Why three AI builders say open models are safer than closed ones

Mark Zuckerberg makes the case for releasing Llama and for many AIs instead of one, George Hotz argues that open source is itself AI safety, and Yann LeCun says open source is the answer to bias and to fears of AI doom. Their shared argument runs against the common assumption that powerful AI is safest when kept locked up, so it is worth seeing how each one reasons.

Deliberate cold as stress training: the 11-minute weekly dose

Susanna Søberg's research sets a minimum of about 11 minutes of cold per week and advises ending on cold, Huberman explains how cold builds resilience and dopamine, Ralph Adolphs discusses ice baths as regulation practice, and Huberman frames cold and breathwork as training for bad weather. Choosing a controlled stressor teaches the nervous system to stay calm under uncontrolled ones.

Trauma lives in the body, so healing has to include it

Gabor Maté explains how unresolved trauma lives in the body, Nicole LePera says trauma stored in the body shapes belief, Mel Robbins' therapist teaches a somatic 'slithering' practice for morning dread, and Paul Conti describes processing trauma rather than avoiding it. Talking alone often isn't enough when stress is held physically.

Name it to tame it: emotional granularity as a stress tool

Susan David treats emotions as data and teaches precise labeling, Huberman's mental health toolkit highlights emotional granularity, Julie Smith treats emotions as information, and Ralph Adolphs describes monitoring emotions as the first step in regulating them. Precise labels give the thinking brain a handle on a stress response.

Are chatbots minds? Three scientists weigh in on large language models

Carroll says language models exploit our bias to see intentions in humanlike things, Walker sees them as a genetic system for language and rejects AI doom stories, and Frank doubts current models have real agency. Coming from physicists thinking about life and mind, these views offer a grounded counterweight to AI hype and fear.

Are we alone? Four scientists split on how common alien life is

Adam Frank argues there is no Fermi paradox and that we are probably not the first civilization, while Brian Keating and Sean Carroll suspect the silence means life, or at least civilizations, is rare, and Sara Walker wonders whether advanced life could even perceive other advanced life. Seeing the same evidence read four ways shows how much of the alien question still rests on assumptions rather than data.

Free will survives physics, three scientists argue for different reasons

Carroll says free will is as real as tables and chairs, Walker says it comes from being a deterministic structure with enough history in a random environment, and Frank says it is simply a given that science must account for. The agreement matters because it rejects the common claim that physics has disproved free will.

Ideas are cheap, measurements are king: how physicists guard against wishful thinking

Across these conversations scientists keep choosing data over beautiful ideas: Lincoln loves string theory but doesn't believe it, Keating watched his BICEP signal turn out to be dust, Carroll bets his own team's hoped-for signal will go away, and Frank says a cool topic doesn't get a pass. It shows why science earns trust by being willing to be proven wrong.

Life, not particles, may be physics' next great frontier

Sara Walker says new physics lies in the problems of life and intelligence rather than high-energy physics, Sean Carroll has shifted from guessing new laws to studying how complexity emerges, and Adam Frank calls the question of what life is the biggest question in physics. Three researchers independently pointing to the same frontier suggests where the next big breakthroughs may come from.

Many worlds on trial: one champion and two skeptics

Sean Carroll defends the many-worlds interpretation as simply taking the Schrödinger equation seriously, while Sara Walker says she is not a many-worlds person and Adam Frank argues it invents infinite unobservable universes, preferring QBism. The disagreement shows that the meaning of quantum mechanics is still wide open among working scientists.

Physicalists and critics clash over where consciousness fits in physics

Sean Carroll treats consciousness as a real way of describing physical processes and rejects panpsychism, Sara Walker ties experience to our being extended in time, and Adam Frank argues science has a blind spot that erases lived experience. The split shows that even physicists who agree on the equations disagree on how minds belong in the picture.

Stop waiting for a radio call: smarter ways to find aliens

Carroll argues listening for radio signals is a poor strategy and a quiet alien probe is more likely, Frank prefers passive technosignatures like industrial pollution, city lights and ancient lunar artifacts, and Walker predicts first contact may come in an origin-of-life experiment. Together they sketch a search that looks for evidence of activity rather than a deliberate hello.

The universe is not a computer, say three scientists

Carroll sees no reason to take the simulation hypothesis seriously and says cellular automata don't match real physics, Walker argues computation sits at the top of reality rather than its base, and Frank points to arguments that living systems cannot be fully captured by algorithms. It pushes back on a fashionable idea that reality is fundamentally code.

The universe's first moments are still a mystery

Keating says the Big Bang's cause is unknown and inflation is only the leading idea, Carroll is maximally uncertain whether time had a first moment, and Lincoln says no one knows why matter beat antimatter. Their candor shows how much of cosmic origins remains open despite confident headlines.

Why a theory of everything may be centuries away, or impossible

Don Lincoln thinks the needed energies are a quadrillion times beyond today's colliders, Sara Walker doubts reality has a ground or a theory of everything at all, and Adam Frank notes string theory has had decades of effort without a breakthrough. It tempers popular expectations that a final theory is just around the corner.

Match the stress tool to the timescale: seconds, weeks and years

Huberman sorts tools for acute, medium-term and chronic stress, Elissa Epel groups stress tools into mind, body and environment buckets, and Robert Sapolsky warns that easy recipes fail and advises picking your own practice and doing it daily. Using a breathing tool for a chronic problem, or a lifestyle change for a panic moment, explains why many stress strategies disappoint.

Self-medicating stress with alcohol and cannabis backfires

Huberman explains that regular drinking rewires habits and raises baseline stress, Matthew Hill describes cannabis use disorder and potent concentrates, Gabor Maté asks what pain an addiction is soothing, and Elissa Epel shows how stress hijacks cravings. Substances that relieve stress in the moment tend to amplify it over time.

Pain is shaped by stress, attention and love

Sean Mackey explains that pain happens in the brain and is shaped by stress, memory and love, Huberman describes the pain-buffering power of love and hypnosis, and Ellen Langer shows how perception shapes healing. Because stress amplifies pain, calming the nervous system is part of pain treatment.

Avoidance feeds fear: why exposure and a new story heal trauma

Huberman explains that fears are undone by extinction plus a new narrative, his OCD episode shows compulsions feeding obsessions while exposure therapy works, Victor Carrión says avoidance feeds PTSD, and the dreams episode explains how REM and EMDR quiet the amygdala. Facing the feared cue in a safe way, then rewriting its meaning, is the common core of effective fear treatment.
