It is with deep sadness that we share the passing of Professor Jeff Cole. An esteemed academic, Jeffs research on bacterial adaptation to oxygen and nitrosative stress made a lasting impact on the field. He mentored nearly 60 doctoral students, our thoughts are with his family, friends & colleagues

The disputed identity of Pseudomonas putida KT2440: when taxonomists rename your favorite microbe | mBio Names matter; they are not mere labels.

Metabolites are not genes β€” avoiding the misuse of pathway analysis in metabolomics - Nature Metabolism Pathway analysis, originally developed for gene expression data, has been adapted for metabolomics. However, owing to the unique characteristics and constraints of metabolites compared with genes, pathway analysis in metabolomics often yields misleading or nonsensical results.
