A study uncovers connections between the bacteria in our guts and our social lives.

Physical activity, independent of diet, shifts the composition of bacteria in the intestines, spurring researchers to search for species that might provide benefits akin to working out.

The Purdue University nutrition researcher delves into the details of how fat tissue affects tumors.

Calories aren’t enough to correct malnourishment, but eating foods that spur specific microbes to grow in the gut can.

Two new techniques allow researchers to manipulate the activity of gut bacteria. 

Precursor T cells bearing the same antigen receptor adopt two different fates in mice.

In mice lacking intestinal microbiota, white fat turns brown and obesity is prevented.

Factors that likely contribute to obesity include disruptions to intercellular signaling, increased inflammation, and changes to the gut microbiome.

Extreme diets can alter the microbial makeup of the human GI tract, and change the behavior of those bacteria.

Chilly mice develop more tumors; gut bacteria aid cancer treatment; two Y chromosome genes sufficient for assisted reproduction; HIV’s “invisibility cloak”

Mice on a low-calorie diet harbor a distinct population of gut microorganisms that helps prolong life.

Viruses that attack bacteria may be an important component of our gut microbiota.
