January 24, 2021

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.
