Researchers at the University of Florida report that lifestyle factors such as optimism, good-quality sleep and strong social support are linked to brains that appear as much as eight years younger than expected for a person’s age. The effect was observed even among adults living with chronic pain, underscoring how everyday behaviors may influence brain health over time.
The American College of Sports Medicine has released an updated Position Stand on resistance-training prescription for healthy adults, its first update since a 2009 Position Stand. The document is based on an overview of 137 systematic reviews covering more than 30,000 participants and concludes that even small amounts of regular resistance training can improve strength, muscle size, power and physical function.

Researchers at Mayo Clinic have developed an aptamer-based technique to tag senescent, or so‑called “zombie,” cells in living mouse tissues, work they say could eventually support targeted therapies for age‑related diseases. The project grew out of a chance conversation between two graduate students, according to Mayo Clinic.
Researchers at the University of Basel have discovered that specific RNA molecules in nematodes' diets trigger a mild stress response that enhances cellular health and extends healthspan. This process prevents toxic protein buildup associated with aging and diseases like Alzheimer's and Parkinson's. The findings, published in Nature Communications, suggest diet influences how well organisms age.
