This past July, Scientific American unveiled a bold new look for its flagship monthly magazine. In keeping with that theme of reinvention, we have now redesigned our web site. Visitors will still find the same cutting-edge daily news, in-depth features and fascinating columns and podcasts they've come to expect from The layout is sleeker, more user-friendly and takes better advantage of the web medium, however. And we've added some exciting new features, too.

We know from experience that a single story on a fascinating subject often isn't enough—you want to learn more. We also know that many readers come to our site in the course of researching a particular area of science. To that end, we have built topic pages that pull together our content on a given theme—global warming, for example. We have a few dozen of these topic pages so far, and we'll be adding to this list as we go.

Scientific American's audience has always been vocal—our inboxes are full of letters that prove it. But we can only pack so many of those correspondences into the monthly Letters to the Editors column. We also thought readers might enjoy discussing our stories—as well as their own ideas and experiences—with each other. With that in mind, we have built a community site where members can create profile pages, chat about the latest SciAm stories, produce their own blogs, share photos and videos, and more. We hope to see you there.
