NewsSugar-free diets may disrupt gut microbiome
Eliminating sugar from your diet may be more detrimental than previously thought, according to an animal study. Mice fed a sucrose-free diet developed impaired glucose control, insulin resistance, gut microbial imbalance, intestinal inflammation and fatty liver changes, despite having no significant differences in body weight compared with control mice.

NewsGLP-1s may alleviate depression in mice through the microbiome
Some people taking GLP-1 drugs for diabetes and obesity experience mental health benefits. In a mouse model study, researchers report that these improvements appear to result from gut microbiome changes that lead to an abundance of a microbe strain known to have a favorable effect on neurons related to stress.

NewsExpert tips: Why it’s best to eat more than one kind of fiber - and build up gradually
Fiber is an essential part of a healthy diet. By eating a variety of plant-based foods, increasing fiber intake gradually and staying well hydrated, you can support gut health and overall well-being while making fiber goals more achievable and sustainable. Purna Kashyap, M.B.B.S., a gastroenterologist at Mayo Clinic in Rochester, ...

NewsFood insecurity linked to gut microbiome changes in children
A new study shows that food insecurity may leave a measurable impact on the gut microbiome of children. Children in food-insecure households had different gut microbiome profiles, including higher levels of Sutterella, which has been linked to poor dietary quality and intestinal inflammation.

NewsResearcher studying probiotics to fight acid reflux and esophageal cancer
Patients with acid reflux, which occurs when stomach acid pushes up into the esophagus, know the symptoms all too well: heartburn, belching, chest pain and trouble swallowing. Acid reflux also increases the risk of esophageal cancer, but researchers are investigating how a simple probiotic could treat and prevent both conditions.

NewsÖtzi and his microbiome: a 5,300-year-old relationship
Researchers have obtained a detailed picture of the microbial community associated with the Iceman mummy Ötzi. The study provides insights into a complex microbiome, ranging from the gut flora of a Copper Age human to cold-adapted yeasts.

NewsThe brain, emotions, and the gut: How culture, stress, and social life shape gut health
A new study indicates that gastrointestinal health is influenced not only by genes, diet, and gut bacteria, but also by culture, social relationships, economic status, and the way individuals function within society.

NewsScientists recreate enterovirus infection in a new model of the human intestine
A miniaturized, biomimetic model of the human intestine successfully reproduced long-term enterovirus A71 (EV-A71) infection, report researchers. Using this innovative platform, they shed light on how this virus grows in the intestine without triggering a strong immune response.

NewsEngineered gut bacteria therapy emerges as scalable potential alternative to fecal microbiota transplants following clinical trial
Researchers have developed a new manufacturing platform for producing targeted mixtures of beneficial gut bacteria, an approach that could help expand access to microbiome-based therapies for patients with recurrent Clostridioides difficile (C. difficile) infection.

NewsNew fluorescent nanosensor enables first-of-its-kind detection of key gut health biomarker
Researchers have developed a novel fluorescent nanosensor capable of rapidly detecting indole-3-propionic acid (IPA), an emerging biomarker linked to gut health and disease. The sensor produces a rapid optical readout within minutes, offering a significantly faster and more accessible alternative to conventional analytical techniques.

NewsProtection for newborns: New treatment aims to prevent meningitis without antibiotics
One of the leading pathogens responsible for meningitis cases in newborn babies is the K1 form of the E. coli bacterium. Now, researchers have developed a triple-pronged approach that seeks to prevent transmission to newborns.

NewsNew study suggests fish gut microbe helps regulate ocean health
New research reveals a potential link between the gut microbes of a fish and global ocean processes, offering new insight into how marine ecosystems help regulate ocean chemistry and the marine carbon cycle.

NewsScientists clarify the interplay between host and gut microbiota in selenium metabolism
In a recent study, researchers used rats to investigate how gut microbiota and the host jointly manage selenium metabolism. They found that gut microbiota actively transform selenium into various metabolites that influence selenium utilization, detoxification, and excretion, and that the host’s selenium intake affects bacterial diversity.

NewsOrangutans breastfeed their young for six and a half years, the longest among mammals
Researchers show that wild orangutan juveniles keep consuming their mother’s milk continuously until at least six and a half years of age. The study also suggests that the more milk a juvenile consumes, the stronger its biological defenses and the higher the presence of probiotic intestinal bacteria.

NewsNew model shows how gut microbes help shape how many calories you absorb from food
A new mathematical model follows food through the digestive tract, estimating what the body absorbs directly, what reaches the colon and how gut microbes help process the remaining material into products that are either absorbed or excreted.

NewsColorectal cancer risk linked to gut microbiome alterations
A study finds that more than a decade after removal of an adenoma from the colon, the gut microbiome still partly resembles that observed in colorectal cancer (CRC).

NewsGut microbe found to worsen sepsis by triggering hyperinflammatory immune responses
Researchers have identified a specific gut microbial group that can dramatically worsen sepsis by excessively sensitizing immune cells. Genetically identical mice showed strikingly different infection outcomes depending on the composition of their gut microbiota.

NewsGut microbiome clusters may help predict inflammatory bowel disease severity and progression
A new study reports that the gut microbiome of IBD patients can be grouped into distinct compositional “cluster types” associated with disease severity and progression risk. These reflect higher-order microbial community organization rather than variation in individual bacterial species.

NewsNew urine test for microbial metabolites offers simple way to screen for autism in children
Scientists have developed a new screening tool to test urine for 17 microbial metabolites in children ages 2 to 11 years. By measuring these compounds in urine, they discovered that they could distinguish children with autism from typically developing children in their study groups with high accuracy.

NewsInternational leaders in probiotic and prebiotic science to gather in Tokyo for one-day symposium
To help strengthen global collaboration and showcase innovative biotics research, The International Scientific Association for Probiotics and Prebiotics (ISAPP) is organizing a scientific symposium on October 6, 2026 in Tokyo, Japan in conjunction with its annual meeting.
