A new map of the tiny DNA changes we all collect as we grow

Every cell in your body carries a slightly different genome, edited by small mutations picked up across a lifetime — and until now that variation was nearly impossible to measure. The SMaHT Network, reporting in Cell, has benchmarked new DNA-sequencing methods and produced the first body-wide map of this quiet variation. That baseline of 'normal' is the reference scientists need before they can spot where such changes feed into development, ageing and disease.
