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.
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.
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.
Fecal transplants work, but they come with real drawbacks: donor variability, pathogen risk, and no easy way to scale. A new Mount Sinai trial suggests a precisely engineered 15-strain bacterial therapy could change that.
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.
A new genetic study has traced a causal path from specific gut microbes to liver cancer, using chromosomal inheritance patterns to cut through the noise of diet, lifestyle, and reverse causation.
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.
