As recently as the mid-20th century, aging was described by Nobel Prize laureate Peter Medawar as "an unsolved problem in biology." Today, scientists can analyze the activity of thousands of genes in ...

Aging does not arrive all at once. It builds quietly across years, touching cells long before symptoms appear. Scientists have spent decades studying diseases tied to aging. Now, many want to ...

A new Yale study of roundworms, a species with the unique ability to regenerate, reveals that disruptions in the body's internal map of cellular organization may play a part in age-related decline.

New research reveals that cells of the same chronological age can follow dramatically different biological aging paths, offering new insights into cancer, neurodegeneration and the fundamental biology ...

When the four-member crew of Axiom-2 launched into space in May 2023, their 10-day mission was chock full of experiments aimed at understanding human physiology. Results from some of those experiments ...

The most recent issue of Journal of the American Medical Association includes a landmark review highlighting innovative strategies to slow the biological aging process, an emerging approach with ...

Scientists at the University of California San Francisco (UCSF) may have discovered a cause of aging in the brain. The culprit is a protein called ferritin light chain 1 (FTL1), described as an ...

Scientists have discovered that starving and then refeeding worms can reveal surprising secrets about aging. When a specific gene (called TFEB) is missing, these worms don’t bounce back from ...

What do "epigenetic clocks" actually measure? These lab tests have become popular tools for studying biological aging, or how the body's cellular function changes at a faster or slower rate than ...

Diabetes drugs have shown surprising benefits for the heart, kidneys, and brain. Now provocative animal research suggests they may influence the biology of aging itself. New evidence that semaglutide ...
