Airborne antimicrobial resistance poses overlooked global public health threat

The air we breathe serves as a silent vector of antimicrobial resistance, calling for the need to integrate air monitoring into global public health strategies, according to a review by an international team of researchers.

Gut microbiome changes improve memory in early cognitive decline

Research shows that modifying the gut microbiome can enhance cognitive performance and mitigate dementia risk, highlighting the gut-brain connection.

Fiber supplement stabilizes blood sugar in gestational diabetes

Dietary fiber supplementation shows potential in managing blood sugar levels and preventing preterm births in pregnancies at risk for gestational diabetes.

Blood test may detect cognitive decline years before symptoms

A blood test could help identify people at higher risk of cognitive decline years before a traditional diagnosis is possible – according to University of East Anglia research.

Gut bacteria determine fiber benefits in celiac disease patients

Many people with celiac disease are advised to eat more fiber to support digestion and manage symptoms, either through diet or prescribed fiber supplements.

Antibiotic resistance genes found in both diseased and healthy lungs

The researchers examined patients with COPD, asthma, pulmonary fibrosis (IPF), and sarcoidosis, and compared them with healthy individuals.

Why vaginal microbiota transplants aren’t working yet

Vaginal microbiota transplantation without antibiotics fails to restore microbiome balance, yet engraftment suggests avenues for enhancing treatment efficacy.

How gut imbalance may drive obesity, diabetes, and heart disease

A new review argues that gut dysbiosis is closely linked to metabolic dysfunction through intertwined effects on inflammation, oxidative stress, gut barrier integrity, microbial metabolites, and epigenetic regulation. It also highlights microbiome-targeted strategies such as high-fiber diets, probiotics, prebiotics, postbiotics, exercise, and fecal microbiota transplantation as promising ways to support metabolic health.

How do diet, smoking, alcohol, and stress reshape the female microbiome?

This review examines how modifiable lifestyle and environmental factors shape the female vaginal, gut, oral, and skin microbiomes, with diet, alcohol, smoking, obesity, stress, hygiene, physical activity, and sexual behaviours all linked to site-specific microbial shifts. It argues that understanding these patterns could help guide future female-focused prevention and intervention strategies.

Natural peptide in sweat may help block flu infection before symptoms start

Researchers led by the Fisabio Foundation found that dermcidin, a natural antimicrobial peptide present in sweat and respiratory tissues, can block influenza infection by binding to a highly conserved region of the viral hemagglutinin protein and preventing cell entry. The study also found that people who did not develop flu-like symptoms had markedly higher baseline dermcidin levels, suggesting the molecule may help reduce susceptibility to infection and could support the development of broader-spectrum antivirals.

Probiotic therapy may offer a simple strategy to help prevent premature births

Preterm birth is a major cause of neonatal illness and death, especially among women with a history of premature delivery.

Parasites trigger a gut-to-brain signal that cuts food intake during infection

Researchers found that intestinal tuft cells signal to crypt enterochromaffin cells by releasing acetylcholine, triggering serotonin release and activating a gut-to-brain vagal pathway during type 2 inflammation. This sustained signalling, rather than the initial acute response, was linked to reduced food intake in mouse models of parasitic infection.

Gut immune responses found to trigger brain inflammation in MS

Multiple sclerosis (MS) is a debilitating neurological disorder caused by malfunctioning immune responses that target the brain and spinal cord of the central nervous system (CNS).

Study reveals how a promising bacterial therapy reduces recurrent bacterial vaginosis

A new study from the Kwon Lab at the Ragon Institute, published in Cell Host & Microbe, provides the most detailed picture yet of how a promising bacterial therapy works to prevent recurrent bacterial vaginosis (BV) and why it works better for some women than others.

New AI tool assesses the potential threat posed by new bacteria

Researchers have developed an AI tool that can help determine whether unfamiliar bacteria carry genetic features linked to disease.

Molecular test shows high sensitivity in detecting bile duct cancer

When patients develop a narrowing or blockage in the bile ducts – the tubes connecting the liver, gallbladder and intestines – physicians must determine whether the cause is cancer or a benign condition.

Do multi-strain probiotics improve long covid symptoms?

Multi-strain probiotics show potential to modulate gut microbiome in long COVID, yet their impact on inflammation and recovery is not statistically significant.

Study explores racial differences in gastric cancer immunotherapy outcomes

Advanced gastric cancer remains one of the deadliest malignancies, with a 5-year overall survival rate below 10%.

Heavily processed foods may raise heart disease risk beyond poor nutrition alone

A 2026 review in Cardiology in Review reports that higher intake of ultra-processed foods is consistently associated with greater risks of cardiovascular disease, stroke, and cardiovascular mortality across cohort studies and meta-analyses. The paper also highlights plausible mechanisms involving gut dysbiosis, oxidative stress, and NF-κB-driven inflammation, with additives such as emulsifiers, preservatives, dyes, and sweeteners discussed as potential contributors.

Vitamin D may help shape how the immune system responds to gut bacteria in IBD patients

Vitamin D supplementation may help shape how the immune system responds to gut bacteria in people with inflammatory bowel disease (IBD), according to a Mayo Clinic–led study published in Cell Reports Medicine.
