Aging Brain May Adapt to Decode Tricky Social Cues

New research shows that older adults may compensate for age-related cognitive decline by enhancing activity in a specific brain region linked to attention—the locus coeruleus (LC). In a brain imaging study, older participants showed stronger LC responses when interpreting ambiguous facial expressions, compared to younger adults.

Brain Scan Predicts Dementia Risk and Aging Speed in Midlife

A new tool developed by researchers can estimate how fast someone is aging by analyzing a single MRI brain scan, predicting chronic disease risk and dementia years before symptoms appear. Unlike traditional “aging clocks,” this model was trained using longitudinal data from the same individuals, eliminating generational biases.

Regular Sex May Ease Painful Menopause Symptoms

A new study reveals that women who engage in regular sexual activity experience fewer symptoms of genitourinary syndrome of menopause (GSM), such as vaginal dryness, irritation, and pain. In a survey of over 900 women aged 40 to 79, researchers found that while sexual desire and lubrication declined with age, orgasm and satisfaction remained stable.

Staying Active Slows Cognitive Decline

Regular physical activity isn’t just good for the body—it protects the brain as we age. A 16-year study of over 13,000 adults found that sustained physical activity significantly slowed cognitive decline.

Aging Spreads Through the Bloodstream

New research reveals that aging isn't just a local cellular process—it can spread throughout the body via the bloodstream. A redox-sensitive protein called ReHMGB1, secreted by senescent cells, was found to trigger aging features in distant tissues, impairing regeneration and muscle function.

Caffeine Gives Cells an Energy Boost Against Aging

New research shows that caffeine may help slow ageing at the cellular level by activating AMPK, a key energy-sensing pathway. Using fission yeast as a model for human cells, scientists found that caffeine boosts AMPK activity, which helps cells manage stress, repair DNA, and regulate growth.

Wellbeing May Help Protect Memory in Middle Age

A new 16-year study of over 10,000 adults finds that higher wellbeing is linked to better memory performance in middle age. Researchers tracked participants' psychological wellbeing and memory recall, finding that those with higher life satisfaction were more likely to retain stronger cognitive function over time.

Brain Age Gap May Predict Cognitive Decline

A new study reveals that the brain age gap—the difference between a brain’s biological age and chronological age—may influence how risk factors like diabetes and high blood pressure affect cognitive function. Using machine learning to analyze brain scans from over 1,400 older adults, researchers found that a greater brain age gap was linked to poorer thinking and memory skills.

Alzheimer’s Risk Linked to Increased Social Activity, Not Isolation

Contrary to popular belief, a new study suggests that people with a higher genetic risk for Alzheimer’s may become more socially engaged—not less. Researchers analyzed data from over 500,000 individuals and found that higher-risk participants reported lower social isolation and more positive family interactions.

Healthy Habits May Offset Brain Aging Linked to Shorter Telomeres

New research shows that healthy lifestyle choices can reduce the risk of stroke, dementia, and depression—even in people with biologically shortened telomeres. Telomeres are protective DNA caps that naturally shrink with age and environmental stress, increasing vulnerability to age-related brain diseases.

Skin Aging Reduced by Molecules from Bacteria in the Blood

Researchers have identified three anti-aging compounds produced by Paracoccus sanguinis, a bacterium found in the bloodstream. These indole-based metabolites reduced inflammation and oxidative stress in human skin cell cultures—key contributors to skin aging.

Facial Stimulation Clears Brain Waste and Boosts Aging Minds

Researchers have discovered a safe, non-invasive way to enhance the brain’s waste clearance system by mechanically stimulating lymphatic vessels just beneath the facial skin. This gentle technique significantly improves cerebrospinal fluid (CSF) drainage—a critical function that declines with age and contributes to cognitive disorders like Alzheimer’s.
