A 24-year analysis of 1,712 adults from the Atherosclerosis Risk in Communities (ARIC) study reveals that the impact of sedentary behavior on brain health depends heavily on the activity performed. Research published in the journal Alzheimer’s & Dementia indicates that while television watching is associated with reduced brain volumes and increased vascular markers, occupational sitting … Read more
Neuroscientist Karyn Frick, a professor of psychological and brain sciences at the University of Wisconsin-Milwaukee, is leading research into how estrogens regulate memory, aiming to create new treatments for age-related memory loss and dementia. By studying sex-based differences in neurobiology, Frick’s work seeks to address why middle-aged females often experience more significant memory decline than … Read more
Epigenetic clocks—tools designed to measure biological age through DNA methylation—capture distinct, non-overlapping biological processes rather than a single universal aging mechanism. According to a study published in npj Aging, researchers have developed Transcriptomic Aging Gene Scores (TAGS) to better interpret these clocks, showing that gene expression patterns often predict health outcomes like mortality and frailty … Read more
Moderate daily movement—roughly 3,000 steps—may significantly slow cognitive decline and protect brain health in older adults, according to research published in Nature in November 2025. While the activity does not clear amyloid plaques often targeted by Alzheimer’s medications, it appears to inhibit the accumulation of tau proteins, which are more directly linked to memory loss … Read more
Stanford Medicine researchers have identified a primary driver of biological aging: the failure of tissue-resident macrophages to clear senescent, or “zombie,” neutrophils from the body. According to a study published July 16 in Science, blocking a specific pro-inflammatory receptor, EP2, on these immune cells rejuvenated organ function and reduced age-related frailty in mice. This discovery … Read more
Senescent cells—damaged cells that stop dividing but remain metabolically active—accumulate lipid droplets as a hallmark of their aging state, according to a study published July 1, 2026, in the journal Aging. Researchers led by Noa Rachmian-Cooper and Valery Krizhanovsky at the Weizmann Institute of Science found that these lipid deposits are linked to chronic inflammation … Read more
Healthy aging may depend less on expensive supplements and more on the consistent rejection of comfort, according to Dr. Stephanie Rogers, a geriatrician. By embracing hormesis—the biological principle of using small, manageable doses of stress to trigger beneficial adaptations—individuals can build physical and cognitive resilience that supports long-term health, though experts emphasize this complements, rather … Read more
Regularly sleeping nine to 10 hours or more per night is linked to higher levels of p-tau181, a blood-based protein marker for Alzheimer’s disease, according to a study from UT Health San Antonio. Researchers found that the association becomes most pronounced beyond 10 hours of sleep, suggesting long sleep may be an early indicator of … Read more
Age-related declines in face recognition are associated with a reduction in eye-movement consistency, according to a study published in npj Science of Learning. Researchers found that while older adults retain the visual scanning routines developed earlier in life, their ability to execute these patterns consistently diminishes. This loss of predictability, linked to declines in selective … Read more
Aging well is defined not by the absence of disease, but by the ability to maintain functional independence and physical resilience during the critical transition of the 40s and 50s. According to Dr. Tina Sadarangani, a geriatric nurse practitioner, and Dr. Emmanuel Osei-Boamah, a board-certified geriatrician, health outcomes in later life are directly influenced by … Read more
