October 12th, 2021

Bonjour from Paris, France ! Today’s digest contains a selection of really interesting preprints and published studies. In their review, Heilbronner and collaborators explore the role of bacteriocins, small antibacterial molecules produced by many commensal bacteria in human-associated microbiomes. The role of the bacteriocins in the human microbiome is of particular importance since they could be leveraged to specifically target colonizing pathogens while sparing mutualistic patners.

If you are interested in exploring new bioinformatic methods, I recommend taking a look at the study from Cheng and collaborators, who applied a novel iterative random forest approach to explore marine microbiome during algal blooms. They show how this model allow to identify conditions that are important causal factors of algal bloom dynamics.

Today’s non-microbiology pick is an opinion piece reflecting on the possible methods to develop the field of computational biology, ensure proper training and career development in this discipline and allow a greater collaboration between domain biologist and data scientists in multidisciplinary teams.

Have a great Tuesday!
