Happy Monday morning from San Francisco, California! Hope everyone had a restful weekend. For those who aren’t quite ready for the working week, how about easing in to things with a warm beverage and some great microbiome reads?

Today’s digest includes two papers that blew my mind. The first is a paper by van Tatenhove-Pel et al. which looks at how cell-to-cell distance in 3D space impacts the metabolic interactions between bacteria. The second, by Nowosad et al., examines the role of the gut microbiota on B cell selection and antibody affinity maturation in gut-associated germinal centers. Other fascinating papers include: a pilot study profiling the gut microbiomes of South Africans in an urban cohort and a transitioning rural cohort which was designed collaboratively with community leaders (Oduaran et al.); a review paper about using brachyuran crabs as a model for studying how animal-microbiome symbioses evolve when aquatic organisms transition to land (Cannicci et al.); and a paper that used shotgun metagenomics to identify current and historical microbiomes in lake sediment which could help our understanding of how humans impact lake ecosystems over time (Garner et al.). Happy reading, y’all!
