I've listened to articles on the same subject from both Science News (SN) and Scientific American (SA)from Audio Books. My experience is that articles come out a month or two earlier on SA, and in greater depth than SN articles. On the other hand SN covers a greater breadth of subjects. If you've ever read a paper SA magazine you know how integral the pictures, illustrations and graphs are for conveying the full content of an article. A picture is worth a thousand words, and the audio version of SA doesn't acknowledge they even exist. The SN articles are at the right level of detail for the audio format.
