Greetings for the month of September: the Haervest-monath (Harvest Month). Today’s microbiome digest consists of a cool editorial article on hidden theatre of microbes. The digest also features two interesting reviews; first one detailing the role of skin microbiota in forensic sciences and the second one with focus on association of sponges and their microbiome.

Let’s celebrate the month of September with some fascinating microbiome studies.

There are flowers enough in the summertime,
More flowers than I can remember—
But none with the purple, gold, and red
That dye the flowers of September!

Hello from the Sonoran Desert! In today’s digest, you’ll find quite a few exciting papers! For those interested in soil microbiology, you’ll find in today’s digest a very interesting piece on the the biodiversity and ecology of protists in the soils of the McMurdo Dry Valleys (Antarctica). This piece is particularly exciting given that the role and impact of protists in polar regions is largely unknown and understudied.

Curious readers should also take a look at the amazing study by Dunaj and collaborators focusing on spider’s associated microbiome. This piece examines the host-microbe co-evolution of different widow spider species showing a strong congruence of the microbiome beta-diversity and the host phylogeny.

Finally, in today’s non-microbiology pick, I recommend a preprint, that explored the relationship between the use of jargon and citations in cave research articles. Interestingly the authors suggest that the juse of jargon in title and abstract significantly reduces the number of citations a paper recieves!

Have a great Sunday!

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!

Greetings Everyone. Today’s Microbiome Digest comprises of a wide variety of topics covering soil microbiota, tumor to water to extremophile microbiome. The digest has some reviews, books, as well as interesting articles on how synthetic microbial communities facilitate sustainable growth and the role of microbial communities in balancing the environment. A terrific news article covering the isolation of microbes buried beneath the sea floor for more than 100 million years. Today’s digest can be summarized by a quote by Julie Morley.

“Every being devotes and dedicates itself to some innate purpose. Single cells, microbes, plants, insects, animals – every being makes it own unique contribution” – Julie J. Morley
