Life insurance for life: the survival case for expanding beyond Earth
Elon Musk calls becoming multiplanetary life insurance for life, Chris Mason argues from extinction awareness that humanity has a duty to survive and sets out a roadmap for engineering life to reach new worlds, and Robin Hanson weighs whether humanity should choose to expand into space given competition and global governance. Framing spaceflight as a question of survival rather than adventure changes how its costs and priorities are argued about.
Why reaching orbit is so hard: engines, staging and the push for reusability
Tim Dodd explains how rocket engines, propellants and engine cycles work, how engines are kept from melting, and the trade-offs of staging and the dream of single-stage-to-orbit, Elon Musk calls reusability the holy grail and explains why the Raptor engine is so hard to manufacture, and Neal Stephenson argues that chemical rockets are an accident of history. Seeing how much of the problem is engineering rather than ambition helps readers judge launch promises and timelines.
Why the secrecy? UFO disclosure advocates on what governments withhold
Jeremy Corbell and George Knapp explain why they think the secret was kept and what new disclosure law would do, James Fox asks why the secrecy persists and traces the road to the hearings, and Michael Shellenberger reports on a new UAP whistleblower. These are claims by advocates and journalists, and laying them side by side shows where their accounts line up and what remains unproven.
Finding meaning in a vast universe: what cosmic perspective gives scientists
Brian Cox calls Earth the only island of meaning we know, Ann Druyan describes science as the purest kind of love, Anna Frebel reflects on commitment and meaning, and Sara Seager writes of finding light after loss. Their accounts suggest that studying the cosmos can deepen a sense of purpose, which answers the worry that science makes life feel small.
Moon landing doubts and flat Earth: how science answers public distrust
Joe Rogan and Matt Walsh debate the moon landing, Brian Cox talks about social media and flat Earth, and Ann Druyan explains the role of science in a democratic society. Their exchanges show why distrust spreads and what kind of explanation scientists think can win people back.
Why conversations about the cosmos keep turning to artificial intelligence
Nathalie Cabrol links AI to what she calls humanity's teenage years, Michelle Thaller considers AI, meaning and life after work, Brian Cox asks whether a godlike intelligence would want anything, and David Kipping connects AI to the simulation argument. Scientists who study the universe keep arriving at the same question about our own future, and their long view is a useful frame for it.
Made of stars: how the universe forged the elements in your body
Michelle Thaller explains why we are made of stars, Anna Frebel traces heavy elements to the first stars and neutron star mergers, and Harry Cliff asks why matter survived at all. Their accounts connect everyday atoms to events billions of years old, one of the clearest ways to grasp our place in the cosmos.
Did the universe have a beginning? What physicists know about the earliest moments
Brian Cox asks whether the universe had a beginning, Michelle Thaller explains the cosmic afterglow and the Big Bang, Anna Frebel reads the first billion years in the oldest stars, and Harry Cliff asks why there is matter at all. Each approaches the early universe with different evidence, which shows readers what is measured and what is still open.
How life gets started: hydrothermal vents, panspermia and what counts as living
Nick Lane argues life began as chemistry in hydrothermal vents, Betül Kaçar discusses panspermia and rerunning the tape of life, and Nathalie Cabrol focuses on the nature of life and not just its origin. Their different starting points matter because the definition of life decides where and how we search for it.
The Great Silence: why intelligent life may be rare even if microbes are common
Brian Cox discusses the Great Silence and lonely civilizations, Nick Lane argues complex cells arose only once and the galaxy may be full of bacteria, Betül Kaçar points to life's one-time inventions, and David Kipping and Nathalie Cabrol weigh the Fermi paradox. Together they separate the question of life from the question of intelligence, which changes what we should expect to find.
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.
Connection is the long-term stress buffer
Huberman names social connection and delight as the key tools for long-term stress, Aditi Nerurkar highlights the loneliness epidemic and weak ties, Robert Waldinger describes relationships as a home base for refueling, and Kelly McGonigal counts relationships among our built-in resources. Other people regulate our nervous systems in ways solo techniques can't.
What chronic stress does to your body: belly fat, cravings, skin and immunity
Tara Swart links chronic stress to belly fat, Elissa Epel ties stress to cravings and cellular aging, Sara Szal and Gabor Maté connect stress and trauma to autoimmune disease, and dermatologist Teo Soleymani calls skin a stress biosensor. Chronic stress is a whole-body problem, which is why managing it pays off far beyond mood.
Meditation, hypnosis or NSDR? Choosing a calming practice
Huberman explains how to choose a meditation that runs against your attention bias and how NSDR differs from meditation, David Spiegel describes clinical hypnosis for stress and sleep, and Elissa Epel links meditation to telomeres and mitochondria. Several evidence-based practices exist, and fit with your temperament determines which one you'll actually keep.
Box breathing, cyclic sighing or Wim Hof? Choosing the right breathwork
Huberman compares the physiological sigh, cyclic sighing, box breathing and cyclic hyperventilation, Jack Feldman explains box breathing and why breathing and emotion are a two-way street, Dr. Chatterjee teaches the 3-4-5 breath, and Wim Hof-style breathing appears as training for stress. Different patterns push the nervous system in different directions, so the goal decides the technique.
