The gene-editing technology known as CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is transforming everything, from pharmaceutical research to agriculture to the process of making yogurt (really). It is a disruptive technology that allows people to edit genomes, changing the genetic code of life. In some cases, it's also raising complicated global questions about risk, regulation and even human values. So, should we be excited or afraid? Come discuss these questions and more with science writer Jennifer Kahn, who gave a 2016 TED talk on CRISPR.
