When Feng Zhang was in his early 30s, he used a set of genes found in bacteria called CRISPR to pioneer a new kind of gene editing tool in human cells. Today, the MIT biochemist is studying a different set of microbial genes called TIGR. And they may be the key to developing CRISPR’s successor. For this SciShow Field Trips video, we traveled to Zhang’s lab to learn about what may be the next generation of gene editing.
