Today’s digest consists of opinion paper from European MyNewGut project, review article on gut microbiota dysbiosis, and meta-analysis to find association between antibiotic associated microbiota perturbation and childhood obesity. Also includes application of contraceptive rings and probiotic capsules to increase vaginal lactobacilli, and how preprint publishing could create confusion in public journalism!
