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.

In this episode, physicist Federico Capasso recounts his winding path from struggling undergrad to pioneering inventor of the quantum cascade laser. He reveals how openness, daring ideas, and the bottom-up ethos at Bell Labs led to breakthroughs that redefined semiconductor research.

Capasso also discusses the blurred lines between basic and applied science, the importance of nurturing curiosity, and the serendipitous moments that propelled his career. From avalanche photodiodes to metasurfaces to quantum biology, he offers a fascinating look at how big discoveries often begin with a simple spark of wonder.

Eli Yablonovitch shares how Thomas Edison's approach of requiring "a thousand failed discoveries for every one that works" shaped his scientific philosophy. From solar cells to semiconductor lasers to photonic crystals to cell phone antennas, Yablonovitch reveals how each invention evolved from identifying fundamental physics concepts that others overlooked. He explains how his light-trapping concept now used in every solar panel stemmed from thinking about statistical mechanics. His strained semiconductor laser design, which initially faced industry resistance, eventually became the standard in all laser pointers and DVDs. Throughout his career spanning Bell Labs, Exxon, and academia, Yablonovitch demonstrates that true innovation comes from understanding basic physics principles and having the courage to pursue ideas others dismiss as impossible.

Join the 632nm team as we sit down with Nobel laureate Dr. John Mather. From his childhood days of building radios and telescopes to leading NASA's groundbreaking COBE mission, learn how a spectacular failure during his PhD research unexpectedly paved the way for his Nobel Prize-winning work. And hear the story of how NASA took a chance on a 28-year-old scientist who would change our understanding of the universe.

Dr. Mather shares insights into the engineering marvels behind modern space telescopes, including the James Webb Telescope's ingenious cooling system and the concept behind hybrid ground-space observatories. Hear details about near-mission failures, midnight revelations that saved COBE, and the surprising connection between space telescopes and stealth fighter technology.
