Can we live longer? And does the answer lie in Physics?

Posted by in categories: biotech/medical, life extension

Physics is not the first scientific discipline that springs to mind at the mention of DNA, but a group of scientists, including John van Noort from the Leiden Institute of Physics (LION) have discovered a new structure of telomeric DNA.

Longevity. Technology: In every cell of our bodies are chromosomes that carry genes that determine our characteristics. At the ends of these chromosomes are telomeres, which protect the genes from damage. Telomeres are rather like aglets, the plastic tips at the end of a shoelace – they protect the DNA from damage and fraying. However, every time a cell divides, the telomeres become shorter, until eventually the Hayflick Limit is reached, the cell can no longer divide and apoptosis – programmed cell death – occurs.

This means that telomeres are sometimes seen as the key to living longer, and the researchers behind this new discovery hope it will help us to better understand aging and age-related diseases.
