Study reveals epigenetic adaptation of beta cells across lifespan and disease

As people age, most maintain normal blood sugar even as insulin resistance tends to rise. New research suggests that pancreatic beta cells help meet this demand through gradual epigenetic changes in regulatory regions of the genome that support beta-cell identity and function.

AAD survey reveals Americans ignore sun risks despite skin cancer concerns

The American Academy of Dermatology (AAD) today released results from its annual Practice Safe Sun Survey, revealing many Americans still engage in risky sun behaviors driven by misinformation, social media, and persistent tanning myths despite their concerns about the long term aging effects of sun exposure. In recognition of Skin Cancer Awareness Month (May) and Melanoma Monday® on May 4, the AAD is encouraging the public to practice safe sun to reduce their risk of skin cancer.

AHA calls for lifelong brain health strategy to prevent cognitive decline

The AHA scientific statement calls for a life-course approach to brain health that integrates cognitive, emotional, behavioral, vascular, environmental, inflammatory, sleep, microbiome, and social factors. It highlights how early-life exposures, mental health, pollution, chronic inflammation, poor sleep, gut dysbiosis, and socioeconomic adversity may shape brain resilience and later-life cognitive decline.

Study suggests a U-shaped link between cholesterol levels and mortality among Chinese adults

A new commentary published in Engineering highlights key findings from a large multinational cohort study that re-evaluates cholesterol management for cardiovascular and chronic disease prevention, suggesting a U-shaped association between cholesterol levels and mortality among Chinese adults that challenges the conventional "lower is better" approach.

Emergency settings more likely to initiate risky medications for seniors

Initial prescriptions for medications affecting cognition, such as antipsychotics, are disproportionately likelier to come from acute and post-acute settings such as emergency rooms, hospitals and skilled nursing facilities than they are from doctors' offices, new UCLA research suggests.

AI tool estimates biological age from photos to predict cancer outcomes

The Mass General Brigham research team behind FaceAge, an artificial intelligence (AI) tool that can estimate a person's biological age from a single photo, is reporting in a new study that estimating biological age from multiple photos taken over time can provide even more information about how well a person with cancer will do with treatment.

New scientific statement defines brain health across life

Brain health isn't determined only by genetics or what happens later in life. A growing body of research shows that a range of factors-from mental health and sleep to environment, lifestyle and social conditions-play a powerful role in shaping how the brain functions and ages.
