The Everything Bagel feature finder automates metabolomics data processing, achieving comparable or better performance than existing methods with significantly reduced computational time.

A frameshift mutation drives divergent biosynthesis of metallophores in Methylobacterium extorquens

This study identifies a frameshift mutation in M. extorquens AM1 that drives the production of methylolanthanin instead of rhodopetrobactin by altering the biosynthetic pathway.

Bacteroides fragilis modulates gut microbiome community composition, frontal cortex gene expression, and fecal and frontal cortex metabolites in a mouse model of Alzheimers disease pathologies

This study shows that Bacteroides fragilis treatment in AD mice alters gut microbiota, reduces neuroinflammation markers, and normalizes brain metabolites.

Metal homeostasis is remodeled in response to different quiescence triggers

The paper investigates metal homeostasis changes in quiescent cells induced by different triggers and finds trigger-specific remodeling of metal pools and associated gene expression.

Cooperative siderophore use stabilizes a protective leaf microbiome

The paper shows that cooperative siderophore exchange between Rhodotorula kratochvilovae and Pseudomonas species stabilizes the leaf microbiome and protects plants from pathogens.
