Scientists in South Africa are literally making rhino horns radioactive to fight poaching! They’re injecting harmless isotopes into the horns so customs agents can spot them with radiation detectors at airports and borders. The project’s called Rhisotope, and it’s already shown that even a tiny bit of radioactivity can trigger alarms—even inside a shipping container. The best part? It’s totally safe for the rhinos. Could this be the wild new way to save these endangered giants? #Science #RhinoConservation #AntiPoaching
