Public health guidelines for protein intake and exercise are increasingly viewed as insufficient for maintaining long-term health, according to a perspective paper published in Frontiers in Nutrition. Dr. Chris Macdonald, a Fellow at Lucy Cavendish College, University of Cambridge, argues that current standards prioritize the prevention of deficiency rather than optimizing strength, mental sharpness, and … Read more
The Bacillus Calmette-Guérin (BCG) vaccine, typically used to prevent tuberculosis, may remodel the brain’s immune environment to potentially lower Alzheimer’s disease risk, according to research published in Communications Medicine. A year-long study led by Mass General Brigham investigators found the vaccine increased immune cell responsiveness and altered Alzheimer’s-related biomarkers in older adults without pre-existing pathology. … Read more

University of Arizona researchers have developed an experimental drug, XL20, that shows potential to protect nerve cells from damage associated with amyotrophic lateral sclerosis (ALS). According to a study published in Nature Aging, the drug targets a specific region of the TDP-43 protein to prevent toxic clumping, a process that contributes to neurodegeneration in ALS … Read more
Researchers have identified blood metabolic pathways that link diet and physical activity to better cognitive and physical function in aging adults. According to a study in Scientific Reports, these lifestyle-modulated metabolic pathway scores (LMPS) correlate with improved mobility, cognition, and independence across the spectrum from healthy aging to Alzheimer’s disease. How do diet and exercise … Read more
Women who have used hormonal birth control or menopausal hormone therapy (MHT) show structural brain differences associated with healthier aging, according to research published in the journal NeuroImage. A study of 459 women aged 65 to 80 found that lifetime exposure to these hormones correlates with greater gray matter volume and cortical thickness in brain … Read more
Centella asiatica, often called tiger grass, is emerging as a primary trend in global skincare due to its proven anti-inflammatory and collagen-stimulating properties. According to Dr. Amy Bandy, a board-certified plastic and reconstructive surgeon, the botanical contains bioactive compounds that repair the skin barrier, while Dr. Olga Bachilo, founder of Glamour Plastic Surgery and Med … Read more
A plant-forward, low-protein diet supplemented with precise amounts of the amino acid methionine increases healthspan and reduces frailty in mice, according to a study published in Cell Metabolism by researchers at the University of Southern California (USC). Led by Valter Longo of the USC Leonard Davis School of Gerontology, the team found that balancing specific … Read more
Long-standing psychological traits, including neuroticism and a lack of purpose, track distinct molecular pathways in Alzheimer’s dementia, according to a multi-omics study published in Translational Psychiatry. Researchers from the Religious Orders Study (ROS) and the Rush Memory and Aging Project (MAP) found that while traditional pathology and genetic risk factors identify overall disease susceptibility, these … Read more
Researchers have identified a decline in the PRDM16 protein as a primary driver of cardiac aging, according to a study published in Science Advances. By analyzing 442,239 single nuclei from human heart tissue, the team mapped how cellular balance shifts from fetal development through age 75. Restoring PRDM16 levels in aged mouse models improved heart … Read more
Immune aging, or immunosenescence, triggers a decline in the body’s ability to fight infections and tumors while simultaneously increasing the risk of chronic inflammation and autoimmune diseases. According to a review published in the Journal of Clinical Investigation, the human immune system reaches a critical inflection point around age 50, where molecular signatures of aging … Read more
