A collaborative team of researchers from the University of Science and Technology, Beijing, and the Chinese Research Academy of Environmental Sciences has provided an unprecedented molecular-level view into the water quality of urban rivers. The investigation focused on dissolved organic matter (DOM), a complex mixture of carbon-based compounds that influences aquatic ecosystems and drinking water safety. By analyzing the intricate chemical makeup of DOM, scientists can trace its origins, whether from natural soil and plant decay or from human-caused pollution. This new work offers a powerful diagnostic approach for understanding the health of waterways in densely populated areas.

The investigation centered on two vital Beijing waterways with differing roles and surrounding environments: the Yongding River (YDH) and the Beiyun River (BYH). The YDH, known as Beijing's "mother river," primarily serves water supply functions and flows through mountainous, forested terrain. In contrast, the BYH courses through the city’s urban sub-center, receiving significant amounts of domestic sewage and agricultural runoff. This intentional comparison allowed the scientific team to isolate how distinct landscapes and anthropogenic pressures imprint unique chemical signatures on the rivers’ dissolved organic matter pools.

A comprehensive analysis of China's livestock sector shows a significant reduction in greenhouse gas emissions over the last two decades, with projections indicating a further 33.7% decrease by 2030. The investigation, led by researchers Yulong Chen and Le Qi of Inner Mongolia University and Hafiz Athar Hussain of the Chinese Academy of Agricultural Sciences, pinpoints the complex interplay of factors driving this trend, offering a roadmap for sustainable agricultural development. As a major contributor to global agriculture, China's management of non-CO₂ GHG emissions from its livestock industry has profound implications for international climate goals.

Forest soils are immense reservoirs of carbon, playing a critical role in regulating the global climate. The specific sources of this carbon and the processes that stabilize it have been subjects of intense scientific inquiry. A comprehensive investigation by researchers at the Southern University of Science and Technology and Sun Yat-Sen University provides new clarity on the complex dynamics of soil organic matter (SOM). By analyzing soils from 32 natural forests across China, a team led by Guodong Sun and Junjian Wang has uncovered how different components of plant and microbial debris contribute to carbon storage at varying depths, and how these contributions are shaped by climate and geology.

A new study reveals that increasing soil salinity can significantly slow the aging of biochar, a widely used soil amendment, while also suppressing the microbial communities that help drive its environmental benefits. The findings provide important insights into how biochar performs over time in salt-affected agricultural systems.

A new scientific review highlights how biochar, a carbon-rich material produced from biomass, could transform tea farming by restoring soil health, reducing pollution risks, and improving both yield and quality.

Improving soil health is essential for sustainable agriculture and global food security. A new study reports that hydrochar, a carbon-rich material produced from organic waste, may outperform traditional soil amendments such as biochar and crop residues in strengthening soil structure and storing carbon.

Ocean Discovery League (ODL) announces the launch of the Global Deep Sea Exploration Goals, an ambitious international effort to visually explore 10,000 strategically selected locations across the deep seafloor. When completed, this initiative will nearly double the number of unique seafloor locations ever visually observed and produce the first globally representative visual dataset of the deep ocean floor.
