Barcelona fights mosquito-borne illness with parasites
Barcelona is conducting a large-scale experiment to reduce mosquito-borne diseases by releasing male mosquitoes infected with the wolbachia parasite. This method causes sterility in the population, offering a non-gene-editing alternative to combat illnesses like dengue as climate change expands insect habitats.
