A brief guide to statistical analysis of grouped data in preclinical research - Nature Metabolism
Clustering and nesting (C&N) arise in many preclinical studies, such as when animals are group-housed or share litters, or in cell culture. Ignoring C&N undermines the validity of analyses. Here, we explain how C&N arise, as well as valid designs and analyses.

Microbiomes are the foundation of the biosphere. Hosts such as humans, bees, and plants have never been just hosts. They are complex units of biological organization upon which various forces act to shape composition, form, and function. www.science.org/doi/10.1126/...

💥 Excited to introduce Bacformer 🦠 - the first foundation model for bacterial genomics. Bacformer represents genomes as sequences of ordered proteins, learning the “grammar” of how genes are arranged, interact and evolve.
