Most older adults say they’ve experienced ageism, but majority still hold positive attitudes toward aging, poll finds

More than 80% of older adults in a new poll say they commonly experience at least one form of ageism in their day-to-day lives. Many say they routinely experience three or more forms, and these older adults were much more likely to have poor mental and physical health. But despite all this, the poll also suggests that most older adults hold positive attitudes toward aging.

A deep dive into cellular aging

Scientists at Sanford Burnham Prebys Medical Discovery Institute and Harvard University have discovered that mitochondria trigger senescence, the sleep-like state of aged cells, through communication with the cell’s nucleus—and identified an FDA-approved drug that helped suppress the damaging effects of the condition in cells and mice. The discovery, published in Genes & Development, could lead to treatments that promote healthy aging or prevent age-associated diseases such as cancer, Alzheimer’s disease, heart disease and more.
