We're not getting any younger... yet.

What if the secret to a longer, healthier life isn’t found in a new supplement or a complex medical procedure, but in your cells' own innate ability to "take out the trash"? In this episode, host Eric Verdin is joined by Dr. Ana Maria Cuervo, a pioneer in the biology of aging and professor at the Albert Einstein College of Medicine. The conversation explores the critical roles of proteostasis—the cell's protein quality control factory—and autophagy, the body's natural recycling system. Dr. Cuervo explains her discovery of Chaperone-Mediated Autophagy (CMA) and how keeping these cellular "cleaning crews" active can help prevent neurodegenerative diseases like Alzheimer’s and Parkinson’s. The episode concludes with actionable insights into how sleep, exercise, and meal timing can naturally jumpstart these longevity-promoting pathways.
Ana Maria Cuervo is a Spanish-American physician, researcher, and cell biologist. She is a professor in developmental and molecular biology, anatomy and structural biology, and medicine and co-director of the Institute for Aging Studies at the Albert Einstein College of Medicine. She is best known for her research work on autophagy, the process by which cells recycle waste products, and its changes in aging and age-related diseases.

XPRIZE Healthspan Executive Director Jamie Justice joins Brianna Stubbs to discuss the $101 million race to restore 10 years of muscle, cognitive, and immune function within a single year. Moving past binary "alive or dead" metrics—famously called the "toes test" in animal research—the conversation focuses on reclaiming functional independence through clinical trial innovation. Together they explore the potential of accessible markers like RDW (Red Cell Distribution Width), the risks of overlapping treatments, and how unlocking "dark data" can help shift medicine from treating isolated diseases to scaling human healthspan globally.

Jamie is the Executive Vice President of the Health Domain at XPRIZE Foundation, and Adjunct Professor in Internal Medicine Section on Gerontology and Geriatric Medicine, and Sticht Center on Healthy Aging and Alzheimer’s Prevention at Wake Forest University School of Medicine (WFUSM). She is dedicated to Geroscience research that advances the hypothesis that by targeting the basic biology of aging the incidence of multiple age-related diseases can be delayed or prevented.

In this episode, Eric Verdin, CEO of the Buck Institute, and Stanford University’s Dr. Tony Wyss-Coray discuss the groundbreaking science of brain rejuvenation through heterochronic parabiosis, a process where young blood factors are shown to restore cognitive function and potentially extend lifespan. Moving from the lab to the clinic, they explore the next frontier: Proteomic Clocks. By measuring thousands of proteins, scientists can now determine the biological age of individual organs, allowing for the detection of Alzheimer’s and other neurodegenerative diseases up to 15 years before symptoms appear. This shift toward high-precision organ tracking marks a new era in preventative geroscience and personalized longevity.

Tony Wyss-Coray is a Professor of Neurology and Neurological Sciences and the Director of the Phil and Penny Knight Initiative for Brain Resilience at Stanford University. His lab studies brain aging and neurodegeneration with a focus on age-related cognitive decline and Alzheimer’s disease. The Wyss-Coray research team discovered that circulatory blood factors can modulate brain structure and function and factors from young organisms can rejuvenate old brains. Current studies focus on the molecular basis of the systemic communication with the brain by employing a combination of genetic, cell biology, and –omics approaches in killifish, mice, and humans. Wyss-Coray has presented his ideas at Global TED, the Tencent WE Summit, and the World Economic Forum. He co-founded Alkahest Inc. and several other companies targeting Alzheimer’s and neurodegeneration and has been the recipient of an NIH Director’s Pioneer Award, a Zenith Award from the Alzheimer’s Association, and a NOMIS Foundation Award.

What if aging is less a fate and more an engineering challenge? We sit down with George Church to unpack a future where gene therapy, cellular reprogramming, and AI-driven delivery systems converge to extend healthspan—and possibly lifespan—without sacrificing identity or safety. From bowhead whales and cancer risk to ethics, trial rigor, and how to deliver rejuvenation to the brain, this is a deep dive into what’s coming next and what it will take to get there.
George Church is Professor of Genetics at Harvard Medical School and Professor of Health Sciences and Technology at Harvard and the Massachusetts Institute of Technology (MIT). He is Director of the U.S. Department of Energy Technology Center and Director of the National Institutes of Health Center of Excellence in Genomic Science. He has received numerous awards including the 2011 Bower Award and Prize for Achievement in Science from the Franklin Institute and election to the National Academy of Sciences and Engineering.
