Story summary

In Australia, the invasive South American cane toads, introduced in 1935, have exploded to over 200 million, threatening native reptiles. In a groundbreaking effort, researchers are employing CRISPR gene-editing to engineer cannibalistic tadpoles that feast on the toads' eggs. Biologist Rick Shine sheds light on this creative strategy to combat the ecological crisis.
