After discussing the second genetically modified babies, the global debate



November 26, 2018 – 7:44 PM
China says that human beings can change embryos in fertility treatments, of which twins are born. But it is very much in the scientific community.

A Chinese researcher created the genetically-edited babies for the first time, a twin-month, DNA-maker, has changed with a powerful new tool capable of rewriting the original lifestyle project.
If it is true, a great leap to science would be with deep ethical implications.
A United States scientist was involved in the genetic work of editing in China, which is why it is forbidden in the United States that DNA changes can occur to future generations and other genes are damaged.
Many scientists believe that there is a risk of too much probation and that the Chinese report is similar to that experienced by humans.

The future of HIV infection is endurance

The researcher, He Jiankui, in Shenzhen, said fertility had seven pairs of fertility treatments and had now a pregnancy. He said that his goal was not to cure or prevent hereditary illness, but rather to provide a feature that affects few people: the ability to have an HIV infection in the future, AIDS-infected virus.
He recalled that parents had to identify or interview, and did not reveal where they lived or where they worked.

He still does not confirm by science

No one has confirmed his or her assertion independently, nor published in a newspaper so that other experts can study it. He worked in Hong Kong on Monday, one of the organizers of the international conference on genetic editing on Tuesday and interviews of Elkarrizketa Elkarrizketak exclusively.
"I feel a solid reason not only for doing something for the first time, but also for setting an example," said AP. & # 39; & # 39; Society will decide what to do & # 39; & # 39; forbidding or forbidding the next scientific advances.

More than 120 scientists condemned Jiankui's jealousy on the birth of two children genetically modified to prevent HIV hiring, in an open letter that they experience in human beings, which leads to serious "illness" in an open letter.
The text was signed by scientists from different institutions, including Tsinghua, Beijing and Fudan universities and the Chinese Academy of Sciences.
"These irreversible transformations of material genetic material, which are not highly scientific, will necessarily confuse in the human genetic group," says the letters published by the DPA.
Researchers have said, "it is possible that healthy babies are healthy for the whole time, but the human potential and the potential risks are not unattainable."
Experimentation is a tough blow to the "global reputation of Chinese science" and asked the inspection authorities to act as soon as possible and to carry out a case study.
"The Pandora box has been opened and we may have to close the damages before being recoverable," they warned.

However, Harvard's renowned genetist, George Harvard, defended HIV's genetic editing, which he defined as "an increasingly important threat to public health."
"I think it is justifiable," he said.
In recent years, scientists have found relatively easy ways to edit genes, the branches of DNA that govern the body. The tool called CRISPR-cas9, DNA operations, provides a gene that is necessary or causes problems.

Jennifer Doudna

One of the anti-CRISPR-Cas9 editing techniques, American Jennifer Doudna, criticized the ad.
"If this is proven, this work breaks out from the transparency and transparency of the application of the CRISPR-Cas9 globalization community," said Doudna, Professor of Molecular and Cell Biology at the University of California, Berkeley.

Doudna said the research was not yet published or peer-reviewed by the scientific community.
The researcher participates in the Human Genome Summit of Hong Kong, and wants to take part in it.
If the scientific study confirms this work, "confirms the urgent necessity of using the genetic edition of human embryos, which does not cover clear medical skills and a therapeutic approach that is not possible," he said.
The CRISPR-Cas9 mechanism has been known for almost three decades, and in 2003, the Spanish microbiologist Francisco Martínez Mojica discovered the microorganisms used to defend itself by the microorganisms, cutting the genetic material of the viruses and incorporating the material into their own DNA.
Mojica discovery Doudna and Emmanuelle Charpentier were the founders of the French researcher a few years later, to artificially reproduce the system and propose it in 2012, it could be used to modify the genome, as well as for humans.
