Waste Polystyrene Chain Scission With Ball Milling: Mass‐Dependent Kinetics and Energy‐Dose Analysis

Journal of Polymer Science, Volume 64, Issue 9, Page 1840-1846, 1 May 2026.
Ball‐milling‐induced chain scission of real‐world polystyrene samples exhibits a systematic dependence on polymer mass when particle size is controlled. Scission rate constants follow power‐law scaling, and molecular weight evolution data collapse when analyzed by mechanical energy dose.

Phytoplankton and Temperature Control Seasonal Dynamics of Greenhouse Gases in a Large River

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Rivers are a dynamic source of greenhouse gases (GHGs), yet the temporal variability and controlling mechanisms of their CO2:CH4:N2O ratios remain poorly constrained. We monitored the three GHGs in the German river Elbe over 5 years at two sites to identify seasonal controls as well as travel time related and site‐specific mechanisms driving ...

Highly Variable Methane Production and Fluxes in a Hypereutrophic Lake Despite Uniform Bathymetry and Sediment Chemistry

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Hypereutrophic lakes support high sedimentation of labile organic carbon, promoting sediment anoxia and GHG potential production. Lakes with complex morphometry exhibit extensive spatial heterogeneity in sediment methane (CH4) and carbon dioxide CO2 dynamics. We wondered: do lakes with uniform bathymetry show low spatial variation in sediments'

In‐Lake GHG Production Constrained by Lake DOM Mass Balance in a Boreal Catchment

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract The processing of organic carbon in surface waters represents a critical component of the carbon (C) cycle in boreal landscapes and is closely linked to greenhouse gas (GHG) emissions, primarily carbon dioxide (CO2) and methane (CH4). Utilizing a unique data set with dense monitoring of dissolved organic carbon (DOC), dissolved CO2, and CH4 at

From Rainfall to Rumors: Interpreting the 2024 Bangladesh Floods Through Numbers, Narratives, and Information Gaps

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract When severe floods struck southeastern Bangladesh in August 2024, competing explanations emerged. Meteorological analysis revealed that extreme precipitation was exacerbated by the Madden‐Julian Oscillation and jet stream dynamics. However, alternative narratives proliferated on social media, particularly claims that India deliberately ...
