Genetics: the brain of the first CRISPR children can work much better than that of ordinary people

The CCR5 gene is associated with cognitive abilities and memory. In 2016, a group of scientists led by Silva

conducted the removal of the CCR5 gene from the mouse brain, whichled to a significant improvement in their memory. At the same time, it is not yet clear how editing the gene will affect the cognitive abilities of people, since such experiments have never been performed, but it could not but affect the functioning of their brain.

According to Silva, as soon as he found out aboutHe's experiments, I immediately thought that the real reason for conducting the experiments was precisely in enhancing cognitive abilities, and not in HIV resistance. At the same time, journalists note that there is no confirmation of Silva’s words yet.

On January 22, Chinese authorities officially confirmedthe birth of the world's first children of edited embryos - Lulu and Nana. The birth of the world's first children with edited genes became known at the end of November, but the scientific community was skeptical about the statement made by geneticist Jiankuya He due to the lack of scientific work and research.

During the investigation, the Chinese authorities came toconcluded that Jiankui He conducted all experiments on the editing of embryo genes, trying to instill in them resistance to HIV, independently - without warning anyone about his experiments. The ministry’s report noted that He “intentionally avoided the attention of the authorities”, but did not explain what kind of supervision he was talking about.

"High-tech" understood in detail why almost all countries forbid experiments with editing genes in humans, as well as how the He experiment influenced all of world science.
