We’re kicking off September with some new features on our popular Web site. In addition to the excellent editorial, breaking news and other can’t-miss features on the site, we’re rolling out a contest here on the Editor’s Blog: Monday Mind Teaser.

Now that the kids are back in school, why not do something to strengthen your own brain and test your knowledge? Every Monday in September, visit the blog for a new Monday Mind Teaser to solve. When you have the answer, leave a comment on the blog with the correct answer and a comment about it. The first five layers to correctly identify all four puzzles win a pocket radio player!
