A beam of light that melts fat sounds like the cleanest shortcut imaginable, until you ask the real question: what else could it change about you? We’re joined by physician, scientist, and author Leonard Zwelling to talk about his medical thriller Light, inspired by real optogenetics research that uses light-responsive genes to influence brain circuits and behavior. The science is grounded, the “what if” is terrifying, and the line between healing and control gets blurry fast. 

We also get practical and current about weight loss, including why GLP-1 drugs can be life-changing for some people and still fail others through resistance or side effects. That gap opens the door to alternative “behavior therapies,” and Leonard’s story pushes it further by exploring unintended consequences like increased risk-taking. Once that possibility is on the table, the conversation turns to dual-use technology and the uncomfortable truth that the military and intelligence world will always notice tools that can shape human decisions. 

From there, we connect the dots to AI ethics in medicine and education: powerful diagnostic support, real privacy risks, classroom cheating, and the messy reality that AI still makes confident mistakes. Leonard also shares how he used AI tools to help self-publish, including formatting for KDP Amazon and iterating on a book cover, plus what it takes to get readers to actually pick up the book.
