"How We Age: The Science of Longevity" (Professor Coleen Murphy, Princeton)

Dr. Coleen Murphy is a prominent aging researcher and author of the upcoming book “How We Age: The Science of Longevity” from Princeton University Press. In this wide-ranging discussion, Coleen provides insights into her motivation for writing this book, key topics covered, and her unique perspective on the field. 

Key ideas:

Addressing ethical concerns about studying aging and longevityDefining aging conceptually and how metrics like lifespan vs. healthspan are measuredUsing genetics, transcriptomics and other tools to understand molecular changes in agingThe prominent role of reproduction and sex differences in agingTheories on tradeoffs between reproduction and longevityGenetics of aging pathways including insulin/IGF-1, mTOR, and sirtuinsCellular processes involved in aging such as mitochondrial dysfunction, epigenetic changes, senescenceThe importance of models like C. elegans and Drosophila in aging researchOngoing research and future potential for interventions to increase healthspanThe challenge of complex science without excessive jargonHighlighting critical contributions by women scientists in the fieldOmitting personal lifestyle advice and focusing on evidence-based scienceThe rapid pace of advancement in biotech applications of longevity science
