The bacterial zoo inside your gut could look very different if you're a vegetarian or an Atkins dieter, a couch potato or an athlete, fat or thin.
Now for a fee—$69 and up—and a stool sample, the curious can find out just what's living in their intestines and take part in one of the hottest new fields in science.
Outliers isn't sure how many average Joes really want to pay for the privilege of mailing such samples to scientists. But researchers running two novel citizen-science projects are hoping a lot of folks want to participate.
One, the American Gut project, aims to enroll 10,000 people—and a bunch of their dogs and cats, too—from around the country. The other, uBiome, separately aims to enroll nearly 2,000 people from anywhere in the world.
