Scientists have successfully fertilized eggs taken from two female northern white rhinos, a year after the last remaining male died. The procedure has raised hopes about saving the highly endangered animals.
Sudan, the world's last male northern white rhinoceros, was euthanized last year after age-related health issues began to worsen.
The 45-year-old rhino shot to fame in 2017 when he was listed as "The Most Eligible Bachelor in the World" on the dating app Tinder, in a fundraising effort.
He left behind his daughter Najin and his granddaughter Fatu as the last remaining members of their species.
The team of scientists involved in trying to save the species is being led by the Leibniz Institute for Zoo and Wildlife Research in Berlin and is being funded by the German Ministry of Education and Research.
The ultimate goal is to create a herd of at least five northern white rhinos that could be released in their natural habitat in Africa, although that process could take decades.
Other species of rhino, including the southern white rhino and the black rhino, are frequently targeted by poachers who kill the animals for their horns to sell in illegal markets in Asia.
In the 1970s, Kenya was home to around 20,000 rhinos, but decades of poaching have reduced the number to an estimated 650.
