Finding all the bad apples

The USDA is working on a machine that can pick out bad apples without actually having to bite into them. It works by beaming the apples with lasers and then using artificial neural network software that can tell from how much light is bounced back the sugar content and firmness of each apple. (We were almost going to write "How do you like them apples?" for the title to this post, but then we thought better of it.)
