Huberman Lab

Dr. Beth Shapiro, PhD, is an evolutionary biologist and Chief Science Officer at Colossal Biosciences. Her work focuses on de-extinction and wildlife conservation efforts. We discuss genetic differences among humans, and how ancient DNA and modern embryology are being used to de-extinct and protect woolly mammoths, dodo birds, and dire wolves, as well as to help conserve endangered species. We also explore the ethical implications of de-extinction and how synthetic biology can help build a more bio diverse and resilient world. Read the full episode show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, I explain how the neurochemicals epinephrine, acetylcholine and dopamine contribute to focus and concentration. I discuss tools for improving attention, including sleep, sound, structured work sessions, nutrition, caffeine and deliberate cold exposure. I also describe a brief daily meditation and visual focus exercises that train your ability to refocus when attention drifts. Additionally, I discuss the potential benefits and limitations of supplements, prescription treatments for ADHD, and why taking time to deliberately defocus supports concentrated work.

In this Huberman Lab Essentials episode, I revisit episode 2 of my six-part guest series with Dr. Andy Galpin, PhD, an exercise scientist and expert in human performance. We discuss how strength and muscle growth (hypertrophy) differ and why resistance training is important for maintaining physical function as we age. We also explain how to build effective training programs using progressive overload, exercise selection, repetition speed and weekly training volume. Dr. Galpin shares practical tools for developing strength, power and muscle size, including how to adapt workouts to your goals, equipment and schedule.

Dr. Chris Thompson, MD, Professor of Medicine at Harvard Medical School, Chief of Interventional Gastroenterology at Mass General Brigham in Boston, and Co-Director of the Center for Weight Management and Wellness, is a world-renowned expert on gastroenterology, metabolism, nutrition, and obesity medicine. He explains how your GI tract regulates hunger, fullness, and blood sugar, as well as the gut microbiome, metabolic health, and weight loss. We also discuss common GI tract issues and which particular tests or interventions are actually useful. We discuss both GLP-1 medications and non-GLP-1 approaches to weight loss. Given that gut health is vital to all the organs of the body, overall health, and longevity, our discussion ought to be of interest and practical value to everyone, including, of course, those struggling with gut health or weight loss challenges.
