A bold yet increasingly urgent prediction is emerging: future farmlands may gradually shift from “purely natural systems” to “semi-engineered systems,” where key climate variables are precisely regulated while preserving natural light and soil ecosystem functions. www.maxapress.com/article/doi/...
Manipulating natural heatwaves in AmbControl chambers: bridging controlled and field conditions for warming studies in plant–soil systems
<p>Quantifying the impact of natural heatwaves on crop productivity requires direct comparison with a no-heatwave control. Yet conventional growth chambers, which rely on artificial lighting and stepw...

Microbial iron mining: a nature-based solution for pollution removal and resource recovery from contaminated soils
<p>Thousands of natural and synthetic compounds pollute soils and threaten ecosystems and human health. In 2021, the Food and Agriculture Organization and the United Nations Environment Programme (FAO...

Water first: why effective water management outweighs genetic drought tolerance in agricultural adaptation
<p>Climate change intensifies droughts globally, threatening crop yields and food security. Although breeding drought-tolerant crops is widely promoted as an adaptation strategy, their effectiveness i...

🧵 Thallium (Tl) is most mobile during redox fluctuations—not in fully oxic or anoxic conditions.
Cycling environments (wetlands, soils) release Tl as Tl⁺, which mimics K⁺ and enters food chains.
Stable ≠ safe. Dynamic = danger. www.sciencedirect.com/science/arti...
Hotspots and dynamics of dissolved thallium species at oxic-anoxic interfaces in flooded soils
Thallium (Tl) is highly toxic, predominantly existing in its monovalent Tl(I) state in the environment. However, the redox “niche” of both dissolved t…

Google AI model mines trillions of images to create maps of Earth ‘at any place and time’
Nature - The system will save time spent on processing satellite data, researchers say — but they hope the tech firm will share more about how it works.
