A disrupted gut microbiome does more than upset digestion. New research shows it can flood the body with bile acids that actively push hormone receptor-positive breast tumors to spread.
Researchers found that patients with atrial fibrillation carry far less Lactobacillus in their guts, and that a bacterial toxin called LPS may be the missing link between gut dysbiosis and an irregular heartbeat.
Your colon undergoes a slow molecular transformation as you age, and the warning signs are written in both your genes and your gut bacteria. A new integrative study of 238 human biopsies has mapped that transformation in unprecedented detail.
A gut bacterium thriving at high altitude can switch on the body's calorie-burning brown fat, cut white fat storage, and help mice stay warmer in the cold. The finding opens a surprising new angle on obesity treatment.
Eating more oats and chicory-derived fibers could do more than support digestion. A new study of people genetically predisposed to Crohn's disease links beta-glucan and inulin intake to meaningful protection against developing the condition.
A new study finds that PAH patients who harbor Lactobacillus in their gut tend to have less severe heart and lung damage, pointing toward the microbiome as an unexpected lever in a notoriously difficult disease.
The calorie counts on food labels have been calculated the same way for over a century, and they largely ignore your gut microbiome. A new model from Arizona State University just changed that math dramatically.
Maria Branyas Morera lived to 117 years and 168 days, surviving two world wars, the 1918 flu, and COVID-19. Now scientists have mapped her biology in unprecedented detail, and the picture is stranger than anyone expected.
Stomach cancer kills hundreds of thousands of people every year largely because it is almost always caught too late. A new blood test that reads microbial DNA circulating in plasma may change that calculus.
A new study tracks exactly how the infant gut transitions from breast milk to solid food, and the bacteria that thrive are the ones that can digest both at once.
