Mix around genetically modified twins


Is anything technically possible in science done one day? Rapid technological advances could blow up ethical barriers, as evidenced by the controversial announcement of the birth of genetically modified babies.

Is ethics being run behind the technique, always with delay time? This question, as ancient as science itself, was raised this week with the birth of genetically modified babies in the world.

Although some scientists doubt the veracity of their claims, says Chinese researcher He Yanqui Changed the DNA of two twins to make them resistant to the AIDS virus.

He says he used it A genome-editing technique called Crispr-Cas9, which has revolutionized genomic medicine since 2012.

This announcement caused great turmoil, and the world scientific community unanimously condemned the person he described as a sorcerer's intern.

"Good science does not create knowledge in the middle of a vacuum: the context and consequences are critical, and the consequences of this irresponsible act can be disastrous" , Said Dr. Sarah Chan of the University of Edinburgh.

However, the criticisms were not so much at the beginning of genetic change in humans, but also in the very conditions of experience.

First of all, the fact that it was carried out outside each frame, alone and very early.

In fact, the consequences of The use of Crispr-Cas9, especially the possibility that genetic changes, transmissible from generation to generation, has unpredictable effects that lead to the creation of "monsters".

Another major ethical breach was the purpose of the experiment: Protect babies against AIDS and not cure them of an illness that threatens their lives.

The scientific community fears that the transgression of these ethical principles is suspicious of a very promising research industry.

"Launching a technological flight forward, while burning essential ethical steps, could cause us to go back" Says Cathy Niacan, a biologist at the Francis Creek Institute in London.

Therefore, some international scientific bodies should consider that genome changes may be acceptable in the future, but under strict control.

It was an unimaginable idea only a few decades ago, which illustrates the difficulty of erecting barriers that can not be erased.

"You can not say: It's taboo, period, and we're not talking about it any more," says Ann Cambon-Thomsen, director of research at the National Center for Scientific Research (CNRS).

"An essential component that shapes our humanity is the ability to reflect on what our technical capabilities allow" Continues Cambon-Thomsen, a member of the European Ethics Group (EGE), which advises the European Commission.

Human cloning remains a red line. "This leaves the medical framework, and it is difficult to prove useful for cloning" According to Anne Cambon-Thomsen.

After the heat caused by He announced Jiankui, the Chinese government announced that it will open a criminal case can go to jail for violating ethical standards.
