(Phys.org)—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.
