OpinionMaybe Vitamin C isn’t just expensive urine after all
“Expensive urine” has become a convenient way of dismissing vitamin supplements taken in doses beyond what our bodies have an immediate need for. But if some unabsorbed vitamin C remains in the gastrointestinal tract, it raises an interesting question about how it could be interacting with the gut microbiome.

NewsIndustrialisation may be reshaping the evolution of our gut bacteria
Gut bacteria living in industrialised societies appear to be evolving differently from those in non-industrialised populations. Researchers found that strains from industrialised hosts had recently acquired more genes, mostly through horizontal gene transfer, suggesting that modern lifestyles may be reshaping microbial evolution inside us.

NewsBreast milk sugar may help protect newborns from jaundice
A sugar naturally found in breast milk may help newborn intestines mature and process bilirubin, the compound that builds up during jaundice. In mice, loss of 3’-sialyllactose disrupted gut development, worsened hyperbilirubinemia and was linked to greater intestinal vulnerability later in life.

NewsCattle genetics and gut microbes could help cut methane emissions
Researchers are uncovering how cattle genetics and rumen microbes work together to shape methane emissions and feed efficiency. The findings could support new feed additives, probiotics and microbial strategies that reduce emissions while helping cattle extract more energy from their diet.

NewsResearchers harness the microbiome to prevent deadly bloodstream infections
Researchers have pioneered a new approach to preventing dangerous bloodstream infections in patients receiving donor stem cell transplants for blood cancers. The first-of-its-kind therapy delivers 16 carefully selected beneficial bacteria designed to restore the microbiome and fight harmful pathogens.

NewsEnzyme found to have surprising role in earliest infant gut microbiome development
Microbiologists have found that an enzyme, not normally associated with microbial activities in the human gut, to have a role in how some bacteria access key nutrients in breast milk. The findings, published in Nature Communications today (Monday 2 November), provides a new understanding about feeding preferences ...

NewsFunctional food microecology links gut microbes to One Health
A new review proposes the framework Functional Food Microecology (FFM) that connects functional foods, the gut microbiome and host health. Rather than viewing diet only as calories and nutrients, the authors described food components as signals that gut microbes can transform into bioactive molecules.

NewsCan the microbiome really change medicine? Scientists confront the evidence gap
At Targeting Microbiota 2026 in Málaga, international scientists will explore how microbiome discoveries can move beyond laboratory research toward evidence-based clinical applications.

NewsDiscovery in gut microbiome of vegans surprises researcher
A study investigated the gut microbiome of 75 vegans and 75 omnivorous Danes. The researchers initially expected the vegan group to have the healthiest gut microbiome across all parameters, but found one notable weakness: gut bacterial diversity was, on average, lower among vegans than among omnivores.

NewsGut bacteria emerge as potential targets after spinal cord injury
Spinal cord injury may reshape the gut microbiome in ways that influence inflammation, weight loss and muscle-related metabolism. Researchers have built a genome-level catalogue of gut microbes after injury and identified bacterial species that could become targets for future microbiome-based treatments.

News40-year mystery solved: Common gut virus infects bacteria, not human cells
Ever since one denizen of the gut microbiome, known as picobirnavirus, was first spotted decades ago, researchers thought it directly infected human tissue and played a role in gastrointestinal illness. But researchers have just rewritten that story: This widespread virus infects gut bacteria, not human cells.

NewsGene-regulatory pathway helps T cells tolerate gut bacteria and prevent inflammation
The immune system somehow tolerates trillions of gut bacteria without constantly attacking them. Researchers have now identified a gene-regulatory pathway that helps regulatory T cells maintain this peace, with defects in the pathway triggering severe inflammation and autoimmunity in mice.

NewsScientists propose national microbiome plan to prevent chronic disease
Leading microbiome researchers are calling for a global ‘moonshot’ to determine how the microbes living in and on our bodies contribute to chronic disease. The proposed agenda would combine long-term human studies, clinical trials, global research standards and public education to move the field from promising associations towards proven causes and treatments.

NewsGut microbiome may help explain why sleep improvement varies after hydrogen supplementation
Hiroshima University researchers investigated the effects of hydrogen supplementation on sleep quality in healthy human volunteers. While hydrogen supplementation had no significant effect compared to a placebo, individuals in the hydrogen-supplementation group reporting better sleep quality were discovered to have a lower abundance of hydrogen producing bacteria in their gut microbiome.

NewsTargeting the gut-liver axis: New review explores microbial modulation to enhance immunotherapy in hepatocellular carcinoma
A review examines how gut microbiota and their metabolites reshape the hepatic immune microenvironment through the gut–liver axis, influence immune checkpoint inhibitor efficacy, and explore emerging combination strategies, including fecal microbiota transplantation, probiotics, engineered bacteria, and metabolite-based interventions.

NewsCan better gut health help patients with ovarian cancer tolerate chemotherapy?
A new clinical trial is testing whether probiotics can help patients with ovarian cancer better tolerate chemotherapy. The trial will look at whether probiotics can help reduce treatment side effects and improve quality of life. Researchers will also study how changes in the gut microbiome may be linked to treatment response.

NewsGut-inspired biobattery uses bacteria to generate electricity
The tiny finger-like structures lining our small intestine have inspired a new design for bacteria-powered batteries. By mimicking intestinal villi, researchers created a bioelectrode with more surface area and better nutrient flow, allowing bacteria to generate stable electricity for hours.

NewsAntibiotic use from childhood linked to higher odds of IBS in young adulthood
Antibiotic use from childhood through early adulthood was associated with higher odds of irritable bowel syndrome (IBS) at age 24, with the odds increasing as the number of antibiotic prescriptions rose, according to a new study.

NewsGut microbes don’t just train the immune system—they keep it in shape
Immune maturation has long been viewed as a developmental milestone tied to weaning, when pups are first exposed to a flood of dietary antigens and colonizing microbes. A study now suggests that in mice, the immune competence established after weaning is not self-sustaining—it must be continuously maintained by signals from the commensal microbiota.

NewsHow E. coli eavesdrops and senses Bifidobacterium
Gut bacteria may be quietly listening in on one another’s metabolism. Researchers have discovered that E. coli can detect chemical signals released by Bifidobacterium, allowing it to sense what nearby bacteria are doing and adjust its own metabolism in response.
