Scientists use lasers to sniff out E. coli on food
Scientists have developed a better sniff test for that plate of leftovers that's been hanging out in your fridge. Researchers from the Korea Advanced Institutes of Science and Technology are using lasers (the jury is out on whether they're of the "friggin'" variety or not) to determine just how much bacteria is crawling all over your stored food. MIT Technology Review says that by shooting a red, coherent laser at chicken breast coated with E. coli and Bacillus cereus, the Korean scientists were able to detect changes in laser refractions, indicating the bacteria's presence.
