Yogurt bacteria could replace colonoscopies for cancer detection

working on engineered bacteria that detects colorectal cancer. After the nanoparticles pass through the digestive system, a urine sample shows results on a reactive paper -- similar to that of a pregnancy test. In addition to being much less invasive, the high-powered yogurt method doesn't require a lab full of equipment, making it an attractive alternative for poor locales. Here's to hoping scientists figure out a better way to get through a root canal next. http://www.engadget.com/2014/10/03/cancer-finding-yogurt/
