Conservationists in South Africa are trying something new to deter rhino poaching. They’re drilling holes into rhinos’ horns and inserting non-radioactive isotopes which will alert radiation detectors if and when someone tries to smuggle them across a border point. Since poachers won’t know which rhinos are carrying the isotopes, researchers are hoping it could make poaching a riskier business. Inside Edition Digital’s Mara Montalbano has more. #InsideEdition
