Aging is the main risk factor for many diseases in the world today, from cardiovascular diseases to cancer. Inspired by this problem, Hannah was fascinated to dive deeper into whether we can reverse aging using a novel genetic engineering tool called CRISPR-Cas. Using this tool, Hannah was able to double the lifespan of fruit flies by editing only two genes. This is one among thousands of experiments around the world where we can successfully reverse aging in small animals. Our future is bright, and will be centered around making this effort more scalable to eventually prolong human life.
