NAIROBI (Reuters) - One of the world's last two northern white rhinos, a mother and her daughter, is being retired from a breeding programme aimed at saving the species from extinction, scientists said on Thursday.

Najin, 32, is the mother of Fatu who is now the only donor left in the programme, which aims to implant artificially developed embryos into another more abundant species of rhino in Kenya.
