Huberman Lab catch-up — Fri 9 Oct 2026

Daniel Brooks

Here's your Huberman Lab catch-up. It's Friday the ninth of October, and you've got eight Huberman Lab episodes you haven't played yet. That's roughly twelve hours of audio, and I'll take you through each of them in about fifteen minutes, starting with the most recent. For each one you'll get the guest, the useful protocols, and whether I think it's worth your time. Everything here comes from the episode transcripts. It's what the guests said on the show, not medical advice.

Daniel Brooks

First up, from the fifth of October: Dr. Beth Shapiro, two hours and sixteen minutes. She's an evolutionary biologist, formerly at UC Santa Cruz, and now chief science officer at Colossal Biosciences, the de-extinction company. The headline is the dire wolves. Colossal sequenced fossil dire wolf genomes, picked twenty edits that made the animals bigger, more robust and lighter-coated, and engineered those changes into a gray wolf genome. She also explains why dinosaurs aren't happening. DNA breaks down after death through UV damage, freezing and thawing, and other processes, and the oldest DNA ever recovered is from a mammoth bone of roughly one to two million years old, while dinosaurs died out more than sixty-six million years ago. Mammoths are feasible because Asian elephants share about ninety-nine percent of their genome, but she doesn't want a hundred elephants carrying twenty-two-month pregnancies, so Colossal is working on artificial wombs. Her answer to "why not save living species instead" is that they use the same tools for both. Alongside the dire wolves they announced cloned red wolves to add genetic diversity to that critically small population. There's also a thoughtful stretch on embryo screening and gene editing in humans. Verdict: there's nothing here for you to do, but it's fascinating science. Listen to the first hour if de-extinction interests you, and skip it if you want practical tools.

Second, from the first of October: Essentials, Tools to Improve Your Focus and Concentration. This is a forty-one-minute solo episode, and it's packed with protocols. Huberman's model is an arrow. Epinephrine is the shaft, giving you alertness. Acetylcholine is the arrowhead, the spotlight. Dopamine keeps you going. The tools: sleep well on about eighty percent of nights. White, pink or brown noise can shorten the time it takes to drop into focus. Work in bouts of up to ninety minutes, and count the first five to ten minutes as warm-up. Eat lightly if you want to focus afterwards, because a full stomach pulls you into rest-and-digest. Caffeine works for focus anywhere from one hundred to four hundred milligrams, though most people do well on one hundred to two hundred, and he says to stop at least eight hours before bed, ideally ten to twelve. A one-to-five-minute cold shower raises epinephrine and dopamine. Then there's the meditation from Wendy Suzuki's lab: thirteen minutes a day of nasal breathing with your attention about an inch behind your forehead. Each time your mind drifts and you bring it back counts as a rep, not a failure. The visual drill: stare at one spot for thirty seconds, add five seconds a day, and work up to three minutes before a work bout. On supplements, he covers one to three grams of EPA, five grams of creatine, and what he takes himself: alpha-GPC with a six-hundred-milligram garlic capsule, and L-tyrosine. Verdict: worth the full forty minutes. It's the most actionable episode in the pile.

Third, from the twenty-eighth of September: Michael Pollan, two hours and three minutes, on his new book about consciousness, A World Appears. He separates sentience, a basic awareness of your surroundings that plants and even single cells may have, from the richer, self-reflective consciousness humans have. He's persuaded by the line of work from Antonio Damasio and Mark Solms that consciousness begins with feelings in the brainstem, things like hunger, warmth and itch, rather than with thought in the cortex. If that's right, many more animals are conscious. He's skeptical that silicon AI can be conscious, because on that view feelings need a vulnerable body. He keeps an open mind on the brain as a receiver rather than a generator, notes that you can have consciousness without a self in meditation or on psychedelics, and tells how he quit caffeine for three months and found his first cup back better than any psychedelic. Verdict: big ideas, with almost nothing to act on. Save it for a long drive.

Fourth, from the twenty-fourth of September: Essentials with Dr. Andy Galpin on building strength and muscle, thirty-eight minutes. His case: strength training is the only tool against neuromuscular aging. After about forty you lose roughly one percent of muscle size a year, two to four percent of strength, and eight to ten percent of power. For strength and power, use the three-to-five rule. That means three to five days a week, three to five exercises, three to five reps, three to five sets, and three to five minutes of rest, done with high intent. Do them first in the session, while you're fresh, and add three to five percent load a week for five to eight weeks before a deload. Pick movements rather than muscles: upper and lower, push and pull, plus some rotation. Keep your exercises the same for at least six weeks. For hypertrophy, aim for at least ten hard sets per muscle group a week, more realistically fifteen to twenty, stopping about two reps short of failure. Three full-body sessions a week holds up best against a busy life. Verdict: a great half-hour if you lift. It's a compact program you can use straight away.

