Good morning from Massachusetts! Dr. Elisabeth Bik will be giving a Zoom talk today on research misconduct in biomedical research. You can register at the link under events. Fittingly, today’s digest includes a preprint on the effects of retraction after misconduct on citations. Other highlights today include an entire theme issue on the microbiome and host evolution and a paper on phylogenomic analyses of archaea attempting to elucidate the DPANN lineage. In early life, the placental microbiome debate rages on with a paper demonstrating evidence for contamination rather than an actual placental microbiome. Finally, I have highlighted a paper studying whether soil archives can give us a glimpse into soil microbial communities of the past.

Have a great weekend!

July 19, 2020

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!
