Site Selection for Seaweed Biofilters Installation within the Great Barrier Reef World Heritage AreaNARA Subscribed
Elevated terrestrial nutrient loads entering coastal waters in northeastern Australia are adversely affecting the Great Barrier Reef World Heritage Area. ‘Seaweed biofilters’ have been proposed as a mechanism for the bioextraction of elevated nutrient levels from coastal environments, with potential to target diffuse source nutrient discharges while generating biomass with potential applications as fertiliser, soil conditionin...
Intermittent, Double Estuarine Turbidity Maximum in a Mesotidal Estuary with Low Freshwater InputNARA Subscribed
The Estuarine Turbidity Maximum (ETM) is a biogeochemical hotspot in estuaries that regulates ecosystem health by amplifying estuarine water filtering. Convergence of elevated turbidity in an ETM is due to the intersection of repeated sediment resuspension and physical characteristics of a system. ETM formation depends on various tidal and freshwater conditions, making its ecological impact difficult to predict. Understanding...
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...
Integrated Reanalysis of Global Riverine Fish eDNA Datasets Shows Robustness and Congruence of Biodiversity ConclusionsNARA Subscribed
The analysis of environmental DNA (eDNA) has revolutionized biodiversity assessments in aquatic ecosystems, enabling non‐invasive monitoring of fish communities across diverse regions. However, the global comparability of these eDNA datasets remains ambiguous due to heterogeneous sampling protocols and bioinformatic workflows across studies, making it difficult to assess how robust and comparable the biodiversity patterns infe...
The role of living shorelines as a resilience strategy for nutrient reduction in estuarine systemsOA Marine
Introduction Tidal salt marshes provide critical ecosystem services in estuaries including the removal, storage, and transformation of nutrients, improving water quality and aquatic habitat. As tidal marshes drown from sea level rise, this service is lost, impacting estuarine resilience and leading to degradation of water quality. Living shorelines are a strategy to protect shorelines, while restoring some capacity to improve...
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...

Per- and Polyfluoroalkyl Substances (PFAS) Enhance Cholesterol Accumulation and Dysregulate Inflammatory Responses in MacrophagesNARA Subscribed
Epidemiological studies and in vivo animal models have shown that exposure to PFAS can lead to cardiovascular toxicity and promote atherosclerosis. In this study, we explored the effects of PFOA and PFOS exposure on lipid accumulation in macrophages and analyzed critical markers of foam cell formation, which are early precursors of atherosclerotic lesions. Our results demonstrate that PFOS and PFOA enhance lipid and cholestero...
Less is more; intermediate oiling has a greater impact than heavy oiling on feather permeability in Northern Gannets (Morus bassanus)NARA Subscribed
Northern gannets are the largest migratory seabird in the Northern Atlantic and are vulnerable to oil pollution as a result of industrialisation spreading to marine environments. This study experimentally investigated the effect of crude oil on gannet feathers under laboratory conditions, with respect to (a) mass accumulation from contact with oil on water surface, and (b) water permeability of feathers following oiling. Ganne...
