Mediterranean diet delivers gut health benefits for expectant mothers

A Mediterranean diet during pregnancy significantly alters the maternal gut microbiome, increasing beneficial bacteria, while a mindfulness-based stress reduction program shows more limited effects. Neither intervention affected the vaginal microbiome, and the clinical significance of these changes requires further study.

Cedars-Sinai study finds new way to combat Alzheimer’s in preclinical models

In a preclinical study, Cedars-Sinai investigators found that boosting angiotensin converting enzyme (ACE) in key immune cells called microglia in the brain helped protect the brains of specially bred laboratory mice against Alzheimer's disease.

Faster and further walking lowers heart disease and stroke risks

Analysis of over 36,000 people with high blood pressure has shown that taking more steps, even below the recommended daily target of 10,000 steps, and walking faster, is associated with a significant reduction in the risk of major problems of the heart and blood vessels.

Scientists map the genes behind diet and dementia risk

Researchers established a high-quality genetic dataset from the MIND diet trial, enabling new studies of gene–diet interactions in cognitive health. This resource allows deeper investigation into why individuals respond differently to dietary interventions targeting dementia risk.

Flavonols found in foods can block drug resistance protein and boost medication absorption

Researchers identified specific flavonols that potently inhibit breast cancer resistance protein (BCRP), a key driver of drug resistance and poor oral drug absorption. The study found that these flavonols can reverse chemotherapy resistance in vitro and boost drug exposure in animal models, though clinical translation remains uncertain.

Heart cells adapt and stretch to shape a healthy beating heart

Researchers at the Francis Crick Institute have discovered that the heart's own contractions trigger biological signals that guide the formation of a functional beating heart.

Air purifiers can lower blood pressure in at-risk adults

Using portable high-efficiency particulate air (HEPA) purifiers at home can significantly lower systolic blood pressure (SBP) in adults with elevated baseline readings — even in areas with relatively low overall air pollution levels, according to a study published today in JACC, the flagship journal of the American College of Cardiology.

TEER shows promising outcomes in elderly patients with atrial functional mitral regurgitation

The mitral valve controls blood flow between the heart's left atrium and ventricle. When structural changes affect the atrium or valve, it may not close fully-causing blood to leak backwards, a condition known as atrial functional mitral regurgitation (AFMR).
