There’s a lot that scientists don’t know about the gut microbiota, and when it comes to the viruses present there they know even less. To
Researchers have identified one possible cause of nonalcoholic fatty liver disease, a common disorder in which fat builds up in the liver with potentially life-threatening
Mounting evidence in animal models, as well as correlative studies in humans, indicate that the microbes present in the gut can shape immune responses. In
When Sara Campbell first typed “exercise and microbiome” into PubMed in 2010 and hit enter, “the search literally said zero,” she tells The Scientist. Campbell
Genetics hold far more sway over the mouse microbiome than transient environmental exposures, researchers reported July 26 in Applied and Environmental Microbiology. The results appear

Antibiotics are known to influence the growth of bacteria in the human body. But new research led by a team at the European Molecular Biology
Tracking 265 people’s various microbial communities, researchers have provided a wealth of data on microbiome variation across the body and over time. As part of
Plaques of amyloid-β peptides in certain parts of the brain are a telltale sign of Alzheimer’s disease–associated neurodegeneration. When not in pathological aggregates, these peptides—found
The evidence continues to mount over the importance of the human microbiome—especially within the intestinal tract—for supporting optimal growth and overall health and wellness. Over
Diabetics who use the commonly prescribed drug metformin to control blood sugar levels have a different composition of gut microbiota than other diabetics, according to
When animals eat, gut bacteria numbers spike. It also appears that the organisms have a means of limiting growth: by sending signals to their host
T cell infiltration of solid tumors is associated with favorable patient outcomes, yet the mechanisms underlying variable immune responses between individuals are not well understood.
