Winners of the 2024 Nobel Prize in Physiology or Medicine Dr. Victor Ambros and Dr. Gary Ruvkun give a rare, extended joint interview about the road that led them to their discovery of miRNA in a roundworm, Dr. Ruvkun’s later discovery of miRNA in humans, how the scientists were both inspired at a young age by astronomy, what Dr. Ambros’ late father might have said about his son’s Nobel win, and a decades-old story from Dr. Ruvkun about a trip to Bolivia.
