This was not the first time that microbiologists experienced problems with agar. A phenomenon called “The Great Plate Count Anomaly” baffled researchers in the early 20th century when they observed that the number of cells seen under a microscope didn’t match the actual number of colonies growing on an agar plate. Investigating this discrepancy, researchers found agar itself to be the culprit: when nutrient broths are heated with agar during boiling, harmful byproducts (hydroperoxide) can form due to the reaction of agar with phosphate minerals contained in the media. Researchers can avoid this by autoclaving agar separately from the nutrient broth, or by reducing the amount of agar used.

A news site publishing an AI-written review is just as dire as Metacritic aggregating it, and that appears to be what VideoGamer is doing. ClickOut Media, the company that owns VideoGamer and a collection of other publications, reportedly laid off the staff of its gaming sites earlier this month to pivot to AI-generated content. Sifting through AI slop, whether on social media or Pinterest, is increasingly necessary online. Now apparently Metacritic is another place where readers should have their guard up.
Singh’s New Yorker article ends by asking what these sorts of searches for common origins tell us: “that our wild, warring species shares something irreducible at its core.”。91视频对此有专业解读
