Leary, Good Friday and the ban: revisiting the first psychedelic research wave
Michael Pollan traces the first wave of psychedelic research from its promise to its crack-up, Rick Doblin tells Lex Fridman about Timothy Leary and the Good Friday Experiment and tells Joe Rogan about the honest follow-ups of the Good Friday and Concord Prison studies, Norman Ohler explains why LSD was banned, and Dr. Mark Gordon discusses psychedelics, veterans and the 1970 drug laws. Knowing how the first wave of research began and ended gives context for the psychedelic trials being run today.
Why time crawls and flies: how the brain warps your sense of time
David Eagleman explains why time seems to slow down during a fall, and Andrew Huberman answers a live audience question on why time speeds up and slows down and links blinking to time perception in his ADHD episode. Together they treat the sense of time as something the brain produces, which helps explain why the same hour can feel endless or vanish.
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.
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.
Turning Back the Clock: Age Reversal, Escape Velocity and What Is Actually Proven
David Sinclair reports that a cellular reprogramming therapy has entered its first human trial, Ray Kurzweil forecasts more than a year of added life expectancy per year by the end of the decade, and Nick Bostrom and Michael Levin add what ending aging would demand and another biological route to it. The sources contain no outside critic of these claims, so this piece sorts each one by its evidence: shown in animals, shown in human cells, under test in people, or still a prediction.
Your mouth is a health organ: oral bacteria, fluoride and whole-body disease
Dentist Staci Whitman and Huberman's oral health episode treat the mouth as a living ecosystem that teeth repair within, and warn that harsh mouthwash and constant snacking damage it, while James Nestor ties shrinking jaws to breathing problems. Looking after the mouth turns out to protect far more than teeth.
Erectile dysfunction as an early warning: blood flow, not hormones
Urologists Michael Eisenberg and Rena Malik say most erectile problems come from blood vessels and the pelvic floor and often appear before heart disease does, and Kelly Starrett and Kyle Gillett add the movement and lifestyle side. Men who treat it as a health signal get a chance to fix the cause early.
Growth hormone: the youth hormone that may not lengthen life
Clinics offer growth hormone and drugs that release it to restore youthful muscle and skin, and Kyle Gillett and Craig Koniver describe using them, yet David Sinclair notes that lower growth signaling goes with longer life and Huberman lists the risks of injecting it. The contrast shows why feeling younger and living longer are not always the same goal.
Reversing type 2 diabetes: what Fung, Attia and Means say works
Jason Fung calls type 2 diabetes a problem of too much sugar stored in the body, Peter Attia describes the factors behind it and cases of remission, and Casey Means explains the early blood markers. They agree the condition can often be pushed back with food timing, weight loss and movement, which changes how patients should think about a diagnosis.
Is fruit a problem? Fructose, fiber and the fatty liver question
Robert Lustig and the Means siblings single out fructose as uniquely harmful to the liver, yet Jason Fung, Peter Attia and David Sinclair each draw a different line between whole fruit, juice and added sugar. Sorting out their positions tells readers what to cut and what to keep eating.
Use it or lose it: novelty and mental challenge protect the aging brain
Tommy Wood, Mark D'Esposito, Alan Castel and Charan Ranganath all say the brain stays adaptable when it keeps meeting new and demanding tasks, and that routine alone lets it slide. This gives people a second lever against cognitive decline that works alongside exercise and sleep.
Artificial Sweeteners: Harmless Swap or Hidden Problem for Gut and Appetite?
Layne Norton treats non-sugar sweeteners as a useful way to cut calories, Robert Lustig and Justin Sonnenburg see risks to insulin and the microbiome, and Peter Attia and Andrew Huberman end up in the middle with limited use. The sources show what evidence each position leans on; gastroenterologist Chris Thompson was asked the question, but his answer did not survive in the available transcript.
Change the body to change the mind: why thinking alone isn't enough
Huberman argues that brain and body form one loop, so breathing, movement and gut signals can shift mood and focus when thoughts can't. It explains why bottom-up tools often work faster than trying to reason your way out of a state.
Guard your working memory: fewer tasks, ramp-up time, no multitasking
Episodes on working memory, task switching, the prefrontal cortex and goal setting agree that attention is a narrow bottleneck: switching costs minutes of ramp-up and juggling goals degrades performance. Limiting daily priorities and building transition periods protects the brain's most valuable resource.
Is the mind more than the brain? Leaf, Sapolsky and Strassman disagree
Caroline Leaf argues the mind is distinct from and can change the brain, Sapolsky argues behavior is fully determined with no free will, and Strassman and Peterson leave room for the spiritual. The disagreement shapes how each thinks about responsibility, healing and change.
Mindfulness in the clinic: pain, trauma and wandering minds
A Stanford pain chief, a trauma psychiatrist using school mindfulness and Huberman's meditation episode all apply mindfulness to specific clinical problems, and advise choosing a practice that counters your own attention bias. It moves meditation from vague wellness to targeted tool.
Rehearse in your head: visualization, foreshadowing failure and alter egos
Huberman's visualization protocol, his goal-setting research and Chase Hughes's work with fighters show mental rehearsal can improve real performance, especially when it includes obstacles and failure. It works best as a supplement to practice, not a replacement.
Super stimuli: why processed food, porn and apps overpower reward circuits
Peterson, Malenka and Huberman describe how hyper-palatable food, pornography, social media and intermittent rewards deliver more reward than the brain evolved for, driving wanting beyond liking. Seeing them as super stimuli explains why willpower alone struggles and why changing the environment works better.
Deliberate over reflexive: strengthening top-down control of impulses
Several episodes frame self-control as the forebrain overriding reflexive limbic drives, from limbic friction to leaning forward into deliberate action, while Peterson argues for integrating drives rather than suppressing them. It gives a shared model for procrastination, anger and addiction.
Exercise is brain medicine: BDNF, energy and faster thinking
Huberman, Terry Sejnowski and neurologist Mark D'Esposito describe movement raising alertness, releasing growth factors like BDNF and supporting cognitive speed and healthy aging. It makes regular training one of the most direct, evidence-backed tools for thinking clearly for decades.
How to read a brain study: causality, reproducibility and hype
Peter Attia's journal clubs on epidemiology and statistics, Mark Gordon on research fraud, and placebo research on where effects stop all teach readers to question associations and small studies. It helps people judge health claims instead of chasing each headline.
Psychedelics and ketamine as plasticity openers, not magic cures
Ketamine, psilocybin and MDMA work through different receptors, yet the sources describe each as opening a temporary window of neuroplasticity that therapy and practice must then use. It explains why effects fade without integration and why a neurosurgeon calls drugs, not electrodes, today's best plasticity tool.
Reward the effort, not the result: teaching dopamine to love hard work
Several episodes converge on one protocol: praise and reward yourself for the effort and friction of a task rather than the outcome, so dopamine attaches to the work itself. Rewarding only results trains the brain to find the work unpleasant, while effort-based rewards make persistence self-sustaining.
Short stress sharpens you, chronic stress wears you down
Huberman, Sapolsky and Carrión separate acute stress, which mobilizes immunity, focus and performance, from prolonged stress that damages the hippocampus and weakens the prefrontal brake. Knowing where the line falls helps people stop fearing every stress response while taking chronic stress seriously.
