Institutions in the United States dominate a new ranking of the world’s top 50 institutions.

US institutions occupy 33 of the top 50 positions, with Harvard University in first place and Stanford University, MIT, NIH, Yale University, California Institute of Technology and Columbia University also in the top ten. Six of the campuses of the University of California feature in the top 50, and if all ten were aggregated together the University of California system would be ranked number one.
