A new laboratory study combines large-amplitude oscillatory shear (LAOS) and Fourier-transform rheology to track how loess slurry responds as deformation increases. Tests across three water contents and frequencies of 0.1–10 Hz identify four strain markers that distinguish the linear regime, nonlinear yielding and the solid–liquid crossover. Water content and loading frequency jointly shape these thresholds. Under the tested conditions, the slurry with 36% water content remained solid-like at 5–10 Hz. The findings provide a strain-resolved framework for studying mudflow behavior, while field-scale thresholds still require validation.

A new species of dinosaur - a long-clawed predator the size of a large tiger - has been discovered by a University College London (UCL) led team from a fossil found on the Isle of Wight.

Peatlands in the Alps are mostly small, scattered and difficult to access. As a result, up-to-date information on their extent and condition is often lacking. An international research team, including researchers from the University of Göttingen, has now developed a cross-border approach to identifying these particular areas. A comparison with official maps shows that the model identifies many peatlands as smaller than previously mapped – particularly in areas where aerial photographs reveal visible signs of disturbance. The findings were published in the journal Communications Earth & Environment.

Using satellite technology, Virginia Tech geoscientists estimated groundwater depletion across the Colorado River Basin, finding recent losses greater in the historically resilient Upper Basin.

Reaching net zero sooner would limit long-lasting changes to El Niño and the tropical Pacific, new climate modelling suggests, although heat stored deep in the ocean means changes to the tropical Pacific could persist for centuries. 

A new study examining how tropical cyclone activity near Hawai‘i could change in a warmer future finds a shift toward stronger storms, even though substantial uncertainty remains about whether the total number of storms near the islands will increase.

The University of Oklahoma will receive up to $220 million over five years from the U.S. Department of Commerce and the National Oceanic and Atmospheric Administration (NOAA) to continue the life-saving weather research led by the OU-NOAA Cooperative Institute for Severe and High-Impact Weather Research and Operations (CIWRO).
