A Chinese scientist has shaken the scientific world with the first genetically modified babies



A Chinese scientist, who claims to have created the world's first genetically modified babies, said on Wednesday that his actions were safe and ethical and proud of what was done. However, many other scientists are extremely skeptical, and forum organizers have described their actions as irresponsible.

"I'm especially proud of this case."Professor He Jiangui, in front of his colleagues at an international conference on gene modification in Hong Kong, said that the two twins offered an experiment to modify their DNA and thus could not be infected with the AIDS virus.

In his words, we now have a chance to protect another pregnancy with a genetically modified embryo.

The only thing he did apologize for was that he was using CRISPR genetic engineering to replace the embryos and then implanting them in the womb of a woman who gave birth to two twins this month.

His scientific achievement, he said in a statement so far, is not an independent confirmation, the BBC notes, but the news shook scientific society. Many academics denounced Jianguy, and some even described their idea as monsters. Scientists work diligently to avoid such embarrassment by using advanced technology to change human DNA.

This kind of research was banned in many countries of the world.

Hong Kong scientists, including first-class geneticists, think that He Jiangsu's behavior is not ethical. They point to the serious questions that have yet to be answered about the safety of embryos. Therefore, such research should be conducted in a transparent and controlled manner in order not to abuse the technology.

On Wednesday His presentation failed to calm down his colleagues.

Immediately after his presentation, David Baltimore, Nobel Prize winner, chairman of the Conference Organization Committee. He said the New York Times was irresponsible.

Or I don't think it's a transparent process, and I don't think it's a medical requirement, “says Dr. Baltimore.

Robin Lovell-Bege, professor of genetic and embryology at the Francs Crickeys Institute in London, asked Ha Jianguy why he needed such a great deal of confidentiality, especially because he was aware of the notion that the scientific community still did not exist. for actions.

The accusation has now violated the law. If you had asked the Chinese authorities, they would say you couldn't do it, Lovell-Bege said.

He said he was not familiar with the research project in Shenzhen, the University of the South of the University of Science and Technology, and that an investigation would be launched.

He confirmed that he knew the University was unfamiliar and that he financed the experiment with his own funds.

Boyunca Lulu ler and et Nana boyunca said that the newborn twins were lar normal and healthy “and wanted to follow their development for the next 18 years.

Jiangsu said eight pairs of HIV-positive fathers and HIV-negative mothers gave written consent for voluntary participation in the experiment. The professor then chose one of these couples.

He said that he had given his scientific work to a scientific journal to study and evaluate it, but that it did not say what the publication was.

The technology that CRISPR claims to use with genetic engineering is not new to the scientific world. It was first discovered in 2012. It works using "molecular scissors" to modify a very specific DNA fragment – cut or replace or change.

Genetic regulation can help protect against hereditary diseases by removing or replacing the problem code in embryos.

However, experts warn that interventions in the embryo genome may harm not only the individual but also future generations who inherit the same corrections.

Hundreds of Chinese scientists in social media Prof. They published a signed letter, which they categorically opposed to He's actions.

Professor Julian Sevourlescu, an ethics expert at Oxford University, has previously said to the BBC:: If this is true, this experiment is monster, and the genetic modification itself is experimental and still associated with mutational deviations. It can cause genetic problems, including the development of cancer at the beginning or later of life.

Or This experiment puts healthy children at risk of gene editing without real benefit, “he says.

Many countries, including the United Kingdom, have laws that prohibit the genetic modification of embryos in human growth.

Scientists can conduct in vitro fertilized fertilization on fertilized embryos and discard them immediately and not use them for infants.
