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.

This machine found something scientists thought was impossible…
If you want to talk to Mico, go to this link: bit.ly/CleoAbram-Copilot
In the middle of the desert, miles from any city, are two HUGE concrete tubes. They’re part of a giant machine running the most precise experiment humans have ever built…
Each tube is 4 kilometers long, and inside there’s a big metal pipe. And at the end of each pipe, scientists place some of the smoooooothest mirrors ever made. And then they fire a powerful laser that gets split down each tube, bouncing it back and forth… building up more and more power… until… they bring those beams back together… to discover something that just 100 years ago scientists thought was impossible to find!
Finding it took hundreds of scientists and over a billion dollars. But what did we find?? And what’s the cutting edge we’re finding NOW that makes those scientists want to build… AN EVEN BIGGER ONE?
Let me show you…
