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!

Greetings Everyone,
I want to began the month of July on a note that diversity is the basis for life. I can’t think of anything better to teach us about diversity, co-existence, and evolution than the fascinating Microbiome.
The microbiome affects us right from our birth till the end affecting our mental as well as physical health. The microbiome exhibits all sorts of differences in shape, size, color, metabolic functions in order to sustain life.
Much to learn from these tiny beings!!!!
Today’s Digest comprises of some interesting studies about effect of microbiome on chemotherapy and studies on tumor microbiome. It also includes articles exploring genetics of gut microbiome and the role of microbiome in inflammatory bowel disease. Additionally has a news article about taking microbiome therapies to clinical trials.
Hope you enjoy reading today’s digest!!

Greetings from Pittsburgh!

Today’s digest is unintentionally themed around change. Included is an article on the metabolic versatility of Salmonella enterica and another on the genetic diversification of Escherichia coli. If you’re more interested in the big picture, there is also an article about the evolution of ecological niches in plant-associated microbes as well as an article about the impacts of global change on soil microbial diversity and functionality.

Here’s to hoping that we are just as resilient as the microbes we study!

Events and jobs

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.
