In a study involving data from thousands of people, the risk of a new coronary heart disease diagnosis was statistically associated with bloodstream levels of nine specific molecules that are produced ...

Scientists at MIT have discovered that a little-known protein called intelectin-2 plays a powerful double role in defending the gut. The protein strengthens the mucus layer that lines the ...

Researchers at Case Western Reserve University found evidence that gut bacteria may contribute to brain damage in Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD). Their study ...

The "hygiene hypothesis" suggests exposure to diverse types of microbes may protect against developing diseases caused by allergens, but a new study in mice reveals that adults' exposure to diverse ...

Scientists discover immune genes influence which gut bacteria live in animals by studying a tiny island bird population.

A high-fat diet can cause the intestinal lining to weaken, allowing live gut bacteria to travel directly to the brain in mice ...

Scientists have created a genomic blueprint for Aeromonas bacteria, which can cause antibiotic-resistant diarrheal disease—with symptoms often misidentified as cholera—in humans and animals.

Extremophiles may well be tiny, but they are making a huge contribution to the health of our planet and our lives. A new review of these microorganisms, published in the journal Frontiers in ...

Scientists at Arizona State University have uncovered surprising new ways bacteria move, even without their usual whip-like propellers called flagella. In one study, E. coli and salmonella were found ...

Most people think of brushing and flossing as a way to keep their teeth looking good. But emerging research suggests that ...

Scientists have engineered a common probiotic bacterium to act like a microscopic drug factory that hunts down tumors and delivers cancer-killing compounds directly where they’re needed. Credit: ...
