Levels of Essential and Nonessential Metals in Flower Farm and Roadside Soils of Holeta, Ethiopia, Determined by Flame Atomic Absorption Spectrophotometry

Applied and Environmental Soil Science
Heavy metals, a group of trace elements naturally present in the Earth’s crust in forms, such as oxides, carbonates, and sulfides, are known for their potential long-term adverse effects on human health and the environment.

Environmental, ecological and human health risk assessment for Ba, Cr, Zn and V in minesoil after 20 years of restoration in southern Brazil

Frontiers in Soil Science
Heavy metals are a persistent threat in soils formed after mining (minesoils). This study was conducted in a 20-year randomized complete block design experiment installed within an active coal mine in Candiota, southern Brazil. Thus, this work provides a

Rainfall Shapes the Diversity of Soil Nitrogen‐Fixing Microorganisms Worldwide

Advanced Science, EarlyView.
This study reveals the distinctive pattern and mechanism of rainfall driving the global biodiversity and biogeography of soil potential N‐fixing microorganisms, and constructs the theoretical framework. The results guide us on how to maintain ecosystem productivity under future climate changes (e.g., whether a specific region needs more N fertilizers ...

CDK4/MERCs/PINK1 Axis Drives PFOA/HFPO‐TA‐Induced Cardiac Senescence via Mitophagy Defect and cGAS‐STING Activation: In Vitro Amelioration by Cycloastragenol

Advanced Science, EarlyView.
The present study demonstrated that PFOA and HFPO‐TA exposure suppressed CDK4, disrupted MERCs and impaired PINK1/Parkin‐mediated mitophagy, thereby accelerating cardiac senescence, whereas CAG effectively reversed these pathological changes in vitro. Our findings identify CDK4 as a critical regulator bridging mitophagy defects and cardiac senescence ...

Constrained Forest Methane Sink by Thermal Adaptation of Soil Methanotrophs

Advanced Science, EarlyView.
Climate warming can stimulate methanotroph‐mediated CH4 oxidation in forest soils, thereby mitigating the increase in atmospheric CH4 concentrations. By integrating evidence from a macro‐climatic thermal gradient and a 70‐day incubation experiment, this study demonstrates that microbial methanotrophs can adapt to long‐term temperature changes at the ...
