NewsThe gut can drive age-associated memory loss
Scientists have discovered that the aging gastrointestinal tract produces specific molecules that blunt the activity of a key gut-brain neuronal pathway, leading to age-related cognitive decline in mice.

NewsIsland birds reveal surprising link between immunity and gut bacteria
Scientists have uncovered a hidden link between gut health and the immune system, all thanks to a tiny island bird. They collected the poo of the Seychelles warbler to analyse their gut bacteria – and found that their immune genes influence which gut microbes thrive.

NewsAntibiotics can affect the gut microbiome for several years
Researchers have found strong links between a person’s history of antibiotic use and the composition of their gut microbiome, including the diversity of bacterial species.

NewsSpecific gut bacteria species linked to muscle strength
A species of gut bacteria called Roseburia inulinivorans is specifically associated with human muscle strength and improved muscular performance in mice, finds new research. R inulinivorans changes certain metabolic processes in muscle, and converts muscle fibres to ‘fast-twitch’ (type II).

NewsGut bacteria drive process that protects colon tissue
Researchers have shown that the identity of distinct regions of the colon are regulated by the gut microbiome. They identified nicotinic acid, a molecule produced by certain bacteria in the gut microbiome, as a main driver of these regional differences in the colon’s sections.

NewsStay or stray? Scientists discover why some gut microbes persist after fecal transplants
Scientists have identified why some gut microbes successfully stay in the gut after faecal transplants, whilst others are much more transient. They tracked key genetic features of gut bacteria in 86 healthy adults over the course of a year.

NewsEnteroBiotix announces completion of enrolment in Phase 2a Trial evaluating EBX-102-02 prior to allogeneic stem cell transplantation
EnteroBiotix announced that the investigator-initiated Phase 2a MAST trial has completed its enrolment of 50 adult patients undergoing allogeneic haematopoietic stem cell transplantation (allo-HSCT) for defined haematological malignancies.

NewsWhen rats run, their gut bacteria rewrite the chemical conversation with the brain
A new study suggests that exercise stimulates a molecular link between gut bacteria and the brain. The research examined what happens to the gut microbiota, circulating metabolites, and hippocampal gene expression when rats are given free access to a running wheel for eight weeks.

NewsResearchers make probiotic safer for immunocompromised patients
Researchers have modified a probiotic yeast to make it safer for use by immunocompromised people, older adults and infants. Testing in an animal model found the modified yeast is less likely to cause infection than unmodified strains of the same organism.

NewsStudy highlights gut–brain axis in pituitary tumor–related cognitive decline
Researchers conducted a prospective cross-sectional study to evaluate cognitive function in patients with pituitary neuroendocrine tumors and examine associations among tumor lineage, hormonal abnormalities, and gut microbiota composition.
-
NewsGut microbes rewrite the rules of cancer immunotherapy
A review synthesizes growing evidence showing that commensal microbes enhance anti-tumor immunity by producing immune-active metabolites, remodeling the tumor microenvironment, and activating key immune cells such as dendritic cells and cytotoxic T cells.

NewsNew studies reveal how Clostridioides difficile behaves inside the body
Researchers studying C. diff at multiple levels, from how individual bacterial cells behave inside the gut to the molecular switches that help them survive and spread, are revealing hidden vulnerabilities.
-
NewsDiversification of termite diets was made possible by genome modifications
Study reveals that evolutionary divergence occurred before ecological divergence, enabling these insects to feed on both wood and soil. Future discoveries may be applied to the production of biofuels.
-
NewsNew compound stops common complications after intestinal surgery
Researchers have synthesized and tested a new compound in mice that shows promise in protecting the liver from damage and improving nutrient absorption after small bowel resection. They also found that the drug works only on the gastrointestinal tract.

NewsStudy reveals how gut bacteria and diet can reprogram fat to burn more energy
A new study shows that a low‑protein diet activates a precise set of gut microbes that send chemical signals throughout the body, prompting fat tissue to burn energy instead of storing it. The findings uncover a previously unknown biological pathway linking diet, the gut microbiome and metabolic health.
-
NewsFrom gut to lung: A microbial signal that strengthens early immune defense
Researchers report that a gut microbiota–derived metabolite can directly shape immune responses in bacterial pneumonia. Using a Klebsiella pneumoniae infection model, the team demonstrated that butyric acid restores the function of CX3CR1-positive natural killer cells.

NewsHow periodontitis-linked bacteria accelerate osteoporosis-like bone loss through the gut
Researchers reveal that salivary bacteria from gum disease alter gut metabolism, driving osteoclast activity and systemic bone loss. They analyzed salivary microbiota from individuals with advanced periodontitis and compared them with samples from periodontally healthy donors.
-
NewsGut microbiome connected with heart disease precursor
Before the onset of cardiovascular disease symptoms, people often develop dyslipidemia, or abnormal levels of lipids in the blood. Microbiologists have identified microbial taxa more likely to be found in people with dyslipidemia than in people with healthy levels of cholesterol and triglycerides.

NewsTargeting the gut–lung microbiome to reduce infections in severe pancreatitis
Researchers report new clinical evidence that a fungal probiotic may reduce hospital-acquired infections in patients with severe acute pancreatitis. Patients receiving Saccharomyces boulardii alongside standard enteral nutrition experienced significantly fewer infections than those receiving nutrition alone.

NewsBacteria found in mouth and gut may help protect against severe peanut allergic reactions
One of the big mysteries in food allergy is why two people with similar levels of peanut specific antibodies can react so differently. A new study shows for the first time how gut bacteria break down parts of an allergenic food and influence how a person reacts to peanuts.
