...heavily influenced by your particular genes. But scientists have long known that these three factors do not adequately explain every case of obesity, and now researchers are discovering increasingly convincing evidence of another important contributor to body weight, one that until recently has been almost completely ignored: the bacteria that live in your...
...study builds on previous research in mice that suggests that heavy bodies may have a different makeup of gut bugs than thin ones. The gut microbiota of obese mice has been shown to have significantly more of one main type of bacteria called Firmicutes and fewer of another kind called Bacteroidetes (both types populate human guts as well); in normal mice, the distribution is the opposite. Jeffrey Gordon at Washington University in St. Louis, Mo., who conducted the previous research, experimented again with mice for the new paper. This time, however, he and his team used human microbiota to colonize...
Researchers started with mice that were specially bred to be germ-free - with no gut microbiota of their own - and to be able to nurture human gut microbiota. Researchers injected the mice with samples of fresh and frozen human feces, the bacteria from which took hold and colonized in the gut of the mice. If that surprises you, it absolutely stunned the researchers. "We were surprised that so much of the diversity present in human microbial communities could be recaptured in mice," says Gordon, who has been studying gut microbiota for more than five years...
Sunday’s opening celebration for The Laboratory will feature exhibitions by current Harvard undergraduates, ranging from a new way to transport water to a program that translates heart beats into music to a way of making electricity from bacteria in dirt...
Mabel P. Duyao, director of research at the HMS Pathology Department, said that sodium azide is used in laboratories—including the 8th floor pathology lab at the New Research Building—to protect solutions from bacteria and other microorganisms...
