Scientists have successfully modified the DNA of a human embryo to erase a genetic and lethal heart condition. The experiment, published August 2 in the journal Nature, used a tool known as CRISPR, or Clustered Regularly Interspaced Short Palindromic Repeats, and was the first to successfully “correct” a gene mutation in human embryos. Reactions to this news range from excitement to horror. Soon we could have the technology to help parents who carry genes for genetic disorders to conceive children free of those traits. But should we?
