  1. Under Pressure: Training the Brain for Resilience

    28 APR

    Under Pressure: Training the Brain for Resilience

    Why do we struggle most when it matters most? In this episode of TEDMED Now, Kelly Thomas explores how pressure affects the brain, drawing on Sian Leah Beilock’s research on performance under stress. The episode reframes choking not as a lack of ability, but as a response to unfamiliar conditions. It also highlights how practicing under pressure can help us perform more effectively when the stakes are high. Key Moments When Pressure Takes Over (00:00) The Brain Under Pressure (01:20) From Flow to Overthinking (04:30) Training for Pressure (07:30) Rethinking Resilience (10:30) Quotes “Choking isn’t a failure of ability. It’s a mismatch.” “Resilient brains don’t avoid pressure. They learn how to operate inside it.” “Pressure is part of being human. But so is the capacity to adapt.” Resources Mentioned Below are links to the books, articles, and resources mentioned during the conversation. Beilock, S. L., & Carr, T. H. (2001).

Her research explores the science behind why people “choke” under pressure and how we can perform our best in stressful situations, whether it’s a big test, a public speech, or a championship game. By using a variety of research methods, from test performance to brain scans, she studies how our thoughts and reasoning skills change when we are under stress. KELLY THOMAS, PhD, is Director of Scientific Content at TEDMED, where she curates and translates breakthrough ideas at the intersection of science, medicine, and human potential. As  host of TEDMED Now, she explores resilience, behavior change, and the ways evidence-based science can shape longer, healthier, more meaningful lives.

  2. Never, Ever Give Up: The Power of the Human Spirit

    19 MAR

    Never, Ever Give Up: The Power of the Human Spirit

    What does it take to keep going when the odds say stop? In this episode, we explore the remarkable journey of endurance swimmer Diana Nyad, who spent decades pursuing one seemingly impossible dream: swimming 110 miles from Cuba to Florida without a shark cage.  At 64, after four failed attempts, brutal storms, jellyfish stings, hallucinations, and nearly 53 hours in the water, she finally made it to Key West. Along the way, we unpack the science of neuroplasticity, resilience, and how challenge, failure, and belief can rewire the brain to persist. Key Moments Diana Nyad’s mythic goal (00:16) Diana’s origin story (01:41) Why Diana returned to the dream at 60 (07:58) How failure becomes data (09:35) Where resilience lives (12:17) “Let’s find a way” (13:06) Lights of Key West reveal (13:50) Reflection on what Diana’s victory means (15:23) Never ever give up (16:39) Quotes “Failure isn’t a verdict, it’s feedback — raw data the brain uses to grow.” “That’s where resilience lives — between data and faith.” “Not let’s try again. Not let’s hope for the best. But let’s find a way.” Resources Mentioned Below are links to the books, articles, and resources: TEDMED Talk: Diana Nyad. “No Shortcuts to Victory.”  de Sousa Fernandes MS et al. (2020).
