Fine‐Tuning a Weather Foundation Model With Lightweight Decoders for Unseen Physical Processes

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Recent advances in AI weather forecasting have led to the emergence of so‐called “foundation models”, typically defined by expensive pretraining and minimal fine‐tuning for downstream tasks. However, in the natural sciences, a desirable foundation model should also encode meaningful statistical relationships between the underlying physical ...

Long‐term reduction of invasive killer shrimp (Dikerogammarus villosus) density following removal of zebra mussel (Dreissena polymorpha) shells and coarse substrate on UK lake beds

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Working with Citizen Scientists, researchers tested manual removal of coarse cobbles and zebra mussel shells from fine‐sediment lake beds to reduce invasive killer shrimp densities. Killer shrimp use these features for habitat, and after clearing them from 3 × 3 m sections of lakebed, killer shrimp densities were reduced by over 90% in these sections ...
