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.

Good morning all! Today’s digest includes two articles discussing the role of the local tissue microbiome in cancer. In the first, Zhu et al. explore the relationship between the intratumor microbiome, immune cell infiltration, and patient survival in the context of melanoma. The second study by Wilkie et al. examines how lipopolysaccharide produced by the commensal breast microbiota impacts cancer growth.

Additionally, there is a paper by Radojević et al. in which the authors found an association between the fecal microbiota and immunogenicity of peripheral blood monocyte-derived dendritic cells in healthy donors; a study by Kim et al. showing that diet and microbiome derived amino acids impact gut enterocyte communication with the brain in Drosophila; and a paper by Tandon et al. investigating the impact of the reciprocal transplantation of water from the surface and bottom of lakes with different trophic states on microbial community composition and function.

Hyvää Päivää from Helsinki, Finland ! Today’s digest contains a variety of interesting papers, in particular in bioinformatics! I recommend anyone interesting in metagenomic read classification to take a look at the benchmark study by Arizmendi Cardenas and collaborators. They compared read-based taxonomic classification tools on their capacity to handle ancient DNA sequences, characterized by a higher mutation rate and shorter sequences.

This digest also contains a very good review on the current state of the art network analysis methods for exploring interaction in complex microbial communities.

Finally, today’s non-microbiology pick is a piece exploring the current challenges and limitations for the annotation of microbiome dataset with high-quality metadata.
