CRISPR is starting to become more and more of a reality as Harvard professor David Liu continues to work on it. Liu was the person who originally developed CRISPR first base editor which allowed for single letter changes in the genetic code. Liu has come up with two new features to CRISPR-Cas9.
The first is called cellular detective or CAMERA(CRISPR-mediated analog multievent recording apparatus systems). What this function does is it finds the genetic problem that is responsible for the disease someone is experiencing. Cas9 will record all the cell data and piece info together, which overall will provide more information about cancer, stem cells, aging, and overall disease.
The second finding is referred to as sharp scissors which is a CRISPR enzyme. Sharp scissors are way more precise and accurate than the old enzyme making is much safer. The scissors depend on specific DNA to find the region where it is supposed to cut or edit. CRISPR is progressing and as more research is being done could be used on humans in the future.
