One of three scientists just awarded the 2025 Nobel Prize in Medicine has no idea that he just won because, according to friends, he's living his best life hiking off the grid somewhere in Idaho. The Nobel committee has so far failed to contact Fred Ramsdell, whose work on the immune system helped revolutionize treatments for autoimmune diseases. His colleague and friend Jeffrey Bluestone, co-founder of Sonoma Biotherapeutics in San Francisco, confirmed he's also been unable to reach him.
