They used a new technique called gene editing, one that allows for the precise placement of new DNA so that it has just the desired effects. And the particular gene editing technique they used, called CRISPR, causes the new trait to spread rapidly because it almost guarantees that the new gene will be passed along to new generations. “This opens up the real promise… [Read the rest of the story from our partners at NBC News](http://www.nbcnews.com/health/health-news/gene-engineered-mosquitoes-cant-spread-malaria-researchers-n468481?cid=par-time-tech%5F20151124) ## Transcript [ MUSIC ] 584, 000 people died from Malaria in 2013, most in Sub- Saharan Africa.
