A long-simmering conversation about creatine cuts through the supplement industry’s salesmanship with a sober look at what the research actually supports. Exercise scientist Eric Rawson traces the compound’s history, explains how it works in muscle and brain, and argues that its benefits are real while the old fears about cramps, kidneys and other harms have largely failed to materialize.

Mark Rober talks with Molly Graham about resisting the churn of the creator economy by treating YouTube less like a slot machine than a long game. The former NASA engineer traces his success to calculated risk, obsessive quality control, and a stubborn commitment to building work, money, and ambition at a pace he can actually sustain.

Riyaz Factory’s founders describe a biologically driven alternative to plastic recycling, using enzymes and AI to break polymers back into their original monomers instead of degrading them with heat. Their conversation traces the science, the limits of traditional recycling, and a startup effort to build a low-energy circular process that could plug into existing industrial supply chains.

Bruce Daisley talks with journalist Kate Murphy about the elusive chemistry of human connection, and what her research into synchrony suggests about teamwork, meetings and the limits of digital communication. Their exchange moves from the contagion of a single workplace "bad apple" to the rare colleague whose presence can steady a room.

Cognitive scientist Maya Shankar argues that sudden upheaval can shatter the identities people build around work, but also open the door to a sturdier sense of self. Drawing on her own career-ending violin injury and research on resilience, she offers a case for anchoring identity to purpose rather than title, and for treating disruption as a chance to grow into someone new.
