Good morning! There’s a particularly broad collection of microbiome papers to share with you today, from the bacteria that hang onto wounds after debridement to the biofilms that form in the ancient ruins of a town buried by the eruption of Mount Vesuvius. A few unusual highlights include the sexually transmitted microbiome of bedbugs and the gut microbes that colonize a sea cucumber after it grows up, remove its own digestive tract and grows a new one. Some interesting new software tools are hiding in the “Bioinformatics” section at the bottom as well.

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!!!!
