    Mushrooms won't be the only non-browning produce on store shelves for long. Thanks to genetic modification, we'll soon see Golden Delicious apples that don't oxidize for three weeks after being cut, bruised or bitten into. They'll be sold in packages of slices and will go on sale in the Midwest in February and March. According to Arctic, the company responsible for the fruit, this feat was achieved by "silencing" polyphenol oxidase (PPO) expression.
