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

Global Carbon Investment in Terrestrial Biological Nitrogen Fixation
Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.Abstract Biological nitrogen (N) fixation (BNF) provides the N needed to produce proteins and other biological building blocks, helping feed humanity and mitigate climate change. Due to its high energetic cost compared to other forms of N acquisition, biotic investment in BNF indicates N limitation. Globally gridded BNF flux data provide an opportunity

Austral Entomology, Volume 65, Issue 3, August 2026.ABSTRACT A new species of jewel beetle, Temognatha sundholmi Lang, sp. nov., is described from the Great Victoria Desert in South Australia. A broader investigation, using mtDNA COI ‘barcode’ sequences from 178 specimens representing 54 buprestid species, places the new species with Temognatha flavocincta (Gory & Laporte, 1838) in the informal ...

Competition and payments to African chiefs on the Gold Coast during the slave trade, 1679‒1704
The Economic History Review, Volume 79, Issue 3, Page 1052-1081, August 2026.Abstract The manuscript records of the Royal African Company show that the Company paid African chiefs for access to trade along the caravan routes on the Gold Coast in the seventeenth century. This paper documents and examines these payments. Using an event study, I establish that after the Glorious Revolution in 1688 when the Company's monopoly in ...
