Ever since the early days of the Internet, various educational organizations and foundations have sought to use the Web to disseminate important pedagogical tools to fellow educators and interested parties. This very fine site sponsored by the Baylor College of Medicine and Texas A&M University does exactly that for the field of biology with great aplomb. First-time visitors will want to start by perusing the homepage, which includes links to "Hot Topics" in biology (such as flu prevention), a "Biology News" section (which digests important news from the field), and a selection of recent additions to the site. Educators will also want to take a look through the slide sets offered here, in the PowerPoint format, which include topics such as human body systems, ecosystems, and Mendelian genetics. Additionally, the site also features a number of streaming video presentations for classroom use on a wide range of biological topics.
