The winding trail of environmental microplastics leads researchers to the human digestive ecosystem.

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. 

A high-fat diet induced changes to the animals’ vaginal microbiomes that boosted survival after exposure to the virus.

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.

Studies are finding that a single course of antibiotics alters the gut microbiomes of healthy volunteers—and that it can take months or even years to recover the original species composition.

A study shows that a molecule produced by intestinal microbes can enter the brain and that its presence is also associated with altered brain connectivity.

Recent studies describe how resident microbiota appear to outcompete unwelcome visitors, either with superior weaponry or by guzzling up local resources.  

Work in rodents shows that the bacteria living in a mother’s gut can produce immunomodulatory metabolites and influence the production of maternal antibodies—both of which can affect her offspring’s development.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

The microbiota helps align a mouse’s innate immune system with its feeding patterns, prepping the animal to fend off infection when it’s most likely to be eating.

The temporary loss of olfaction stops the flies from eating any more of whatever it is that made them sick.

After controlling for high levels of bacterial contamination in their lab and reagents, researchers detect microbial genetic material in plasma samples from healthy people and cancer patients.

A study of 19 postmenopausal women found that eating a bar of chocolate in the morning affected their bodies differently than eating it at night, but neither led to weight gain.
