This week on The Method Section, Tom takes a look at CRISPR. Gene editing via CRISPR and the Cas-9 protein was heralded as one of the biggest scientific acheivements of the last decade, but what exactly is it? How does one program a protein to precisely cut strands of DNA? The discussion of what CRISPR technology is being used for now and in the future is a rigourous one filled with all kinds of ethical bounderies and gray areas. Listen now to find out where they are drawing the line! Music by: Joakim Karud - https://soundcloud.com/joakimkarud.
