Contamination characteristics, source analysis and health risk assessment of heavy metals in the soil in Shi River Basin in China based on high density sampling

Ecotoxicology and Environmental Safety, 2021
To explore the contamination of heavy metals in the Shi River Basin soil in China, a high density sampling of surface soil was conducted. In this study, an absolute principal component scores multiple linear regression model (APCS-MLR) was used to ...

Abandonment Leads to Changes in Forest Structural and Soil Organic Carbon Stocks in Moso Bamboo Forests

Plants
The important role of soil carbon pools in coping with climate change has become widely recognized. Moso bamboo (Phyllostachys pubescens) is an economically important bamboo species in South China; however, owing to factors such as rising labor costs and

Disentangling the Roles of Microbial Traits and Mineral Protection in Regulating Temperature Sensitivity of Soil Carbon Decomposition in Eroded and Depositional Agricultural Soils

Earth's Future
The temperature sensitivity of soil organic carbon decomposition (Q10) governs the fate of soil carbon under global warming. Although erosion redistributes soil carbon at scales comparable to the terrestrial carbon sink, how erosion reshapes Q10 across ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

An experimental study of the reinforcement mechanism and erosion resistance of nano silicon-based sand-fixation material

Shuiwen dizhi gongcheng dizhi, 2023
To reduce the slope collapse and soil erosion under the action of rainfall erosion in desertification areas, the self-developed nano silicon-based sand-fixation material (Nano-Silicon/Polymer Composites，NSPC) is proposed to protect the sandy slope ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.
