Hatch and Release - Fighting Zika

In this new Scientist at Work video, learn how a line of genetically modified mosquitoes was engineered several years ago, and how scientists recently released them into the wild to help slow down the spread of Zika in Brazil. Male mosquitoes with a lethal gene are raised in the lab on tetracycline, an antidote that keeps them alive long enough to mature. Once released in the wild, they mate with non-GM females and pass on the lethality gene to the offspring who, without access to tetracycline, die before growing into adults.
