Dual-drug microneedle patch targets inflammation and fat browning

The worldwide obesity crisis has become a dominant public health crisis across the globe. Over 3 billion people worldwide currently suffer from obesity, and forecasts warn the number will rise above 4 billion by 2035, accounting for more than half the global population.

Physics-informed AI framework improves aortic aneurysm stress prediction

Ascending thoracic aortic aneurysms often progress silently, but once dissection or rupture occurs, they can cause severe mortality before hospital arrival or during admission.

Tumor environments sculpt diverse natural killer cells for cancer therapies

For decades, natural killer (NK) cells have been classified into two main groups based on surface markers: one specialized for cytokine production and the other for direct killing.

What your gut microbes may have to do with how your brain ages

This review examines how diet-driven changes in the gut microbiota and microbial metabolites may influence cognitive aging through immune, metabolic, neural, endocrine, and barrier-related pathways. It highlights SCFAs, tryptophan-derived metabolites, and bile acids as key signaling mediators while emphasizing that much of the mechanistic evidence remains preclinical and human evidence is largely associative.

As life expectancy rises, healthy aging is more important than ever

Global disease burden is shifting toward aging-related conditions as people live longer, with these diseases now representing the largest expected lifetime health burden for newborns across all income groups. Modeling suggests that reducing aging-related disease could produce unusually large and progressively greater gains in both longevity and healthy life expectancy because improvements in survival and health reinforce one another.

Semaglutide extended lifespan in older female mice, but that was not the only finding

Late-life semaglutide treatment slowed age-related physiological decline, attenuated multiple molecular hallmarks of aging, and extended median lifespan from 742 to 834 days in aged female mice. The drug reproduced many effects of calorie restriction while providing additional benefits in exploratory behavior, spatial memory, and glucose control, suggesting that some effects extend beyond reduced calorie intake alone.

Coffee, tea and dementia risk: Why the amount you drink could matter

A targeted perspective synthesizes epidemiological and mechanistic evidence examining how caffeine consumption during midlife may influence dementia risk later in life. The authors highlight potential roles for dose, age, CYP1A2 genotype, adenosine signaling and cultural drinking practices, while stressing that current observational evidence cannot establish causality.

The four-day week has plenty of fans. Now researchers are testing what it really changes

The Sussex 4-Day Week study is a 14-week UK protocol designed to investigate how reduced working hours affect physical and mental health, wellbeing, sleep, work performance, and potential biological and psychological mechanisms. Researchers aim to combine questionnaires with actigraphy, inflammatory biomarkers, interoception testing, and brain imaging in at least 150 adults, with data collection expected to continue until 2027.

Study finds biases in tools predicting dangerous genetic mutations

When a patient has their DNA read, it gets compared against a reference version of the human genome. It allows geneticists and rare disease experts to look at a list of places where the patient's DNA differs.

Yeast study shows how membrane lipids slow protein transport

A study in budding yeast suggests that changes in membrane lipids trigger a braking system that slows internal protein transport when the endoplasmic reticulum comes under stress, comparable to modern logistics networks where shipments are slowed when distribution hubs are under stress.

Shared biological pathways may explain chronic fatigue across diseases

A shared biological secret that helps explain chronic exhaustion in conditions including long Covid and PTSD has been discovered by researchers at the University of East Anglia and Oxford BioDynamics.

Why addiction researchers are paying closer attention to GLP-1 drugs

A Journal of Clinical Investigation Viewpoint highlights growing evidence that GLP-1 receptor agonists, particularly semaglutide, may reduce alcohol consumption and some other substance-related outcomes by acting on brain systems involved in reward, motivation, stress, and emotion. However, the authors caution that efficacy for substance use disorders is not yet firmly established and call for further research into optimal dosing, treatment duration, patient selection, mechanisms, and effects across different addictions.

Your weekend meal schedule may matter more than you think

In a prospective analysis of 104,806 adults from the NutriNet-Santé cohort, greater differences in meal timing between weekdays and weekends were associated with higher risks of cardiovascular disease and coronary heart disease in men over a median 8.1 years. The associations were strongest when weekend eating shifted earlier, while delayed weekend eating was linked specifically to coronary heart disease, with no association detected for cerebrovascular disease.

Post-trauma mental health conditions increase future cardiovascular risks

Mental health conditions, such as posttraumatic stress disorder (PTSD), substance abuse, depression and anxiety, can develop after people experience trauma.

Study reveals why many patients fail to recover after stroke

A clot forms. Blood flow to the brain is blocked. Starved of oxygen, neurons begin to die.

Study shows ending free school meals increased elementary student hunger

A recent study in the Journal of Nutrition Education and Behavior (JNEB), published by Elsevier, explored elementary school teachers' experiences before and after the end of the federal universal free school meals (UFSM) policy.

Bridging science and family story to understand schizophrenia origins

Twin studies have placed the heritability of schizophrenia at roughly eighty percent for decades. Concordance between identical twins, who share the entire genome, does not reach fifty percent. Both figures are well established, and they do not fit together comfortably.

Bacterial protein fragment corisin found to drive pulmonary fibrosis

A bacterial protein fragment called corisin drives the process of pulmonary fibrosis by infiltrating and disrupting the cell's quality-control system, researchers at the University of Illinois Urbana-Champaign and Mie University in Japan found in a new study.

Stay sharp after menopause: How aerobic exercise can improve key thinking skills

Regular aerobic exercise – the kind that gets your heart pumping – can improve important thinking skills called executive functions, and the benefits appear especially strong for women after menopause, according to Rutgers researchers.

Researchers found one childhood behavior linked to folic acid use before pregnancy

Researchers analyzed 646 children aged 2–8 years and their 563 mothers to examine whether maternal folic acid supplementation before conception was associated with childhood behavioral difficulties. Preconception supplementation was associated with a 34% lower risk of peer relationship problems, while no significant associations were found for total behavioral difficulties, emotional, conduct, hyperactivity/inattention, or prosocial problems.
