Social structural factors outperform economic assumptions in explaining global municipal waste generation
These results show that waste generation reflects a country’s overall social development and institutions, not just its wealth or degree of urbanization, pointing to targeted levers for waste-reduction policy.

China’s changing diets improve human health but increase environmental pressures
China’s dietary transitions improve health outcomes but increase environmental pressures, with faster health gains but rising environmental impacts in urban areas and slower health gains yet higher environmental burdens in rural areas, according to analysis combining environmental and health indicators and scenario modeling

Pliny the Younger advances geochronology
The eruption of Vesuvius volcano witnessed by Pliny the Younger in 79 CE is dated by the argon-40/argon-39 ( 40 Ar/ 39 Ar) method to 1938 ± 13 years (SD) before measurement in 2025 CE.

Model-data synthesis of benthic isotopes suggests a warmer Miocene Climatic Optimum
Our approach yields a maximum likelihood estimate of MCO global mean surface temperature of 7.5∘C above preindustrial, significantly warmer than previous benthic δ18O-based reconstructions, implying a higher MCO-derived estimate of Earth system sensitivity.

A River Wave framework to unify river ecosystem concepts and predict ecological change
Our case study contrasted Sweden’s fragmented rivers with modelled free-flowing conditions and found that the observed fragmented rivers may favour specific fish life history strategies, that ecosystem functioning has shifted towards more baseflow-dominated flow compared with free-flowing rivers and that restoring all rivers to free-flowing conditions would result in more similar rivers nationally.
