Researchers used an advanced genome-editing tool to study human development. They aimed to understand the role of a key gene that controls early stages of growth. The goal was to see if this technique could be used one day to treat diseases or enhance traits. However, they found some cells in the embryos were not edited, which may affect future uses of this technology. This discovery is part of ongoing debates about using genome-editing tools to create babies.
