Is CRISPR gene editing doomed, even as gene therapy enters the clinic? -—Anyone watching the recent 60 Minutes segment on CRISPR would conclude that the gene editing technology is on the brink of pouring forth a cascade of cures. But a recent study reveals a mess of missing and moved chromosome parts in the wake of deploying the famed "molecular scissors."

How to make the gene-editing tool CRISPR work even better. Among the most significant scientific advances in recent years are the discovery and development of new ways to genetically modify living things using a fast and affordable technology called CRISPR. Now scientists at The University of Texas at Austin say they've identified an easy upgrade for the technology that would lead to more accurate gene editing with increased safety that could open the door for gene editing safe enough for use in humans.
