Aging Cells Lose Their Grip on DNA Rogues, Brown University Study

Transposable elements are mobile strands of DNA that insert themselves into chromosomes with mostly harmful consequences. Cells try to keep them locked down, but in a new study, Brown University researchers report that aging cells lose their ability to maintain this control. The result may be a further decline in the health of senescent cells and of the aging bodies they compose.
