`Microbial community analysis reveals enrichment of fermentative and sulphate-reducing taxa, consistent with redox conditions favouring U reduction. By demonstrating the stability of immobilised U(V) alongside U(IV), this work advances the understanding of uranium biogeochemistry and offers new insights for sustainable remediation strategies.`

Arbuscular mycorrhizal (AM) fungal networks are vast underground systems that form symbiotic relationships with the majority of Earth's plant species, exchanging water and nutrients for plant-fixed carbon. A recent global mapping effort revealed these living infrastructures possess a total length of approximately 110 quadrillion kilometers and a mass of roughly 300 megatons of carbon.

Rivers worldwide are progressively warming and losing oxygen, a transformation that turns them into significant, under-accounted sources of greenhouse gases (GHGs). The influx of agricultural and urban nutrients, combined with rising temperatures, fuels microbial activity that releases carbon dioxide, methane, and nitrous oxide into the atmosphere.

We were happy to welcome MSc and BSc students from Wageningen University & Research to the Max Planck Institute for Meteorology in Hamburg yesterday. 🌍

Through presentations on #ClimateModeling, ocean #biogeochemistry, and #cloud observations, the students got an inside look at our research. In small-group discussions with early-career scientists, they could also ask questions about PhDs and careers in #ClimateScience. We finished the visit with a rooftop view over Hamburg 📸

Edward Smith Deevey Jr. (3 December 1914 – 29 November 1988), born in #AlbanyNewYork, was a prominent American #ecologist and #paleolimnologist, and an early protégé of #GEvelynHutchinson at #YaleUniversity. He was a creative pioneer in several areas, including quantitative #palynology, cycling of natural #isotopes, #biogeochemistry, #populationDynamics, #systematics and #ecology of freshwater #zooplankton, and he promoted the use of life tables in ecology. In 1938.
