Welcome to another post from a new volunteer! I’m a Ph.D student studying the infant gut microbiome and I’m excited to be volunteering with Microbiome Digest.

There are several preprints today, including another great study from the CHILD cohort. This one is on maternal consumption of artificially sweetened beverages and the infant gut microbiota. There is also a preprint calling for improvement in scientific conferences. Both are highlighted in green.
