Japanese researcher tops the list with most `Hot Papers’;
U.S. makes strong showing accounting for half of the top researchers

Authoring or co-authoring 11 "Hot Papers" on immune-system function, Osaka
University’s Shizuo Akira surpasses fellow scientists to earn the title of the
2004-2005 "Hottest Researcher." This, according to the March/April issue of
Science Watch - the bimonthly newsletter published by Thomson Scientific, a
business unit of The Thomson Corporation.

Marc A. Pfeffer of Harvard University led U.S.-based researchers (tied for
second overall) with eight Hot Papers in the field of Clinical Medicine.
Another Japanese researcher, Norio Tamura of Niigata University, tied Pfeffer
for second.

"Our annual roundup of the hottest research celebrates those scientists
making a significant impact," said Christopher King, editor of Science Watch.
"Having authored multiple Hot Papers is an achievement of the highest level, as
it truly demonstrates their impact on modern scientific thought."

The Thomson Scientific Hot Papers database identifies a published work as a
Hot Paper if it has achieved a rate of citations in scientific journals that is
markedly higher than papers of comparable type and age. The researchers named
in Science Watch published the most Hot Papers in the latest two-year period
indexed by Thomson Scientific.
