A jolt of norepinephrine in the mouse gut facilitates colonization by certain microbes, which in turn deplete glycine, enhancing cocaine-induced behaviors.

The unique odor profiles of tumors can be used to develop diagnostic sensing tools.

Centenarians have distinct microbiomes with species that produce unique bile acids, which may help thwart illness.

Researchers integrated information from 45 protein, metabolite, and immune data points to identify a window two to four weeks before a pregnant person will go into labor.

The gastrointestinal tracts of people with major depressive disorder harbor a signature composition of viruses, bacteria, and their metabolic products, according to the most comprehensive genomic and metabolomic analysis in depression to date.

The study of diet, long plagued by inaccuracies in self reports, is entering a new age of precision with the methods of metabolomics.

Nutrition researchers are beginning to use metabolomics to determine how healthy subjects’ diets are, and even to reveal specific properties of the foods they eat.
