two binoculars are born genetically modified

In China, these researchers sign a first, which is not unanimous throughout the world.

They managed to genetically alter the bodies of two little girls, two twins, when they were still just cells.

Scientists detail their operation, during an in vitro fertilization.

The father of the girls suffers from HIVand he wanted to make sure that his girls would not develop the disease.

To do this, scientists would have used molecular scissors in order to modify the CCR5 gene, by introducing a synthetic protein.

In total, the operation would have been carried out on the embryos of seven pairs, but only these two embryos would have resulted in a birth.

However, this operation has not yet been approved by specialists, who question the researchers' version, and ask for more checks.

China has also decided to launch an investigation into the design of two binoculars that are already known as "GMO babies".

The two girls, Lulu and Nana, are in good health today.
