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.

Our chronological age doesn’t tell us much about how well our bodies are aging, but scientists have developed many ways to measure changes at the cellular and molecular levels, including the rate of change, that can suggest ways to improve health at every stage of life. Follow along as Gordon speaks with Daniel Belsky of Columbia University about DNA methylation, the effects of famine and poverty on aging biology, studying the exposome, and how to create equitable access to potential aging interventions.

Dr. Belsky is an Associate Professor of Epidemiology in the Robert N. Butler Columbia Aging Center at Columbia University. His studies seek to understand how genes and environments combine to shape health across the life course. The goal of Dan's work is to reduce social inequalities in aging outcomes in the US and elsewhere. With collaborators Terrie Moffitt and Avshalom Caspi he originated the Pace of Aging method to quantify the aging process from longitudinal analysis of human physiology and recently translated this method into a DNA-methylation blood test that can be implemented from a single time point of data collection. He is principal investigator of NIH-funded projects to test how caloric restriction may slow or reverse aging-related changes to the genome (CALERIE), to understand long-term impacts of in-utero famine exposure on biological aging (Dutch Hunger Winter Family Study, with Bertie Lumey), and to test the potential of anti-poverty policy intervention to slow biological aging (MyGoals for Healthy Aging, with Peter Muennig). Dan's work has received international attention, including by the Wall Street Journal, Washington Post, and Guardian newspapers, and appeared in outlets including PNAS, Nature Human Behaviour, Nature Aging, the JAMA journals, Lancet Respiratory Medicine, and top journals in epidemiology and gerontology.
