Using vaginal estrogen tablets was not associated with an increased risk of recurrent ischemic stroke among postmenopausal women in a registry in Denmark, according to research published today in Stroke, the peer-reviewed scientific journal of the American Stroke Association, a division of the American Heart Association.

The Global Virus Network (GVN), in partnership with the University of South Florida (USF) Youth Experiences and Hillsborough County Public Schools STEM Department, recently concluded its inaugural "Global Guardians: Youth for Pandemic Preparedness" summer camp, an immersive, hands-on experience that brought together some of Tampa's brightest high school students with internationally renowned virologists, public health experts, and scientists.

How does one identify something no one has a test for? Designer drugs replicate the effects of known, illicit drugs but evade law enforcement. The chemical structure variations that help these compounds avoid detection also make them unpredictable in the body - a quality that poses serious health consequences.

Generous parental insurance can improve the mental health of new parents. However, the way the insurance is designed risks excluding those who need the support most. This is shown in a new doctoral thesis from Karolinska Institutet and Stockholm University.

Most people recover from Dengue fever, which is caused by a virus transmitted from the Asian tiger mosquito, but some infected individuals experience serious bleeding, a sudden drop in blood pressure, and even death.

The European Regulation list on mandatory labelling of foods includes 14 allergenic foods. Research published in Clinical & Experimental Allergy has identified eight additional foods frequently involved in food-induced anaphylaxis.

Research shows that early childhood maltreatment is associated with significant delays in social and cognitive development. Unfortunately, according to the United States Department of Health and Human Services, children under age one face the highest risk of maltreatment, particularly neglect. The Child Protective Services (CPS) system is responsible for responding to maltreatment and preventing its recurrence.

From "try yoga" to "start journaling," most mental health advice piles on extra tasks. Rarely does it tell you to stop doing something harmful.

It's been a long-accepted reality that with age comes increased inflammation – so widely accepted it's been dubbed "inflammaging."

A new study finds that a high-salt diet triggers brain inflammation that drives up blood pressure.

Landscape changes across the East Asian–Australasian Flyway have reshaped waterfowl migration, increasing interactions with poultry. This shift amplified cross-species viral transmission and raised the risk of avian influenza virus reassortment and diversification.

A new national study led by researchers from Carleton University and the University of Toronto reveals that older adults living in greener neighborhoods were less likely to experience depression during the early months of the COVID-19 pandemic.

A Canadian review synthesizes genetic factors that influence vitamin D synthesis, metabolism, and transport, highlighting how polymorphisms affect circulating levels. It also explores how gene-environment interactions shape individual responses to supplementation and sunlight.

Having a larger waistline, high blood pressure and other risk factors that make up metabolic syndrome is associated with an increased risk of Parkinson's disease, according to a study published on August 20, 2025, in Neurology, the medical journal of the American Academy of Neurology.

Two new scoring systems reveal that Americans who eat more nutrient-dense grains, whether whole or fortified, have better diets, lower obesity rates, and improved metabolic health. The cross-sectional analysis of NHANES data shows that these “healthy grains” are also affordable and widely available.

Researchers found that post-learning music changes emotional arousal, which in turn shapes memory differently across individuals. Moderate arousal boosted detailed memory, while extremes favored gist, showing music’s unique but variable impact on consolidation.

A new review reveals how everyday foods and hidden exposures to formaldehyde may fuel insulin resistance and chip away at memory, but also points to dietary patterns and emerging therapies that could help reduce the risk.

In a new study led by the University of Pennsylvania School of Veterinary Medicine (Penn Vet) and Children's Hospital of Philadelphia (CHOP), researchers found that mitochondrial dysfunction in the blood-brain barrier (BBB) may lead to neuropsychiatric disease in some patients with 22qDS.

Effectively managing chronic conditions like diabetes and hypertension can greatly improve quality of life, reduce complications and extend longevity for older adults.

Cleveland Clinic researchers have discovered a connection between elevated blood levels of TMAO (trimethylamine N-oxide) - a byproduct of gut bacteria digestion of nutrients found in red meat and other animal products - and a higher risk of abdominal aortic aneurysms.
