Mom’s Age Shapes Kids—But It’s Reversible | Science News
Scientists are uncovering that a mother’s age can leave a reversible biological imprint on her offspring—not by altering DNA, but by tweaking how genes are expressed. Using rotifers as a model, researchers found these epigenetic changes, possibly mediated by histones, can vanish in just one generation, challenging the idea of inherited damage. It’s not about broken hardware (DNA), but software updates (gene activity)—and those updates can be reset. This flips the script on generational health, suggesting our biology is far more dynamic than previously thought, with ancestral experiences…
