NewsGut microbiome changes may signal Parkinson’s disease risk
Scientists have found that people with Parkinson’s disease have a distinctive makeup of gut microbes, as do healthy individuals who are genetically at risk of Parkinson’s disease. This could help to develop tests to reveal a person’s risk of developing Parkinson’s disease.

NewsOral-gut axis points to salivary biomarkers for early gastric cancer detection
A recent study has identified distinct microbial “signatures” within the oral cavity and gut that serve as robust biomarkers for the early detection of gastric cancer (GC). Research shows how specific lactic acid-producing bacteria (LAB) migrate from the mouth to colonize the gastrointestinal tract.

NewsScientists probe how neurons sense bacteria in the gut
Neural interaction with bacteria, e.g. in the gut microbiome, has important effects on brains of animals from worms to people. A new study investigates how neurons sense bacteria by revealing, in nematodes, the bacterial signals that a key neuron detects.

NewsGut bacteria predict skin cancer recurrence, but only when matched for ‘microbial fingerprint’
The specific mix of bacteria living in a person’s gut can predict the chances that melanoma will recur after surgery and immunotherapy, which helps immune cells target cancer cells, according to a new study.

NewsSleep deprivation disrupts gut microbiota, worsening colorectal cancer outcomes
Researchers have found that the gut microbiota drives changes to the immune system caused by chronic sleep loss. These changes promote cancer progression, disrupt circadian rhythm and weaken the effectiveness of chemotherapy.

NewsAntibiotic resistance genes found in newborns within hours of birth, study shows
Antibiotic resistance genes can be present in newborns within the first hours of life. The study analysed meconium samples from 105 infants admitted to a neonatal intensive care unit (NICU) within the first 72 hours of life between July 2024 and July 2025.

News To thwart pathogens, researchers are giving beneficial microbes what they really want
Researchers have developed a new method that allows precise modification of any microbiome with prebiotics, helping beneficial organisms outcompete dangerous pathogens.

NewsScientists explore the bidirectional skin-brain axis: Mental health, dermatology-related quality of life, and the role of probiotics
Researchers investigating associations between mental health, dermatology-related quality of life (DLQI), and probiotic intake in 305 Brazilian adults found that women had significantly higher scores for anxiety, depression, and stress compared to men.

NewsHow gut bacteria and acute stress are linked
Researchers have demonstrated for the first time that, in healthy adults, the diversity of gut bacteria and their capacity to produce certain metabolites are associated with the acute stress response - particularly stress reactivity.

NewsGut microbiome serves as key driver for bacterial infection outcomes for fatty liver disease
Researchers found that metabolic dysfunction–associated steatotic liver disease dramatically worsens outcomes following infection with Vibrio vulnificus, a potentially life-threatening foodborne bacterium commonly associated with seafood consumption.

NewsFunctional traits, not phylogeny, drive gut microbial assembly in estuarine fish
By examining the gut microbiota of 61 sympatric fish species within the ecologically diverse Pearl River Estuary, researchers utilized this “natural laboratory” to disentangle complex biological drivers without the interference of geographical variation.

NewsExtracellular vesicle RNAs offer new hope for diagnosing and treating chronic inflammatory bowel disease
Extracellular vesicle-associated RNAs can serve as non-invasive biomarkers for early inflammatory bowel disease detection and disease monitoring, and also hold great potential as targets for next-generation targeted therapies, according to a new review.

NewsAutism and ADHD: Epigenetic changes at birth associated with an infant’s microbiome and neurodevelopment
Epigenetic changes present at birth can impact how an infant’s gut microbiome develops during their first year. Researchers also identified specific epigenetic changes and gut microbes that were associated with signs of autism spectrum disorder (ASD) and ADHD when the children were three years old.

NewsCould your housemates be changing your gut bacteria?
Living with friends may quietly be altering your gut bacteria - according to a new study. Research on a colony of tiny island birds reveals they share more of their gut bacteria with the birds they spend the most time with.

NewsRethinking the gut microbiome: Health is not about staying the same
Despite decades of research into the gut microbiome, microbiome-based interventions such as probiotics or fecal transplants still produce inconsistent results. Scientists suggest part of the problem may lie not in the microbiome itself, but in how we define what it means to be ‘healthy’.

NewsPueraria lobata decoction-derived vesicle-like nanoparticles reveal a novel mechanism for ulcerative colitis treatment
By simulating the traditional decoction process, researchers successfully isolated structurally intact GGD-PDVLNs from dried Pueraria lobata after boiling. These nanoparticles demonstrated remarkable stability in simulated gastric acid and intestinal fluids.

NewsResearchers to test a gut microbiome intervention as part of a cancer therapy regimen
A phase III clinical trial will test a gut microbiome intervention as part of a kidney cancer therapy regimen. The investigational agent is a once-daily capsule requiring no refrigeration or special handling.

NewsLoss of microbiota alters the profile of cells that protect the intestinal wall
Experiments in mice and human tissue indicate that a reduction in bacteria living in the large intestine decreases mucus production and affects nutrient absorption, particularly in older adults.

NewsNovel treatment protocol targets the deadliest cases of C. difficile infection
A new study demonstrated that fecal microbiota transplantation (FMT) can rapidly reverse systemic inflammation and improve survival in patients with fulminant Clostridioides difficile infection.
