Scientists have found that a stress response in cells, when 'switched on' at a post-reproductive age, could be the key to slow down ageing and promote longevity.

Black adults treated at advanced heart failure centers received potentially life-changing therapies, such as transplants and heart pumps, about half as often as white adults, possibly due to racial bias, a small National Institutes of Health-supported study has found. Researchers followed 377 patients receiving treatment at one of 21 centers in the United States and found that 62 of 277 white adults (22%) received a heart transplant or ventricular assist device (VAD), a mechanical device that pumps blood for the heart. In comparison, 11 of 100 Black adults (11%) received these end-stage heart failure therapies, which can extend and improve a patient’s quality of life.

A new highly selective PET imaging agent can detect the presence of overexpressed monoamine oxidase-B (MAO-B) in cognitively unimpaired individuals with high beta amyloid -one of the earliest signs of Alzheimer's diseas-according to new research. The radiotracer, 18F-SMBT-1, allows for a better understanding of the role of inflammation in Alzheimer's disease, which can enable more accurate staging and prognosis at earlier stages.

In a series of experiments using functional magnetic resonance imaging (fMRI) to measure brain activity across networks in the brain, researchers looked at how stress might increase appetite in obese and lean adults.

Smooth, foamy, water-proof. These characteristics are extremely desirable in beauty products, but manufacturers sometimes use ingredients that contain fluorine -- including potentially harmful per- and polyfluoroalkyl substances (PFAS) -- to achieve them. Now, researchers show that some cosmetics and personal care products labeled as having fluorinated components also contain PFAS, whether or not these 'forever chemicals' were listed as ingredients.
Beauty products with fluorinated ingredients may also contain PFAS, study reports

A bacterial protein called BefA disrupts cell membranes -- and this disruption makes vital insulin-producing cells in the pancreas reproduce early in development. The finding points to a possible way to bolster this cell population, protecting against Type 1 diabetes.
