Alex Mohr discusses a trial comparing various calorie-restricted diets on the gut microbiome and overall health measures.

Gut viruses influence behavioral responses in mice and may be important players in the gut-brain axis.

Diet influences the microbiome. When new foods enter the mix, it gets complicated.

Dietary changes rapidly alter T cell metabolism, but the effects can be reversed.

NIST has spent years developing a human fecal reference material.

Researchers took a mind-bending trip to understand the connections between psychedelic compounds produced by fungi, plants, and humans.

Psychedelics are evolutionarily ancient compounds produced by fungi, plants, and microbes. Humans also synthesize psychedelics. Researchers want to know how and why.

Fecal transplants may help scientists improve current treatment strategies for anorexia nervosa.

Levels of health-promoting gut bacteria are linked with severity of fatigue symptoms, a study finds.

A neural pathway between the gut and the brain led to the release of dopamine when the mice ran on a wheel or treadmill, but only in the presence of a robust microbiome.

The gut microbiomes of city-dwelling animals, including coyotes, lizards, and birds, show similarities to those found in humans who also live in urban environments.

Milk fortifiers of human origin show no evident advantage in the development of the gut microbiota of premature infants over fortifiers derived from cows, while the intake of the mother’s own milk does, two studies suggest.

When consumed for as little as two weeks, common alternatives to sugar affect intestinal bacterial communities, with some reducing the body’s ability to regulate blood glucose levels, a study finds.

Aimée Parker shares how her childlike curiosity and collaborative spirit motivate her scientific pursuits.

IgA antibodies appear to bind to specific species of commensal gut bacteria in mice, according to a study.

Researchers are going beyond fecal samples to understand how the patterns of commensal microbes in the gastrointestinal tract influence development and health.

Experiments in animals and observations in humans suggest that the amount of proline circulating in one’s plasma has a strong association with depression severity.
