CHORZOW, Poland (AP) — Only two northern white rhinos exist in the world: both are female and neither can bear calves. But scientists have not given up hope of saving the species from extinction.

They succeeded last year in creating hybrid embryos using frozen northern white rhino sperm and eggs from a southern white rhino, a closely related sub-species.

Now they are working on how to implant the embryos into a surrogate mother to bring them to term, and once they've mastered that, they can create purebred northern white rhino embryos that would be carried by a southern white.

As part of that work, on Wednesday, they are harvesting egg cells from southern white rhinos in zoos across Europe.
