A brief history of failed and successful attempts to convey scientific information in the same medium that brings you reality shows and prescription drug ads. Robert Bazell is NBC News' Chief Science and Health Correspondent. His reports appear on "NBC Nightly News, with Brian Williams" "Today" and "Dateline NBC." During his career with NBC News, which has spanned more than three decades, Bazell has reported on a wide range of subjects in the areas of science, technology and medicine throughout the United States and around the world. Bazell has received hundreds of awards for his reports, including four Emmys, the Alfred I. DuPont Columbia Award, the Edward R. Murrow Award and a Gracie Award. He has also received a George Foster Peabody Award, for which he was recognized for exemplifying "the best reporting on science and medicine. From transmission of the AIDS virus to innovations in cancer treatment, from the perceived dangers of cellular phones to alternative modes of health care, Mr. Bazell brings intelligence, understanding and reportorial excellence to the task. Robert Bazell is an outstanding television reporter who recognizes when to speak, when to listen and when to tell."
