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.

Hyvää Päivää from Helsinki, Finland ! Today’s digest contains quite a lot of different topics. If you are interested in marine microbiology and virology, I recommend taking a look at the paper by Gazitúa and collaborators. 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.

Greetings from Pittsburgh!

Today’s digest has a lot of food and agriculture associated articles. Several articles focus on the effects of various pathogens on dairy cows, beef steers, and poultry breeds! For those of us who are more interested in plants, there is an article on biogas production from tomato waste and a preprint on how the microbial community of food waste changes during the composting process. Finally, I included a research article about social media during the pandemic since I’m sure I’m not the only one who has relied on it a little too heavily over the last year…

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.

Although I’m not sure what the distribution of COVID-19 vaccines is expected to look like, today’s digest includes an article mapping routine measles vaccination coverage in low- and middle- income countries. I’ve also highlighted a few interesting environmental microbiology preprints, including one on the role of ecosystem engineers in shaping arid soil bacterial communities.
