NewsStudy finds Helicobacter pylori exposure may be associated with more than one in five colorectal cancer cases worldwide
An international collaborative research study has found that exposure to Helicobacter pylori, a bacterium known to cause stomach ulcers and gastric cancer, may be associated with approximately 22% of colorectal cancer cases globally.

NewsResearchers explore link between gut, brain health for people with HIV
Oregon Health & Science University researchers have secured a $5.8 million, five-year federal award to investigate whether damage to the gastrointestinal tract contributes to neuroinflammation in people living with HIV — raising the potential for new treatments to preserve brain function in people with HIV and older adults.

NewsA natural compound takes aim at C. difficile while sparing the gut microbiome
Researchers identify argyrin B, a promising natural compound that targets the bacterium behind dangerous intestinal infections while leaving beneficial gut microbes largely unharmed. The discovery could pave the way for new treatments with fewer relapses and side effects.

NewsBeetles build with a yellow pigment gene
More than 80 years ago scientists discovered that differences in yellow pigmentation were critical to courtship success and failure for fruit flies. New research has added a deeper perspective to the study of Yellow, showing how in tortoise beetles this protein has been co-opted as a building material to house symbiotic bacteria.

NewsGut microbes across continents trace ancient human migration
A new study has attempted to answer the question of whether homo sapiens hosted a characteristic and diverse microbiome going back millennia. Gaining insight into which, if any, long-term residents of the microbiome co-evolved with humans could point to ways to investigate how the loss of microbial diversity through industrialization impacts human biology.

NewsStudy may explain why IBD patients react to foods they once tolerated
A new study finds that gut inflammation can change the way gut bacteria break down food — possibly triggering immune reactions to foods that were previously fine to eat. The findings may help explain why so many people with inflammatory bowel disease (IBD) react badly to foods like dairy or gluten, even in remission.

NewsGut bacteria shape how fiber works
Eating more fiber does not necessarily mean the same thing for every gut microbiome. New research shows that plant-based carbohydrates can favor Segatella copri only when certain other bacteria are already present, revealing how strongly diet depends on the microbial community it enters.

NewsModel traces C. diff spread in hospital oncology units
In a new study, researchers modeled the transmission of Clostridioides difficile infections among patients in hospital cancer units. They found that most new infections were introduced by patients who were infected but not symptomatic at the time of admission, rather than by patients who were infected and symptomatic.

NewsHow gut bacteria can shape the brain’s response to stroke
How much damage a stroke causes in the brain depends strongly on how quickly blood flow can be restored. The patient’s own immune response that follows the stroke also plays an important role. Researchers have identified a specific bacterial signal that shapes this immune response and influences stroke outcome.

NewsSugar amplifies damage done to gut health by antibiotics
Eating sweets while taking antibiotics may worsen the harm done by the drugs to the normal community of bacteria in the gut, a new study has found. The study of hospitalized cancer patients found an additional 21% reduction in the variety of helpful bacterial species present for every 100 grams of sugar consumed in the 48 hours before treatment.

NewsBlueberries modify gut microbiome in older adults with mild depression
A new pilot study has found that older, sedentary adults who consumed blueberries daily showed a greater, more consistent reduction in depressive symptoms, paired with minor changes in markers of gut microbial enzymes.

NewsGut enzyme links microbiota, barrier dysfunction and MASH progression
Metabolic dysfunction-associated steatohepatitis (MASH) is often viewed through the lens of hepatic lipid accumulation, inflammation and fibrosis. A new study identifies intestinal neutral ceramidase as a gut-derived driver of MASH progression through its effects on microbial metabolism, epithelial signalling and intestinal barrier function.

News Distinct gut microbiome patterns found in 5 cancer groups and in early-onset cancers
Researchers have discovered distinct gut microbiome patterns in adults 50 or younger with colorectal and breast cancers compared with those diagnosed later in life — one of several findings from an analysis of stool samples from 1,364 patients with cancer across cancer types, stages and treatments.

NewsGut microbiome emerges as a potential partner in precision cancer therapy
A new editorial examines how the human microbiome may influence cancer development, treatment response and emerging precision-oncology strategies.

NewsResearchers develop AI tool that reveals hidden clues in the gut microbiome
Researchers are using artificial intelligence to uncover hidden clues among the trillions of bacteria living in the human gut, including changes that could one day help scientists detect diseases earlier.

NewsGut microbiome can reveal risk of type 2 diabetes
Changes in the composition of bacteria in the gut could provide early warning of type 2 diabetes (T2D), new research has found. The analysis of data from hundreds of thousands of individuals identified hundreds of changes in the composition of the gut microbiome that can be detected before the onset of any changes in blood glucose measures.

NewsCould these pills help people with anorexia? A new study aims to find out
A new clinical trial is recruiting people diagnosed with anorexia nervosa as researchers hope to discover if fecal microbiota transplant (FMT) capsules could help better manage this eating disorder.

NewsGut microbiome development may help predict type 1 diabetes in children at high risk
A new prospective study found that children at high genetic risk of type 1 diabetes whose gut microbiome development plateaued early had about three times the risk of developing the disease compared with children whose microbiomes continued to mature.

NewsA tiny bacterium with a huge impact
Researchers have discovered that gut bacteria and the compounds they produce trigger biological processes that the human body on its own can only activate with difficulty. They help suppress inflammation and may also have beneficial effects on fatty liver disease.

NewsOral chiral nanozyme protects the heart during chemotherapy by reshaping the gut-heart axis
A chirality-engineered nanozyme restores gut microbiota and host metabolism to prevent doxorubicin-induced cardiotoxicity without compromising anticancer efficacy.
