Although the gut renews itself constantly, its stem cells accumulate age-related molecular changes that quietly alter how ...

Based on new brain mapping research, scientists have discovered that not all cell types in the brain age in the same way. They found that some cells, such as a small group of hormone-controlling cells ...

The brain plays a big part in the aging process, and scientists think they’ve pinpointed the specific cells that control it. In a study of mice, researchers at the Allen Institute identified certain ...

Hair loss and graying, the earliest visible hallmarks of skin aging, result from the functional decline of hair follicle stem ...

Scientists are no longer just cataloging the damage that comes with age, they are starting to rewire the machinery inside cells that makes that damage accumulate in the first place. A new wave of work ...

Aging used to be treated as inevitable—something that just happened with time. But modern science is flipping that narrative, and one molecule keeps showing up at the center of the conversation: NAD+.

NIH-funded mouse study provides roadmap for how aging may alter brain cell genetic activity Based on new brain mapping research funded by the National Institutes of Health (NIH), scientists have ...
