Greetings from Pittsburgh, PA!

Today’s digest includes several reviews, numerous host-microbiome studies, a wide variety of environmental microbiome studies, and a new book focused on Emerging Technologies in Environmental Bioremediation.

I also wanted to highlight the virtual Fermentation Mini-Seminars offered by the Applied Ecology Department at my alma mater, NC State University. During the first seminar of the series I learned about the Wild Sourdough Project, which is a community-science/citizen-science project where participants can submit observational data about their sourdough culture. If you’re missing the lab, this might be the perfect project for you!

Hello from the Sonoran Desert! It is a lovely morning here in Tucson, Az. I am excited to send my first contribution to Microbiome Digest! There is a lot of diversity in today’s digest, but if microbes thriving in all kinds of strange, extreme conditions are your area of interest, you’ll be interested in the book compiling the latest studies on extremophiles. Each chapter focuses on a particular environment, ranging from deserts to deep-sea hydrothermal vents, and explores the mechanisms allowing microbes to survive these incredible conditions.

If like me, you are a computational biology enthusiast and a machine learning addict, you should enjoy reading the last entry, a short perspective paper examining how machine learning algorithms can help predict antibiotic resistance!

Have a great Sunday!

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.
