Get ready, Brazil. The 'good mosquitoes' are coming

The thought of all these mosquitoes might make one's skin crawl. But Cabral thinks of them as her babies, and she says these insects deserve more praise than loathing. That's because they've been engineered to shut down the transmission of the very diseases they usually carry and spread.

Cabral has every confidence in these mosquitoes. "They can help us," she says.
