A study sheds new light on the connection between the gut and the brain, untangling the complex interplay that allows the byproducts of microorganisms living in the gut to influence the progression of neurodegenerative diseases.
The level of diversity of the ‘good bacteria’ in our digestive systems has been found to be linked to a feature of cardiovascular disease — hardening of the arteries — in new research.

Bacteria found in the small intestines of mice and humans can travel to other organs and trigger an autoimmune response, according to a new study. The researchers also found that the autoimmune reaction can be suppressed with an antibiotic or vaccine designed to target the bacteria, they said.
Some microbiome researchers had suggested that this variation begins with differences in our genes; but a large-scale study challenges this idea and provides evidence that the connection between microbiome and health may be even more important than we thought.
Exposure to psychological stress in the form of social conflict alters gut bacteria in Syrian hamsters, according to a new study.
