Insight | 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.

Insight | 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.

Insight | 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.

Insight | 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.

Insight | 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.

Insight | 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.

Insight | 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.

Insight | Beating hallucination: citations, verification and world models compared

Perplexity grounds answers in academic-style citations, Cursor looks to bug finding and formal verification, and Yann LeCun argues hallucinations come from LLMs' long tail and need world models to fix. Comparing these approaches shows readers how different builders try to make AI output trustworthy.

Insight | Can AI be conscious? Scaling optimists versus brains-aren't-computers skeptics

Anthropic's team takes the question of model experience seriously, Ted Gibson argues language is not thought, Pollan doubts brains work like computers, and Sean Carroll weighs simulations and AGI. The disagreement shapes how we should treat increasingly capable AI systems.

Insight | Consciousness may start in the body's feelings, not in abstract thought

Pollan, Mary Helen Immordino-Yang, Lisa Feldman Barrett and Allan Schore all root conscious experience in bodily feeling and regulation rather than in cortical reasoning. That shifts how we think about emotion, learning and what other creatures might experience.

Insight | Every brain is unique: early bonds, chance and development shape who we become

Allan Schore traces adult relationships to right-brain bonds in infancy, Immordino-Yang shows a toddler's feelings growing into ideas, and Linden highlights early experience and random developmental noise. It explains why people genuinely experience the world differently and why early relationships matter so much.

Insight | Hypnosis, meditation and prayer: trainable states with measurable brain changes

David Spiegel's hypnosis research, Andrew Newberg's brain scans of prayer and meditation, and Sam Harris's meditation practice all describe altered states that can be learned and that change brain activity. These practices offer drug-free ways to work with pain, stress and attention.

Insight | Letting go heals: why surrender keeps showing up in therapy, psychedelics and prayer

Nolan Williams, Matthew Johnson, Allan Schore and Andrew Newberg each point to surrender, not control, as the turning point in healing, whether in a psilocybin session, attachment-focused therapy or spiritual practice. It suggests that the ability to let go is a skill worth training, not a sign of weakness.

Insight | Microdosing disappoints: what the evidence and placebo research actually show

Robin Carhart-Harris and Matthew Johnson both weigh popular microdosing claims against trial evidence and the power of placebo, while Huberman's psilocybin episode explains how doses scale from mushrooms to milligrams. It helps readers separate a trend from what has been demonstrated.

Insight | Psychiatry's hardest problem: treating the mind when words are the only measure

Deisseroth notes psychiatry relies on words and found most treatments by accident, Williams describes a move toward circuit-based 'Psychiatry 3.0,' Barrett shows no one agrees what an emotion is, and Linden explores mind-body signaling. Together they explain why mental health care is hard and where it may be heading.

Insight | The body talks back: gut, heart and inflammation shape your mood

Zuker describes the gut-brain axis as a two-way highway, Williams maps a brain-heart circuit in depression, Linden links inflammation to depression, and Barrett explains mood through the body budget. Mental states are not just in the head, which opens new routes to feeling better.

Insight | The self is a construction: meditation, psychedelics and neuroscience reach the same conclusion

Sam Harris's meditation work, Michael Pollan's account of ego dissolution, Matthew Johnson's psilocybin trials and Karl Deisseroth's research on dissociation all describe the everyday sense of self as something the brain builds and can loosen. Seeing it this way reframes suffering, identity and why altered states can be so therapeutic.

Insight | The trip is not the treatment: integration decides whether psychedelic insights last

Carhart-Harris stresses integration, relapse and ongoing practice, Sam Harris calls psychedelics a doorway rather than a destination, and Huberman and Williams emphasize set, setting and medical care. Lasting change depends on what happens before and after a session, not just during it.

Insight | What is life? Assembly theory, information and the limits of definition

Sara Walker and Lee Cronin argue life is information structuring matter across time, while Adam Frank and Sean Carroll frame it through planetary processes and the emergence of complexity from entropy. How we define life determines how we'd recognize alien life and even mind.

Insight | Why we haven't found aliens: four thinkers, four very different answers

Adam Frank says there is no Fermi paradox, Sean Carroll explains why we don't see aliens, Elon Musk leans on the Great Filter, and Sara Walker proposes a great perceptual filter. Comparing them shows how assumptions about life and mind drive the whole debate.
