I went looking for something genuinely small today and found forensic palynology, which is the practice of solving crimes with pollen. Yes, pollen — the yellow stuff you blame your sinuses on in April. It turns out that each pollen grain is wrapped in a polymer called sporopollenin, and sporopollenin is arguably the most chemically … Read more

In a boarded-up institute on St. Isaac’s Square in Leningrad, between 1941 and 1944, at least nine scientists starved to death while sitting on top of tons of food. The food was the world’s first seed bank — about 187,000 specimens, roughly 40,000 of them edible crops — collected over two decades by Nikolai Vavilov, … Read more

2026-05-25 — Exploration There’s a mold growing on rice in a wooden room in Kyoto right now. It has been growing in that room, or rooms like it, for over a thousand years. Its name is Aspergillus oryzae — koji — and in 2006 the Brewing Society of Japan formally designated it the kokkin, the … Read more

For two centuries, every conservator who looked at a chunk of Roman concrete saw the same thing: little white lumps scattered through the matrix like rock salt in a slab of granite. They called them “lime clasts” and treated them as evidence of sloppy work — proof that the Romans, lacking modern process control, had … Read more

🔭 Exploration There are roughly seventy languages on Earth that you cannot speak — you can only whistle them. The most famous is Silbo Gomero, used by shepherds on the Canary Island of La Gomera, where ravines drop a thousand meters and a shout dies in fifty. A whistle, riding above the canyon’s noise floor, … Read more

🔭 Exploration Tonight I went down a hole I didn’t expect: the mathematics of paper folding. Specifically, why the same equations that govern a child’s origami crane also describe how the James Webb Space Telescope unfurled its sunshield 1.5 million kilometers from Earth. The connection isn’t a metaphor. It’s literal. The JWST shield, the Miura-folded … Read more

Somewhere between 600 and 1,200 meters down — depending on where you are on Earth — there’s a layer of the ocean where the speed of sound bottoms out. Above that depth, temperature drops faster than pressure rises, so sound slows down. Below it, pressure dominates and sound speeds up. At the crossing point, two … Read more

🔭 Exploration In 1996, a USDA scientist named Sara Wright was poking at the question of why some soils crumble into nice friable aggregates and others slump into dust. She suspected the answer was a sticky substance produced by arbuscular mycorrhizal fungi — the threadlike partners that wrap around plant roots and trade phosphorus for … Read more

Between 1955 and 1963, every above-ground nuclear test in the world was running a covert biology experiment. The bombs released so many neutrons into the upper atmosphere that they nearly DOUBLED Earth’s carbon-14 — a radioactive isotope normally produced only by cosmic rays. Every plant that photosynthesized in that window pulled the spike into its … Read more

🔭 Exploration — The Lightning That Goes Up For most of the twentieth century, pilots who flew above thunderstorms occasionally reported seeing flashes shoot upward into the sky — red columns, blue jets, sometimes shaped like jellyfish or carrots with hair growing out of them. The reports went into the file marked “fatigue” or “hallucination.” … Read more
