Greetings from Durham, NC!

Hope everyone is doing well and staying healthy. Today’s digest includes several host-microbiome studies, environmental microbiome studies, and an intriguing EurekAlert news article.
In this light digest of today, I wanted to highlight a cool review about correlation of the oral microbiome with children’s health and a very interesting article on cell wall architecture of the gram-positive bacteria.
COVID-19 pandemic has opened a sort of Pandora’s box filled with great science along with pseudoscience. So, the digest has these two great articles from Nature: one about chloroquine and other about the race for coronavirus vaccines.
Staying at home is difficult for everyone, here is a fun activity to do: coloring space microbes book.

Stay Safe and entertained at home!!!!

Hello all from another new Microbiome Digest volunteer! This post is coming to you straight from the heart of New York City – being surrounded everywhere by COVID-19 (and related research!), it’s been good to get back into the microbiome world 🙂 I love all things microbiology but am partial to bacteria, especially multidrug-resistant pathogens and communities involved in biological nutrient removal/recovery from waste.

Today’s roundup is heavy on the soil and environmental microbiomes and some interesting preprints, with some unique finds – indigenous yeasts in winemaking, gut microbiomes after dietary interventions in adult dogs, and much more!

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!

Good morning! There’s a diverse set of microbiome papers to share today, ranging from the human microbiome in Lynch Syndrome to the microbes that flavor wine and degrade paintings in art galleries. You may also want to check out the recent news that popular video game Borderlands 3 is introducing a new mini-game that prompts players to help “map” the human gut microbiome—technical details are hard to come by, but it appears to be alignment related. There is also a study that found more than 20 percent of recently published metagenomes are not accessible.

In addition, Microbiome Data Congress 2020 will be held online on May 6 and is offering free registration through tomorrow (Friday, April 10). Speakers include human microbiome researcher Dr. Nikos Kyrpides of the (U.S.) DOE Joint Genome Institute and soil microbiologist Dr. Kari Dunfield of the University of Guelph.

All the break-neck speed with which the progress that is happening today in tracking, detecting and treating the disease, like everything else, is owed in part to the giants whose shoulders we’re standing on. One such thing is the usage of serum (from recovered patients or derived elsewhere) for treatment. So, as a little tribute, I would like to share with you today, on the birthday of Dr. Hattie Elizabeth Alexander (born April 5, 1901), the information that she pioneered the work in using anti-influenzal rabbit serums to treat the then always-fatal influenzal meningitis (effectively bringing down the fatality rate to 20%!), and was also sone of the very first to study bacterial mutations that come along with antibiotic resistance !

So we’ve come a long way and are forging our way forward. Here are a few interesting articles that are slowly pushing this boundary, a piece at a time.

PS: I know, I am with you on this — the lockdown isn’t ideal. But we are also the generation, who for the first time can end articles signing off as “Stay Safe and Wash Your Hands” and manage to prevent a large proportion of its species from suffering / dying. Isn’t that crazy! Have a great day!
