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.
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.
Shift work, irregular meals, and disrupted sleep do more than make you tired: they may be quietly dismantling the gut defenses that keep Crohn's disease and ulcerative colitis at bay.
Immune checkpoint drugs have transformed cancer care, but most patients still don't respond. A sweeping new review in Cell Metabolism argues the gut microbiome is a central reason why, and a potential lever to change that.
A gut bacterium best known for reinforcing the intestinal lining may also be one of the most powerful natural shields against fatty liver disease - and scientists now have a detailed map of how it works.
The bacteria living in your gut are not passive passengers. A sweeping new review finds they actively shape your blood pressure by churning out metabolites that reach your arteries, immune cells, and hormonal systems.
When liver cancer stops responding to immunotherapy, the gut microbiome may hold the key to restarting it. A small but striking clinical trial found that transplanting stool from immunotherapy-responsive donors restored tumor control in nearly half of patients who had run out of options.
A single bacterial gene in your gut may be quietly tipping the scales between tumor growth and immune defense, and the molecule at the center of the fight is an amino acid most people have never heard of.
Trillions of gut bacteria quietly regulate your heart health through metabolites, inflammation, and platelet activity. A sweeping new review spells out exactly how dysbiosis drives cardiovascular disease and what science is doing about it.
Once dismissed as a fringe remedy, fecal microbiota transplantation has quietly become one of the most versatile tools in modern medicine, moving from treating stubborn gut infections to rewiring immune responses in cancer patients.
