Large dog ageing research and related science news: a short briefing article that previews recent studies linking genome activity to breed-size ageing and other biotech advances.
Key Takeaways
- Researchers analysed nearly 900 dogs across about 120 breeds and measured age-associated DNA chemical changes.
- Large dog breeds showed faster accumulation of epigenetic changes that coincide with increased transposable element activity.
- Independent teams released CRISPR-based cellular lineage recorders that map mammalian embryo cell divisions in unprecedented detail.
