Study reveals unexpected link between cell membrane damage and cellular senescence

Our cells are surrounded by a fragile membrane that's only 5 nanometers thick, 1/20 of a soap bubble. Cells are easily damaged by physiological activities, including muscle contraction and tissue injury.

Study reveals novel mechanism for longevity of oocytes

Oocytes are immature egg cells that develop in almost all female mammals before birth. The propagation of future generations depends on this finite reserve of cells surviving for many years without incurring damage.
