NewsGut microbiome affects alcohol preference by influencing brain’s reward system
A new study shows how an overgrowth of Candida albicans - overly abundant in people with alcohol use disorder - increases levels of inflammatory molecules that can cross the blood-brain barrier and affect the desire for alcohol.

NewsAfrican wildlife poop sheds light on what shapes the gut ecosystem
A study of elephants, giraffes and other wildlife in Namibia’s Etosha National Park underscores the ways in which the environment, biological sex, and anatomical distinctions can drive variation in the gut microbiomes across plant-eating species.

NewsA triple-threat iron supplement that also improves gut health
A new iron supplement combines iron, prebiotics and probiotics. In trials, the treatment successfully restored blood iron levels in anemic mice without initiating an inflammatory response or throwing off the balance of the gut microbiota.

NewsBiologist links stable gut bacteria to healthy childhood growth
New research reveals that the stability of gut bacteria in early life plays a critical role in whether children thrive or struggle with undernutrition – a global health challenge affecting millions.
-
NewsDiscovery of hundreds of new human gut viruses provides a new approach to studying the gut microbiome
Hundreds of new viruses living inside bacteria within our gut have been discovered in an international study. These bacteriophages could eventually be used to reshape the gut microbiome, potentially influencing gut health and the progression of various disease states.

NewsGut microbiota disruption predicts severe steatosis in MASLD patients
A new study links gut dysbiosis with severe steatosis in metabolic dysfunction–associated steatotic liver disease (MASLD). In a 61-patient cohort, those with the inflammation-linked Bact2 enterotype developed severe steatosis at lower thresholds.

NewsValorization of soybean-processing wastewater sludge via black soldier fly larvae: performance and bacterial community dynamics
A new study indicates that the valorization of soybean-processing-sourced sludge via black soldier fly larvae was achieved via functionally important BSFL intestinal microbiota, providing an efficient recycling approach for similar waste streams.

NewsScientists reveal role of paeoniflorin in mediating microbiota-gut-brain axis
Paeoniflorin treatment significantly reduced depression-like behaviours in stressed rats, while gut microbiota analysis revealed that the treatment corrected imbalances in key metabolites associated with brain function, a study shows.

NewsPioneering gut health testing with a simple finger prick
Zinzino, the Scandinavian health and wellness company, has announced the launch of its innovative Gut Health Test. With a simple at-home finger prick, this is the first commercial test to measure what gut bacteria produce and how the body responds.
-
NewsSped-up evolution may help bacteria take hold in gut microbiome
A genetic mechanism inserts mutations into key DNA hotspots that enable bacteria to adapt to new environments, a new study finds.
-
NewsMolecular bodyguard helps infections persist
Researchers have identified a key molecular player that helps bacteria survive the hostile environment inside the body. Their study reveals how the protein RfaH acts as a protective shield for bacterial genes — and points to new strategies for fighting persistent infections.
-
NewsHow microbial strain variations influence neurobehavior
Microbial single nucleotide variations influence host cognitive behavior by regulating metabolism, a new study of merino sheep reveals.
-
NewsMore than a feeling: Could a healthier gut improve mental health?
A new review finds strong causal evidence that gut microbes can change brain chemistry, stress responses and behaviours in animal models; and evidence that probiotics, diet changes, and faecal microbiota transplants improve mood and anxiety.

News1,000-year-old gut microbiome revealed for young man who lived in pre-Hispanic Mexico
Analysis of preserved feces and intestinal tissue has revealed specific types of bacteria that were present in the microbiome of a young adult man who lived in Mexico about 1,000 years ago, prior to Spanish colonization.

NewsMicrobiome and nanoparticle discoveries hold promise for treating gut pain
In an effort to develop targeted treatments for gut pain, scientists have discovered a new enzyme in gut bacteria and are using nanoparticles to deliver drugs inside cells. PAR2, a receptor involved in pain signaling, is activated by certain enzymes called proteases.
-
NewsChanges in gut microbiota influence which patients get AIG-related neuroendocrine tumors
Researchers have discovered how the balance of bacteria in the stomach affects the growth of neuroendocrine tumors (NETs). By identifying the specific bacteria involved and the biochemical reactions that cause tumor growth, they hope to detect which patients are most likely to develop cancer.

NewsMitochondria & microbiota: Targeting Extracellular Vesicles 2025 to explore game-changing pathways in medicine
The Second World Congress on Targeting Extracellular Vesicles (EVs) is scheduled for 15–16 October 2025 in Valencia, Spain. This event will spotlight the rapidly evolving science where mitochondrial biology and microbiome research intersect via extracellular vesicles.

News‘Good’ gut bacteria boost placenta for healthier pregnancy
Research has found the first clear evidence that the ‘good’ gut bacteria Bifidobacterium breve in pregnant mothers regulates the placenta’s production of hormones critical for a healthy pregnancy. Pregnant mice without Bifidobacterium breve in their gut had a higher rate of complications, and increased fetal loss.

NewsMicroplastics found to change gut microbiome in first human-sample study
New research presented today at UEG Week 2025 shows that microplastics can alter the human gut microbiome, with some changes resembling patterns linked to depression and colorectal cancer.

NewsNew antibiotic targets IBD — and AI predicted how it would work before scientists could prove it
The new antibiotic, enterololin, attacks and kills only a specific group of disease-causing bugs, which includes the type of E. coli that drives Crohn’s disease. It is a promising new treatment option for people affected by Crohn’s and other IBD-related conditions.
