Episode Details

Scientists have just created the world’s first hypoallergenic beagles using gene editing — a breakthrough that could let allergy sufferers finally own dogs without sneezing or skin reactions. The technique disables the gene responsible for producing the main allergen in dog saliva and dander, and after years of research, two puppies named Bailey and Alfie were born and tested successfully on humans. For people like Matt Walker, who’s lived with allergies his whole life, it’s a dream realized — now he can play with a dog without suffering. But this isn’t ready for prime time yet: long-term health studies, affordability, and ethical questions about shelter adoption loom as the science moves forward.
