In this captivating episode, we explore how Mark Bear's personal experience with congenital nystagmus sparked a revolutionary career in neuroscience. Mark shares his remarkable journey from struggling with a visual impairment to making groundbreaking discoveries about how the brain processes visual information, including the identification of a previously unknown neural pathway discovered during his undergraduate years.

The conversation delves deep into the fascinating mechanics of human vision, explaining how our brains transform input from two separate eyes into one unified visual experience. Perhaps most intriguingly, Mark reveals critical insights about the brain's developmental windows, particularly how infants must learn to see during their first year of life and why this ability has a strict deadline around age seven. This episode offers a unique blend of personal narrative and cutting-edge neuroscience, illuminating the remarkable plasticity of the human brain and the time-sensitive nature of neural development.

In this eye-opening episode, former Zapata Computing CEO Yudong Chen reveals the sobering truth about quantum computing's potential impact on drug discovery and the industry's inflated market expectations. Chen explains why even with perfect quantum chemistry calculations, the business case for quantum computing in pharmaceuticals falls dramatically short of the billions being invested, with a total addressable market of only around $100M.

The conversation takes fascinating turns as Chen shares the unusual origin story of Zapata Computing, named after Mexican revolutionary Emiliano Zapata, and traces the company's journey from quantum computing to AI. He provides crucial insights into the field's future, discussing the emerging quantum winter and why government funding, rather than venture capital, may be the path forward. The episode concludes with Chen's compelling vision for advancing quantum computing through focused application development and the need for standardized infrastructure.

Dr. David Huang shares the remarkable journey of how a failed laser surgery project during his MD-PhD studies at MIT led to the invention of Optical Coherence Tomography (OCT), now used in over 40 million eye procedures annually. The story includes a pivotal moment when Professor James Fujimoto volunteered as the first human subject for OCT testing when no other students would agree to have an experimental laser pointed at their eye.

The development of OCT was made possible by the 1980s telecommunications boom, which provided crucial fiber optic components. Dr. Huang's unique background combining computer science and medicine proved essential for creating this breakthrough technology. The conversation also explores OCT's rapid commercialization, its impact on treating age-related macular degeneration, and future developments including smartphone-based screening and potential applications for diagnosing brain and heart disease through retinal imaging.
