This research investigates whether replacing meat with fish could improve nutrition while supporting more sustainable diets. Modelling UK and Irish dietary data found that replacing even 25% of meat increased intake of key nutrients, including vitamin D, omega-3, selenium, and iodine, suggesting simple dietary swaps could benefit health and sustainability.

This research links two major treatment challenges in childhood acute lymphoblastic leukemia through ferroptosis, a lipid oxidation process regulated by selenium. By targeting selenium uptake in the brain and after chemotherapy, the work identifies potential new therapeutic strategies to reduce cancer cell survival and improve long-term treatment outcomes.
