Good morning from Massachusetts! Dr. Elisabeth Bik will be giving a Zoom talk today on research misconduct in biomedical research. You can register at the link under events. Fittingly, today’s digest includes a preprint on the effects of retraction after misconduct on citations. Other highlights today include an entire theme issue on the microbiome and host evolution and a paper on phylogenomic analyses of archaea attempting to elucidate the DPANN lineage. In early life, the placental microbiome debate rages on with a paper demonstrating evidence for contamination rather than an actual placental microbiome. Finally, I have highlighted a paper studying whether soil archives can give us a glimpse into soil microbial communities of the past.

Have a great weekend!

God morgon!

Good morning from Sweden. Today’s digest is a light one but carries a preprint with some very important findings. The study has suggested that the nCoV can potentially hijack the immune system completely by infecting the lymphocytes. This might lead to impaired antibody and T-cell response, something that could have a serious implication on the success of the much-awaited vaccine. (Unfortunately, for some unknown reasons, the PDF of the preprint is inaccessible to me! Let me know down in the comments if you are able to download it.)

A new paper in BMC microbiome shows a correlation between the indoor dust microbiota and the microbiota of infant airways. A classic example of how our environment impacts our health.  There is another interesting preprint where the authors show that a fungus alters its virulence when it is challenged by predatory amoebae. Perhaps the amoeba challenge selects for the warrior mutants which then carry on their warring ways!

Elsewhere in the digest is a preprint where Plasmodium knowlesi was used as a model to successfully determine new vaccine targets against more dangerous Plasmodium vivax, a paper detailing the effect of polar light cycles on the Antarctic lake microbiome, and identification of haloarchael species in Korean gut microbiota.
