science π¬ Maternal age link to lifespan isn't DNA damage
Research at the Marine Biological Laboratory found that advanced maternal age affects offspring via epigenetic switches, not DNA damage. This was observed using rotifers in a comparative study conducted by a team led by Kristin Gribble on the 19th. The study showed negative effects can fully reverse in just one generation, and some offspring even lived longer. Researchers are now checking if mitochondrial DNA transmits this maternal age info. This provides key data for personalized medicine, though human studies are still needed. π§¬
