Hyvää Päivää from Helsinki, Finland ! Today’s digest contains a selection of really interesting preprints and published studies. If you are interested in soil microbiology, take a look at the preprint by Nelson and collaborators, who characterized the soil microbiome across a wildfire burn severity gradients in coniferous forests and made their dataset available in the Fire Responding Ecogenomic database (FiRE-db).

Looking at a large variety of ecosystems, Rodriguez-Gijon and collaborators used a vast collection of Metagenomes Assembled Genomes (MAGs), to investigate the genomes size of prokaryotes in these ecosystems. They show that, while the environment of origin can be linked to genome size, it seems like evolutionary phylogenetic history is in many cases a stronger predictor.

Finally, today’s non-microbiology pick is a great “10 simples rules” paper reviewing best practices on organizing bioinformatics workshops in low and middle-income countries.

Have a great Weekend!

April 24th, 2021

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.

In this study they investigated the role of phages in shaping the metabolism metabolic networks along redox gradients associated with marine oxygen minimum zones. To do so, they investigated the phage contents in auxiliary metabolic genes involved in bacterial photosynthesis, central carbon metabolism, and nutrient cycling.

Hyvää Päivää from Helsinki, Finland ! Today’s digest contains quite a lot of different topics. If you are interested in gut microbiomes, I recomment taking a look at the preprint by Weiss and collaborator. In this study, they explore bacteria-bacteria interactions, bacterial growth and metabolic interactions in a synthetic bacterial community: the Oligo-Mouse-Microbiota, which is increasingly used as model system in gut microbiome research.

Additionally, anyone interested in microbiome-based forensic tools should read the study from Sang You and collaborators.  They compared the composition of microbial communities in blood spot surfaces placed in different environments sampled across seasons and time points, in order to evaluate the environmental factors leading to variation in these microbial communities.

Today’s non-microbiology pick is a fascinating study looking at the prevalence of COVID-19 related misinformation among the Yemeni population and its association with vaccine acceptance and perceptions. From this study, the authors recommend the deployment of awareness campaigns to decrease misinformation before initiating any mass vaccination in Yemen.

Hyvää Päivää from Helsinki, Finland ! Today’s digest contains quite a lot of different topics. If you are interested in  early-life microbiome, I recommend taking a look at the paper from Mortensen and collaborators. To understand the role of the maternal vaginal microbiome’s in seeding their child and the importance of the delivery mode in early-life microbiome acquisition, they studied 665 mother–child dyads and modeled the transfer of the vaginal microbiota from mother to infants.

In today’s digest, you’ll also find a really interesting preprint from Abiriga and collaborators, looking at the microbiome of a groundwater aquifer contaminated by a municipal landfill while undergoing intrinsic bioremediation. This preprint is particularly notable because studies looking at the microbiome of contaminated aquifers are particularly rare, despite groundwater contaminations from landfills being a very common issue.

Today’s non-microbiology pick takes a look at the difficulty of detecting scientificly fraudulent images produced by Generative Adversarial Networks (GANs). They demonstrate that this deep-learning method can generate realistic western blot images that are indistinguishable from real western blots. In conclusion, the authors argues that additional information should be required to ensure that the western blots published in scientific publication are not generated images.

Joyeuses fêtes from Paris, France ! In today’s digest, you will find great papers looking at various animal and plant microbiomes. In particular, I recommend taking some time to look at a preprint from Brealey and collaborators exploring the impact of human antibiotic use on oral microbiome in wild animals. The authors used shotgun metagenomics to determine the abundance and diversity of antimicrobial resistance genes in the oral microbiome of brown bears from Swedish museum specimens. Importantly, they show a significant increase in antimicrobial resistance genes in correlation with modern human antibiotics use, showing an impact even on wildlife of our antibiotic consumption.

Today’s non-microbiology pick takes a look back at the history of bioinformatics through the data analysis and visualization of papers published between 1998 and 2019. In addition of reading this very interesting paper, you can take a look at the data collected through interactive visualizations available at http://bioinfo.dcc.ufmg.br/history !

Hello from the Sonoran Desert! In today’s digest, you’ll find great papers, in particular in soil and water microbiology but also in bioinformatics! As an example, Mara and collaborators are exploring the viruses found in the oxygen-deficient water column of the Cariaco basin. Interestingly, a large diversity of viral Auxilliary Metabolic Genes (AMGs) were found and give new insights in how phages may interact with their bacterial hosts in this understudied ecosystem.

In the bioinformatics section, I recommend anyone interested in phage metagenomics to take a look at the paper from Ren and collaborators. The authors have developed a reference-free and alignment-free deep learning tool, called DeepVirFinder, allowing the retrieval of viral sequences in metagenomes.

Today’s non-microbiology digest is a paper announcing the last update of the Genome Online Database (GOLD), a manually curated collection of genome projects and their metadata from around the world, which now contains more than a million entries! Great news for bioinformaticians!
