A sedated rhino is being prepared before a hole is drilled into its horn and isotopes carefully inserted, at a rhino orphanage in Mokopane, South Africa, Thursday, July 31, 2025.
MOKOPANE, South Africa (AP) — A South African university launched an anti-poaching campaign Thursday to inject the horns of rhinos with radioactive isotopes that it says are harmless for the animals but can be detected by customs agents.
Under the collaborative project involving the University of the Witwatersrand, nuclear energy officials and conservationists, five rhinos were injected in what the university hopes will be the start of a mass injection of the declining rhino population.
