The bizarre illustration was embellished with nonsense labels, including one fortuitously designated as “dck.” The article on rat testes stem cells had undergone peer review and editorial vetting before being published in February by Frontiers in Cell and Developmental Biology.

“Mayday,” blared longtime AI researcher and critic Gary Marcus on X (formerly known as Twitter). Vexed by AI’s ability to abet the “exponential enshittification of science,” he added, “the sudden pollution of science with LLM-generated content, known to yield plausible-sounding but sometimes difficult to detect errors (‘hallucinations’) is serious, and its impact will be lasting.”

DEATH BY LIGHTNING

Mike Makowsky opens Death by Lightning, a four-part miniseries he wrote and produced, with a chilling line: “This is a true story about two men the world forgot.
