Why is the scientific world abuzz about an unpublished paper? Because it could permanently change human DNA

Scientists around the world are anticipating the results of a Chinese study that would mark the first time DNA in a human embryo has been modified in a way that would carry into future generations. Although the embryos would be for study only, and not intended for implantation, the research would mark a significant milestone: the first time human DNA had been altered so substantially that it would change the “germ line” — the eggs or sperm of any child produced from the embryo.

Theoretically that could allow parents in the not-too-distant future to essentially clean their own eggs and sperm of undesired genes — such as ones known to cause cancer — and prevent those genes from being passed on to grandchildren and great-grandchildren.

How do people feel about this ethically?
