Several great papers today including a very interesting Cell paper on how Bifidobacterium interacts with the immune system and an mBio article on how different types of dietary fibre shape the gut microbiota.

To our Australian readers I’d like to wish a happy NAIDOC week, which is a time to celebrate the history, culture and achievements of Aboriginal and Torres Strait Islander peoples.

Hyvää Päivää from Helsinki, Finland ! Today’s digest contains a selection of interesting gut microbiome papers and preprints. In particular, Beller et al. looked at the succession of microbial communities in the infant gut from birth to 1 year of age. This digest also contains some very interesting works on environmental microbiome, as an example, Wasmund et al. investigated bacterial taxa able to degrade extracellular DNA in marine sediments.

For those interesting in bioinformatic tools and methods, this digest also contains the description of novel data ressources and tools. In particular, Pellow et al. present a new tool, SCAPP, allowing for a better assembly of plasmids from metagenomes.

Finally, today’s non-microbiology pick is a paper looking critically at the open source citation advantage effect (the hypothesis that articles made available open access may benefit from an increased number of citation) by conducting a meta-analysis of previous studies.
