摘要:We explore how and when Hells Canyon, North America's deepest river gorge (similar to 2,400 m deep), formed, addressing these fundamental questions first posed by W. Lindgren [The Gold Belt of the Blue Mountains of Oregon (1901)]. Existing hypotheses about the canyon's formation and timing of incision remain speculative due to a lack of direct constraints and geomorphic analysis in the canyon. Herein, we combine cosmogenic nuclide dating of cave-bound river deposits, river profile analysis, an...

摘要:Institutional legitimacy is essential for democracies, yet public trust and confidence in the United States Congress are at an all-time low. A significant predictor of attitudes toward Congress is perceptions of corruption, with perceptions of corruption in government linked to less legitimacy. This study tests whether knowledge of Congressional stock trading affects legitimacy and compliance with Congressional authority. In a preregistered experiment with US citizens (n = 506), participants w...

摘要:Vinculin forms a catch bond with the cytoskeletal polymer actin, displaying an increased bond lifetime upon force application. Notably, this behavior depends on the direction of the applied force, which has significant implications for cellular mechanotransduction. In this work, we present a comprehensive molecular dynamics simulation study, employing enhanced sampling techniques to investigate the thermodynamic, kinetic, and mechanistic aspects of this phenomenon at physiologically relevant f...

摘要:A major focus of human genetics is to map severe disease mutations. Increasingly, that goal is understood as requiring huge numbers of people to be sequenced from every broadly defined genetic ancestry group, so as not to miss ancestry- specific variants. Here, we consider whether this focus is warranted. We start from first principles considerations, based on models of mutation-drift- selection balance, which suggest that since severe disease mutations tend to be strongly deleterious, and thu...

摘要:We employ fine-scale population genetic analyses to reveal dynamics among interacting forces that act at synonymous sites and introns among closely related Drosophila cies. Synonymous codon usage bias has proven to be well suited for population genetic inference. Under major codon preference (MCP), translationally superior major codons confer fitness benefits relative to their less efficiently and/or accurately decoded synonymous counterparts. Our codon family and lineage-specific analyses exp...

摘要:Alzheimer's disease (AD) and traumatic brain injury (TBI) are currently untreatable neurodegenerative disorders afflicting millions of people worldwide. These conditions are pathologically related, and TBI is one of the greatest risk factors for AD. Although blood-brain barrier (BBB) disruption drives progression of both AD and TBI, strategies to preserve BBB integrity have been hindered by lack of actionable targets. Here, we identify 15-hydroxyprostaglandin dehydrogenase (15-PGDH), an enzyme...

摘要:Overexploitation has depleted fish stocks during the past century; nonetheless, its genomic consequences remain poorly understood for most species. Characterizing the spatiotemporal patterns of these consequences may provide baseline estimates of past diversity and productivity to aid management targets, help predict future dynamics, and facilitate the identification of evolutionary factors limiting fish population recovery. Here, we evaluate human impacts on the evolution of the iconic Atlant...

摘要:The minimum separation between reconnecting vortices in fluids and superfluids obeys a universal scaling law with respect to time. The prereconnection and the postreconnection prefactors of this scaling law are different, a property related to irreversibility and to energy transfer and dissipation mechanisms. In the present work, we determine the temperature dependence of these prefactors in superfluid helium from experiments and a numeric model which fully accounts for the coupled dynamics of...

摘要:Many neurodegenerative disorders (NDDs) preferentially affect neurons with long or complex axonal arbors but the cellular and molecular bases for neurite length-dependent vulnerability of neurons to degeneration is largely unknown. Using Drosophila sensory neurons as a model system we show that neuronal activation of the integrated stress response triggers expression of the Interleukin-6 homolog unpaired3 (upd3), which is both necessary and sufficient for axon length-dependent degeneration of ...

摘要:The incident ultraviolet (UV) irradiance on the surface of Mars is strongly sterilizing and plays a critical role in atmospheric and near- surface photochemistry. The Rover Environmental Monitoring Station (REMS) instrument, which includes the first UV sensor sent to Mars on board the Curiosity rover, has been measuring the UV irradiance at Gale Crater since 2012, providing ground- truth data regarding seasonal and short- term variability of the UV radiation at the surface of another planet.
