Corals grown using IVF have spawned for the first time on Australia’s threatened Great Barrier Reef, raising hopes of saving the world’s largest living structure from global warming.

During the Great Barrier Reef’s late November spawning event, trillions of eggs and sperm erupted into the ocean in plumes of red, yellow and orange to reproduce — a
