Insight | First programs: how Knuth, Carmack, Fadell and Howard fell for computing
Donald Knuth started with a tic-tac-toe program on an IBM 650 in 1957, John Carmack's first program on a TRS-80 printed his name, Tony Fadell discovered programming on punch cards and an Apple II, Todd Howard programmed Star Trek clones on an Apple II, and ThePrimeagen describes falling in love with programming. Their stories show careers that began with small, playful programs on whatever machine was at hand, which is useful to anyone wondering how to start or how to draw a young person into the craft.

Insight | Buying supplements well: single ingredients, third-party testing and quality
Andy Galpin, Rhonda Patrick and Abud Bakri all stress that what is in the bottle, its form, its purity and where it was sourced, matters as much as whether to take it. Knowing how to judge quality keeps people from paying for products that are mislabeled, underdosed or risky.

Insight | Rogan's carnivore, St-Pierre's fasting, Barker's vegan and Harrelson's raw food diets
Joe Rogan credits carnivore eating with ending his overeating, easing his knees and clearing his head, Georges St-Pierre credits fasting with clearing his colitis symptoms, Travis Barker thrives on plant protein, and Woody Harrelson swears by raw living food. Their opposite experiments, and St-Pierre's own warning that everybody is different, show how personal diet results are and why one person's turnaround is not a rule for everyone.

Insight | Why American food makes people sick: Rogan's conversations and the Surgeon General
Across six conversations, Joe Rogan and his guests, along with Surgeon General Vivek Murthy, describe an American food supply shaped by heavy processing, additives, subsidies and industry pressure. They come from very different backgrounds and arrive at overlapping complaints, but they differ on how much to blame industry, how strong the evidence has to be, and what should change first.

Insight | Leaky gut explained: what five experts mean by it and how they repair it
Mark Hyman, Rajsree Nambudripad, Sara Szal, Robert Lustig and Andrew Huberman all describe a weakened gut lining as a driver of inflammation, and each points to specific foods, habits or compounds that make it worse or help it heal. Comparing their accounts shows where the idea is concrete and where the explanations differ.

Insight | Race to the bottom or the top? Moloch and the rivalry between AI labs
Max Tegmark calls the competition between AI labs Moloch's suicide race, Daniel Kokotajlo proposes transparency instead of a race, Nick Bostrom weighs superintelligence timelines and the race alongside governance, Dario Amodei describes Anthropic's race-to-the-top strategy, Sam Altman takes up competition, capped profit and the problem of power, and Sundar Pichai describes leading Google through the AI race. Seeing how each one explains the pressure to move fast, and what each would do about it, shows why safety promises are hard to keep when every lab fears falling behind.

Insight | Broccoli sprouts, sulforaphane and xenohormesis: the case for plant compounds
Rhonda Patrick explains sulforaphane from broccoli sprouts and moringa, David Sinclair discusses xenohormesis and antioxidants, Andrew Huberman cites sulforaphane as a help for clearing microplastics, and Mark Hyman champions phytochemicals. It gives a reason to eat a wide range of plants that goes beyond their vitamins.

Insight | Can you measure your biological age? Clocks, telomeres and the doubts
David Sinclair describes clocks for measuring biological age, Elizabeth Blackburn and Elissa Epel present telomeres as setting the pace of cellular aging, and Peter Attia looks at biological age tests within a skeptical review of longevity claims. It helps readers decide whether a biological age result is worth acting on.

Insight | Does fasting cost you muscle? Fung, Lyon, Norton and Huberman weigh in
Jason Fung sets out to bust the muscle-loss and starvation-mode myths, while Gabrielle Lyon, Layne Norton and Andrew Huberman's fasting episodes discuss fasting alongside protein timing, protein synthesis and the needs of muscle. The answer matters for anyone who wants the benefits of fasting without giving up strength.

Insight | Looking after the prostate: urinary health, cancer worries and testosterone
Michael Eisenberg covers prostate and urinary health and prostate cancer in two conversations, Rena Malik discusses prostate health with the urologist's view of the pelvis, Kyle Gillett includes the prostate in male hormone care, and Brigham Buhler takes on the fear that testosterone causes prostate cancer. Men get several perspectives in one place, including where testosterone fits.

Insight | Red and near-infrared light: what its advocates say it does
Roger Seheult links infrared light to mitochondria and melatonin, Andrew Huberman's light and skin episodes cover red and near-infrared light for skin and other tissues, Rowan Jacobsen discusses red light alongside sun and mood, and Gary Brecka builds light into his morning routine. Laying out what each claims, and the evidence they point to, helps readers judge a popular wellness tool.

