The team used CRISPR on human embryos in a bid to render them resistant to HIV infection. But instead, they generated different mutations, about which we know nothing. SHUTTERSTOCK

China’s failed gene-edited baby experiment proves we’re not ready for human embryo modification

A number of things may have gone wrong when researchers edited Chinese twins Lulu and Nana's genome. Either way, the failed experiment is a cautionary tale for us all.
Scientists discovered some bacteria can cut the DNA of invading viruses as a defence mechanism. They realised they could use this to cut human DNA.

What is CRISPR gene editing, and how does it work?

CRISPR harnesses the natural defence mechanisms of some bacteria to cut human DNA strands. Then the DNA strand either heals itself or we inject new DNA to mend the gap. This is gene editing.
