Aging muscle may help cancer grow

Scientists found that older, weaker muscle releases fewer extracellular vesicles and less of a microRNA called miR-7a-5p. Exercise can restore vesicle release and may help reduce cancer risk in older adults. The work suggests new biomarkers and therapies.

Biological signals that predict lifespan appear in dogs

New research from the Dog Aging Project finds that the same biological signals linked to human lifespan also appear in dogs. The study, published in The Journals of Gerontology, compared dog data with large human studies.

Exercise better than protein powder for older adults' muscle strength

A clinical trial in people aged 65 and over found that extra protein from whey capsules did not increase muscle strength after 24 weeks. Researchers say resistance exercise remains the most reliable way to improve strength.

Blood cell aging linked to mood symptoms of depression

A study found that a marker of biological aging in certain white blood cells relates to mood and cognitive symptoms of depression, but not to physical symptoms. The research used blood tests from women with and without HIV.

Being Overweight May Speed Brain Decline

A long US study found that higher body mass index (BMI) over time is linked to faster decline in memory, thinking and other brain skills. The effect was strongest after several years and in older adults.

Vigorous exercise helps sleep in older adults with mild cognitive impairment

A small Texas A&M study used Oura Rings to track seven older adults with mild cognitive impairment for 14 days. Vigorous exercise gave the largest sleep benefit; light activity helped a little and moderate exercise showed no clear effect.

How coffee compounds may protect the body

New research from Texas A&M suggests a receptor called NR4A1 helps explain coffee’s links to lower disease and longer life. Scientists found some coffee compounds bind NR4A1 and reduce cell damage in laboratory models.

Nasal spray reverses signs of brain aging in models

Researchers developed a nasal spray that delivers extracellular vesicles with microRNAs to the brain. In preclinical models it reduced inflammation, restored neuronal mitochondria and improved memory, but human tests are still needed.

QR codes and older adults in hospitality

Research from the University of South Florida shows older adults have mixed reactions to QR codes for menus and services. Hard-to-use codes increase frustration and can reduce satisfaction and loyalty; printed options remain important.

Heart disease risk linked to fractures after menopause

A study of more than 21,000 postmenopausal women found higher cardiovascular risk is linked to more fractures, especially hip breaks. The PREVENT score (2024) helped predict which women had greater fracture risk.

Neighborhoods and cellular aging

A study of American adults found that living in low-opportunity neighborhoods is linked to higher levels of a cellular aging marker, CDKN2A RNA. The link was strongest for social and economic neighborhood factors.

Smoking may speed eye aging and lead to AMD

A new study shows cigarette smoke can accelerate aging in retinal cells and may help cause age-related macular degeneration (AMD). Researchers used experiments in mice and tests of donated human eye cells to find shared gene changes.

Blood piRNAs predict short-term survival in older adults

A study led by Duke Health found that small RNA molecules called piRNAs in blood can predict two-year survival for people aged 71 and older. A simple blood test may help identify short-term risk.
