Turning Over DNA

Arrrgh, Matey. Keep ’em off the ship:

Pest experts in parts of Britain have noticed an increase in the number of rats who appear to be immune to poisons.

But researchers from the University of Huddersfield believe a new type of “super rat” with genetic mutations makes it resistant to commonly used poisons.
