Cognitive Training Can Elevate Brain Chemistry in Aging, NPR Reports
Groundbreaking Findings in Cognitive Training A recent NPR-backed study reports what researchers have long suspected but could only recently demonstrate with compelling evidence: targeted cognitive training can increase the levels of a brain chemical that tends to decrease as people grow older. Over a 10-week period, participants engaging in structured cognitive exercises showed measurable boosts…

Cognitive Training Boosts Brain Chemical That Declines with Age, Study Finds
Overview: A Glimpse into Brain Chemistry and aging For years researchers have warned that certain brain chemicals tend to wane as we get older, potentially impacting memory, attention, and overall cognitive vitality. A new 10-week study provides the most compelling human evidence to date that cognitive training can boost a key brain chemical that typically…

Cognitive Training Boosts Brain BDNF in Aging Adults
New evidence connects cognitive training with higher brain BDNF in older adults A recent 10-week study reported by NPR’s Short Wave program provides the first compelling human evidence that cognitive training can raise levels of brain-derived neurotrophic factor (BDNF), a chemical central to brain plasticity and health. The finding supports decades of animal research suggesting…

Grey Hair May Signal Lower Skin Cancer Risk: New Study Suggests Protective Link
Grey Hair and Melanoma Protection: What the Study Suggests Grey hair is commonly viewed as a marker of aging, but a new line of research is exploring a surprising potential benefit: a possible link between grey hair and a reduced risk of melanoma, the deadliest form of skin cancer. Scientists are investigating whether the body’s…

Grey Hair Could Signal Lower Skin Cancer Risk, New Study Finds
Grey Hair as a Possible Indicator of Melanoma Protection What if the common sign of aging — grey hair — could also reveal something hopeful about our immune defenses? A recent study highlighted by Women’s Health suggests that grey hair might be more than a cosmetic change; it could be a marker of the body’s…

A Sewing Circle, a Home, a Lifeline: The Community Under Threat as Older People’s Homes Are Torn Down
A sewing circle, a home, a lifeline In many communities, the local sewing circle is more than a hobby; it is a social lifeline for older residents. It’s where neighbors share stories, repair garments, and reinforce the everyday rhythms that keep a street feeling like home. Yet in a wave of redevelopment, these intimate social…

Elevated DNA Damage in Short-Sleeping Mexican Cavefish Without Visible Aging Signs
Overview: When Sleep Meets Genetics in a Special Fish Sleep is a universal behavior across the animal kingdom, serving crucial roles in memory, metabolism, and cellular maintenance. A remarkable line of research now turns its attention to the Mexican cavefish (Astyanax mexicanus), a species adapted to perpetually dark, resource-scarce environments. In these cave-dwelling populations, scientists…

Short-Sleeping Mexican Cavefish: DNA Damage Without Aging Signs
Introduction Sleep is a fundamental behavior across the animal kingdom, shaping metabolism, learning, and longevity. A surprising line of inquiry has emerged from the study of the Mexican cavefish, Astyanax mexicanus, a species split between surface-dwelling and cave-dwelling populations. In particular, some cave populations exhibit markedly reduced sleep. Recent research now reveals a striking paradox:…

Short-Sleeping Mexican Cavefish Show Elevated DNA Damage Without Apparent Aging
Overview: A surprising link between sleep, DNA damage, and aging In an intriguing twist on the sleep–aging paradigm, researchers studying the Mexican cavefish (Astyanax mexicanus) have observed elevated DNA damage in individuals that sleep significantly less than their surface-dwelling relatives. Despite the uptick in DNA lesions, these short-sleeping cavefish do not exhibit the typical hallmarks…

Psychological Resilience: The Cornerstone of Longevity in Seniors
Introduction: Why Resilience Matters in Aging As populations around the world live longer, the question isn’t just how long seniors live, but how well. A growing body of research points to psychological resilience—the ability to adapt to stress, bounce back from setbacks, and maintain a positive outlook—as a critical determinant of healthy aging. When resilience…
