It is a mystery that has puzzled scientists for years. How can the world's only winged mammals carry viruses that cause severe disease while rarely becoming seriously ill themselves?

Preferences about healthcare-including risk aversion, openness to experimental treatments, and whether to leave treatment decisions to a doctor-vary substantially by age and sex in adults over 50.

For decades, scientists believed that photoreceptors in the retina relied primarily on neighboring support cells, known as the retinal pigment epithelium (RPE), to remove waste. While the RPE is still responsible for clearing away the worn-out tips of photoreceptors each day, new findings from the University of Oklahoma reveal that photoreceptors also perform much of their own internal housekeeping.

A lack of data on prisoner characteristics is providing an incomplete picture of who dies in prison and why, which may be contributing to preventable deaths in custody, according to a new report.

Scientists created an AI system that uses facial recognition and real-time, touchscreen testing to automate cognitive studies of capuchin monkeys in the wild.

A University of Houston psychologist has received a $2.8 million grant from the National Institute of Child Health and Human Development to lead the first randomized clinical trial testing whether a remotely delivered parenting program can improve healthy infant brain development to support long-term mental health outcomes for babies born prematurely.

The National Institute of Allergy and Infectious Diseases of the National Institutes of Health has awarded a new, five-year $2.4 million R01 grant to Dr. Jiahui Ding, assistant professor of obstetrics and gynecology at the Wayne State University School of Medicine's C.S. Mott Center for Human Growth and Development, to support research that aims to uncover how viral infections during pregnancy reprogram the developing immune system of the fetus, influencing susceptibility to infectious diseases throughout life.

New research published in Neuro-Oncology gives a glimpse at promising discoveries that could help shape the future of glioblastoma treatment and patient outcomes.

Los Angeles County residents living in evacuation warning or order zones during the 2025 wildfires experienced heightened levels of anxiety and depression almost a year later, according to new USC research.

The composition of donor cord blood may play a critical role in the success of chimeric antigen receptor (CAR) natural killer (NK) cell therapies.

Malaria is the deadliest climate-sensitive infectious disease. Yet, researchers and public health officials have long argued over how climate change has shaped its spread.

Traditionally, public health programs have relied on chemicals for mosquito management, and this may be why combating them is becoming more difficult.

A world-first scabies control program has drastically reduced cases of the highly contagious parasitic skin disease in Solomon Islands and Fiji, according to a new study.

An overactive immune response in the brain may play a role in Dravet Syndrome, a rare and severe genetic epilepsy that typically begins in infancy, according to Weill Cornell Medicine researchers.

Mouse liver cells are not a suitable host for hepatitis E viruses. The Virology department in Bochum has discovered why.

Cardiomyopathies are a group of mostly hereditary, rare heart diseases in which the structure of the heart muscle tissue is impaired.

Women who reach menopause before age 40 face a meaningfully higher risk of developing high blood pressure than those who go through menopause after age 45, according to a new study of more than 107,000 women.

A gene editing tool designed to precisely rewrite the gene that causes Huntington's disease reduced toxic protein fragments and symptoms associated with the disease in mice, researchers at the University of Illinois Urbana-Champaign report.

Nearly 23 million Americans with blood pressure 130/80 mm Hg or higher may be eligible for blood-pressure-lowering medications based on the 2025 American Heart Association/American College of Cardiology guideline, according to new, independent research published today in the Journal of the American Heart Association, an open access, peer-reviewed scientific journal of the American Heart Association.
