Satellite observations, plume dynamics, and volcanic lightning from the 2023 eruption of Shishaldin Volcano, AlaskaNARA Subscribed
The 2023 eruption of Shishaldin Volcano, Alaska, provided an unusually well-monitored example of a “dry” (non-hydromagmatic) explosive basaltic eruption with sustained, buoyant plumes, and pyroclastic density currents. Here, we examine the 13 basaltic paroxysms that occurred between July and November 2023 using geostationary satellite observations, plume modeling, and volcanic lightning detection to characterize mass eruption...
Authigenic grey monazite from Ordovician metasediments of the Iberian massif: the Matamulas placerNARA Subscribed
Authigenic nodular monazite occurs in dark, Middle Ordovician, low-grade metapelites of the Central Iberian and West Asturian-Leonese Zones of the Iberian Massif. Erosion of monazite-bearing slates and phyllites, and short-range transport resulted in localised recent alluvial deposits rich in millimetre-size monazite, of which the Matamulas site, within the Central Iberian Zone, represents one of the most extensive and potenti...
Global patterns and regional insights into kelp forest protection, restoration, and stewardshipNARA Subscribed
Kelp forests are among the most extensive and productive coastal ecosystems, yet they remain underrepresented in global conservation policy despite widespread declines driven by interacting global- (i.e., ocean warming, marine heatwaves) to local-scale stressors. At the same time, kelp conservation and restoration efforts are expanding rapidly across regions, but measures of success and syntheses tend to primarily focus on eco...
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...
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...
Assessing the health impact of the national air pollution control programme at city level: the case of MadridNARA Subscribed
This paper aims to provide scientific support for decision-making regarding improvements in air quality by evaluating pollution reduction measures included in the 1st Spanish National Air Pollution Control Programme (SAPCP) at the city level. The study assesses the health impacts of the main air pollutants—particulate matter (PM), nitrogen dioxide (NO 2 ), and ozone (O 3 )—on the population of Madrid. Two scenarios are analyse...
This study introduces the first high-resolution hazard probability maps of extreme precipitation for Spain, marking a significant step toward a national climate service for hydrometeorological extremes. Using long-term daily precipitation records from a dense network of stations and incorporating topographic data, the methodology combines the Generalized Pareto distribution with universal kriging to spatially interpolate distr...
