Hello from the Sonoran Desert! In today’s digest, you’ll find great papers, in particular in soil and water microbiology but also in bioinformatics! As an example, Mara and collaborators are exploring the viruses found in the oxygen-deficient water column of the Cariaco basin. Interestingly, a large diversity of viral Auxilliary Metabolic Genes (AMGs) were found and give new insights in how phages may interact with their bacterial hosts in this understudied ecosystem.

In the bioinformatics section, I recommend anyone interested in phage metagenomics to take a look at the paper from Ren and collaborators. The authors have developed a reference-free and alignment-free deep learning tool, called DeepVirFinder, allowing the retrieval of viral sequences in metagenomes.

Today’s non-microbiology digest is a paper announcing the last update of the Genome Online Database (GOLD), a manually curated collection of genome projects and their metadata from around the world, which now contains more than a million entries! Great news for bioinformaticians!

Have a great Saturday!

Happy Monday morning from San Francisco, California! Hope everyone had a restful weekend. For those who aren’t quite ready for the working week, how about easing in to things with a warm beverage and some great microbiome reads?

Today’s digest includes two papers that blew my mind. The first is a paper by van Tatenhove-Pel et al. which looks at how cell-to-cell distance in 3D space impacts the metabolic interactions between bacteria. The second, by Nowosad et al., examines the role of the gut microbiota on B cell selection and antibody affinity maturation in gut-associated germinal centers. Other fascinating papers include: a pilot study profiling the gut microbiomes of South Africans in an urban cohort and a transitioning rural cohort which was designed collaboratively with community leaders (Oduaran et al.); a review paper about using brachyuran crabs as a model for studying how animal-microbiome symbioses evolve when aquatic organisms transition to land (Cannicci et al.); and a paper that used shotgun metagenomics to identify current and historical microbiomes in lake sediment which could help our understanding of how humans impact lake ecosystems over time (Garner et al.). Happy reading, y’all!

Hello, friends!

I’m an American who grew up in North Carolina, lived in Georgia for many years, and now counts Pennsylvania as home. All of this is to say, I’ve been especially consumed by the US election this morning and so today’s digest is tailor made to distract me for a few hours. It contains a heavy dose of general microbiome, environmental microbiology, and microbial ecology articles. If you need a bigger distraction than usual, I’ve highlighted a few articles that I am particularly looking forward to reading and am using this space as an opportunity to reintroduce myself and share why these articles have peaked my interest.

I completed my PhD research on the cockroach gut microbiome and through this work, I realized how complex microbiome-host-environmental interactions can be. Because of this, my first highlighted article is a review about cockroach-associated microbes. Currently, I work in a national lab studying environmental-associated microbes (and their functional capacity!) in a variety of different energy-associated environments. It’s no wonder I’m excited to read the second highlighted article focused on novel soil microbes found in an abandoned coal mine! I’m also very hungry at the moment, so as soon I read the phrase “smoked cow cheese” I was motivated to explore my cheese drawer as well as think more about microbial food safety and the microbial production of favor compounds. Finally, I love musical theater and science outreach, so I’m delighted to share a mouldy article that combines both passions.

Happy reading, everyone!

November 1, 2020

Hello from the Sonoran Desert! In today’s digest, you’ll find several interesting works, in particular on recent advances in understanding the gut microbiome! Iandaza and collaborators review the rise of machine learning and deep learning methods in exploring the gut microbiota and the potential of these methods in the diagnosis and treatment of diseases. Additionally, this digest links to a freely-accessible webinar series from the university of Illinois on gut-brain connections.

If you are interested in microbial ecology, I also recommend taking a look at a very interesting preprint from Ettinger and collaborators. The authors investigate the distribution of fungi associated with a widely distributed seagrass, Zostera marina. This work is particularly relevant since the role and diversity of fungi in marine ecosystems are often overlooked in microbiome studies, while terrestrial fungi have been shown to have critical roles as decomposers, pathogens and endophytes.

Finally, you’ll find in this digest a non-microbiology pick: an amazing preprint where authors assessed 2.75 million open access articles on their transparency (data sharing, code sharing, conflicts of interest disclosures, funding disclosures and protocol registration)!

Have a great Sunday!

Good morning from sunny San Francisco, California! Today’s digest shares some fascinating in vivo studies including a paper from Ou et al. examining the role of host antimicrobial proteins α-definsins in bacterial colonization and epithelial cell adherence in the gut and a proof-of-concept paper from Hsu et al. in which the authors orally delivered an engineered phage to the gut of mice that was capable of specifically repressing gene expression in bacteria. Additionally, there are some great plant, root, and soil microbiome papers (Kusstatscher et al. show that treating maize seeds with a plant growth-promoting rhizobacteria improves plant health) and water microbiome papers (León-Zayas et al. published a super collaborative paper looking at microbiome sharing between sediments, seagrasses, and reef fish at multiple sites). Finally, I wanted to highlight a paper by Zelaya et al. outlining a course-based undergraduate research experience for teaching microbiology that focuses on the bean beetle microbiome.
