Study finds high levels of social infrastructure lead to healthier communities

Avian influenza virus from the ongoing outbreak in dairy cattle appears to be keeping its bird-infecting features rather than adapting to better infect other mammals, according to a new study from St. Jude Children's Research Hospital. Since 2024, when scientists first detected H5N1 bird flu in dairy cattle, they have worried that the virus would use the animals as a bridge to mutate and gain the ability to better infect and spread in humans.

Among adolescents with overweight or obesity, prediabetes is more than twice as common in Asian and Pacific Islander (Asian/PI) adolescents than in White youth, according to a study published online June 30 in Diabetes Care.

A new discovery made by researchers from The Australian National University (ANU) could lead to smarter, more effective treatments for Hodgkin lymphoma, a common blood cancer.

Planned Parenthood clinics across the country will continue to receive Medicaid funding, at least for now.

Exposure to nature—even in a virtual setting—can enhance the emotional well-being and quality of life for older adults living with dementia.

A study led by doctors at the Medical University of South Carolina and UMass Chan Medical School found that ultrasound-guided nerve blocks helped kids with broken thigh bones, also known as femurs, feel less pain and need fewer systemic medications than children who didn't get the injections.

Several studies have indicated that forgotten memories may not be as irretrievable as once thought. Memory appears to be closely tied to the context in which it was encoded. Consequently, remembering smells, sounds and other environmental cues, as well as any feelings experienced during the time the memory was formed can help to recall the memory. However, these memory studies have not sufficiently determined how this kind of contextual memory recall is forgotten after recall.

Increases in local homicide rates in U.S. counties are linked to higher suicide rates the following year, particularly when firearms are involved, according to Rutgers researchers.

The American College of Chest Physicians (CHEST) recently released a new clinical guideline on the management of patients with early-stage non-small cell lung cancer (NSCLC). Published in the journal CHEST, the guideline contains 17 evidence-based recommendations to provide a framework for surgeons to implement in their own practice.

People in the UK eat a median of eight different plants a day—including spices and fat-based oils—with some eating just two daily.

Sixty years ago this week, President Lyndon Johnson signed Medicare into law, giving all Americans over 65 access to health coverage.

The first malaria treatment for babies and very young children of 2 months up to 5 years was approved for use by Swiss agency for therapeutic products, Swissmedic, in early July 2025. Until now, babies and very young children have been treated with medicines formulated for older children.

Circulating tumor cells (CTCs) refer to cancer cells that have broken off from a primary tumor. These tumor cells can travel through the blood in the circulatory system and lodge themselves in other organs to cause secondary tumors. Therefore, the detection and subsequent characterization of CTCs from blood can help in the clinical diagnosis and treatment of various cancers. However, the efficient capture of CTCs from blood has been proven to be difficult.

Diarrhea remains one of the most serious health threats to young children in the Global South, and new research shows that climate change is set to worsen the risk substantially. However, improved access to education and targeted health policies could help families protect their children from this deadly disease.

A new study published in the American Journal of Health Promotion finds that inadequate leisure-time aerobic physical activity accounts for $192 billion in annual health care costs among U.S. adults—12.6% of total national health care spending.

Weill Cornell Medicine researchers have discovered that PD-1—a molecule best known for putting the brakes on immune cells—also plays a critical role in helping T cells become long-term immune defenders in the skin. Early during infection, PD-1 acts like a steering wheel, guiding T cells to become protective resident memory T cells (TRM) that stay in place. These cells remember invading germs or cancer and quickly mount a response if that enemy reappears.

A Stanford University-led investigation into the COVID-19 vaccination effort reports that it averted an estimated 2.533 million deaths and 14.8 million life-years worldwide between 2020 and 2024.

Patients with bronchial asthma suffer from attacks of shortness of breath caused by constricted airways. "Anti-inflammatory medications are usually given to treat this, although it isn't quite clear how inflammation and constriction correlate," says Professor Daniela Wenzel, head of the Department of Systems Physiology in the Faculty of Medicine at Ruhr University Bochum.
