Aggregate stability in soils cultivated with eucalyptus. [PDF]

, 2019
The objective of this work was to evaluate the aggregate stability of tropical soils under eucalyptus plantation and native vegetation, and assess the relationships between aggregate stability and some soil chemical and physical properties.

Fractal and compositional analysis of soil aggregation

, 2011
A soil aggregate is made of closely packed sand, silt, clay, and organic particles building up soil structure. Soil aggregation is a soil quality index integrating the chemical, physical, and biological processes involved in the genesis of soil structure and tilth.

Root‐Stimulated Movements in Mimosa Pudica for Biohybrid Robotic Systems

Advanced Robotics Research, EarlyView.
This study demonstrates that thermal and electrical stimulation of Mimosa pudica root induces movement of the petiole and pinnules without direct stimulation of the aerial organs, thereby enabling a plant‐based robotic gripper and providing a foundation for the development of intelligent and sustainable systems.

Divergent responses of aggregate breakdown by slaking to nitrogen forms in solution for contrasting soil types

Geoderma
Aggregate stability strongly affects many soil processes and is critical to maintain sustainable agriculture. Aggregate breakdown is controlled by the interaction between soil intrinsic properties and solution characteristics.

Mechanisms of carbon and nutrient release from acid impacted soils: Investigating competitive sorption and aggregate dispersion [PDF]

, 2018
Dissolved organic carbon (DOC) and associated nutrients are of critical importance to natural biogeochemical cycling. In recent decades, increased amounts of DOC have been observed in Northern Hemisphere surface waters recovering from acid deposition ...

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Responses of soil aggregate characteristics to grazing intensity differ between topsoil and subsoil in a typical steppe

Frontiers in Environmental Science
Soil aggregates are vital to soil structure, influencing grassland ecosystem health and sustainability. As a dominant land use in grasslands, grazing acts as a key driver of ecosystem structure and function, yet the responses of aggregate size ...

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

Advanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,

Paving the Way to Elucidate Hg's Role in Tumorigenesis

Advanced Science, EarlyView.
Tumorigenesis can result from diverse environmental carcinogens. Among them, mercury—a lifelong bioaccumulative Group 2B carcinogen—has tumorigenic potential that remains poorly understood due to confounding co‐exposures and limited organ‐specific data.

Using factor analysis to distinguish between effective and ineffective aggregate stability indices [PDF]

, 2012
Several existing aggregate stability indices are commonly used to represent aggregate stability of soil. Consequently, there is a need to determine how well these common indices characterize or represent aggregate stability.
