SciAm is not peer reviewed to the best of my knowledge, hence the "even" modifier in my post. It's authors are, however, recognized experts in the fields about which they write. They write about the state of science (in their fields) for informed laypersons. Its editorials and columnists are, especially today, entirely politicized and all in the same direction.
