Good morning from Northern Germany,

Today’s selection comprises among others new research about intestinal microbiome and breast cancer (by Koren lab), a perspective about the human microbiome in the 21st century and the diversity in marine sediments. Additionally, we selected a study about linking genetics, microbiome and autoimmunity (multiple sclerosis) in a mouse model and a study about postmortomics.

Conferences

The 3rd Microbiome Movement – Skin Health & Dermatology Summit unites leaders from academia and industry to address the unique challenges that working within the skin microbiome possesses, with the goal to accelerate microbiome-targeted therapeutics and cosmetics.

Hello from Lübeck/Germany,
today we cover a broad range of microbiome related studies. Of particular interest is a preprint by the Korem lab about use of antibiotics and increase in aggressive behavior in D. melanogaster. This study got already some attention on Twitter and in the press. Furthermore, one preprint covers the C. difficile species problem, investigating the genetic heterogeneity of this species. Last but not least, I would like to mention a paper investigating responses of megakaryocytes, erythroid cells and plasmablasts as hallmarks of severe COVID-19 trajectories.
