* “The U.S. made a breakthrough battery discovery — then gave the technology to China.” Maybe we shouldn’t do that.

* “Skin exposure to UVB light induces a skin-brain-gonad axis and sexual behavior.” It’s in Cell and thus SFW.

* “Sensitivity Readers Are the New Literary Gatekeepers.” Which can’t be helping fiction sales: we used to make fun of the Soviets for insisting on doctrinaire art. Now, big publishers insist on it, which is particularly odd given the vitality of gatekeeper-free Internet writing.

* Has Technological Progress Stalled?

* A plan to tax the very large endowments of some universities.

* The national housing shortage is likely in the four to twenty million range.

* “Inside the War Between Trump and His Generals.” The first paragraphs are consistent with previous actions and yet still horrifying.

* “‘The Literary Mafia’ Review: People of the Book.” Jews, books, and ideas.

* An essay against Puritanism, though that’s not the title the author uses. It’s a rant.
