Came upon this interview just this morning and although the research discussed was done in a university office building and a hospital, the implications for residential buildings are apparent.
The more we learn, the more we realize we don't know...what an exciting time to be alive!
Here's the first paragraph:
"While some scientists spend their lives studying the rainforest or the ocean, Jessica Green considers ecosystems closer to home: offices, classrooms and even bathrooms. A biodiversity scientist and director of the Biology and the Built Environment Center at the University of Oregon, Green’s work aims to understand the role of these microbial ecosystems on human health."
