In 2016, farmers planted the first crops edited with CRISPR–a precise gene-editing method that the USDA doesn’t regulate like traditional GMOs. Gene-edited plants could help cure food allergies and resist drought and disease (though a major study published this year found that GMO crops failed to live up to some similar promises).
In the lab, CRISPR also shows promise to help cure sickle cell disease and AIDS (more frivolously, other researchers want to use gene editing to paint new designs in animal fur). In China in October, a patient with lung cancer became the first person to ever be treated with CRISPR-edited cells. Cancer trials in the U.S. will begin in 2017.
And in a year when thousands of pregnant women around the world may have been infected with the Zika virus, researchers also tested new ways to wipe out mosquitoes with gene editing (unsurprisingly, many biologists question whether humans should be deliberately driving a species into extinction).
The gene-editing tool could create drought-resistant grain or allergy-free peanuts. Will a society on edge about genetically modified food embrace this newest innovation?
