The Australian Broadcasting Company recently aired Life Changing Science, "a four-part series examining innovations that have transformed our lives." This companion Web site offers fantastic interactive features to go along with each of the four radio broadcasts. Three of the four interactive "labs" focused on the life sciences. They include Virtual Open Heart Surgery, in which users can conduct a highly simplified version of the real procedure; In Vitro Fertilization, which offers an excellent overview of the IVF cycle; and Food Preservation, in which users can test how well they know their kitchen microbes. These interactive features are truly cool, although American readers must contend with the metric units used in Food Preservation. The site also includes audio of the original radio programs, which aired in June 2003.
