Yes it’s true: Genetically engineered mosquitoes
Modifying the genes of mosquitoes can transform these pests into a weapon capable of fighting disease. Zika, dengue and chikungunya are all viral diseases spread by the yellow fever mosquito, Aedes aegypti. Because there are no cures for these viruses, health officials are eager to find new methods to slow their spread. Genetically engineered mosquitoes are being studied as a tool for this reason.
Scientists are modifying the genome of A. aegypti mosquitoes by inserting a gene into the insect that prevents its offspring from surviving to adulthood. This gene, tTAV (tetracycline repressible transactivator variant), makes a non-toxic protein that essentially ties up the machinery inside the insect’s cells, so that genes key to survival are not expressed and the insect dies.
