Greeting everyone from the boiling hell southern Spain tourns every Summer.

Today we have a lot of soil microbiome in general. Also PARGT, a new software tool for predicting antimicrobial resistance in bacteria. And new insight in the relatioship between blood type and bacteria.

Greetings from Wiltshire, England!

Today’s digest brings a little bit of everything. We’ve been cataloguing the latest COVID-19 publications during this pandemic, and today I’m please to bring you a paper combining both COVID-19 and microbiome research!

Elsewhere, there are plenty of environmental microbiome publications, including a great paper on the challenges of studying microbiology in space, an analysis of how aerosols spread COVID-19 and other infectious agents in dental practices, and plenty of articles on various aspects of soil microbiomes.

I hope everyone’s coping well during these times. On a personal level, I’m delighted to be returning to the lab this week to resume my PhD research into gut microbiomes and cancer. I’m glad to be back, but worried about how my pipetting skills have suffered during my time off!

Stay safe, and happy reading!

Happy Wednesday, y’all! Before we get to today’s papers, I wanted to let everyone know about a webinar happening on June 3rd at 12:00 PM E.T. called “Unraveling the link between the gut microbiome, human health, and disease.” Tomoya Yamashita, M.D., Ph.D. from Kobe University Graduate School of Medicine and Meredith Hullar, Ph.D. from the Fred Hutchinson Cancer Research Center will both be speaking. If you’re interested you can register here.

Now onto the highlights! We have some super interesting research to share with you today including an examination of the efficacy of transplanting the human gut microbiota into mice and its impact on studying immunological responses; evidence that early-life intestinal colonizers may influence brain development; and a new tool, pepFUNK, which uses a peptide-centric approach to identify KEGG pathways in metaproteomic datasets. Enjoy!

Hi everyone! This is my first contribution to the daily digest, and I’ll follow others’ lead by starting with the latest preprints concerning Covid-19. Away from the ongoing pandemic, some of the highlights include a look at how commensal gut microbes interact with pathogens, and an insight into deep sea oceanic crust microbiomes.

It seems to be a relatively quiet day today, so I’ve included an article from the University of Bristol which looks at how nanoscopic pillars on the surface of some insect wings protect them against bacteria. Perhaps only loosely a microbiome paper, but it’s worth a read for its electron microscopy alone!
