Your skin is covered in living things. There are bacteria in your armpits causing a stinky odor. There are ancient archaea that like to eat your sweat. And a common bacterium helps to keep your skin healthy — or makes you break out.
Inside you, there’s even more of these tiny living things. They make up your microbiome. And they can influence your health, behavior and more.
When scientists study these bacteria, archaea and fungi in the lab, they often look at one species at a time. They may not even be able to grow some species in the lab environment. These critters, though, often live in complex communities. That can make studying individual species more difficult. But what we learn could lead to important knowledge about our environment and ourselves.
