Greetings Everyone,
I want to began the month of July on a note that diversity is the basis for life. I can’t think of anything better to teach us about diversity, co-existence, and evolution than the fascinating Microbiome.
The microbiome affects us right from our birth till the end affecting our mental as well as physical health. The microbiome exhibits all sorts of differences in shape, size, color, metabolic functions in order to sustain life.
Much to learn from these tiny beings!!!!
Today’s Digest comprises of some interesting studies about effect of microbiome on chemotherapy and studies on tumor microbiome. It also includes articles exploring genetics of gut microbiome and the role of microbiome in inflammatory bowel disease. Additionally has a news article about taking microbiome therapies to clinical trials.
Hope you enjoy reading today’s digest!!
“Life on earth is such a good story you cannot afford to miss the beginning… Beneath our superficial differences we are all of us walking communities of bacteria. The world shimmers, a pointillist landscape made of tiny living beings”. – Lynn Margulis

Greetings from Pittsburgh!

Today’s digest is unintentionally themed around change. Included is an article on the metabolic versatility of Salmonella enterica and another on the genetic diversification of Escherichia coli. If you’re more interested in the big picture, there is also an article about the evolution of ecological niches in plant-associated microbes as well as an article about the impacts of global change on soil microbial diversity and functionality.

Here’s to hoping that we are just as resilient as the microbes we study!

May 19, 2020

Good afternoon from sunny South Wales!

Today’s digest has a lot of great papers, with something for just about everyone. We’ll start off with a bang, and highlight a great paper in which Rajasekaran and collegaues challenge the current dogma that human intervertebral discs are sterile using a 16S rRNA sequencing approach.

We then have an interesting, or perhaps concerning paper looking at the prevalence of underreported parasites in laboratory zebrafish populations. A must read for anybody using zebrafish models. We also have plenty of papers concerning plant and water microbiomes, including a rather huge report on ocean systems.

Finally, with the current health climate, what better paper peruse than the contribution of Qureshi et al. who have demonstrated that gender neutral bathrooms are more rapidly colonised than single gender bathrooms. If recent anecdotal news articles are to be believed (although they seldom are) it’s usually the men letting the side down. You’ve got to wash those hands!

I hope everyone is staying safe, and enjoys today’s post!

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!
