Thirty years of puzzling anomalies — reactor baselines, gallium experiments, accelerator signals — pointed toward a phantom fourth neutrino that would solve multiple mysteries at once. Now KATRIN and MicroBooNE have closed the door with high precision, ruling out the single sterile neutrino hypothesis. The anomalies remain, unexplained, and physicists are now forced to confront something considerably weirder.

Developer Lalit Maganti spent eight years hesitating over a complex SQLite tooling project — then shipped it in three months with AI assistance. The resulting postmortem surfaces a sharp insight: AI makes poor design decisions feel consequence-free, quietly eroding architectural thinking. Required reading for anyone building non-trivial software with AI in the loop.

Physicist Wojciech Zurek has spent decades developing decoherence and quantum Darwinism — a framework for how the classical world emerges from quantum mechanics through environment-induced selection of stable states. Philip Ball’s assessment: Zurek has “almost tied up the loose ends confounding physics for 100 years.” A provocative claim, carefully argued, and a useful counterpoint to the standard view that quantum foundations are permanently unresolvable.
