Small dogs tend to age more slowly than large ones, and big dogs might have rogue ‘jumping genes’ that hop around the genome to blame.
The study found that epigenetic changes related to ageing accumulate at a faster rate in big dogs than in small dogs.

Big dogs age faster than little ones — rogue ‘jumping genes’ might be to blame
Study of almost 900 dogs from roughly 120 breeds finds that rapid ageing of large canines is linked to changes in the epigenome.
!["Bann et al. pose the question, ‘why can’t epidemiology be automated (yet)?’, as though the automation of epidemiology is both inevitable and desirable [1]. They describe a future of ‘1-click reviews’ and ‘end-to-end automation’ that will ‘[boost] the efficiency of current practice and … [create] new opportunities for’. But scientific discovery requires far more than increased efficiency. In epidemiology, new knowledge comes from critical reasoning about data, about context, and about the limits of our existing understanding. Such reasoning, in turn, demands deep thought, scholarship, and diligence. All are threatened by automation..."](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:7pr24ntsdnvee23td552aes4/bafkreihsubff7cl2mwukra4tmn3tqqkzrmuzik57g6jmtmt6jftjghfska)
