ...

  摘要：Canopy shade enhances the activity of PHYTOCHROME INTERACTING FACTORs (PIFs) to boost auxin synthesis in the cotyledons. Auxin, together with local PIFs and promotes hypocotyl growth to facilitate access to light. Whether shade alters the cellular redox status thereby affecting growth responses, remains unexplored. Here, we show that, under shade, high auxin levels increased reactive oxygen species and nitric oxide accumulation in the hypocotyl of Arabidopsis. This nitroxidative environment fa...

  摘要：Cyclical population dynamics are a common phenomenon in populations worldwide, yet the spatial organization of these cycles remains poorly understood. In this study, we investigated the spatial form and timing of a population collapse from 2018 to 2022 in Canada lynx ( Lynx canadensis) across the northwest boreal forest. We analyzed survival, reproduction, and dispersal data from 143 individual global positioning system (GPS) collared lynx from populations across five study sites spanning inte...
