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.

The UC Davis Office of Research this week (July 10) announced the launch of the Microbiome Special Research Program (SRP), designed to leverage and build upon the broad and deep expertise in microbiome science across the university.
“UC Davis has incredible breadth and depth in microbiome research with over 100 laboratories actively pursuing projects with links to agriculture, environment, energy and human and animal health,” said Cameron Carter, interim vice chancellor for research at UC Davis. “The decision to invest in a platform to empower these teams was obvious given our strength in these areas and our potential to charter new frontiers that address some of our world’s most pressing issues.”

Soil Actually Has a Microbiome
Gut bacteria have been getting a lot of attention lately (yogurt, anyone?) but it turns out the soil in your own back yard is teeming with microbial life. According to Kate Scow, a professor of soil science and microbial ecology at UC Davis, a quarter teaspoon of soil can easily contain a billion bacterial cells. And she estimates there can be 10,000 to 50,000 different taxa of microbes in a single teaspoon. Soil is one of the most complex and diverse ecosystems on the planet, and it is one that is essential for human life through all the functions it provides: the breakdown of organic materials, food production, water purification, greenhouse gas reduction, and pollution cleanup, just to name a few.

A UC Davis-led study of nursing mothers in The Gambia shows how environment changes breast milk content
In a newly published study, UC Davis researchers and their colleagues, paint the picture of an elegant web of cause-and-effect that connects climate, the breast milk of nursing moms, gut microbes and the health of breast fed infants.
The research is part of a long-running. cross-disciplinary project at UC Davis studying milk and its role in nutrition. For example, last year UC Davis scientists and colleagues at Washington University St. Louis worked with both children and animal models to show how milk compounds could alter gut microbe composition and affect health. UC Davis researchers also led a consortium to study the “milk genome,” the collection of all genes related to producing milk.
