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!

Today’s non-microbiology pick is an opinion piece on the current state and limitation of viral taxonomy. In this piece, Simmonds and collaborators, provide concrete recommendations to guide the development of a coherent and comprehensive virus taxonomy.

Have a great Saturday!

Bonjour from Paris, France !

In today’s digest you will find a wide variety of interesting preprints and published research papers encompassing very interesting microbiome such as Yak calves rumen, compost, wineyard soil and lichen symbionth microbiota!

If you are interested in virome, I recommend looking at the fascinating preprint from Ha and collaborators investigating the biogeography of giant viruses from the phylum Nucleocytoviricota. They leveraged the bioGEOTRACES metagenomic dataset collected across the Atlantic and Pacific Oceans to recovered novel genomes from these viruses and identified geographical patterns of distribution.

If you are working on human microbiomes, I recommend checking out a really interesting preprint, comparing the biases and strengths of four commercially available DNA extraction kits frequently used for whole genome shotgun analysis of the human microbiome.

Have a great Saturday!
