We're not getting any younger... yet.
Why do some of us age gracefully and others don’t? How do our bodies and minds experience aging at the cellular and molecular level? Why do we even age to begin with? And maybe most importantly, can we do anything about it? Join hosts Eric Verdin, CEO of the Buck Institute in California, and Brianna Stubbs, Director of Translational Science at the Buck, as they speak with some of the brightest scientific stars on the planet to search for – and actually find answers to – these questions and many more.

Daniel Belsky: Measuring the Pace of Aging
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
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. Since 2020, he has been named an ISI highly-cited researcher.
