An interesting new genetic modification to apples will make them resistant to turning brown, but they won't be available to consumers for a few years. On Friday, the U.S. government gave the green light to plant the gene-altered "Arctic Apples," which were developed by a Canadian company called Okanagan Specialty Fruits, according to The New York Times. They're "resistant to turning brown when sliced or bruised," the Times reported. The apples (Granny Smith and Golden Delicious, in case you're wondering) are engineered to suppress the enzyme that causes the browning, which many find unappetizing. (Although, a little lemon juice also does the trick.) If you're thinking, that sounds awesome, and wondering how this could possibly be controversial, here's our primer to everything you need to know about GMOs. This doesn't mean you can run to the grocery store and start stocking up. Trees have to be planted and then bear fruit, so it will be a few years before the apples hit the market, the Times pointed out.
