Can Scientists Tell Your Age From a Blood Sample? (The Science of Epigenetic Clocks)

Can scientists really estimate your age from a simple blood sample? Surprisingly, the answer is yes.. but not for the reason you might think. In this video, we explore the fascinating science of epigenetic clocks and DNA methylation, and how tiny chemical marks on our DNA can reveal not only our chronological age, but also provide insights into our biological aging. You'll learn: - What DNA methylation is - Why different tissues have different DNA methylation patterns - How Steve Horvath developed the first multi-tissue epigenetic clock - How Morgan Levine's DNAm PhenoAge advanced the field by measuring biological aging - Why modern epigenetic clocks are transforming aging research Whether you're interested in genetics, epigenetics, longevity, aging research, or simply curious about how our bodies change over time, this video will help you understand one of the most exciting developments in modern biology. 📚 Key scientific papers discussed • Horvath S.
