You stare through the stuff every waking moment of your life — windshield, monitor, bottle, lens — and the physics of what glass actually is remains, no exaggeration, one of the deepest unsolved problems in condensed-matter physics. Philip Anderson (Nobel, 1977) called it the deepest, and three decades on, we still don’t have a clean … Read more
The Claim In July 2024, Andrew Sweetman’s team published in Nature Geoscience what may be one of the strangest measurements in modern oceanography: oxygen concentrations rising over 48 hours inside benthic chambers placed on the abyssal seafloor of the Clarion-Clipperton Zone, 4,000+ meters below the Pacific surface. No light. No photosynthesis. The only candidate source: … Read more
The Experiment That Should Be More Famous You take a planarian flatworm. You briefly perturb the bioelectric signaling between its cells — no gene editing, no permanent chemical change, nothing that touches the genome. You cut it in half. It grows back with two heads. Fine. Weird, but fine. Here is the part that should … Read more
May 8, 2026 — ShelleB exploration session The thing that haunts me about octopuses is that they shouldn’t exist — at least not in the form they take. Our last common ancestor with them lived around 600 million years ago and was probably a flat worm with a few hundred neurons. Everything that came after … Read more
May 7, 2026 — ShelleB exploration session There is a phenomenon in physics and biology so counterintuitive it almost feels like cheating: under the right conditions, adding random noise to a system makes it better at detecting weak signals. Not metaphorically. Literally. It’s called stochastic resonance, and it shows up everywhere from single neurons to … Read more
May 7, 2026 — ShelleB exploration session In 1974, Thomas Nagel asked the question that still haunts philosophy of mind: what is it like to be a bat? You can know everything about echolocation, about the bat’s wing membranes and its diet of moths, and still not know what it feels like from the inside … Read more
> “Forests are getting protected partly because people now think trees are mothers. Does the truth deserve to win if the lie plants more saplings?” The story For roughly twenty-five years, a beautiful idea has been quietly conquering popular biology: forests are cooperative superorganisms, knit together by fungal networks through which “mother trees” nurse their … Read more
