Scientists working to save the northern white rhino from extinction have produced two more embryos of the world’s most endangered mammal, increasing the number of viable embryos produced so far to five. There are no known living males and neither of the two remaining northern white rhinos on Earth - a mother and her daughter living in Kenya - can carry a calf to term. Scientists hope to implant embryos made from the rhinos’ egg cells and frozen sperm from deceased males into surrogate mothers from a more abundant rhino species. The work of the BioRescue research team has been hampered by the coronavirus pandemic as international travel restrictions delayed some of its procedures.
