The world’s top universities have a lot in common – renowned academics, rich histories, and a Cambridge postal code, The Christian Science Monitor reports. That according to a popular global ranking of universities put out this week by Quacquarelli Symonds (QS), a British-based higher education consulting firm, whose annual World University Rankings list is topped by three institutions that call a city of Cambridge home. Overall, the United States and United Kingdom dominate the leader board, but they’re increasingly being challenged in crucial science and technology fields by East Asia’s powerhouse universities, including the University of Tokyo, the National University of Singapore, and the University of Hong Kong. No Latin American or African universities cracked the global top 100 this year, but the University of Sao Paulo in Brazil (No. 139 in the world) placed among the top 50 schools in five specific subject areas. Meanwhile, Africa’s top institution remains the University of Cape Town in South Africa, which clocked in this year at No. 154.
