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 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.
Shedding abdominal fat through diet and exercise leaves a lasting imprint on your metabolic health, even if the weight comes back. A decade-long study tracked what happens inside the body long after the diet ends.
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.
Millions take antidepressants that boost serotonin to quiet depression and anxiety, yet many report their ear ringing gets louder. Now researchers have found the exact brain circuit responsible.
The molecules your gut bacteria produce from fiber are not interchangeable: a new RNA-sequencing study finds that butyrate, propionate, valproate, acetate, and 3-hydroxybutyrate each flip different genetic switches inside colorectal cancer cells.
Your mouth and colon are in constant microbial conversation, and a new review suggests that conversation can turn deadly when oral bacteria like Peptostreptococcus hitch a ride to the gut.
Beneath every intensively farmed field, a quiet extinction is unfolding. Rare soil microbes, the unseen guardians of nutrient cycling and ecosystem resilience, are being wiped out by the same practices that maximize crop yields.
Between 2016 and 2021, candida infections among diabetic patients at a Saudi hospital increased by a staggering 54-fold. New research pinpoints exactly which lab values predict who is most at risk.
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.
