Scientists behind Dolly the sheep want to edit squirrel DNA to get rid of greys and protect reds UK

Daily Mail - Science & tech 

The scientists who cloned Dolly the sheep are now targeting grey squirrels in a bid to rid Britain of them altogether. Researchers at the Roslin Institute want to use DNA modification to make all female grey squirrels infertile. They are looking at creating a'gene drive' for male greys that would spread to females when they mate. Experts claim this would eradicate Britain's grey squirrel population completely in the most humane way possible. They want to decrease the number of greys in a bid to protect the few-remaining red squirrels left across the British Isles.
