摘要：Quantifying species' niches across a clade reveals how environmental tolerances evolve, and offers insights into present and future distributions. We use herbarium specimens to explore climate niche evolution across 14 annual species of the Streptanthus (s.l.) clade (Brassicaceae), which originated in deserts and diversified into cooler, moister areas. To understand how climate niches evolved, we used historical climate records to estimate each species' 1) classic annual climate niche, average...

摘要：Peptidoglycan (PG), a defining feature of the bacterial cell envelope, is crucial for cell integrity and morphology. PG is a macromolecular mesh consisting of glycan polymers crosslinked by short peptides encasing the cytoplasmic membrane. PG peptides contain two to five amino acids of both L- and D- configuration, with a conserved L- alanine residue at the first position in most bacteria. We previously identified a beta- lactam hypersensitive mutant of Escherichia coli lacking yfiH (renamed p...

摘要：Northeastern US temperate forests are currently net carbon (C) sinks and play an important role offsetting anthropogenic C emissions, but projected climatic changes, including increased temperatures and decreased winter snowpack, may influence this C sink over the next century. Past studies show that growing season warming increases forest C storage through greater soil nutrient availability that contributes to greater rates of net photosynthesis, while reduced winter snowpack induces soil fre...

摘要：The electrocatalytic semihydrogenation of acetylene (C2H2), powered by renewable electricity, provides an energy-and cost-efficient alternative to conventional thermocatalytic methods for purifying crude ethylene (C2H4) streams. This approach provides a more sustainable route to polymer-grade C2H4 by reducing greenhouse gas emissions, yet its commercial potential remains limited by the scarcity of high-performance catalysts and the absence of comprehensive techno-economic analyses for large-sc...

摘要：Stimulus-driven, multiarea processing in the inferotemporal (IT) cortex is thought to be critical for transforming sensory inputs into useful representations of the world. What are the formats of these neural representations and how are they computed across the nodes of the IT networks? A growing literature in computational neuroscience focuses on the computational-level objective of acquiring high-level image statistics that supports useful distinctions, including between object identities or...

摘要：Dengue is the most prevalent arthropod-borne viral disease of humans, with over half the world's population at risk. Infection with any of the four dengue virus (DENY) serotypes is most often self-limiting, but a significant number of cases present with severe dengue characterized by vascular leakage that may be fatal. African ancestry is associated with protection against severe dengue, but the mechanisms are unknown. Using skin explants from genetically defined donors, we show that European ...
