NewsPrebiotic in diet linked to less impulsivity in gambling rats with traumatic brain injury
Using a prebiotic to influence bacterial activity in the gut after a traumatic brain injury may help reduce impulsive behavior, one of the common symptoms to follow a moderate blow to the head, a new study in rats suggests.

NewsThe link between the gut microbiome and autism is not backed by science, researchers say
There’s no scientific evidence that the gut microbiome causes autism, a group of scientists argue in an opinion paper. They warn that conclusions that supported this hypothesis are undermined by flawed assumptions, small sample sizes, and inappropriate statistical methods.

NewsLow-dose cannabis compound reduces side effects of HIV treatment
Long-term, low doses of THC mitigate many harmful side effects and inflammation caused by HIV and antiretroviral therapy (ART). Benefits included increased production of serotonin, while inflammation, cholesterol and harmful secondary bile acids were all reduced.

NewsGroundbreaking review reveals how gut microbiota influences sleep disorders through the brain-gut axis
A comprehensive review illuminates the intricate connections between gut microbiota and sleep regulation, establishing the microbiota-gut-brain axis as a critical pathway in understanding and potentially treating sleep disorders.

NewsResearch spotlight: Mapping how gut neurons respond to bacteria, parasites and food allergy
A new study adds to accumulating evidence showing that the enteric nervous system works closely with the immune system to help the body respond to bacteria, parasites and allergens. The ENS also plays a key role in how the body maintains balance and protects itself from harm.

NewsBabies’ gut bacteria may influence future emotional health
A child’s early gut microbiome may influence their risk of developing depression, anxiety or other internalizing symptoms in middle childhood, according to a new study.

NewsNew role of gut bacteria provides hope for a novel IBS treatment
Research clarifies the complex interaction between gut bacteria and IBS, identifying two bacteria that together can produce serotonin: Limosilactobacillus mucosae and Ligilactobacillus ruminis.

NewsExercise counteracts junk food’s depression-like effects through gut-brain metabolic signaling
New research into metabolic pathways demonstrates that voluntary running exercise can mitigate depression-like behaviors induced by high-fat, high-sugar diets associated with both circulating hormones and gut-derived metabolites.

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.

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.

NewsHow microbial strain variations influence neurobehavior
Microbial single nucleotide variations influence host cognitive behavior by regulating metabolism, a new study of merino sheep reveals.

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.

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.
-
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.

NewsOral bacteria linked to Parkinson’s via the gut-brain axis
Researchers have identified the mechanism by which metabolites produced by oral bacteria in the gut may trigger the development of Parkinson’s disease.

OpinionUnderstanding the gut microbiome: are we missing essential information?
Undoubtedly, the gut microbiome is key to understanding the impact of diets and lifestyles on health. However, despite decades of scientific advancements, the connection between gut microbiome shifts and perceived health benefits remains unclear.
-
NewsNew papers reveal how gut-brain interactions shape eating behaviors
Researchers found that stress from life circumstances can disrupt the brain-gut-microbiome balance. This disruption may alter mood, decision-making, and hunger signals — increasing the likelihood of craving and consuming high-calorie foods.
-
NewsNewly discovered ‘sixth sense’ links gut microbes to the brain in real time
Researchers have uncovered what they call a “neurobiotic sense,” a newly identified system that lets the brain respond in real time to signals from microbes in our gut. Tiny sensor cells lining the colon’s epithelium detect a microbial protein and send rapid messages to the brain.

NewsYour microbiome, your medicine: Scientists gather in Valencia to redefine the future of health
The International Society of Microbiota (ISM) will host the 12th World Congress on Targeting Microbiota, presenting groundbreaking research that positions the human microbiome as a central determinant of health and disease across multiple organ systems.

NewsAcupuncture eases opioid therapy, rebalancing gut microbiota, study shows
Acupuncture significantly lowers methadone doses for people undergoing treatment for opioid use disorder, while restoring antiviral immune responses and rebalancing gut microbiota and metabolism, according to a new study.
