Azra Raza, MD, is a world leading cancer physician scientist and Professor of Medicine at Columbia University, where she directs the Myelodysplastic Syndrome Center. For more than four decades, she has been at the forefront of research into blood cancers, with a particular focus on detecting cancer at its very earliest stages. She is also the author of the acclaimed book The First Cell, which challenges how we think about cancer research, treatment, and prevention. Dr. Raza is widely respected not only for her scientific contributions, but for her powerful advocacy for a more humane, patient centered approach to cancer. 00:00 Intro 06:15 The Unique Challenges of Blood Cancers 13:21 The Importance of Early Diagnosis: Finding “The First Cell” 19:42 A Patient-Centered Approach: The Human Cost of Cancer Treatment 24:13 A Waste of Financial and Intellectual Resources: The Current State of CancerResearch 29:15 Exploring New Technologies in Cancer Research: AI, Multi-omics, SpatialBiology, Nanotechnology 35:59 Developing “Implantable Intelligence” to Detect Cancer 40:34 The Future of Healthcare and the Role of AI

#17 Jonathan Metzl on Firearm Control, Vaccine Mandates, and the Rural Pushback Against Government

Jonathan Metlz, MD, PhD, joins Nick Dirks to discuss his educational journey that combined the sciences with the humanities, firearm culture in the American Heartland, and the growing skepticism of institutional expertise. Prof. Metzl is a physician, psychiatrist, sociologist and public intellectual whose scholarship and commentary explore the intersections of health, race, identity and violence in America. He currently holds the Frederick B. Rentschler II Professorship in Sociology and Psychiatry and directs the Department of Medicine, Health, and Society at Vanderbilt University. His path-breaking books – such as Dying of Whiteness and What We’ve Become – challenge conventional public-health narratives about gun violence, mental illness and race. His work asks what it means to be healthy, safe and free in a deeply divided society.

#14 Britney Schmidt on Robotic Submersibles, Rising Sea Levels, and the Potential of Extraterrestrial Life

Britney Schmidt, PhD, joins Nick Dirks to discuss what we can learn from earth’s harshest environments, what the Thwaites Glacier tells us about rising sea levels, and why she believes Europa deserves more attention than Mars. Dr. Britney Schmidt is a planetary scientist, glaciologist, and astrobiologist whose groundbreaking work explores the hidden oceans beneath ice worlds – both on Earth and beyond. Currently Associate Professor at Cornell University and Principal Investigator of the Planetary Habitability and Technology Lab, Dr. Schmidt leads major NASA- and NSF-funded projects, including the development of robotic submersibles to study Earth’s subglacial lakes and Europa's potential ocean, helping us understand habitability in the solar system and resilience in the face of climate change. In 2024, Prof. Schmidt was named a Blavatnik Awards for Young Scientists Laurate [https://blavatnikawards.org/honorees/profile/britney-e-schmidt/], which is administered by the Academy in collaboration with the Blavatnik Family Foundation [https://blavatnikfoundation.org/]. 00:00 Intro 02:15 From the Deserts of Arizona to the Ice Sheets of Antarctica 05:42 ICEFIN: Robotic Submersibles Studying Ice at the Bottom of the World 11:11 Measuring Ice Melt in the Underbelly 18:00 Interdisciplinary Research: Planetary Science Meets Physics and Engineering 25:26 Aliens on Our Own Planet: Observations from 530 Meters Beneath the Ice Shelf 31:24 Studying the Pace and Physics of Ice Melt 39:17 Rising Sea Levels: Correcting the Problems and Treating the Symptoms 43:38 The Impact of Funding Cuts for Scientific Research 47:22 Why Europa Deserves More Attention than Mars
