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.

Youthful Blood Restores Aging Retina and Vision

Researchers demonstrated that systemic factors from young mice can rejuvenate the aging retina by alleviating cellular senescence and restoring function. Using heterochronic parabiosis and single-cell RNA sequencing, the study identified AdipoR1 and its downstream AMPK signaling as key drivers of retinal rejuvenation.

Study Reveals Biological Bias in Baby Boy or Girl Odds

A massive study of over 58,000 women shows that families may have their own subtle biological bias toward having boys or girls, rather than offspring sex being purely random. Researchers found that older maternal age at first birth and specific maternal genetic variants were linked to having only sons or only daughters.

Eating Eggs May Help Lower Alzheimer’s Risk

A large cohort study of older adults found that eating at least one egg per week was linked to a significantly lower risk of Alzheimer’s dementia. Participants who consumed eggs more frequently also showed less Alzheimer’s-related pathology in their brains at autopsy.

Tiny Brain Region Orchestrates How We Segment and Remember Life Events

Our memories don’t flow like a continuous stream—they’re divided into meaningful events, thanks to a tiny brain region called the locus coeruleus. New research shows this region acts like a “reset button,” activating at event boundaries to signal the hippocampus to store distinct memories.

Playing Music Helps Older Brains Stay Sharp

Long-term musical training may help older adults maintain youthful brain patterns and better speech perception in noisy environments, according to new research. Scientists found that older musicians showed more efficient brain connectivity and better performance than non-musicians of the same age.

Middle-Age Clues: Blood Biomarkers Signal Alzheimer’s Risk Early

New research shows that signs of Alzheimer’s disease can already be detected in the blood of people as young as their 40s. Finnish scientists found elevated Alzheimer’s-related biomarkers in middle-aged adults, especially among those with maternal history or kidney disease.

Blood Sugar, Not Age, Drives Sexual Health Decline in Men

A new study reveals that metabolic health, particularly modest increases in blood sugar, plays a bigger role than age or testosterone in declining sexual and reproductive function in men. Researchers tracked 117 healthy men over six years, assessing hormones, semen quality, erectile function, and blood sugar.

Study Challenges Link Between Football and Brain Protein Buildup

A new study questions whether playing youth football leads to harmful protein buildup in the brain. Researchers examined 174 donated brains, including former high school and college players, and found no link between contact sports and excess tau protein in a key memory region.

Psilocybin Shows Promise as Anti-Aging Therapy

Psilocybin, the active compound derived from psychedelic mushrooms, significantly delayed cellular aging and extended lifespan in a preclinical study. Researchers observed a 50% increase in the lifespan of human skin and lung cells and a 30% increase in survival in aged mice treated with psilocybin.

Anxious Mondays Leave Lasting Mark on Stress

A new study reveals that anxiety felt on Mondays uniquely elevates stress hormones, even in retirees, with potential consequences for heart health. Researchers found older adults who reported Monday anxiety had 23% higher long-term cortisol levels than peers anxious on other days.
