In this episode, Buck scientist Brianna Stubbs sits down with Hanadie Yousef, Co-Founder of Juvena Therapeutics, to discuss the cutting-edge of longevity science. Dr. Yousef shares how Juvena is leveraging AI and the secretome—the proteins secreted by stem cells—to develop therapies that target muscle wasting and promote tissue regeneration. From the potential and risks of GLP-1 drugs to the role of AKT signaling in muscle health, this conversation explores how we can move beyond "snake oil" and into a future where science-based therapies help us stay younger, longer.

Dr. Hanadie Yousef is a scientist, entrepreneur, seasoned executive, and global thought leader in AI-driven regenerative medicine and longevity. With over two decades of experience in biomedical research, she is the Co-Founder of Juvena Therapeutics, where she served as CEO, CFO, and Board Chair from 2017 to 2025. Since the company’s incorporation, she pioneered its evolution from a platform-driven concept into a venture-backed, clinical-stage biotechnology leader. Under her leadership, Juvena secured over $105M in venture capital, non-dilutive grants, and partnerships, and developed a proprietary pipeline of tissue-restorative biologics for muscle and metabolic diseases.

Eric Verdin sits down with Dr. Cynthia Kenyon, a true pioneer in the field of geroscience and the Vice President of Aging Research at Calico. Dr. Kenyon recounts the revolutionary discovery that aging is not merely a process of "wearing out," but is a genetically regulated biological program. In 1993, Cynthia’s pioneering discovery that a single-gene mutation could double the lifespan of C. elegans roundworms while preserving function sparked an intensive study of the molecular biology of aging. The conversation explores how these findings translate from worms to mammals, the potential of drugs like Ozempic and Acarbose to extend human healthspan, and Dr. Kenyon’s proposal for a "World Healthspan Organization" to fund large-scale clinical trials for off-patent, low-cost compounds that currently lack traditional industry incentives.

Cynthia Kenyon graduated valedictorian in chemistry and biochemistry from the University of Georgia in 1976 and received her PhD from MIT in 1981. She then did postdoctoral studies with Nobel laureate Sydney Brenner at the MRC Laboratory of Molecular Biology in Cambridge, UK. In 1986, she joined the University of California, San Francisco as a Professor of Biochemistry and Biophysics. Dr. Kenyon is a member of the US National Academy of Sciences, the American Academy of Arts and Sciences, and the Institute of Medicine and she is a past president of the Genetics Society of America. She is now the Vice President of Aging Research at Calico.

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.
