I SCIENCE has achieved 28 issues.  It is a topical, well-written magazine about issues and trends in the science world.  Sometimes, the issues are themed, e.g.: Issue 27 is subtitled “The Moral Issue”.  From their Homepage, one can link to Blogs, Features, Podcasts & Videos, Reviews, Magazine (issues) and Contacts.  It doesn’t appear to be searchable, but browsing can be fun and interesting.  Issue 28 (July 2014) on extremes or superlatives, includes articles about extremophiles, super evolutionary adaptations, the speed/physics of catamarans, human body extremes, ocean bottoms, the deep web and nanotechnology.
