Five millennia after his death, Ötzi the Iceman is still hosting living microbes. Scientists have now cultured four cold-adapted yeasts from his mummy, some bearing signs of ancient DNA damage that trace them back to Copper Age colonizers.
The selenium on your food label may not be the selenium your body actually gets. A new study shows gut microbes intercept, transform, and redirect this essential mineral before your cells ever see it.
What if your gut bacteria could quietly siphon off 116 calories a day before your body ever absorbs them? A tightly controlled clinical trial just measured exactly that.
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.
Most microbiome tests tell you who's living in your gut, not what they're actually doing. A new oral tyrosine challenge test aims to change that by measuring the metabolic output of gut bacteria in real time.
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.
Decades of diet wars pitted low-carb against low-fat, but a sweeping new study tracked nearly 200,000 Americans for over 30 years and found the real driver of heart health is neither camp: it's the quality of what you eat.
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.
Long before birth, a mother's microbial communities are already negotiating the terms of her child's immune system, metabolism, and brain development. A sweeping new review reframes pregnancy itself as an ecological event.
A large citizen-science platform in Belgium just mapped the comorbidity landscape of endometriosis in striking detail, and delivered a surprise: the vaginal microbiome looked essentially the same as in women without the condition.
