New cholesterol guidelines emphasize earlier risk assessment and prevention

New national guidance for managing cholesterol and other blood lipids emphasizes earlier risk assessment, more personalized treatment, and long-term prevention—including, in some cases, treatment beginning as early as age 30.

Scientists turn red blood cells into long-lasting drug and imaging carriers in mice

A new preclinical study shows that red blood cells can be tagged in vivo and used as long-lasting carriers for imaging agents and therapies, opening a new route for safer drug delivery and vascular imaging.

New protein atlas identifies distinct subtypes of neurodegenerative diseases

Neurodegenerative diseases form a tangled biological web with overlapping molecular signatures and symptoms. To decode this complexity, a multi-institute collaboration led by St. Jude Children's Research Hospital scientists developed the pan-neurodegeneration atlas (PanNDA).

AI-driven OCT imaging system enables precise wound healing assessment

No matter the size or severity, wounds on human skin are difficult to monitor while they heal. Biopsies disrupt the wound site and are too invasive for routine, repeated monitoring, and most medical imaging devices that could do the job are large, expensive and booked up with more pressing diagnostics.

AI-assisted decision support system improves stroke care and long-term outcomes

A clinical decision support tool that uses artificial intelligence (AI) to analyze scans after a stroke alongside treatment recommendations is associated with better quality care and long term outcomes for patients compared with usual care, finds a study from China published by The BMJ today.

Replacing sedentary time improves insulin resistance in adolescents

Adolescents who replaced just half an hour of sedentary behaviors, such as sitting on the couch or spending time at the computer, each day for moderate-to-vigorous physical activity or sleep may lower their insulin resistance, a key factor in preventing the development of Type 2 diabetes, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.

Oral semaglutide fails to slow early Alzheimer’s decline in two phase 3 trials

Two large phase 3 trials found that oral semaglutide 14 mg did not slow cognitive or functional decline over 104 weeks in people with early symptomatic, amyloid-positive Alzheimer’s disease. Semaglutide was generally consistent with its known safety profile and showed some biomarker changes, but these did not translate into clinical benefit.

Brain lesions in Down syndrome show unexpected reversible changes

What has long been interpreted as permanent and irreversible vascular damage may not be exclusively so.

Early menopause linked to higher lifetime heart disease risk

Women who enter natural menopause before age 40 face about a 40% higher lifetime risk of developing coronary heart disease than women who experience menopause later, according to a large Northwestern Medicine study that is the first to calculate lifetime heart risk associated with premature menopause.

Better cardiovascular health scores linked to lower mortality in postmenopausal women

Life's Essential 8 (LE8) and Life's Crucial 9 (LC9) from the American Heart Association are industry-accepted metrics that summarize overall cardiovascular health.

MIND diet may protect against structural brain deterioration

The combined Mediterranean and blood pressure lowering diet (MIND) may slow the structural changes related to brain aging, finds research published online in the Journal of Neurology Neurosurgery & Psychiatry.

Yogurt, cheese, and chocolate consumption is tied to reduced mortality risk, researchers report

A large meta-analysis of 50 cohort studies involving over three million adults found that higher consumption of certain fermented foods is associated with lower risks of all-cause and cardiovascular mortality. Fermented milk products also showed inverse associations with cancer mortality, while other foods like miso and bread showed no consistent effects.

Activating hypoxia signaling improves metabolism and bone health

Obesity is widely known for increasing the risk of diabetes and cardiovascular disease, but its damaging effects on the skeleton are often overlooked. Excess body fat can disrupt bone metabolism, weaken bone quality, and impair fracture repair.

Blood pressure readings may help identify future dementia risk

Measures of blood vessel health derived from routine blood pressure readings may help identify adults at increased risk for dementia, according to research being presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

New polygenic risk scores improve prediction of metabolic disease outcomes

Type 2 diabetes (T2D) and obesity are metabolic conditions with many causes, including overlapping and distinct genetic features.

New RNA therapy enhances the heart's ability to repair itself after injury

After a heart attack, cardiologists can reopen blocked vessels and restore blood flow, but the muscle cells that died will never be replaced.

Gene mutation that aids high-altitude survival could repair myelin sheath damage

A genetic mutation that helps animals like yaks and Tibetan antelopes survive at high altitudes may hold the key to repairing nerve damage in conditions such as cerebral paralysis and multiple sclerosis (MS).

Robot-assisted system found to be feasible for diagnostic cerebral angiography

Digital subtraction angiography remains the gold standard for diagnosing cerebrovascular diseases, including intracranial aneurysms, arteriovenous malformations, and arterial stenosis.

Study reveals racial differences in early Alzheimer's brain changes

A team of researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC has identified important differences in how early Alzheimer's disease-related brain changes appear across racial and ethnic groups, underscoring the need for more inclusive approaches to studying and diagnosing the disease.
