Greetings from Pittsburgh, PA!

It’s election day here, which means I have low grade nausea and am looking for a distraction. If you’re in the same boat, check out today’s awesome articles on a holobiont deep sea shrimp, plant-microbiome assemblies of poplar trees, and viral community-wide auxiliary metabolic genes. I also included a few interesting preprints, my favorite of which is noted below and uses a microbiome public dataset to compare different normalization and transformation methods.
