New gene-editing technique shows promise in negating bad mutations

We've all heard a lot about genetic modification this year, thanks in large part to one Chinese scientist taking it upon himself to edited the genes of human babies. His work was universally decried by fellow scientists and he got himself into some serious trouble because of it.
