Researchers have created glow-in-the-dark plants by injecting succulents with materials similar to those that make the posters light up.

wired.com David Gilbert 2025-10-19 21:28:04

Minutes after the perpetrator of the shooting at Annunciation Catholic Church in Minneapolis last week was identified, YouTube appeared to delete several videos they had shared that morning. But not before the videos were downloaded and reshared in full on X. Within hours, the platform was flooded with wild claims about the shooter and her motivation, with everyone from Elon Musk, the site’s owner, to the head of the FBI and left-wing activists posting half-baked allegations blaming anti-Chris

Alphabet shares rose 9% on Wednesday as investors viewed the result of Google's antitrust case as broadly favorable to the tech giant. The U.S. Department of Justice had proposed a sort of break-up of Google, which included divesting its Chrome browser, in an antitrust case that began in September 2023.
