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.

Atlas maps how aging reshapes cells

Scientists at Rockefeller University profiled nearly 7 million cells from 21 organs in mice at three ages. The atlas reveals cell-type shifts, coordinated changes across organs, strong sex differences and genomic sites linked to immunity.

Older adults more exposed to low-credibility online health information

Researchers at the University of Utah tracked web activity of more than 1,000 US adults for four weeks. They found low-credibility health sites were rare overall but visits were concentrated among older adults, especially those who lean right politically.

Speed training may lower dementia risk in older adults

A long-term randomized study found that adults 65 and older who completed speed-of-processing training, with later booster sessions, were less likely to be diagnosed with dementia up to twenty years later.

Worry About Aging Linked to Faster Biological Aging in Women

A study found that women who worry about getting older tend to show faster biological aging in blood tests. The link was strongest for worries about declining health and weakened after accounting for smoking and alcohol.

Hidden RNA aging clock found in human sperm

Researchers at University of Utah Health discovered an RNA “aging clock” in sperm. Using PANDORA-seq, they found age-related RNA changes in mice and humans and showed these RNAs can alter early embryo cells.

Cancer survivors may age faster

A new study finds that adolescent and young adult cancer survivors show faster biological and brain aging than peers. The research links faster aging to memory and attention problems and tests ways to help survivors.

Low pesticide exposure speeds aging in fish

Researchers found that long-term exposure to low levels of a common agricultural insecticide caused faster physiological aging and shorter lifespans in wild and laboratory fish. The study links telomere shortening and lipofuscin buildup to chlorpyrifos exposure.
