Popular Science Magazine using Drupal

From the PopSci website: 
"Popular Science has been a leading source of science and technology news since its inception way back in 1872. PopSci.com first came online in 1999, and in 2008 we launched our biggest redesign yet: a new site built in Drupal that’s easy to navigate and chock-full of exciting daily content.
The new PopSci.com is also highly customizable, so finding the content you're interested in is a breeze. The whole site is organized by keywords, so for instance, if you click the "robot" tag, you'll see only articles about robots. You can also search in the traditional way, or use our channel buttons to instantly sort content by category. And the latest stories about the topics that interest you most can be sent right to your newsreader with our custom RSS feeds.
With up-to-the-minute tech news, insightful commentary on the new innovations, and even scientific takes on the hottest Hollywood stories, we aim to be your first stop for what's new and what's next.
