The Buzz About Genetically Modified Mosquitoes

Researchers use a CRISPR-Cas9 strategy to expand a desired trait from 50 percent of mouse pups to about 72 percent.

United Nations members agree to some restrictions on the technology, but not a total suspension of its use.

No females were produced after eight generations, causing the population to collapse.

It’s the first demonstration of the technology in mammals.

In lab populations of genetically engineered mosquitoes, mutations arose that blocked the gene drive’s spread and restored female fertility.

A computer model estimates that gene-drive technology could wipe out populations of an invasive mammal on islands. 

Rare genetic variants could blunt efforts to destroy pest populations.
