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...
Full Manure Recycling Risks an 18% Rise in China's Cropland N 2 O Emissions Without Improved ManagementNARA Subscribed
Cropland fertilization is the largest anthropogenic source of nitrous oxide (N 2 O‐N) emissions in China and could be mitigated through manure substitution. However, accurate quantification of N 2 O‐N losses under different combinations of manure and chemical fertilizer applications remains challenging due to limited national data, oversimplified methods of estimation, and neglect of the nitrogen (N) source (chemical‐N and man...
As a promising strategy for improving soil health and mitigating climate change, biochar has received increasing attention in recent years. However, findings regarding its microbial effects are often context-dependent, and the complex impacts of biochar on soil microbial communities remain inadequately understood. Here, we integrated 843 samples of 16 S rRNA sequencing data from 24 independent studies, utilizing machine learni...
Soil organic carbon (C) is derived primarily from plant and microbial necromass; however, the global distribution and contribution of different necromass inputs to soil C storage remain unclear. We conducted a global meta‐analysis encompassing 2410 observations from 249 microbial necromass studies and 786 observations from 72 plant residue studies. The results showed that the content of microbial‐derived C (10.63 ± 0.39 g C kg...
