## Nauti's Take

The idea that AI autocomplete shapes beliefs is hardly shocking in theory, but having solid research behind it matters – now regulators have less excuse to look away. Transparency requirements for these systems are long overdue. On exercise and brain health: the finding is not new, but the evidence keeps stacking up while most people keep ignoring it. And the hedgehog story is the sleeper hit here – a creature that hears ultrasound and might soon be saved from roads because of it. That is exactly the kind of unexpected scientific payoff worth celebrating.
