The majority of young children showed good vitamin D status, no child had indications of deficiency, but among some intake was too low. This is the result of a study encompassing over 1,800 infants in Sweden. Foods providing children with vitamin D also contributed to greenhouse gas emissions.

Based on a 20-year field nitrogen addition experiment, this study demonstrates that long-term high nitrogen deposition does not reduce belowground carbon allocation in tropical forest plants; rather, it induces a physiological adaptation—upregulation of root exudation—to actively mobilize soil phosphorus, thereby sustaining productivity and offering a key mechanistic explanation for the persistence of tropical forest carbon sinks under chronic nitrogen enrichment.

EU-funded researchers have completed the most comprehensive assessment ever of Europe's "urban mine" — the critical raw materials embedded in waste streams including electronics, batteries, vehicles, wind turbines, and demolition debris. The  FutuRaM (Future Availability of Secondary Raw Materials) project mapped 42 critical elements across seven waste categories in 31 countries, finding that annual recovery could reach 4.1–5.7 million tonnes by 2050, potentially substituting up to 56% of primary material imports. Recovery of key metals like lithium, cobalt, and nickel could grow dramatically, reducing dependence on China and other suppliers. The project's Urban Mine Platform makes all data publicly accessible to guide investment and policy decisions.

Every summer for nearly three decades, a team at Michigan State University has made their way to Manistee National Forest to look for new trees that have sprouted. At less than a year old, the youngest seedlings aren’t much taller than their toes. But now, the team’s annual counts of 10 tree species are starting to reveal clues to what the region’s forests might look like in the 20, 40 or 100 years to come.

New research from Queen Mary University of London shows how extreme seasonal patterns are causing rainforest butterflies to adapt their reproductive strategies at a rapid pace, with implications for species resilience under accelerating climate disruption. 

Most people think of ice as frozen and lifeless, but research at Umeå University shows the opposite. A new study published in PNAS demonstrates that ice actively speeds up the breakdown of iron minerals and may release more iron than current environmental models account for. This is crucial for predicting how nutrient cycles, carbon storage, and water quality will change in polar and mountain regions as the planet warms.
