Chronic stress floods the body with cortisol, but new research suggests the gut holds an unexpected buffer. Scientists found that commensal gut bacteria can dampen the brain-damaging effects of corticosterone and ease depressive-like behavior in an animal model.
A plant compound found in seeds, grains, and vegetables may fight depression by rebalancing the microbial communities that talk directly to the brain. New multi-omics research maps exactly how.
The gut may betray signs of Alzheimer's disease long before a clinical diagnosis arrives. New research finds that people with mild cognitive impairment already carry gut microbiome signatures strikingly similar to those in full Alzheimer's.
A natural compound found in everyday foods like lentils, nuts, and whole grains may do far more than sit quietly in your diet. New research shows it can activate a key epigenetic enzyme that keeps the gut barrier intact.
Nearly all of the body's serotonin is made in the gut, not the brain, and a landmark Caltech study identified exactly which bacteria are responsible. The findings could reshape how we treat conditions from irritable bowel syndrome to cardiovascular disease.
Your gut bacteria don't just digest food; they also reactivate sex hormones that tell your intestines how fast to move. A new study in Nature Neuroscience reveals the precise enzymatic mechanism behind this surprising circuit.
Two bacteria acquired in the first year of life appear to dampen the risk of autism and ADHD in babies already predisposed by their epigenetic profile at birth. A new study from nearly 1,000 families suggests that conversation between genes and gut may start at the moment of delivery.
Eating at irregular times does more than disrupt your schedule. A large Korean study found it raises the odds of depression by 55%, with breakfast skipping and monotonous diets compounding the harm considerably.
Before a single memory slips, the gut may already be sending distress signals. A new preprint study finds that older women carrying the APOE ε4 gene show the sharpest decline in butyrate-producing bacteria, a pattern that could prime the brain for Alzheimer's.
A disrupted gut microbiome can reprogram bile acid chemistry and flood breast tissue with inflammatory immune cells, accelerating tumor spread to the lungs and lymph nodes in hormone receptor-positive breast cancer.
