Scientists in California, US, are using AI-powered drones to spot great white sharks and warn beachgoers when the predators are nearby. The SharkEye programme, developed by researchers at UC Santa Barbara, uses drone footage and artificial intelligence to detect sharks off the California coast and share real-time alerts with local officials and beach communities. Researchers say unusually warm ocean temperatures have led to higher-than-average shark numbers this summer, with a public app now being tested to help swimmers and surfers check conditions before entering the water.
