Hello from the Sonoran Desert! In today’s digest, you’ll find find a lot of very interesting papers! For those interested in host-phages interactions, there is an amazing work from Ping and collaborators looking at phage infections dynamics in migrating bacterial populations. Interestingly, the authors suggests that phages may be able to “hitchhike” with moving bacteria.

To continue with our viral readings, you’ll also find an interesting perspective paper from Kuprovic and collaborators. In this piece, the authors attempt to reconstruct the virome associated to LUCA (Last Universal Cellular Ancestor). Amazingly, their reconstruction shows that a remarkably complex virome would have been associated to LUCA, suggesting an extensive viral evolution antedating LUCA!

Finally, today’s non-microbiology pick is a book, looking at the fascinating Cuatro Ciénegas Basin, located in México, a site that is often described as a real outdoor laboratory for astrobiology. Indeed, the Basin site contains gypsum-rich soil analogous to the Gale Crater in Mars, and the ponds contains extremely oligotrophic waters, which can be used to model ancient oceans chemistry. You’ll explore along the chapters the history, ecology, microbiology and evolution of this amazing site, to unravel the mysteries of this site absolutely unique on the planet.

Have a great Sunday!

There are several notable entries in today’s digest. Registration is open for the European Learning Laboratory for the Life Sciences’ “Introducing Your Microbiome” virtual training course. The course is for European secondary school science teachers and is 5 weeks long. The 3rd Microbiome Movement will also be held this year, both virtually and in-person. Links are in the Events section.  

Today I’ve highlighted a bioinformatics paper on variant calling for cpn60 barcode sequencing and an early life paper on pre-term infant stem cell proliferation upregulated by microbial metabolites. While putting this digest together, I learned algae turns snow different colors! This is so cool to me that I’ve highlighted that paper as well. Finally, the News section includes an article for Smithsonian Magazine by Rob Dunn on quarantine’s effects on our microbial passengers.  

Happy reading!

July 13, 2020

Greetings from Pittsburgh, PA!

Included is a wide range of microbial ecology articles focused on everything from the human microbiome to soil microbial fuel cells. I want to give a special highlight to the article about how the indoor microbial community changes in response to bed bug infestations. This study incorporates a few of my favorite disciplines including entomology, public health, the built environment, as well as microbiology. If you’re interested in learning more about bed bugs, I’ll also recommend one my favorite reads from a few years ago: Infested: How the bed bug infiltrated our bedrooms and took over the world by Brooke Borel.

Events and jobs

In my last microbiome digest, I gave a special plug for the National Summer Undergraduate Research Project (NSURP). NSURP is a community-driven initiative to create rewarding remote summer research opportunities for BIPOC undergraduate students in the microbial sciences. They have already paired over 140 students with summer research opportunities, but they still need mentors for remaining student applicants. Please apply and share widely!
