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.
Senate Democratic leader Chuck Schumer of New York said his caucus in the coming days would also review unredacted versions of the Epstein case files at a Department of Justice office. Schumer, who demanded that the department release all of the files and preserve all materials, said they will “pull on every thread” until they “reveal this massive cover-up.”
