Recognizing the Curiosity-Driven Discoveries by 2024 Nobel Prize Winners Ambros, Ruvkun, and Baker

Earlier this month, we were honored to add three names to the list of Nobel laureates whose work has been supported by NIH. The 2024 Nobel Prize in Physiology or Medicine was jointly awarded to Victor Ambros and Gary Ruvkun for their discovery of microRNA and its role in post-transcriptional gene regulation. In addition, David Baker, one of three awardees of the Nobel Prize in Chemistry for his work in designing new computational proteins, is a long-time recipient of NIH support. On behalf of the NIH community, I’d like to congratulate these esteemed researchers for receiving this honor and thank them for their pioneering contributions to biomedical science.
