Precision greenness exposure is associated with lung cancer risk in medicare beneficiariesNARA Subscribed
Purpose This study examines whether lung cancer risk is influenced by block-level greenness, controlling for age, sex, race/ethnicity, area deprivation index (ADI), and walkability in older adults, and whether age, sex, race/ethnicity, ADI, or walkability plays a moderating role in this relationship. Methods Data from US Medicare beneficiaries aged 65 years and older were included for the years 2011 and 2016. Beneficiaries inc...
Multi‐Model Ensembles in Ecosystem Modeling: Challenges and Best Practices for Decision‐MakingNARA Subscribed
Ecosystem models are increasingly central to the decision‐making for environmental policy, conservation planning, and climate‐related investments. Yet, the growing reliance on Multi‐Model Ensembles (MMEs) of ecosystem models by practitioners and policymakers, sometimes under tight timelines and imperfect information, has frequently outpaced the scientific rigor required to ensure ensemble reliability. Here, MMEs refer to appro...
Synergistic Interactions Between Warming and Elevated Atmospheric CO 2 Increase Soil Organic Carbon SequestrationNARA Subscribed
Warming and elevated CO 2 (eCO 2 ) are two potentially opposing climate‐carbon (C) feedback mechanisms that modulate the magnitude of the land C sink, with warming decreasing and eCO 2 increasing C sequestration. However, their net effect on soil organic C (SOC)—the largest terrestrial C stock—remains uncertain. Here, we quantify how warming, eCO 2 , and their interactions influence SOC by using 5558 paired observations from 1...

Theta-aurora dynamics: Ionospheric mapping of evolving magnetospheric plasma boundariesNARA Subscribed
The theta-aurora, an auroral feature bridging the nightside and dayside auroral oval under a northward interplanetary magnetic field (IMF), is closely linked to the energetic plasma evolving within the magnetosphere. While existing views emphasize that energetic plasma resides on closed field lines, the mechanism by which it is accelerated and precipitates on open field lines to form the theta aurora remains poorly understood....
Discovery of a Potent Small Molecule Antagonist of GRPR for the Treatment of PruritusNARA Subscribed
Persistent pruritus (itch) affects the quality of life, and many itch syndromes remain untreatable. Previously, we identified the gastrin-releasing peptide receptor (GRPR) playing a critical role in mediating histamine-independent itch signaling. In this study, we aimed to identify small-molecule GRPR antagonists to treat histamine-independent itch. Starting with the known small-molecule GRPR antagonist PD 176,252, we conducte...
Multimorbidity as a predictor of mortality in companion dogsNARA Subscribed
Soil organic carbon (SOC) sequestration is vital for food security and climate mitigation. However, its long‐term response to fertilisation remains unclear. Using the 180‐year Broadbalk Experiment (the world's longest‐running fertilisation trial; Rothamsted, UK), combined with 14 C labelling and metagenomics, we identified fundamentally distinct mechanisms of SOC accumulation: a microbially mediated dual pathway under organic...
Age-related skeletal muscle deterioration is a commonly reported disability among older adults, attributed to several factors including mitochondrial dysfunction, a major hallmark of aging. Therapies to attenuate or reverse mitochondrial decline are limited. Despite identified positive relationships between vitamin B12 (B12) and mitochondrial biology, the impact of B12 supplementation on skeletal muscle mitochondria, in advanc...
