Editing genes both excites and worries me. It's powerful, but we don't know what will happen in the wild. So I'm interested that researchers have found a new way to make mosquitoes resistant to malaria, using a technique called a 'gene drive'.
Resistant mosquitoes could stop malaria completely, but because resistance would be passed on to the whole mosquito population, any side effects would spread quickly too. Who knows what extra consequences there might be?
The researchers are aware of the risks so are learning more before they act.
