Teen attitudes toward sun protection impact skin cancer prevention behaviors

A new study funded by the National Cancer Institute at the National Institutes of Health finds that how high school students perceive the costs of sun protection and the rewards of tanning play a significant role in whether they practice sun-safe behaviors.

Calcium signals in microglia drive anxiety and compulsive behaviors

Researchers had previously discovered a population of immune cells within the brain that can act as accelerators and brakes for anxiety in mice. N

Study links cognitive worries in Parkinson’s to anxiety and depression

For many individuals living with Parkinson's disease and those in its "prodromal" or early stages before movement impairment, there is a distressing gap between how they feel their brain is working and what clinical tests show.

Morning naps may flag higher mortality risk in older adults

Older adults who took longer and more frequent daytime naps, especially in the morning, had a higher risk of all-cause mortality in this prospective cohort study using actigraphy-based nap tracking. Variability in nap duration from day to day was not associated with mortality after full adjustment.

Cancer-linked mutations in the brain cells may drive Alzheimer’s disease

As the body ages, cells naturally accumulate dozens of genetic mutations each year. New research from Boston Children's Hospital, published in Cell, finds that the brain's resident immune cells, microglia, amass mutations in specific cancer-driving genes yet they don't manifest as cancer.

Microglia actively shape glioblastoma growth and tumor spread

Glioblastoma, the most common and most aggressive brain tumor type in adults, remains difficult to treat because it can infiltrate surrounding brain tissue and spread far beyond the main tumor.

Cognitive decline may signal heart trouble years before a cardiovascular event

In a large ASPREE and ASPREE-XT nested case-control study of older adults without prior cardiovascular disease, people who later experienced a CVD event showed faster cognitive decline beginning roughly 3 to 8 years before the event. Processing speed declined earliest, suggesting that subtle cognitive changes may emerge well before overt cardiovascular disease.

Real-time tracking reveals gaps in recalled alcohol use symptoms

When young adults are asked to recall their drinking habits, their recollections may not always match what actually happened in their day-to-day lives, a new study suggests.

Gut microbiome clues may help spot Parkinson’s disease in its earliest phase

Researchers found that a Parkinson’s disease-related gut microbiome pattern appears not only in people with diagnosed Parkinson’s, but also in some non-manifesting GBA1 variant carriers and a subset of healthy individuals. The findings suggest that gut microbiome changes may help flag people who are closer to Parkinson’s disease development, although longitudinal studies are still needed to confirm predictive value.

Why do the deadliest cancers still get less NIH research funding?

Researchers found that NIH funding for major US cancers does not consistently align with lethality, with highly fatal cancers such as pancreatic cancer and small-cell lung cancer receiving far less funding per estimated death than breast or prostate cancer. The study argues that incidence alone is not enough and that funding decisions should better incorporate mortality, survival, and mortality-to-incidence ratios.

Chronic wildfire smoke exposure may raise long-term cancer risks

Exposure to wildfire smoke was associated with a significantly increased risk of lung, colorectal, breast, bladder, and blood cancer, according to results from a study presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, held April 17-22.

Early myocarditis onset after immunotherapy linked to higher fatality risk

Patients who developed myocarditis within the first month of receiving immune checkpoint inhibitor therapy were more likely to die of myocarditis, and myocarditis-specific fatality was more common in patients who experienced co-occurring myositis and myasthenia gravis, according to results from a study presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, held April 17-22.

Millions of Americans with hepatitis C still remain untreated, analysis reveals

Millions of Americans are still battling potentially deadly hepatitis C even though they could be cured with antiviral drugs they are not receiving, a new analysis reveals.

Common gene in axolotls, mice and zebrafish may unlock human limb regrowth

Investigating a common gene in three very different species – axolotls, mice and zebrafish – scientists have discovered the potential for a novel gene therapy aimed at eventually regrowing limbs in humans, according to new research published this week.
