China’s CRISPR twins might have had their brains inadvertently enhanced
New research suggests that a controversial gene-editing experiment to make children resistant to HIV may also have enhanced their ability to learn and form memories.
The brains of two genetically edited girls born in China last year may have been changed in ways that enhance cognition and memory, scientists say.
The twins, called Lulu and Nana, reportedly had their genes modified before birth by a Chinese scientific team using the new editing tool CRISPR. The goal was to make the girls immune to infection by HIV, the virus that causes AIDS.
