This paper develops a method for direct electrochemical cortisol detection using a defect-engineered graphene interface and transition-resolved interrogation, achieving sensitive and selective detection in biological fluids.

The paper shows that modifying microbial community composition, specifically overexpressing bile acid metabolic genes in Lactobacillus strains, can alter bile acid pool size and composition in mice.

The paper uses a single-strain dropout screen in a defined microbial community to show how removing specific strains affects community composition and metabolic output.

This study shows how initial population size and resource competition shape gut microbial community coalescence, with dose-dependent effects persisting even after many generations.

Rapid QC-MS provides an automated dashboard for real-time quality control of LC-MS/MS data, improving efficiency and accuracy in untargeted workflows.

This study characterizes transcriptomic and metabolomic profiles in human urine, identifying distinct cell type repertoires and metabolic signals compared to plasma.

This paper uses evolutionary genomics to identify host metabolic pathways critical for intracellular bacterial survival, validating them through in vitro assays and metabolomics.
