Researchers discovered that clogged brain "drains" show up early in people at risk of Alzheimer's disease. These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup linked to memory loss and cognitive decline. In some ...

Menopause symptoms are common among female endurance athletes and often interfere with training and performance. A survey of women aged 40-60 who train regularly found high rates of sleep problems, exhaustion, anxiety, weight gain, and joint pain. .. ...

Common diabetes drugs may do more than regulate blood sugar--they could also influence how cancers grow, spread, or slow down. Researchers are now unraveling how these medications affect immune function, inflammation, and tumor biology, with ...

A new gel developed by McGill researchers could change how vocal cord injuries are treated. The injectable material lasts far longer than current options, staying intact for weeks instead of breaking down quickly. By acting like a molecular glue, it ...

Dry eye disease affects millions of people, causing burning, redness, and constant eye fatigue that can worsen over time. Scientists now believe the problem may begin deep inside tear glands, where a vital cellular cleanup process fails to function . ...

Attention depends on the brain's ability to filter out distractions, but new research suggests this works best when background brain activity is quieter. Scientists found that lowering certain versions of the Homer1 gene improved focus in mice by ...

A new study suggests the vagus nerve may be one of the heart's most important defenders against aging. Researchers found that keeping this nerve connected to the heart helps protect heart cells and maintain strong pumping ability. Even partial ...

Being active boosts your daily calorie burn more than previously thought. Researchers found that increased physical activity raises total energy use without triggering the body to conserve energy elsewhere. Basic functions keep running at full speed, ...

Scientists studying Alzheimer's in African Americans have uncovered a striking genetic clue that may cut across racial lines. In brain tissue from more than 200 donors, the gene ADAMTS2 was significantly more active in people with Alzheimer's than in ...

A first-of-its-kind national trial shows that public Montessori preschool students enter kindergarten with stronger reading, memory, and executive function skills than their peers. These gains don't fade -- they grow over time, bucking a long ...
