Lifelong Social Bonds Can Slow Biological Aging at the Cellular Level

A new study shows that lifelong social advantages—from early parental warmth to adult friendships and community support—can slow biological aging. Researchers analyzed over 2,100 participants and found that those with stronger, more consistent social connections had younger biological ages according to epigenetic clocks GrimAge and DunedinPACE.

Lifestyle Changes Show Power to Prevent Alzheimer’s

A growing body of research underscores that Alzheimer’s and cognitive decline are not inevitable parts of aging. Lifestyle interventions targeting exercise, diet, social engagement, and cognitive stimulation have been shown in large clinical trials to improve brain function and slow decline.

Attention and Focus Abilities Peak Between Ages 27 and 36

Researchers analyzed 139 neuroimaging studies spanning ages 5 to 85 to map the brain’s activity in cognitive control. They found an inverted U-shaped lifespan trajectory, with brain activity rising through adolescence, peaking between ages 27 and 36, and then gradually declining.

The Midlife “Unhappiness Hump” Has Vanished, But at a Cost

A new large-scale study finds that the long-observed “unhappiness hump,” where mental distress peaked in midlife, has disappeared. Instead, younger people now report the highest levels of anxiety, depression, and stress, with ill-being declining across the lifespan.

Elderly Positivity Bias May Signal Early Cognitive Decline

New research suggests that the tendency of older adults to misinterpret neutral or negative emotions as positive may be a warning sign of cognitive decline. In a study of 665 participants, positivity bias was associated with poorer cognitive performance but not with emotional decline such as depression.

Education Gap Is Speeding Up Aging in Millions of People

A new study reveals that Americans with less education are aging faster than those with more schooling, and the divide has widened over the past three decades. Biological age—measuring internal health rather than years lived—shows that people with a college degree experience slower aging.

Long-Term Nicotine Use Delays Aging-Linked Motor Decline

A new study demonstrates that long-term oral nicotine administration reprograms aging-related metabolism and slows motor decline in mice. By targeting the sphingolipid-energy axis, nicotine improved energy homeostasis, preserved gut microbial diversity, and supported neuromuscular resilience.

400 Genes Identified as Key Drivers of Aging

A massive genetic study has identified more than 400 genes that drive different forms of unhealthy aging, from cognitive decline to metabolic problems. The findings show that frailty is not a single condition but multiple subtypes with distinct biological pathways.

Blocking Protein Reverses Age-Related Memory Loss

Aging disrupts memory by increasing levels of the protein FTL1 in the hippocampus, new research shows. In mice, excess FTL1 caused neurons to grow abnormally and led to memory decline, while reducing FTL1 reversed these impairments.

Why the Blood-Brain Barrier Weakens With Age

A new study has uncovered why the blood-brain barrier — the brain’s protective shield — becomes leakier with age, potentially triggering memory decline. Researchers identified that proteins N-cadherin and occludin, which help maintain the barrier’s tight junctions, decrease over time.

Why Some 80-Year-Olds Have the Memory of 50-Year-Olds

For 25 years, scientists have studied “SuperAgers”—people aged 80 and above whose memory rivals those decades younger. Research reveals that their brains either resist Alzheimer’s-related plaques and tangles or remain resilient despite having them.

Living Near the Ocean May Add Years to Your Life

A new study shows that living near the ocean may be linked to a longer life—while living near inland rivers or lakes in urban areas may actually shorten it. Researchers analyzed data from over 66,000 U.S. census tracts and found coastal residents live, on average, at least a year longer than the national average.
