One Place Like Home: Space Station Has Same Microbes as Your House

By Carole Gan

UC Davis microbiologists have analyzed swabs taken by astronauts on the International Space Station – and found pretty much the same types of microbes as in a home on Earth, according to an analysis published today (Dec. 5) in the journal PeerJ.

The International Space Station is interesting to scientists studying the microbial ecology of buildings because it is a “building” with very few ways to bring microbes in or out.

Citizen science and Project MERCURRI

The work was part of Project MERCCURI, a collaboration between UC Davis and other organizations including Science Cheerleader, a group of current and former professional cheerleaders pursuing careers in science and math.
