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.

NewsNew insights into how pathogens build protein machinery for survival in the gut
New research reveals how pathogenic bacteria construct tiny protein-based compartments, known as Eut microcompartments, which enable them to digest ethanolamine - a nutrient commonly found in the gut.
-
NewsSummer studentship: Eoin probes medicine-microbiome interactions using in vitro gut model
Eoin McKernan reports back on his AMI-sponsored summer studentship which focused on the relationships between the gut microbiome and the metabolism of variable response drugs.
-
OpinionKey lessons from the saMBA studies on human gut microbiome diversity
A recent study published in Nature Communications introduced the South American MicroBiome Archive (saMBA). The study offers several critical insights that deserve careful consideration.
-
NewsHow the gut microbiome helps Japanese macaques eat with the seasons
A study shows that both the composition and fermentative ability of the Japanese macaque gut microbiome shift flexibly across seasons, while the latter in particular increased during the harsh winter when macaques relied on leaves.
-
NewsVast gut microbiome diversity and antibiotic resistome across 14 mammal species on the Tibetan Plateau
A new study provides the most comprehensive genomic catalogue to date of mammalian gut microbiomes from the Tibetan Plateau.
-
NewsChristensenella tenuis inhibits gut-derived endotoxins to alleviate metabolic disorders
The gut probiotic Christensenella tenuis significantly alleviates endotoxemia and metabolic disorders by modulating gut bile acids (BAs) metabolism and suppressing lipopolysaccharide (LPS) translocation across the gut barrier, a new study finds.
-
NewsSugary drinks influence the psyche via the intestine
A new study provides strong evidence that sugary drinks affect not only metabolic but also mental health – especially in women. This effect is probably mediated by the sensitive microbiome of the intestine.
-
NewsMilk matters: How donor human milk storage affects preemie gut health
A study reveals that shorter storage durations of donor human milk are linked to reduced gastrointestinal complicatoins in premature infants, including necrotizing enterocolitis. These findings suggest that minimizing milk storage time may help to preserve protective properties crucial for preterm gut health.

NewsKey to the riddle of sleep may be linked to bacteria
New research suggests a new paradigm in understanding sleep, demonstrating that a substance in the mesh-like walls of bacteria, known as peptidoglycan, is naturally present in the brains of mice and closely aligned with the sleep cycle.
