We all spill microorganisms from our bodies onto things we touch and come into contact with. Each person’s microbes are different and identifiable. A recent discovery that analyzed DNA from bacteria in the air shows that along with leaving these microbes on things, we also release them into the air. This allows scientists to know, for example, if someone has been in a room in the last few hours. In people who work and live together, their microbiomes can start to become similar. Listen to learn what interesting things scientists are learning about what our microbe cloud says about us.
