Greetings from Pittsburgh, PA!

Today’s digest a contains articles focused on the oral microbiome, koala symbionts, soil microbial communities, and more. For those of you who are a bit too tired to digest cutting-edge research, I suggest using the 10 simple steps outlined in the highlighted editorial to colorize your own data visualizations. Finally, if you just need a break, I suggest bookmarking the article on the whale skin microbiome and revisiting the film Star Trek IV: The Voyage Home.

Happy reading (or movie watching)!

Good morning from sunny San Francisco, California! Today’s digest shares some fascinating in vivo studies including a paper from Ou et al. examining the role of host antimicrobial proteins α-definsins in bacterial colonization and epithelial cell adherence in the gut and a proof-of-concept paper from Hsu et al. in which the authors orally delivered an engineered phage to the gut of mice that was capable of specifically repressing gene expression in bacteria. Additionally, there are some great plant, root, and soil microbiome papers (Kusstatscher et al. show that treating maize seeds with a plant growth-promoting rhizobacteria improves plant health) and water microbiome papers (León-Zayas et al. published a super collaborative paper looking at microbiome sharing between sediments, seagrasses, and reef fish at multiple sites). Finally, I wanted to highlight a paper by Zelaya et al. outlining a course-based undergraduate research experience for teaching microbiology that focuses on the bean beetle microbiome.

Hello from the Sonoran Desert! In today’s digest, you’ll find quite a few exciting reads about ancient microbes!

Duchêne and collaborators review recents efforts in paleopathology leading to the genome sequencing of ancient pathogens of historical interest such as the pre-modern bubonic plague (Yersinia pestis), smallpox (Variola virus) and cholera (Vibrio cholerae). In their review, the authors explore this amazing topic that aims to broaden our understanding of the past infectious disease.

On the other hand, Eisenhofer and collaborators examine ancient microbial DNA preserved within dental calculus samples from two major cultural periods in Japan: the Jomon period circa 3000 years ago and the Edo period circa 400–150 ago. In this piece, they explore how human oral microbiomes have changed through time in ancient Japanese populations.

Finally, you’ll find in this digest a non-microbiology pick: a “10 simple rules” paper outlining best practices for annotating and submitting sequencing data! Indeed, metadata accompanying sequence datasets is critical to ensure data longevity and reusability by both human and machine agents, and poor metadata can drastically reduce the value of sequencing experiments by limiting its reuse in integrative analyses!

Have a great Sunday!