Fifth, from the twenty-first of September: Dr. Chris Thompson on the best tools for gut health and weight loss, two hours and twenty-eight minutes. Thompson is an interventional gastroenterologist at Harvard and Mass General Brigham. His core line is to feed your microbes fiber, or they'll eat your mucus layer, stop making butyrate, and weaken the tight junctions in your gut wall. He calls increased gut permeability "a hundred percent real." The practical points: about thirty-five grams of fiber a day for men and twenty-five for women, plus fermented foods like kefir, kimchi, sauerkraut and yogurt alongside the fiber, not instead of it. Start colon cancer screening at forty-five, or at forty if there's family history. On GLP-1 drugs, he says about thirty percent of people stop in the first month and about half by the end of the year. On semaglutide, roughly a third of the weight lost can be lean mass, so lift weights and have a plan for coming off: a micro-dose or a procedure, not casual cycling. He developed endoscopic sleeve gastroplasty, which he puts at about eighteen percent weight loss, and up to around twenty-five percent when combined with ablating the cells that make the hunger hormone ghrelin. Verdict: worth it if GLP-1s or metabolic health are on your radar. Otherwise the fiber and fermented-food takeaways are the part to keep.

Sixth, from the seventeenth of September: Essentials with Andy Galpin on assessing your fitness, thirty-six minutes. It's a do-it-yourself test battery. The benchmarks are: a standing broad jump of about your own height, around fifteen percent less for women. Grip strength of at least forty kilograms for men and thirty-five for women, ideally sixty, with less than ten percent difference between hands. A dead hang of at least thirty seconds, with sixty being good. A leg extension at your body weight, minus about ten percent per decade after forty. A goblet squat hold at half your body weight for forty-five seconds. Twenty-five push-ups for men, fifteen for women. A front plank for sixty seconds. Heart rate recovery of about thirty beats in the first minute after a max effort. A fat-free mass index of twenty or more for men and eighteen for women. And for VO2 max, measured or estimated with a twelve-minute Cooper run, at least thirty-five for men and thirty for women, with above fifty being the real goal. He suggests doing the full battery once a year over about three days. Verdict: worth it, and a good one for planning next year's training.

Daniel Brooks

Seventh, from the fourteenth of September: Dr. Arthur Brooks on the art of true happiness, the longest of the batch at two hours and fifty minutes. His framework: happiness isn't a feeling. It has three macronutrients, enjoyment, satisfaction and meaning, and each of them contains some unhappiness. Enjoyment is pleasure plus people plus memory. His rule of thumb is that if you're doing something pleasurable alone, it's probably pleasure rather than enjoyment. Proper leisure means deepening relationships on purpose, learning something you don't need to learn, and spending time on the philosophical or spiritual side of life. Satisfaction comes from progress after struggle, which is why reaching a goal often feels flat. For meaning, he says to name your idol among money, power, pleasure and fame, because chasing it as an end in itself costs you love. Break the tech habit by keeping devices away for the first hour of the day, the last hour, and at meals, and ask what he calls un-Googleable questions, like "why am I alive?" Verdict: long, but Huberman calls it one of his favorites. If you're short on time, the first hour covers the whole framework.

Daniel Brooks

Eighth, from the tenth of September: Essentials with Dr. Oded Rechavi on whether memories can be inherited, thirty-six minutes. In mammals, roughly ninety percent of the chemical marks on DNA are wiped clean between generations. But in the C. elegans worm, which has nine hundred and fifty-nine cells, three hundred and two of them neurons, and a three-day generation time, his lab showed that small RNAs can carry information to offspring. Parents' antiviral RNAs protect their descendants, and RNA changes made only in the brain altered food-seeking behavior for several generations. He's clear that none of this has been shown in humans. The near-term idea is RNA-based screening for couples alongside DNA tests, and he notes rodent studies where exercise in parents corrected harmful effects of overfeeding in their offspring. Verdict: elegant science, but optional, with nothing for you to do yet.

Now the top actions across these episodes. One: work in focus blocks of up to ninety minutes, start with thirty seconds of visual fixation, and cut off caffeine eight to ten hours before bed. Two: try thirteen minutes a day of breath-focused meditation, and count every refocus as a rep. Three: lift with the three-to-five rule for strength, and get ten to twenty hard sets per muscle group a week for size. Four: run Galpin's test battery once a year, starting with grip, broad jump, push-ups and VO2 max. Five: get around thirty-five grams of fiber a day plus fermented foods, and book colon screening if you're forty-five or older. Six: keep phones out of the first hour, the last hour and meals, and spend your leisure on people and learning. If you only listen to one in full, make it the focus Essentials, with the Thompson gut episode second.
