A heads up to anyone interested in what's living in your gut. I think it's safe to say that most of us here are pretty fascinated with all things gut, and here's a chance to participate in an open sourced research project to "characterize the microbial diversity of the American gut." It's a bit pricey, $99 for a DNA extraction, and yeah, you have to collect stool samples. You also have to give them a detailed diet log for at least three days, longer is even better. And they're particularly interested in people following specific diets, including gluten free, but also veg*n, paleo and any combination thereof. The results will be available some time next year. I've signed up, so I can share if anyone here would be interested.
