What's up in
Mind & Meaning
The psychology of ambition, isolation, and meaning under extremes — and what frontier life teaches us about being human.
Most of the matter in the universe has never been observed directly, and the existence of "dark matter" is essentially a placeholder name for the gap between what we can see and what the math requires — a placeholder we've been using confidently for about ninety years
Most of what we call "memory" isn't a recording of what happened — it's a reconstruction that gets edited slightly every time it's retrieved — meaning the more you remember something, the further it drifts from what actually occurred, and the most vivid memories of your life are often the least accurate
There's a real, measurable cognitive trait called "intellectual humility" that turns out to predict accuracy on almost every kind of judgment task — and the people who score highest on it aren't the ones who know the most, they're the ones who hold their existing beliefs slightly more loosely than everyone around them
The single oldest non-clonal living thing on Earth is a bristlecone pine called Methuselah, growing on a windswept slope in California's White Mountains at 9,800 feet — it germinated around 2833 BCE, which means it was already a thousand years old when the Egyptians were finishing the Pyramids, and the U.S. Forest Service refuses to disclose its exact location for fear of what tourists would do to it
Most professional mathematicians, when describing the moment a difficult proof finally falls into place, use language closer to discovery than to invention — and the consistency of that framing across cultures and centuries has driven philosophers of mathematics to a serious unresolved question about whether mathematical structures exist independently of the minds that find them
AI can now read your emotional state in a shop, adapt what it shows you in real time, and increase sales by double digits — and most shoppers have no idea this is already happening
Indigenous Amazonian shamans identified the specific combination of two plants required to make ayahuasca active orally — a pairing that stands as what may be one of the most unlikely discoveries in the history of human botany, given there are roughly 80,000 plant species in the Amazon
Women's sense of smell is roughly 50% more sensitive than men's on average, and the gap widens during pregnancy to a degree that some evolutionary biologists think is a defence mechanism for the fetus
The clearest indicator of whether a person has aged well into their seventies is not health, wealth, or relationships. It is whether they have continued to be surprised by things.
Female brains have measurably more connections between the two hemispheres, and male brains have more connections within each hemisphere — and neuroscientists still argue about whether this explains anything or nothing at all
