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.

Good morning and a wonderful Sunday!
While you are eating your Sunday eggs and sipping your coffee, enjoy the small collection of microbiome et al. papers- exactly the right size for a Sunday morning.
Visit the microbial community living at Antarctic volcanoes with the preprint from Benda et al. or read the findings by Gibb et al. that indicate that human-managed ecosystems favor the presence of reservoirs of zoonotic diseases- very interesting in the light of the current pandemic. Enjoy!

Hello from the Sonoran Desert! In today’s digest, you’ll find find a lot of very interesting papers! For those interested in host-phages interactions, there is an amazing work from Ping and collaborators looking at phage infections dynamics in migrating bacterial populations. Interestingly, the authors suggests that phages may be able to “hitchhike” with moving bacteria.

To continue with our viral readings, you’ll also find an interesting perspective paper from Kuprovic and collaborators. In this piece, the authors attempt to reconstruct the virome associated to LUCA (Last Universal Cellular Ancestor). Amazingly, their reconstruction shows that a remarkably complex virome would have been associated to LUCA, suggesting an extensive viral evolution antedating LUCA!

Finally, today’s non-microbiology pick is a book, looking at the fascinating Cuatro Ciénegas Basin, located in México, a site that is often described as a real outdoor laboratory for astrobiology. Indeed, the Basin site contains gypsum-rich soil analogous to the Gale Crater in Mars, and the ponds contains extremely oligotrophic waters, which can be used to model ancient oceans chemistry. You’ll explore along the chapters the history, ecology, microbiology and evolution of this amazing site, to unravel the mysteries of this site absolutely unique on the planet.

Have a great Sunday!

There are several notable entries in today’s digest. Registration is open for the European Learning Laboratory for the Life Sciences’ “Introducing Your Microbiome” virtual training course. The course is for European secondary school science teachers and is 5 weeks long. The 3rd Microbiome Movement will also be held this year, both virtually and in-person. Links are in the Events section.  

Today I’ve highlighted a bioinformatics paper on variant calling for cpn60 barcode sequencing and an early life paper on pre-term infant stem cell proliferation upregulated by microbial metabolites. While putting this digest together, I learned algae turns snow different colors! This is so cool to me that I’ve highlighted that paper as well. Finally, the News section includes an article for Smithsonian Magazine by Rob Dunn on quarantine’s effects on our microbial passengers.  

Happy reading!
