Last male northern white rhino dies
The last surviving male northern white rhino was put to sleep on Monday after age-related complications worsened significantly, reports the BBC. His death leaves only two females -- his daughter and granddaughter -- of the sub-species alive in the world. Hope for preserving the northern white rhino now lies in developing in-vitro fertilisation (IVF) techniques

Attempts to use Sudan to prolong the species with the two surviving female rhinos had failed, and an account was created for him on the dating app Tinder last year, not to find love, but to help fund the development of IVF for rhinos.Image source: Reuters
