Bonjour from Paris, France !

In today’s digest you will find a broad range of amazing preprints and published papers! Fontana and collaborator performed a fascinating meta-analysis of publicly datasets obtained from fecal samples of healthy athletes and healthy sedentary adults and revealed the microbiota changes associated with competitive athletes lifestyle.

Today’s non-microbiology pick is an preprint exploring postdoctoral and PhD student’s career self-efficacy in US biological sciences and showed how women and non US citizen have a significant lower level of career self-efficacy compared to their male and US citizen peers. The authors discuss potential causes for these differences and offer recommendations for increasing trainee career self-efficacy.

Bonjour from Paris, France !

In today’s digest you will find a broad range of amazing preprints and published papers! An amazing read is a fresh preprint from Fritz and collaborator describing an exciting method of sampling in difficult to reach environments. The authors used army ants of the genus Dorylus which are foragers to survey the viral diversity of plants, vertebrate and invertebrates of the tropical forest!