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 | Can diet lower dementia risk? Insulin, junk food and the aging brain
Max Lugavere treats dementia as a disease of midlife tied to insulin resistance and ultra-processed food, Lisa Mosconi explains which foods and habits protect women's brains from Alzheimer's, Scott Kanoski describes rodent studies in which sugar and junk food impair memory, Calley and Casey Means frame Alzheimer's as a brain energy problem, Tommy Wood covers nutrition and dementia risk, and Chris Palmer discusses Alzheimer's and ketones. If the brain's decline begins decades before symptoms, everyday eating becomes one of the earliest levers anyone has.

Insight | Taming blood sugar spikes: food order, movement and glucose monitors
Andrew Huberman's hunger, sugar and fasting episodes cover the order you eat foods in, the glycemic index, walks and exercise for stable blood sugar, Casey Means recommends walking and movement breaks and explains what a continuous glucose monitor can teach you, Sara Gottfried describes using glucose monitors with PCOS, and Rangan Chatterjee explains one-ingredient foods and the blood sugar roller coaster. These are small daily habits, which makes them an easy place to start before any bigger change in diet.

Insight | Code is written for people: Knuth, Guido and the Hitchhiker's Guide on readability
Donald Knuth explains in two conversations why he writes programs as literature through literate programming, Guido van Rossum describes programs as recipes written for two audiences and digs into code readability, and The Hitchhiker's Guide to Python devotes its core chapters to writing and reading great code. Treating the human reader as the main audience changes how programmers name, structure and explain their work, and makes code easier to maintain.

Insight | Why AI runs on Python: NumPy's creator, Anaconda's CEO and Mojo's designer explain
Travis Oliphant tells how NumPy united a split community and became the foundation of array and tensor computing in Python, Peter Wang explains what made him fall in love with Python and why the scientific Python stack emerged as it did, and Chris Lattner builds Mojo as a superset of Python because of Python's strengths. Their accounts explain how a language designed for readability ended up as the working language of science and AI, and what its builders are doing about its speed.

Insight | Written for people first: readability, indentation and great Python code
Guido van Rossum describes programs as recipes written for two audiences and explains why readability matters, Chris Lattner weighs Python's strengths and the indentation debate while building Mojo on top of it, and The Hitchhiker's Guide to Python gives whole sections to writing and reading great code. Together they show why the people who build and teach Python treat code as something humans must read, not only something a machine must run.

Insight | Willpower or food environment? Who gets the blame for chronic disease
Robert Lustig weighs personal responsibility against public health and the food industry, Vivek Murthy describes processed food, additives and industry pressure, Calley and Casey Means argue industry has captured health institutions, Brigham Buhler ties food chemicals to metabolic disease and Jason Fung says environment and habit beat willpower. Where you place the blame decides whether the fix is personal discipline, a changed food environment or new rules for the industry.

Travis Barker describes his plant-based eating and Woody Harrelson his raw vegan living, while Mark Hyman lays out his pegan approach and discusses meat, soil and regenerative agriculture, Gabrielle Lyon discusses red meat, the environment and animal versus plant protein quality, Layne Norton compares plant and animal protein, Marie-Pierre St-Onge describes plant-forward eating and rancher Taylor Sheridan challenges the myth of harmless eating. Seeing health, protein quality, ethics and the environment argued side by side shows which parts of the debate are about nutrition and which are about values.

Insight | Hunger is a forecast: how the brain predicts and remembers meals
Andrew Huberman explains that hunger has accelerators, brakes and a clock and that ghrelin follows your eating schedule, Zachary Knight describes AgRP neurons that predict a meal before the first bite, and Scott Kanoski shows that memory helps decide how much we eat. Seeing hunger as something the brain anticipates and learns, rather than a simple signal from an empty stomach, shows why an empty stomach is not the only thing that drives eating.

Insight | Cancer risk you can change: screening, metabolism, alcohol and immune defenses
Jason Fung describes cancer as a seed that needs the right soil, Peter Attia and Chris Thompson argue for earlier and better screening, and immunologists explain why tumors slip past the body's defenses. Together they show which parts of cancer risk a person can act on and where the experts still disagree.

Insight | Never too late: what starting to train after 50 delivers
Vonda Wright rejects the idea that decline is inevitable, Layne Norton and Pavel Tsatsouline explain how to lift safely later in life, and performers in their seventies describe getting stronger than they were at 50. Their accounts answer the common worry that the window for building strength has already closed.
