PrEP insurance denials and cost-sharing persist for many, despite accessibility efforts

Over the last six months, there have been several policy changes affecting children's nutrition benefits, vaccine mandates, and more. A new survey from Emory University's Rollins School of Public Health reveals how American adults view these recent federal actions and proposals.

The bird flu virus that has been spreading among dairy cows may travel through the air and wastewater at farms, not just from milking equipment, a new study finds.

For decades, MRI (magnetic resonance imaging) has been a powerful way to see inside the human brain. A specialized form, diffusion-weighted MRI (dMRI), can measure tissue properties of fiber pathways in the brain by measuring the movement of water molecules. Since dMRI is applicable to living humans, it becomes a valuable tool for studying the neurological changes of fiber pathways caused by disorders.

Living with cardiovascular disease often takes a serious emotional toll—and with stress known to worsen heart health, there's growing interest in low-risk, innovative ways to help patients cope. New research from UCLA Health suggests that virtual reality (VR) may offer a promising tool to ease psychological stress and support heart health.

Weight loss continues to dominate public discourse—often framed as a matter of personal responsibility. But after nearly 15 years working in and around health and nutrition research, I've seen how weight is treated differently from almost every other health issue.

Have you ever noticed a sign in a doctor's office saying that you may have to pay extra insurance costs if you discuss additional problems with your physician?

On July 28, 2025, a 27-year-old gunman entered a New York City office building that is home to the National Football League's headquarters. He shot and killed four people and injured one other before killing himself.

Adolescents and young adults with cancer who are navigating life between childhood and early adulthood face a unique set of challenges. Despite overall improvements in cancer survival rates, this group has not experienced the same gains as younger children or older adults. Researchers are working to change that by addressing not just treatment, but also the financial, emotional, and practical barriers that affect care.

Cornell researchers recommend modifications to the recipe for preparing bottles of powdered infant formula to ensure safety against rare foodborne bacteria that can be deadly for high-risk infants, thanks to a new study that analyzed the existing guidelines.

A study from the Texas A&M University School of Public Health sheds new light on the relationship between community cohesion prior to a natural disaster and resilience after one, with possible policy applications for public health and emergency preparedness practitioners.

The digestive system's rhythms are controlled by body clock genes, as well as lesser-known regulators called noncanonical clock regulators. Researchers at Baylor College of Medicine aimed to understand how these additional regulators influence the way digestive organs handle stress. Their comprehensive review was published in Trends in Endocrinology and Metabolism.

Socioeconomic inequalities in children's mental health are already evident by age 5 and persist throughout childhood and adolescence, according to analysis led by researchers from the University of Liverpool.

Artificial intelligence (AI) is becoming a powerful new tool in training and education, including in the field of neurosurgery. Yet a new study suggests that AI tutoring provides better results when paired with human instruction.

New research published in Nature has uncovered powerful evidence that may explain why a new chemical modification of RNA is made in cells.

What is the earliest spark that ignites the memory-robbing march of Alzheimer's disease? Why do some people with Alzheimer's-like changes in the brain never go on to develop dementia? These questions have bedeviled neuroscientists for decades.

Mutations in a single gene, HNF1A, are known to cause MODY3, a rare, early-onset form of diabetes. Smaller-scale mutations in the very same gene are also common and quietly nudge millions of people toward type 2 diabetes. A study published in Cell Metabolism reveals why.

Tay-Sachs and Sandhoff diseases, genetic disorders affecting the brain, have no effective treatment and are typically fatal within the first years of life.

Researchers analyzed the profile of adults who claim to have past-life memories, the features of these memories, and their associations with mental health, happiness, and religiosity/spirituality. The results indicated a high prevalence of mental disorder symptoms, with religiosity and spirituality being protective factors.
