Botanical prebiotics may steer skin microbes toward healthier balance

Researchers tested plant-derived prebiotic candidates against selected skin-associated bacteria and found that garlic, flaxseed, and mango ginger extracts inhibited S. aureus or acne-associated C. acnes in vitro. Onion and guduchi extracts modestly promoted S. epidermidis, suggesting a microbiome-targeted skincare route that now needs validation in skin models and human studies.

Altering gut microbes could improve immunotherapy responses in liver cancer

Immune checkpoint blockade (ICB) has reshaped the treatment landscape for advanced hepatocellular carcinoma (HCC), offering new hope where few options existed.

Probiotic metabolite found to suppress melanoma tumor growth in mice

Immune checkpoint inhibitors like anti-PD-1 have transformed melanoma treatment, yet more than half of patients fail to respond or eventually develop resistance.

Blood metabolism maps how lifestyle tracks function in cognitive aging

A new study used pathway-level blood metabolomics to identify lifestyle-associated metabolic patterns linked to physical, cognitive, and daily functional performance across CN, MCI, and AD. The findings suggest that diet- and activity-linked pathway signals span energy, amino acid, lipid, inflammatory, oxidative stress, and microbiome-related metabolism, but require independent and longitudinal validation.

AI and multiomics reveal how gut bacteria trigger colon cancer

Over the past two decades, high‑throughput sequencing has dramatically expanded our understanding of the gut microbiome's composition.

New protocol identifies sperm biomarkers to diagnose male infertility

Researchers from the EHU-University of the Basque Country have developed a robust protocol to detect the molecules involved in the metabolic reactions of sperm.

Gut microbes emerge as potential players in estrogen-driven cancers

A new review maps how the endocrine-microbiome axis expands the estrobolome concept, showing that gut microbes may alter estrogen recycling, produce hormone-like metabolites, and shape inflammation and tissue environments in hormone-driven cancers. Human evidence remains mostly associative, so the authors call for causal models, longitudinal multi-omics, multi-kingdom profiling, and sex-stratified studies before microbiome-guided cancer strategies enter routine care.

Scientists find link between bacterium in the gut ecosystem and lupus

Scientists at UT Health San Antonio, the academic health center of The University of Texas at San Antonio, found a link between a bacterium in the gut microbiome, or ecosystem, and lupus, which could lead to more effective treatment of the disease, in a study published in Nature Communications.

Blood metabolites reveal lifestyle links to brain health before dementia

Blood metabolome profiling in dementia-free middle-aged adults linked 14 metabolites to cognition and 22 metabolites to MRI markers of brain health. Lifestyle, clinical factors, medication use and gut microbiota appeared to shape many of these metabolites, with ergothioneine emerging as a notable cognition-linked signal.

Preoperative HMB supplement improves liver regeneration quality after major surgery

Taking a supplement before a hepatectomy, a surgery in which part of the liver is removed, may help the organ recover more quickly and become more resistant to further damage.

Blueberries may boost children's memory and mood

Research suggests blueberry compounds could enhance mood and cognitive function in children, yet stronger evidence is required for clinical recommendations.

Scientists map blood chemistry links to hundreds of diseases

A UK Biobank study of nearly 390,000 people mapped 251 NMR-derived plasma metabolic traits against hundreds of health traits, prevalent diseases, and future disease outcomes. The atlas revealed tens of thousands of replicated associations, showed stronger prediction for selected short-term and cardiometabolic outcomes, and identified putative causal links that may guide future precision medicine research.

Microbes trigger cell death to boost cancer immunotherapy effectiveness

Traditional cancer treatments like chemotherapy and radiotherapy can induce immunogenic cell death (ICD), but their efficacy is often limited by drug resistance, severe off-target toxicity, and immune-related adverse events.

Psychological traits may uncover why Alzheimer’s biology differs between patients

In 822 deceased older adults from ROS and MAP, researchers linked stable psychological traits to multi-omic molecular subtypes of Alzheimer’s dementia using postmortem brain tissue from the dorsolateral prefrontal cortex. Neuroticism and loneliness were associated with molecular progression, while purpose in life showed subtype-specific inverse associations, suggesting psychological traits may align with Alzheimer’s biology beyond conventional neuropathology.

Aging immune cells may explain why autoimmunity rises later in life

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

Gut microbes may help explain why obesity and type 2 diabetes become harder to reverse

This review describes how gut microbial messengers, including SCFAs, microbiota-modified bile acids, neuroactive metabolites, and extracellular vesicles, may shape obesity and type 2 diabetes through the microbiota-gut-brain axis.

Prebiotic fiber supplement reduces harmful gut metabolites and improves liver health

A study conducted at the University of Jyväskylä, Finland, was the first to investigate the effects of prebiotic xylo-oligosaccharides (XOS) on fatty liver in humans.

Gut bacteria may help explain why fatigue appears before illness

A small study of healthy Japanese adults found that fatigue was associated with distinct gut microbiome, microbial gene, and fecal metabolite patterns. The findings suggest fatigue may track with altered microbial energy metabolism and oxidative stress-related functional potential, but larger longitudinal studies are needed to test causality and clinical value.

Glucosamine may worsen Alzheimer’s by fueling abnormal brain glycosylation

A Nature Metabolism study identifies brain hyperglycosylation as a metabolic driver of Alzheimer’s disease, with increased N-glycan biosynthesis seen in human AD tissue and mouse models. Reducing glycosylation improved memory in AD mice, while glucosamine worsened memory deficits in 5xFAD mice and was associated with poorer outcomes in dementia patients.

Short-chain oat fiber helps steady glucose and ease gut symptoms in pilot trial

A 14-day open-label pilot study in 63 healthy adults found that short-chain oat fiber was well tolerated at doses up to 20 g/day and was associated with improved gastrointestinal symptom scores.
