DNA from the human embryo has been modified by a Swedish researcher

Although human embryo gene alteration in a series of debates started last year, a Swedish researcher conducted intervention for the first time in history.

For the first time, Lanner Friedrike began to alter gene in healthy human embryo. Lanner hope to find new treatments for infertility and abortion using gene modification technology CRISPR-Cas9. It will turn off genes in the embryo to see what role each plays in early development.

Many people believe that modifying the gene will lead to the design of children by some parents' wishes. It also could lead to hereditary diseases us. Lanner said such basic research seeking to prevent situations of this kind.
