Study links better midlife vascular health to nearly 13 more dementia-free years

A long-term study of 12,409 adults found that a greater burden of diabetes, hypertension, and current smoking in midlife was associated with substantially fewer years lived free of dementia. Adults with none of these risk factors had about 30.1 dementia-free years from age 55, compared with 17.5 years among those with all three, a difference of nearly 13 years.

Why pulses could play a bigger role in healthy and sustainable diets

A narrative review finds that pulses may support gut and metabolic health through their fiber, protein, phytochemicals, and interactions with the gut microbiota, while offering a lower environmental footprint than many animal protein sources. Human evidence is strongest for selected cardiometabolic outcomes, while many microbiome and fermentation-related benefits remain supported mainly by animal and laboratory studies.

Genetic analysis of 1 million people points to FNIP1 as a promising metabolic target

Mega-scale exome sequencing of 1,032,116 people identified 59 independent genes linked to the TG:HDL ratio, including 44 rare-coding associations not detected in the previous largest analysis. Ultra-rare FNIP1 loss-of-function variants were associated with favorable fat distribution, lower liver fat and glycemia, and around 60% lower odds of a composite cardiometabolic disease outcome.

Korean study finds no overall childhood cancer link with maternal diabetes

Researchers followed 549,851 Korean children and found no statistically significant association between maternal diabetes and overall childhood cancer. The analysis linked maternal diabetes to an 81% higher relative risk of urinary tract cancer, but the absolute difference was only 37 additional cases per 100,000 offspring.

Study links lower vitamin D to mood and cognitive health in adults over 85 with diabetes

Researchers studying 188 adults aged 85 years or older with type 2 diabetes found the lowest serum 25(OH)D concentrations among those with both depressive symptoms and mild cognitive impairment. Lower levels remained associated with having both conditions after adjustment for selected factors, but the cross-sectional study cannot establish causation or a benefit from supplementation.

Heatwave exposure associated with accelerated biological aging in middle-aged and older adults

As global climate change intensifies, heatwaves are becoming more frequent, longer, and more severe, emerging as an important environmental stressor for human health.

Taiwan Biobank data reveals ongoing natural selection in living humans

For more than a century, scientists have sought to reconstruct human evolution using diverse lines of evidence, including fossils, genetic variation across populations, and ancient DNA.

Senolytic drugs rejuvenate blood stem cells in sickle cell disease

Sickle cell disease causes premature aging of blood stem cells, which scientists may be able to address with a special class of drugs, according to a new study from St. Jude Children's Research Hospital.

Early electroacupuncture intervention protects pancreatic function in prediabetes

Prediabetes refers to a metabolic state in which blood glucose is higher than normal but has not yet reached the diagnostic threshold for diabetes. It may involve impaired fasting glucose, impaired glucose tolerance, or elevated glycated hemoglobin A1c (HbA1c), and is closely associated with progressive β-cell dysfunction.

Study tests chronotype’s liver link and finds no significant association

Researchers found no significant association between chronotype and FibroScan-derived liver fat or stiffness in 119 medication-naïve adults with overweight or obesity. The exploratory findings cannot exclude smaller effects, particularly for fibrosis, and require confirmation in larger longitudinal studies.

Semaglutide vs. liraglutide: Head-to-head study reveals a diabetes risk difference

Researchers compared semaglutide with liraglutide in 57,456 insured adults without recorded diabetes or cardiovascular disease who initiated formulations indicated for chronic weight management. Semaglutide users had a lower risk of incident diabetes, particularly beyond six months of follow-up, but limited cardiovascular events prevented a precise comparison of cardiovascular risk.

Researchers use canine iPSCs to generate red blood cell-like cells

Blood transfusions are crucial in human and veterinary medicine, yet human blood reserves are in constant need of donors while blood bank systems in veterinary care are nearly non-existent.

Fish oil supplementation during pregnancy changes two childhood brain metabolic markers

Randomized maternal fish oil supplementation from pregnancy week 24 lowered offspring cerebral blood flow and oxygen metabolism at age 10 but did not alter precuneus lactate. The small differences resembled a more adult-like metabolic profile, although researchers found no associated cognitive or behavioral benefits.

Lactoferrin yogurt helps preserve iron stores in women with gestational diabetes

In a double-blind pilot trial, lactoferrin-enriched yogurt added to routine iron supplementation helped prevent ferritin decline in pregnant women with gestational diabetes and reduced iron stores. The intervention was well tolerated and produced modest changes in selected gut bacteria, but did not significantly improve anemia or metabolic outcomes.

GLP-1 receptor activation linked to lower depression and bipolar disorder odds

Genetic analyses linked BMI-related GLP-1 receptor activation to better mental well-being and lower odds of major depressive disorder and bipolar disorder. The findings do not prove that GLP-1 receptor agonist drugs treat psychiatric conditions, and randomized clinical trials are still needed.

Semaglutide dose may matter more than weight loss for heart health

The study shows semaglutide's cardiovascular benefits are more closely tied to attained dose than weight loss, challenging existing treatment assumptions.

Wearable forehead patch tracks brain-water shifts during sleep at home

A soft, wireless NIRS forehead patch tracked water-sensitive brain signals during 16 overnight home sleep recordings in four healthy men. The signals changed with EEG/EOG-defined sleep stages, suggesting a new way to study sleep-linked brain-fluid dynamics, although the device did not directly measure CSF flow or glymphatic clearance.

Semaglutide outperforms other GLP-1 drugs for weight loss in psychiatric populations

A network meta-analysis of nine randomized controlled trials found that once-weekly semaglutide showed the largest estimated weight-loss effect among GLP-1 receptor agonists tested in adults with mental illness and obesity or related metabolic risk. The authors cautioned that the findings remain preliminary because the evidence base was small, heterogeneous, and largely indirect.

Gut-friendly diet linked to lower mortality risk in coronary heart disease

Using NHANES 2005-2018 data, researchers found that adults with coronary heart disease who had higher Dietary Index for Gut Microbiota scores had lower all-cause mortality risk. The association was nonlinear, strongest when scores reached 5 or higher, and remained observational rather than causal.

Novel strategy can make stem cell transplants safer

Stem cell transplantation (also called bone marrow transplantation) and gene therapy are among the most powerful curative approaches for blood diseases such as sickle cell disease, b-thalassemia, immune deficiencies, and some blood cancers.
