"The United States held steady in the just-published Academic Ranking of World Universities, or ARWU, dominating global higher education with 17 universities in the top 20 and 149 in the top 500 – one fewer than last year. Some institutions swapped places in the top 20 but they were all still there except for the University of Tokyo, which slipped a place to make way for the Swiss Federal Institute of Technology, ETH Zurich."
