First test tube rhino embryos could bring extinct species back from dead

The northern white rhino is essentially extinct - just two females remain - but new research paves the way for its resurrection

The first rhino embryos have been created in a test tube and could help save the northern white rhino, which is essentially extinct.

There are just two northern white rhino (NWR) females left alive. The last male, called Sudan, died in March in Kenya, meaning the subspecies is doomed to die out unless the new IVF techniques bear fruit.
