Swedish Scientist Begins Editing Human DNA in Healthy Embryos

A scientist from Sweden is the first researcher to ever edit human DNA in healthy embryos. Using CRISPR, Fredrik Lanner is modifying genes to figure out what they do, eventually hoping to discover more about infertility, miscarriages, and embryonic stem cells.

Whether creating GM crops or making animals disease-resistant, gene-editing has always faced harsh criticism. One fear is how altering human DNA in embryos could recklessly create a fatal genetic disease that would exist for generations.
