Nobel Prize in Medicine and Physiology 2024

Analysis

When it seemed that all functions of ribonucleic acids (RNA) had been studied and described, scientists discovered new types of RNA at the end of the 20th century that influence inheritance, development, and diseases. This year, the Nobel Prize was awarded for the discovery of one of these new RNAs. According to the Nobel Committee's decision, two American biologists, Victor Ambros and Gary Ruvkun, received the award in Physiology and Medicine for their "discovery of microRNA and its role in post-transcriptional gene regulation".
