In last week’s episode, we traced the history of fluoridation (and the anti-fluoridation movement) to its roots in the early 20th century, but we left you wondering whether there’s anything to back up the health claims that anti-fluoridationists make. Today, we get deep into the weeds of the fluoride literature, explaining how this mineral works, the difference between topical and systemic fluoride, and whether fluoridation has been linked to any health issues. The details matter, and don’t you worry - we’ve got plenty of nitty gritty for you to feast on. Support this podcast by ...

The universe is a vast, mysterious, and incredibly cool place. It’s filled with things so strange and wonderful they can make your head spin.

It wasn’t just hype—it was a sweeping new vision: an AI-powered world where agents don’t just answer—they act....

Rivers, on a long view, are alive. They are born; they change; they shift their channels; they forge new routes to the sea; they move both gradually and violently; they can teem (usually) with life; they may die a quasi-natural death; they are frequently maimed and even murdered. It is the annual flood pulse—the brief time when the river occupies the floodplain—that gives a river its vitality, but it is human engineering that kills it, suppressing the flood pulse with dams, irrigation, siltation, dikes, and levees.

Passengers get bumped from flights. Phone menus disconnect. Automated financial trades produce market collapse. Of all the challenges in modern life, some of the most vexing come from our relationships with automation: a large system does us wrong, and there’s nothing we can do about it. The problem, economist Dan Davies shows, is accountability sinks: systems in which decisions are delegated to a complex rule book or set of standard procedures, making it impossible to identify the source of mistakes when they happen.
