Periodontal bacteria trigger bone density reduction via the gut

Periodontitis, a chronic inflammatory disease of the gums, affects hundreds of millions of people worldwide and is increasingly linked to systemic disorders beyond the oral cavity.

Gut microbiota-derived metabolite directly shapes immune responses in bacterial pneumonia

Sepsis and severe pneumonia are frequently accompanied by disruption of the gut microbiota, leading to immune dysfunction and increased susceptibility to secondary infections.

New research initiative aims to predict and prevent diseases before they start

What if doctors could tell you a disease was coming years before you felt a single symptom-and stop it in its tracks? That is the goal of a sweeping new research initiative launched by the Icahn School of Medicine at Mount Sinai in collaboration with the Uniformed Services University of the Health Sciences (USU) and the Henry M. Jackson Foundation for the Advancement of Military Medicine (HJF).

Living in deprived neighborhoods reshapes the gut microbiome

This study reveals links between socioeconomic deprivation and gut microbiome changes, highlighting potential pathways to mental and metabolic health issues.

Chemical signatures in blood could help detect gallbladder cancer

Researchers at Tezpur University in Assam, India, working with scientists at the University of Illinois Urbana-Champaign, have identified distinct chemical signatures in blood that could help detect gallbladder cancer earlier.

Nutri-Score labeling system fails to reflect nutritional complexity of cocoa

Researchers at the University of Granada have revealed that the Nutri-Score labeling system, commonly used in Europe to assess food quality, is unable to adequately reflect the nutritional and metabolic complexity of soluble cocoa sold in Spain.

Metabolite-driven AI model accurately estimates time of death

Artificial intelligence can be used to provide a more precise time of death, which can be crucial in e.g. murder investigations.

Researchers show red blood cells drive better glucose tolerance at high altitude

Chronic hypoxia improves glucose tolerance in mice through insulin-independent mechanisms, with red blood cells acting as a major systemic glucose sink. Increased erythrocyte production and altered glycolytic flux help reduce circulating glucose while supporting oxygen delivery to tissues.

New review explores whether berries can slow cognitive decline linked to obesity

This systematic review in Nutrients evaluates human studies investigating whether polyphenol-rich berry consumption can modulate obesity-related metabolic dysfunction and support cognitive performance, particularly in individuals at risk of mild cognitive impairment. Evidence suggests modest memory benefits and possible metabolic improvements, although biomarker findings and long-term clinical relevance remain uncertain.

Gut microbiome may shape response to GLP-1 drugs, new review suggests

This review examines how GLP-1 receptor agonists and the gut microbiome influence one another through bile acid signaling, short-chain fatty acids, and inflammatory pathways. It explores how microbial composition may shape treatment response and highlights the need for controlled human studies to enable microbiome-informed precision therapy.

Extreme endurance exercise pushes red blood cells toward accelerated aging

Extreme endurance running damages red blood cells in ways that may affect their ability to function properly, according to a study published in the American Society of Hematology's journal Blood Red Cells & Iron.

Big breakfast study reveals protein curbs appetite but fiber delivers stronger gut microbiome benefits

A randomized crossover weight loss trial in adults with overweight or obesity found that higher protein big breakfasts improved satiety, while higher fibre breakfasts produced slightly greater weight loss and more favourable gut microbiota markers. Both diets improved metabolic biomarkers, but microbiota changes reflected surrogate gut health indicators rather than direct clinical outcomes.
