Editorial

SciAm has always fed the passion of our readers for information that isn’t provided elsewhere — the kind of information that is incredibly responsible and carries with it unparalleled authority and credibility. We immerse our readers in the R&D pipeline — across industries — to give them the best view of the technologies and breakthroughs that are shaping the world. That, of course, includes topics that are very much top-of-mind these days such as energy, the environment, security and healthcare.  

Every month the six feature articles include: Information Technology, Biotech, Physical Sciences, Life Sciences, and one or two articles on other subjects such as policy, healthcare, psychology and economics.
