Hello from the Sonoran Desert! In today’s digest, you’ll find two very interesting reviews! Stagaman and collaborators come back on years of Zebra-fish gut microbiome research and explore the insights gleaned from this awesome model animal. On the other hand, François and Pybus review our understanding of avian viromes in both wild and domesticated bird populations, highlighting the current limitations and pitfalls in this research area.

But today’s digest also contains very interesting research papers! Gulino and collaborators are exploring viromes in New York city wastewater systems. This paper is particularly interesting as bacteriophages are typically left out from urban environments microbiomes studies, despite their abundance and importance in ecosystems.

Finally, today’s non-microbiology pick is a review that comes back on how information theory, developped by Claude Shannon in the late 40s, have been used in computational biology. This paper is particularly interesting for readers wanting to learn more about the basics of information theory and how it is applied today in bioinformatics.

Have a great Sunday!

There is also an interesting article about species identification errors occurring in context of large sequence collection platforms.
And to mix things up a little bit, at the end of a list you find a paper with amazing microscopy featuring the beautiful parasite Trypanosoma brucei and answering the endless question to how this parasite colonizes its insect host, the tsetse fly.
