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.

Hyvää Päivää from Helsinki, Finland ! Today’s digest contains a wide range of topics to explore! I particularly recommend taking the time to read at the fascinating review listed below exploring horizontal gene transfer in environmental microbial communities. They describe how advances in the computational analysis of metagenomic data has allowed us to dive deeper in understanding these processes in microbiomes.

Among the list of very interesting research papers in this digest, you’ll find a fascinating study exploring the symbiotic microbial communities associated with deeper corals. Although extensive litterature has been published on coral microbiomes from shallow waters, this papers is the first to examine microbial communities associated with the deep photosymbiotic corals, living at more than 150 m of depth!

Today’s non-microbiology pick is a really interesting paper from Faldelmola and collaborators reporting on the development by the Pan-African H3Africa Bioinformatics Network of two data portals for African genomic medicine and African microbiomes datasets. The paper explore how they lead a very successful 6-days hackathon allowing to efficiently develop these two important scientific ressources, but also how they build a collaborative community of African researchers and experts.
