Thymus health in adults linked to longer life and disease risk

Two new studies from investigators at Mass General Brigham challenge a decades-old assumption that the thymus, an organ best known for its role in establishing immune function in childhood, becomes irrelevant in adulthood.

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.

Study finds a clear link between ultraprocessed food and heart disease risk

A prospective analysis of 6,531 adults in the multiethnic MESA cohort found that higher ultraprocessed food intake was associated with a graded increase in incident ASCVD risk, with each additional daily serving linked to about a 5% higher risk. The association was stronger in Black participants, while no significant interaction was seen by sex or income.

Gut-derived blood markers may help predict who develops coronary heart disease

Researchers used five prospective cohorts from the US and China to identify circulating gut microbiota-related metabolites linked to future coronary heart disease, then tested the findings through discovery, in silico validation, and targeted quantitative validation. The study ultimately highlighted nine metabolites associated with incident CHD, supporting a potential role for microbial metabolism in heart disease risk while not proving causation

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.

Burnout crisis demands science-based strategies beyond self-care solutions

Burnout is at an all-time high, with some studies saying two-thirds of employees now cite job burnout as a major challenge.

Study finds common brain mechanism behind different anesthesia drugs

When patients undergo general anesthesia, doctors can choose among several drugs. Although each of these drugs acts on neurons in different ways, they all lead to the same result: a disruption of the brain's balance between stability and excitability, according to a new MIT study.

Math-based model helps optimize treatment for chronic eczema

Anyone with a chronic illness understands the struggle of living with a disease that is deeply unpredictable.

Gut microbe molecules linked to coronary heart disease risk

In a study involving data from thousands of people, the risk of a new coronary heart disease diagnosis was statistically associated with bloodstream levels of nine specific molecules that are produced by gut microbes.

Belly fat linked to heart failure risk through inflammation

New research suggests that measures of excess weight around the waist (central obesity or visceral fat) may increase the risk of heart failure primarily due to inflammation, according to findings presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.

Study identifies risk factors for readmissions after shoulder replacement surgeries

Shoulder replacement is the third most common joint-replacement surgery in the U.S. and is likely to become more common as the population ages, according to Penn State researchers.

Tailored prediabetes treatment may better prevent Type 2 diabetes

A one-size-fits-all approach to prediabetes treatment may miss the opportunity to implement an early, more intensive, tailored prevention approach for those with the highest risk of developing Type 2 diabetes, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.

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.

How one antibiotic dose can reshape your gut microbiome for years

Long-term registry-linked analysis of nearly 15,000 adults shows that antibiotic use is associated with persistent changes in gut microbiome diversity and composition for up to 4–8 years. These effects vary by antibiotic class, with clindamycin, fluoroquinolones, and flucloxacillin showing the strongest and most sustained associations.

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.

Researchers show how smartwatches can help identify insulin resistance

Researchers developed a scalable framework that predicts insulin resistance using wearable-device signals, routine blood biomarkers, and demographic data, with stronger performance when these data streams were combined. The study also introduced an AI agent to explain insulin resistance risk, interpret results, and support earlier metabolic risk screening.

Researchers use multiview deep learning to enhance echocardiogram analysis

Heart disease is the leading cause of adult death worldwide, making cardiovascular disease diagnosis and management a global health priority. An echocardiogram, or cardiac ultrasound, is one of the most commonly used imaging tools employed by physicians to diagnose a variety of heart diseases and conditions.

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).

Ultra-processed food consumption associated with increased risk for heart disease

People who consumed over nine servings of ultra-processed foods per day on average were 67% more likely to suffer a major cardiac event than people consuming about one serving of such foods per day, in a study being presented at the American College of Cardiology's Annual Scientific Session (ACC.26).
