THOMSON SCIENTIFIC NAMES “HOTTEST” RESEARCHERS OF 2004-2005

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

Philadelphia, PA USA-London UK — February 27, 2006 — 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.
