The last male northern white rhinoceros died in 2014, meaning that the species is set to go extinct. But rather than watching the species die before their eyes, biologists have been hard at work trying to save the northern white rhino. They believe via artificial insemination, the abundant southern white rhino can help their northern cousins survive—despite being a different species. In a paper published this week, researchers successfully reported creating hybrid in-vitro embryos using eggs obtained from a southern white rhinoceros and preserved sperm from a northern white rhino. If implanted in a southern white rhino, the embryos could lead to a new generation of northern white rhinos.
