Chinese scientist returns to anxiety with a second pregnancy genetically created



Voice of America Report

Chinese researcher He Jiankui, criticized after his recent claims that he collaborated on the creation of two genetically edited twins, returned Wednesday to the scientific community to announce that there could be a second pregnancy.

He, an associate professor of 34 years old from a southern teacher in Shenzhen, revealed a possible new pregnancy in his first public comments on a controversial project at an international conference in Hong Kong.

DNA change before or at the time of conception is a highly controversial problem, since the changes may be inherited or may damage other genes. This practice is prohibited in some countries, including the United States, with the exception of laboratory tests.

Experts said that His work is unethical and unscientific.

I defended his work, claiming that he changed the DNA of two twins who were born earlier this month to try to make them immune to the AIDS virus.

“They need this protection because there is no vaccine,” he said amid criticism.

But the scientific community has condemned the experiment, and universities and government groups are investigating the situation.

The second possible pregnancy is at a very early stage, and it takes more time to check whether it will continue, he said.

The second possible pregnancy is at a very early stage, he told Jiankui on Wednesday, November 28, at a conference in Hong Kong.

Leading scientists say they are increasingly concerned about this issue.

The director of the conference he attended described the experiment as “irresponsible” and said that the scientific community had failed in its plan to self-regulate and avoid attempts to change DNA.

He claims, for example, that he chose HIV instead of a fatal congenital disease in order to check the genetic publication, and insisted that girls could benefit. But his colleagues did not seem satisfied.

"This is truly unacceptable progress," said Jennifer Dudna, a scientist at the University of California at Berkeley and one of the inventors of the tool for editing the CRISPR genes. He said she used.
