The footage is seen amid a compilation of images of U.S. warfare posted to the official White House X account. The clip begins with gameplay from Call of Duty: Modern Warfare III, a scene depicting a kill streak animation in which a user unlocks the ability to launch a nuclear arsenal. The video is accompanied by the text "Courtesy of the Red, White & Blue."
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.
