As Some Soils Warm, Microbes Stockpile Essential Nutrients

Javier Barbuzano, Science Writer by Javier Barbuzano 28 January 202628 January 2026

A study in Iceland found that microbes are hoarding more nitrogen for themselves, altering nutrient cycling and leaving less for plants.

Glacier Runoff Becomes Less Nutritious as Glaciers Retreat

Javier Barbuzano, Science Writer by Javier Barbuzano 25 November 202525 November 2025

Sediment from retreating, land-terminating glaciers contains proportionally fewer micronutrients such as iron and manganese, reducing the glaciers’ value to microorganisms at the base of the food web.

Tracing Iron’s Invisible Transformations Just Beneath Our Feet

by Andrew R. C. Grigg, Katrin Schiedung, Joëlle Kubeneck and Ruben Kretzschmar 19 September 202519 September 2025

A new method that adds synthetic iron minerals to soils sheds light on hard-to-observe soil and sediment processes and may have a host of other applications in the Earth sciences and beyond.

Warming Winters Sabotage Trees’ Carbon Uptake

by Grace van Deelen 31 July 202531 July 2025

In temperate forests, the biomass-building benefits of warmer growing seasons are offset by damaging variability in winter weather—a disparity that climate models may miss.
