Nobel Laureate Dr. Venki Ramakrishnan and neuroscientist Dr. Vidita Vaidya explore the ideas in Why We Die: The New Science Of Ageing And The Quest for Immortality, Ramakrishnan’s compelling study of the biology and meaning of mortality. The conversation traces how cells age, why evolution built limits into life, and how the brain responds to this knowledge. Combining insight and inquiry, it reflects on what science can teach us about living fully, and facing the end with grace.
