Insight | Seed oils on trial: Norton, St-Onge and Brecka weigh in
Layne Norton takes up seed oils in his conversations with Andrew Huberman, Marie-Pierre St-Onge discusses them alongside the problem of industry-funded research, and Gary Brecka groups them with everyday toxins. Setting the positions side by side shows what evidence each one leans on.
Insight | Your brain talks to your immune system: breathing, heat and memory
Andrew Huberman's immune episodes describe how the nervous and immune systems signal each other, with tools from sauna to cyclic hyperventilation and its E. coli study, Max Krummel describes memories that can recall immune states, and Huberman's pain episodes cover Wim Hof breathing, the stress response and inflammation. It suggests that part of immune defense can be steered through the nervous system.
Insight | The fat you can't pinch: why visceral fat worries so many experts
Rhonda Patrick, Stacy Sims, William Li, Shawn Stevenson, Mary Claire Haver and Robert Lustig each separate the deep fat around the organs from the fat under the skin, and several explain how to spot it, from the idea of being skinny fat to the three fat depots, and how to bring it down. Knowing which fat is which changes what a reader tracks and explains why the scale alone can mislead.
Insight | Humans to Mars soon, robots first, or floating cities instead?
Martin Rees weighs robots against human pioneers on Mars, Jim Gates doubts a Mars landing by 2030, Ariel Ekblaw argues floating cities may beat Mars, Adam Frank discusses Mars and space habitats, and Brian Greene talks about the engineering of exploration. Comparing them separates the timelines and the reasons for sending people from the enthusiasm.
Insight | Who you train with: champion-making rooms from Dagestan to Austin
Khabib Nurmagomedov describes Dagestan's coaches and constant competition, John Danaher explains how his team broke apart and then rebuilt for ADCC, the B-Team grapplers describe the split and how they run their gym, and Matt Serra's group discusses loyalty to gyms. For anyone choosing a gym or team, these accounts show what the people in the room add and what happens when a team breaks apart.
Insight | Tap early, train for years: jiu-jitsu advice for hobbyists
Roger Gracie says he never quits but always taps, John Danaher gives advice for hobbyists, the B-Team grapplers cover injuries, warm-ups, training weeks and advice for hobbyists, and Bryan Callen and Joe Rogan talk about training jiu-jitsu for the long haul.
