If I use SPF50+ sunscreen every day do I need to take vitamin D?

Asking people to imagine future regret could be a powerful tool for increasing flu vaccination rates, according to new research from SMU.

A study led by UC San Francisco and UC Davis has concluded that radiation from medical imaging is associated with a higher risk of blood cancers in children.

Thousands of people with dementia are prescribed powerful medications for longer and at higher doses than recommended, raising concerns about safety and quality of care, finds a new study led by UCL researchers.

Thanks to in-utero blood transfusion technology, what was once a fatal diagnosis in the womb can now result in live births. However, this medical advancement created a new challenge: a growing population of children born with that diagnosis—the severe, inherited blood disorder alpha thalassemia—which requires lifelong specialized care.

This year, 10 days of extreme heat in Europe killed roughly 2,300 people, severe flooding on the New South Wales coast left more than 48,000 stranded, and wildfires in Los Angeles destroyed at least 16,000 homes and other buildings.

As a clinician and researcher in cardiac rehabilitation, I've learned that the most important tool in our work is not a stethoscope or a treadmill—it is our ability to listen. Not just to the words patients say, but to the nuances of their experiences, fears, and hopes after a heart event. Listening carefully is what allows us to understand recovery in a holistic way, and it is at the heart of qualitative research in health care.

If you could, would you pay to live forever? Some Silicon Valley billionaires aren't just making tech products—they've set their sights on immortality.

A multidisciplinary team has used advanced imaging and computational modeling to analyze the "crosstalk" between neurons and their supporting glial cells in the human brain. This approach highlights the brain's interconnected cellular network.

Apple has announced a package of health features, alongside the launch of the new Apple Watch Series 11, including an alert that the wearer may have high blood pressure, also known as hypertension.

Colorectal cancer remains a leading cause of cancer death, with incidence rising among older adults. One of the most pressing clinical questions has been whether elderly patients should receive oxaliplatin, a standard component of adjuvant chemotherapy that is known to cause serious side effects.

The investigational drug elinzanetant significantly reduces hot flashes and night sweats for postmenopausal women, a large, international clinical trial has found.

More than a third of the world's population is affected by metabolic dysfunction-associated steatotic liver disease, or MASLD, the most common chronic liver disease in the world.

A brain imaging technique developed by Columbia researchers has identified areas in the brain's cerebral cortex—just behind the forehead—that are most damaged by the repetitive impacts from heading a soccer ball. Their study also found that the damage leads to cognitive deficits seen in soccer players who head the ball frequently.

A new study, led by researchers at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, captured details of glioblastoma that had never before been seen and revealed a surprise finding: Glioblastoma cells that "cluster" together with other cells of the same type are less deadly than those that disperse from these clusters. The findings were also corroborated in breast cancer samples and point to a possible new general principle of solid tumor biology.

Twenty-seven species of bacteria and fungi among the hundreds that live in people's mouths have been collectively tied to a 3.5 times greater risk of developing pancreatic cancer, a study led by NYU Langone Health and its Perlmutter Cancer Center shows.

Taking vitamin D2 might lower the body's levels of the more efficient form of vitamin D, vitamin D3, according to new research from the University of Surrey, John Innes Center and Quadram Institute Bioscience. Many people take vitamin D supplements to support their bone and immune health and meet the UK government recommendation of 10 micrograms (µg) each day, especially during the winter months.

The impact of chronic conditions on human health has become a research topic of growing focus in recent years. The prevalence of individuals living with two or more chronic diseases at the same time, combined with an aging population, has placed growing demands on the U.S. health care system.

A team led by Christian Baumgartner of the Institute of Health Care Engineering at Graz University of Technology (TU Graz) has developed a highly detailed digital twin of the A549 lung cancer cell line. The twin builds on bioelectric processes and calcium dynamics in the cell interior in innovative new ways.
