Which universities are declining for revolutionary science?

The American West is rising, Harvard is falling:

Nobel laureates nations and research institutions
were measured between 1947-2006 in 20 year segments.  The minimum
threshold for inclusion was 3 Nobel prizes.  Credit was allocated to
each laureate’s institution and nation of residence at the time of
award.  Over 60 years, the USA has 19 institutions which won three-plus
Nobel prizes in 20 years, the UK has 4, France has 2 and Sweden and
USSR 1 each.  Four US institutions won 3 or more prizes in all 20 year
segments: Harvard, Stanford, Berkeley and CalTech.  The most successful
institution in the past 20 years was MIT, with 11 prizes followed by
Stanford (9), Columbia and Chicago (7).   But the Western United States
has recently become the world dominant region for revolutionary
science, generating a new generation of elite public universities:
University of Colorado at Boulder; University of Washington at Seattle;
and the University of California institutions of Santa Barbara, Irvine,
UCSF, and UCLA; also the Fred Hutchinson CRC in Seattle.  Since 1986 the
USA has 16 institutions which have won 3 plus prizes, but elsewhere in
the world only the College de France has achieved this.  In UK’s
Cambridge University, Cambridge MRC unit, Oxford and Imperial College
have declined from 17 prizes in 1967-86 to only 3 since then.  Harvard
has also declined as a revolutionary science university from being the
top Nobel-prize-winning institution for 40 years, to currently joint
sixth position. 
Although Nobel science prizes are sporadically won
by numerous nations and institutions, it seems that long term national
strength in revolutionary science is mainly a result of sustaining and
newly-generating multi-Nobel-winning research centres.  At present these
elite institutions are found almost exclusively in the USA.  The USA is
apparently the only nation with a scientific research system that
nurtures revolutionary science on a large scale.
