This study shows milk urea increases during lactation, is conserved across mammals, and supports infant gut microbiome establishment through urea-metabolizing bacteria.

This study identifies raffinose as a dietary fiber that promotes bifidobacterial persistence in the gut during weaning, with implications for host health and inflammation.

A gut consumer-resource model with explicit metabolic pathways yields competition-dominated healthy and cooperation-dominated dysbiotic states; an interaction-balance index (ENBI) detects this shift in human disease cohorts.

This study evaluates cryopreservation methods for stool samples to maintain viable microbiota, finding that simple methods like glycerol preservation and snap-freezing are as effective as more complex protocols.

This paper expands the interpretability of human metabolomes by using food-based annotations, increasing the fraction of molecular features understood 7-fold.
