Researchers tracked gut microbiome changes in 335 remote Amazonian Indigenous people over four months of routine medical treatment, and found that diversity collapsed quickly, even without dietary or lifestyle changes.
Two people eat the same high-fiber meal, yet one absorbs measurably more calories than the other. New research points to a surprising culprit: methane-producing microbes living in the gut.
Genetic evidence now confirms that type 2 diabetes directly raises the risk of colon cancer, and a single gut bacterial species appears to carry part of that risk signal. The finding opens a new angle on prevention for the millions living with diabetes.
Scientists tracking more than 9,000 people have found that the healthiest older adults share a striking trait: their gut microbiomes keep drifting toward ever more unique compositions. Those who lose that drift may be losing years off their lives.
A urine test developed at Arizona State University can distinguish children with autism from typically developing peers with striking accuracy, by measuring metabolites produced by gut bacteria rather than analyzing genes or behavior.
Most microbiome studies only track what patients are taking right now. A sweeping new analysis suggests that approach misses something crucial: the drugs you stopped years ago may still be reshaping your gut.
