Farmed Escapees Threaten MHC Diversity in Wild Atlantic Salmon

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Wild Atlantic salmon populations in Norway and elsewhere are experiencing long‐term declines driven by reduced marine survival, climate change, impacts from aquaculture, introduction of alien species, and environmental degradation. Understanding how immune diversity is affected by these declines, and thus the ability of Atlantic salmon to ...

Advancing Photonic Inverse Design with Interpretable Machine Learning

Advanced Photonics Research, Volume 7, Issue 5, May 2026.
The work applies the interpretable machine learning technique called LIME (local interpretable model‐agnostic explanations) to the inverse design of photonic chips, revealing hidden optimization patterns and guiding better starting designs. Using insights from LIME improves performance of two‐mode multiplexers, showing interpretable methods can ...
