New robot vacuums announced at CES 2026Several top robot vacuum brands unveiled new flagship models at CES in early January. These include the Roborock Saros 20 Sonic and Qrevo Curv 2 Flow, the Dreame X60 Max Ultra Complete, and the Narwal Flow 2. I'm in the process of testing these at home and will update this guide accordingly as each are officially released to the public.
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.
