Scientists Implant Radioactive Material Into Horn of Living Rhinoceros to Poison Anyone Who Consumes It

Warning Horn In an effort to make them useless to poachers, researchers are implanting radioactive isotopes into the horns of rhinos in South Africa. The unusual material would “render the horn useless… essentially poisonous for human consumption,” James Larkin, professor and dean of science at the University of the Witwatersrand in Johannesburg, told Agence France-Presse.

Space radiation can damage satellites − my team discovered that a next-generation material could self-heal when exposed to cosmic rays

The space environment is harsh and full of extreme radiation. Scientists designing spacecraft and satellites need materials that can withstand these conditions. In a paper published in January 2024, my team of materials researchers demonstrated that a next-generation semiconductor material called metal-halide perovskite can actually recover and heal itself from radiation damage. Metal-halide perovskites are […]
