Greetings from Pittsburgh!

Today’s digest is heavy on environmental microbiology work, especially plant, root, and soil microbiome studies. I also want to highlight a fun research paper (and paired Wired article) on the microbiome of da Vinci’s drawings.

Happy reading! And for all of those in the U.S. who are celebrating the Thanksgiving holiday, please be safe and follow all local COVID precautions.

Greetings, friends!

Today’s digest contains a wealth of microbiology articles focused on everything from the dog ear canal microbiome to estuarine methanogen communities. Rather than highlight a specific research article, today I’d like to encourage you to check out this week’s New York Times article profiling the organizers of Black in Micro Week and this commentary published by one of the organizers in mSphere. Black in Micro week began this Monday and programming is scheduled to continue through October 4th. If you missed earlier events, you’re in luck! The organizers have already uploaded videos of all completed events at the Black in Micro youtube channel.

Hello from Lübeck/Germany,
today we cover a broad range of microbiome related studies. Of particular interest is a preprint by the Korem lab about use of antibiotics and increase in aggressive behavior in D. melanogaster. This study got already some attention on Twitter and in the press. Furthermore, one preprint covers the C. difficile species problem, investigating the genetic heterogeneity of this species. Last but not least, I would like to mention a paper investigating responses of megakaryocytes, erythroid cells and plasmablasts as hallmarks of severe COVID-19 trajectories.

God morgon!

Good morning from Sweden. It’s Monday, beginning of a new week and today’s digest carries a lot of preprints with interesting information.

As ususal, new knowledge about COVID-19 keeps pouring in. A library of 1200 small molecules was screened to reveal at least 20 FDA-approved small molecules that can enhance the antiviral activity of remdesivir. A human enzyme was also shown to be involved in antiviral defences. A new preprint also revealed some modifications in the SARS-CoV-2 spike protein that can increase vaccine efficacy.

Continuing with viruses, new preprint report an improved Zika vaccine, a basic study exploring reverse transcription and thereby developing a better system to study anti-HIV drugs, and a new detailed protocol for enriching viromes in water samples.

Also in today’s digest are some preprints on basic bacteriology with reports on (p)ppGpp and persister cells, Streptococcal membranes, secretory products and their role in Listeria virulence, and efflux pumps in Burkholderia.

Apart from these, there are, coincidentally, two reports on microbial diversity of the waters of Shark Bay, Australia, algal diversity in corals, a relationship between termite gut-microbiota and changes in temperature, and the role of gut microbiota in possibly affecting the sexual dimorphism in susceptibility to diseases.

Hope you enjoy the collection!

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!

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!
