The genetic data that underpins CRISPR has a big diversity problem.

Medicine has entered a new era in which scientists have the tools to change human genetics directly, creating the potential to treat or even permanently cure diseases by editing a few strands of troublesome DNA. And CRISPR, the gene-editing...
