Fire the lasers and protect against foodborne illnesses with the help of a handful of scientists. Researchers at the Korea Advanced Institutes of Science and Technology have developed a device that can be mounted inside refrigerators and uses a laser to scan foods for microbes, according to Ars Technica.
The technology uses a camera to monitor patterns as a laser fires repeatedly at the surfaces of foods in the fridge. Certain bacteria, like salmonella, have hair-like extensions called flagella that they use to move around the surface of food, and the laser and camera pick up these…
