Created by dedicated staff members at the World Health Organization (WHO) Collaborating Center at the University of Pittsburgh, Supercourse is "a repository of lectures on global health and prevention designed to improve the teaching of prevention." The group's network of experts includes over 56,000 scientists in 174 countries who have produced well over 5,000 lectures in 31 languages. It's quite impressive, and first-time visitors may wish to click on the Lecture of the Week on the homepage. Visitors can also search the lectures, where they will find a range of topics from "Urbanization and spatial inequalities in health in Brazil and India" to "A Simple Model for Improving Global Health Education." Researchers and others can use the Publications area to find out where some of the work offered here has been published over the years. Visitors shouldn't miss the Special Lectures area. Here they can look over some of the Supercourse Golden Lectures, which include talks in Chinese, Arabic, Croatian, and Albanian.
