In this episode, we speak with Rick Doblin, founder of the Multidisciplinary Association for Psychedelic Studies (MAPS), about the decades-long mission to make MDMA-assisted therapy a legal treatment for PTSD and other mental health conditions. Rick received his PhD from Harvard's Kennedy School of Government in public policy focusing on the regulation of medical use of psychedelics in 2001. Rick shares the science behind MDMA’s therapeutic effects, the strategy for winning over regulators, and the battles over claims of neurotoxicity. We discuss the history of psychedelic research, the rise of the underground therapy movement, and how clinical trials, policy change, and cultural perception must align to move psychedelics from stigma to science.

Whether you’re curious about psychedelic science, drug policy reform, FDA clinical trials, or the future of mental health treatment, this conversation delivers expert insight into the intersection of research, regulation, and real-world impact.

Life’s First Blueprint Wasn’t DNA; it was RNA.

Read Jacob Fine’s latest publication here: https://www.sciencedirect.com/science/article/pii/S0022283625001901

Today we spoke with Jacob Fine, graduate student researcher in Computational Biology from the University of Toronto. We explore the physics of replication, the role of entropy and information theory, and how modern biology is reconnecting with theory to understand the most fundamental question in science. Our conversation takes place in a Russian sauna, where the hot and humid environment mimics some of the conditions needed for life to begin.

One of Keith Johnson’s final interviews: a brilliant mind on dark matter, water, and fusion.

Read about Keith’s legacy here: https://news.mit.edu/2025/keith-johnson-materials-scientist-independent-filmmaker-dies-0723

This episode is one of the final recorded conversations with MIT physicist Keith Johnson, who passed away just weeks after our interview. In this conversation, he unpacks his early research on the quantum structure of matter, his cold fusion theories, and how it all led to a screenplay about a young female physicist. Johnson also suggests a radical idea: water clusters in space might explain some aspects of dark matter. A one-of-a-kind interview that blends science, art, and speculation.

We’re honored to share this glimpse into Keith’s remarkable intellect, creativity, and curiosity. May his legacy continue to inspire.

In this episode of the 632nm podcast, Scott Aaronson shares his early fascination with calculus at age 11 and how “rediscovering” old mathematics led him toward groundbreaking work in complexity theory. He gives a lucid explanation of P vs NP, revealing how seemingly trivial questions about verifying solutions speak to some of the deepest unsolved problems in all of computing.

Aaronson also explores the frontiers of quantum computing, from the nuances of quantum supremacy experiments to the idea of quantum money and certified randomness. He explains how amplitudes—rather than straightforward probabilities—unlock powerful interference effects, yet still face limits imposed by measurement. The conversation concludes with a look at the future of fault-tolerant quantum computers and the possibility that we’ve finally reached the ultimate horizon of computability—unless nature has even stranger surprises in store.

In this episode of the 632nm podcast, we explore cutting-edge ideas in epigenetics and academic publishing. Oded Rechavi reveals how C. elegans worms defy conventional genetics by passing on traits through small RNAs, and discusses how these mechanisms might reshape our understanding of heredity. We also hear about a remarkable experiment hijacking Toxoplasma gondii—the so-called “cat parasite”—to deliver proteins into the brain, opening possible routes for new therapies.

Beyond the lab, we explore problems with modern publishing, from glacial review timelines to flawed incentives that push quantity over quality. Learn how AI-driven solutions might speed up peer review, allow scientists to focus on what truly matters, and help keep the spark of curiosity alive.

In this episode, Jeremy England reframes the origin of life debate by applying non-equilibrium physics, challenging the notion that life’s emergence must be purely biological or chemical. He describes how matter can “learn” from its environment, drawing on examples from spin glasses, protein folding, and resonating mechanical systems.

England also shares how his deep engagement with religious texts—and his unexpected cameo as “the next Darwin” in popular media—shaped his understanding of science and spirituality. From his ordination as a rabbi to his groundbreaking thermodynamic research, England offers a unique perspective on the interplay between faith, scientific inquiry, and the age-old search for meaning.

In this episode of the 632nm podcast, we sit down with 1517 Fund’s Danielle Strachman and Michael Gibson to explore their Flux program, a unique pre-seed fellowship backing wild, unorthodox scientific and technical ideas. They share how they’ve helped founders transform “garage science” projects—like nuclear batteries, quantum computing prototypes, and cutting-edge materials—into serious startups. Along the way, they discuss the pitfalls of chasing academic prestige, the power of genuine curiosity, and how to leverage minimal resources for big ambitions.

We also learn about the flexibility of Flux’s “cannon launch” grants, what it takes to persuade investors when your idea sounds like sci-fi, and why “hyper-fluency” and high agency are crucial for founders. Whether you’re a postdoc itching to leave the lab or a solo tinkerer with a radical concept, this conversation offers actionable insights on securing early funding and taking that bold plunge into world-changing tech.
