These two women have collaboratively arrived at a very accurate and repeatable method of genome editing which has huge ramifications for human health, longevity and the very nature of our species going forward. We are now at a point where the human genome can be edited like a piece of text in Microsoft word. Specific genes can be targeted and replaced, deleted or changed with crispr- Cas9 , reliably and repeatably. crispr-Cas9 can theoretically be used to reset the teleomeres of an individual to achieve indefinite lifespan. Who will win? who will lose? who wants to live forever?
