The sand used to build cities, roads and other infrastructure is being removed from many rivers faster than nature can replace it, according to a global review led by researchers from Nanyang Technological University, Singapore (NTU Singapore).

Researchers at University of Tsukuba have discovered that rainwater runoff in the highly rugged sedimentary rock mountains of Japan's Southern Alps is governed by two processes: "deep infiltration" and "shallow drainage via landslides." These processes are dictated by the inclination of geological strata. Based on these findings, the researchers propose a conceptual framework, termed the "structural ground system," to explain how the bedding structure regulates rainwater runoff.

Built on the open-access publishing platform of NEW HORIZON PRESS LIMITED, NEW Community engaged in international outreach and scholarly exchange during the 2026 international geochemistry conference. Its activities centered on emerging topics including AI-ready geochemical data, carbon removal, enhanced rock weathering, biogeochemical cycles, contaminant transport and transformation, and climate change, with the aim of fostering interdisciplinary research networks.

New analysis shows that a ‘pause’ in Arctic winter sea ice decline seen in the early 2020s has ended following record lows in 2025 and early 2026.

Webcams commonly used by surfers are helping scientists measure Oregon's coastal fog, shows a study from UC Davis and the USDA Forest Service. 

Researchers analyzed snow droughts in Xinjiang from 1980 to 2021 and classified them into warm-only, dry-only, and warm-dry types. The study identifies strong spatial heterogeneity, highlights the Kunlun Mountains as a major hotspot, and shows that warm-dry snow droughts increased markedly after 2000.
