Mental health inequities observed across American Indian and Alaska Native subgroups in California

The fatality rate for H5N1 highly pathogenic avian influenza in humans has historically been high, with more than half of people dying. Why, then, is the current H5N1 bird flu outbreak—which has caused massive die-offs in wild birds, farmed poultry and even wild mammals—causing mostly mild symptoms in the people it has infected?

Why do so many people relapse after quitting cocaine? A new study from The Hebrew University reveals that a specific "anti-reward" brain circuit becomes hyperactive during withdrawal—driving discomfort and pushing users back toward the drug. Surprisingly, this circuit may also serve as a built-in protective mechanism, offering new hope for addiction treatment.

Optical coherence tomography (OCT), a tool routinely used to diagnose and plan treatment for eye diseases, has now been modified to collect images of the inner ear.

A new Penn Nursing initiative explores the impact of federally funded international bioethics training programs. The collaborative initiative, published in the Journal of Empirical Research on Human Research Ethics, highlights both the significant achievements and ongoing challenges in building bioethics research capacity in low- and middle-income countries (LMICs).

Women from ethnic minority backgrounds or areas of high social deprivation are at higher risk of postpartum hemorrhage (PPH), according to a new study led by Keele University.

The US health department said Wednesday it would end the use of a vaccine ingredient long targeted by conspiracy theorists over debunked claims it causes autism.

Flossing your teeth at least once a day is an essential part of any oral health routine. But it might also one day protect other parts of the body as scientists have created a novel, needle-free vaccine approach using a specialized type of floss.

A newly published study in the European Journal of Oncology Nursing, led by Dr. Thinh Toan Vu at the Center for Innovation in Mental Health with Associate Professors Sasha Fleary, Glen Johnson, and Victoria Ngo, reveals that over half of family caregivers for lung cancer patients in Vietnam report low resilience. This raises urgent concerns about caregiver mental health and the sustainability of informal care within an already overstretched health system.

For her doctoral dissertation, Senior Planning Officer Idil Hussein studied the intentions of Finnish parents in terms of allowing their children to have human papillomavirus (HPV) and influenza vaccines.

Heavy metal rocker Ozzy Osbourne died this week at 76, just weeks after his farewell show and about five years after announcing he had Parkinson's disease.

A new study shows that the human gut microbiota can pinpoint whether an adult lives in Wuhan or Shiyan, two cities 500 km apart in China's Hubei Province, with 94% accuracy. This microbial signature is strongly linked to each city's characteristic diet.

Low doses of the injectable weight-loss medication semaglutide may improve symptoms of a hard-to-treat type of heart failure. This effect happened through direct action on the heart muscle and blood vessels, despite resulting in no significant weight loss, according to preliminary research presented at the American Heart Association's Basic Cardiovascular Sciences Scientific Sessions (BCVS 2025). The meeting, held in Baltimore, July 23–26, 2025, offers the latest research on innovations and discovery in cardiovascular science.

It is impossible to imagine life without the smartwatch for a huge group of people. About 455 million consumers worldwide used a smartwatch in 2024. They are especially popular among young adults (18–34 years old); in this age group, about 40% use a smartwatch.

A team of Memorial Sloan Kettering Cancer Center (MSK) researchers have made an important finding about why genetically engineered immune cells sometimes fail to finish the job when given as a cancer treatment. The new discovery sheds light on the tendency of these modified cells to lose power or even self-destruct before fully destroying a tumor. This is a major problem, for example, in chimeric antigen receptor (CAR) T cell therapy.

Drawing on a landmark 25-year study that followed Quebec children into adulthood, McGill University researchers have identified two distinct patterns in how suicidal thoughts emerge and the early signs that are often missed.

Restrictive practices in mental health settings—such as physical restraint and seclusion—are meant to be a last resort, used only when patients pose a risk to themselves or others.

On hot summer days, few things are more refreshing than a dip in the pool. But have you ever wondered if the pool is as clean as that crystal blue water appears?
