Chinese scientists have published three papers describing how they had edited human embryos. The step, which goes beyond previous experiments conducted a year ago in China, takes humanity one step closer to being able to fight back against hereditary diseases by simply repairing the genetic deformities that cause illnesses.

According to MIT Technology Review, which first reported the news on Wednesday, the experiment was only an exercise in science - the embryos were not allowed to develop for more than a few days and were not meant to be implanted into a womb.

Successfully undertaken by United States scientist Shoukhrat Mitalipov, based at Oregon Health and Science University, the use of CRISPR (clustered, regularly interspaced, short palindromic repeats), enabled scientists to edit and modify parts of DNA to prevent potential hereditary diseases. According to experts, the technique was much more precise than some types of gene therapy that can not ensure that desired changes will take place exactly where and as intended. However, with germline editing, concerns remain surrounding the idea of "designer babies" and eugenics.

It has recently been revealed that human embryos have been successfully "edited" through the use of a gene editing tool by leading U.S. scientists.

In May 2013, Dr Mitalipov was the first scientist in the world to demonstrate the successful use of somatic cell nuclear transfer, or SCNT, to produce human embryonic stem cells from an individual's skin cell. "While there will be time for the public to decide if they want to get rid of regulatory obstacles to these studies, I do not find them inherently unethical".
