NewsSimple blood test for gut bacteria metabolites could spot dementia years earlier
Scientists have discovered that subtle changes in the blood may reveal the earliest signs of cognitive decline long before symptoms become obvious.These changes are caused by chemicals produced by gut bacteria - reinforcing the idea that the gut–brain connection plays an important role in early memory changes.

NewsMissing gut bacteria may prevent some people with celiac disease from fully benefiting from high-fiber supplements or diets
Many people with celiac disease are advised to eat more fibre to support digestion and manage symptoms, either through diet or prescribed fibre supplements. New research shows that the benefits of that fibre may depend on whether the right bacteria are present in the gut to break it down.

NewsEarly pregnancy probiotics may help prevent spontaneous preterm delivery
A new study suggests that probiotics supplementation during early pregnancy may help reduce the risk of recurrent spontaneous preterm delivery (sPTD). Pregnant women who consumed probiotics containing Clostridium butyricum showed lower recurrence rates of sPTD compared with national averages.

NewsVitamin D linked to immune response to gut microbiome in inflammatory bowel disease
Vitamin D supplementation may help shape how the immune system responds to gut bacteria in people with inflammatory bowel disease (IBD), according to a new study.

NewsFiber in whole wheat foods protects against gut inflammation in mice, study finds
Enriching the diet with wheat fiber protects mice against intestinal inflammation, according to a study. The finding helps explain why incidence of inflammatory bowel disease (IBD) has increased, and suggests eating whole wheat foods may reduce one’s risk of developing it.

NewsGut microbes help convert low-protein diets into fat-burning metabolic state
Researchers identify specific bacterial strains that trigger the formation of energy-burning “beige” fat in response to dietary protein restriction.
-
NewsNew blood- and microbiome-based neural networks forecast human biological age
A new study aims to develop and compare two models for calculating biological age based on laboratory blood tests and composition of gut microbiota.
-
NewsMachine learning identifies antimicrobial peptide candidate for ulcerative colitis
Scientists applied machine learning to accelerate AMP discovery and identify candidates with therapeutic potential for ulcerative colitis.

NewsGut microbiota and the gut–brain axis: Mechanisms and therapeutic hopes for brain diseases
A new study looks at the gut–brain axis (GBA), a sophisticated bidirectional communication network that integrates neural, immune, endocrine, and metabolic pathways to govern brain function and systemic homeostasis.

NewsKimchi-derived probiotic found to promote binding and excretion of intestinal nanoplastics
Scientists have announced that a lactic acid bacterium isolated from kimchi can help promote the removal of nanoplastics from the body by binding to them in the intestine.

NewsWeaning, more than a change of food: It shapes a life-long, healthy gut
According to a team of researchers, weaning or switching from milk to solid food in early life doesn’t just change what babies eat, it helps reprogram the gut’s immune defenses to mount faster and stronger responses that can last into adulthood.

NewsNew drug candidate extremely effective against H. pylori bacterium
Researchers have discovered that metronidazole targets two central protective proteins of Helicobacter pylori: an enzyme responsible for detoxifying harmful reactive oxygen species and a protein that repairs damaged proteins.
-
NewsHeart disease risk tied to certain molecules made by gut microbes
In a study involving data from thousands of people, the risk of a new coronary heart disease diagnosis was statistically associated with bloodstream levels of nine specific molecules that are produced by gut microbes.
-
NewsHigh-fat diets cause gut bacteria to enter brain, study finds
A new study, performed using mouse models, establishes that live bacteria from an imbalanced gut microbiome can enter the brain via the vagus nerve. The vagus nerve connects the brainstem to the heart, lungs, and major abdominal organs, including the stomach, intestines, liver and more.

NewsMicrobial clues uncover how wild songbirds respond to stress
A study of free-living Northern cardinals revealed that even relatively mild challenges can leave a clear mark on the gut microbiome. Birds exposed to social or environmental stressors showed changes in the composition of their gut bacteria, while the total number of microbial types remained stable.
-
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.
