Injecting plant-like creatures into a rat's heart can jumpstart the recovery process, study finds

When it comes to a crowdsourcing campaign, food might be an easier sell than feces. “Food is this amazing platform because we all have a connection to it, we all can relate,” says microbiologist Rachel Dutton. Not that poop isn't relatable, but, you know.

You Are What You Eat, And What You Eat Is Millions of Microbes

Now that they’ve tallied up American feces, researchers are turning to the other half of the microbial equation: food
