You can spend a lot of time browsing through this site from the University of Wisconsin. The home page has a section on science in the news that delves into current topics that are covered exhaustively. In addition, there are hyperlinks to questions about weather, book reviews, great images, and archives of articles back to 1996, which are arranged by subject and by theme. There is also a section that correlates Why File stories with National Science Education Standards. The classroom activities include interactive games, lesson plans, and discussion questions. This is a treasure trove of current science topics.
