Let's face it: colonoscopies are pretty unpleasant. But what if you could eat a spoonful of yogurt to check for cancer rather than enduring that procedure? MIT professor Sangeeta Bhatia is 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.
