Manuel Serrano, ICREA researcher and head of the Cell Plasticity and Disease Group at IRB Barcelona, has been interviewed on Radio 4´s programme De boca a orella. The interview was about ways to measure biological age. The scientist says that one of the techniques receiving most attention is the epigenetic clock. He goes on to explain that this is a “clock” present in our blood and that, combined with the study of other factors such as telomeres (the structures that form at the ends of chromosomes), it serves to measure biological age. He goes on to say, ““Chromosomes are the structures in which lineal DNA is found. We have 23 chromosomes and their ends hold a repeated structure. It is known that these repetitions get shorter over time”.
