Does anyone know of an issue of Scientific American Magazine that is mostly biology?
I looked through the synopses of the Scientific American magazines from 2003-2008 and I’m noticing a pattern: they all have a combination of sciences represented, usually biology and some geology/computing thrown in. No pure biology. However, you can check out sample contents (covers and the beginnings of the feature articles) of any Scientific American issue from 2001-2008 on their website. I’d encourage you to check it out and see if you can find one that fits your needs best.
