Our collaboration with U. Pennsylvania and Stanford just came out this week in PNAS! We showed we could manipulate the bacteria in flies evolving in outdoor environments, and the manipulations confirmed that variation in the microbiota changes the genetics of the host. Co-authors Rachel Hughes, Dallin Lowder, and Skyler Lemmon (undergraduates in the lab) were instrumental in manipulating and measuring the microbiota changes and effects. Check out their great work!

Congratulations, and on to the good work!
