Diversity and extracellular enzymatic activity of culturable yeasts isolated from soil in a Brazilian Amazonian rainforest biomeNARA Subscribed
The Amazon rainforest represents the largest and most biodiverse tropical rainforest in the world, comprising over half of the planet’s remaining rainforests. In this study, we investigated the yeast distribution in the soils in a Brazilian Amazonian rainforest biome. The collection sites included two upland forests, a black-water floodplain forest, and an Amazonian dark earth site. Yeasts were isolated using both enrichment a...
Quantifying Pathogen eDNA at a Trap‐and‐Haul Facility for Adult Chinook Salmon ( Oncorhynchus tshawytscha )NARA Subscribed
Adult Chinook salmon ( Oncorhynchus tshawytscha ) trap‐and‐haul operations exist in rivers across the Pacific Northwest with the objective of re‐establishing salmon populations above impoundments. These efforts are complicated by high prespawn mortality (PSM), which can hinder restoration by reducing reproductive success. Recent improvements at trapping facilities in the Willamette River Basin, Oregon, USA, may reduce PSM by s...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Regulation of chemicals demands assessment of risks rather than identification of hazards onlyNARA Subscribed
This position paper was collaboratively written during the international expert symposium “EU Chemicals Assessment - Risk- or Hazard-based?” that was organised by the German Federal Institute for Risk Assessment (BfR) in Berlin on November 27th and 28th 2025. Twenty experts from several institutions and European countries considered the scientific merits of both hazard-based and risk-based approaches to chemical safety assessm...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
Oxygen is fundamental to ocean biogeochemical processes, with deoxygenation potentially reducing biodiversity, and disrupting biogeochemical cycles. In recent decades, the global ocean oxygen concentration has been decreasing, but this decrease is underestimated in numerical ocean models by as much as 50 %. Mechanisms responsible for this deoxygenation include (i) solubility-driven deoxygenation due to ocean warming, and (ii)...
Open-Coast Eelgrass (Zostera marina) Transplant Catalyzes Rapid Mirroring of Structure and Function of Extant EelgrassesNARA Subscribed
Seagrasses are marine angiosperms that function as ecosystem engineers, forming complex structure that enhance nearshore environments. Globally, seagrass habitats are threatened by intensifying impacts from climate change, which exacerbate non-climatic stressors such as coastal development, invasive species, and overfishing. Advances in the methodological efficacy of active seagrass restoration efforts have sought to mitigate...
Mucosal vaccination generates protective immune responses directly at the primary site of STI infection. However, the delivery of nanoparticles is hindered by the mucus barrier at these mucosal surfaces. Due to this interference, research on mucosal administration of self-amplifying (sa)-mRNA encapsulated in lipid nanoparticles (LNP) is currently limited and inconsistent. Some progress has been reported for nasal mRNA vaccinat...
Functions and clinical implications of the liver microenvironment in hepatic uveal melanoma metastasesNARA Subscribed
Uveal melanoma (UM) is an aggressive intraocular malignancy in adults arising from the melanocytes of the uveal tract. While primary UM lesions can be successfully treated, ~ 50% of UM patients develop metastases primarily in the liver. Patients with liver metastatic UM (LMUM) have poor prognosis and few therapeutic options. LMUM lesions are unresponsive to standard chemotherapies, targeted therapies, and immune checkpoint inh...
Pure mycelium materials (PMMs) are a sustainable alternative for a range of non-sustainable products such as textile, leather and meat. So far, properties of PMMs of different fungi have not been systematically assessed. Here, 11 mushroom-forming fungi, of which 10 isolated from nature, were grown in liquid shaken cultures. Schizophyllum commune, Ganoderma resinaceum , and Trametes betulina produced the highest biomass (8.62,...
The Local Turn in a Global Sea: Identifying Sustainability Trade‐Offs in Regionalized Marine Aquaculture SystemsNARA Subscribed
Marine aquaculture, like the broader seafood industry, relies heavily on international trade and global supply chains for both production and sales. Recent global disruptions, including the COVID‐19 pandemic, the Russian invasion of Ukraine, the conflicts in the Middle East, and trade tensions, have exposed the social and economic vulnerabilities inherent in a globalized production system. In response, these events have sparke...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Siberian boreal forests have experienced increases in fire extent and intensity in recent years, which may threaten their role as carbon (C) sinks. Larch forests ( Larix spp.) cover approximately 2.6 million km 2 across Siberia, yet little is known about the magnitude and drivers of carbon combustion in these ecosystems. To address the paucity of field‐based estimates of fuel load and consumption in Siberian larch forests, we...
