Scientists have found an extremely subtle twist in the genetics of aging cells, one that seems to make them increasingly less functional as time goes on.
R esearchers from Northwestern University have revealed animals like mice, rats, killifish, and even humans show a gradual imbalance of long and short genes in virtually every cell in their body as they age.
The discovery suggests there aren’t specific genes that control the aging process. Instead, old age seems to be governed by systems-level changes with complex effects. And this can impact thousands of different genes and their respective proteins.
