Thomson Scientific Examines Biology's Hottest Institutions, Authors and Journals

    Survey Takes a Look at Who Had the Highest Impact in Molecular Biology
    and Genetics 2002-2006

    PHILADELPHIA and LONDON, Feb. 20 /CNW/ -- Thomson Scientific, part of The
Thomson Corporation (NYSE:   TOC; TSX: TOC) and leading provider of information
solutions to the worldwide research and business communities, today announced
the results of a study assessing high-impact research in molecular biology and
genetics.  In the January/February issue of Science Watch, Thomson Scientific
analyzes data from its Essential Science Indicators to identify molecular
biology and genetics papers that rank among the top one percent most cited in
the field for their respective years of publication between 2002 and 2006.
    From the resulting sample of 1,300 high-impact papers, Science Watch
highlighted the institutions, researchers, and journals most heavily
represented. Such analysis is typically found in Science Watch, which uses
unique citation data to provide rankings, interviews and reports on today's
most significant science.
    Among institutions, the top spot went to the Howard Hughes Medical
Institute (HHMI), which was the most-cited institution in the field with
nearly 38,000 citations to its 199 high-impact papers.  (HHMI also took top
honors in 2000 when Science Watch last surveyed this field.)  Harvard
University and Massachusetts Institute of Technology (MIT) rounded out the top
three with 31,725 and 24,868 citations, respectively.

    "When evaluating a research field, it's important to look at more than
total citations to an institution's work," said Christopher King, editor of
Science Watch.  "Measures like 'citation impact' give us other indicators of
research influence and significance as viewed by the scientific community.
These measures allow smaller institutions, which generally publish fewer
papers, to highlight their contributions to a field."
    According to the measure of citation impact (or average number of
citations per paper), the University of California, Santa Cruz produced the
highest score, averaging 414.5 cites per paper, even though UC Santa Cruz
authors contributed to a comparatively small quantity of 13 high-impact
reports during the five-year period. One of these reports, however--a landmark
2002 study on the mouse genome--has been cited more than 1,700 times and is
the most-cited paper in the survey.  The National Human Genome Research
Institute came in second place with 337.5 cites per paper followed closely by
Cold Spring Harbor Lab with 336.5.

    This study also ranked the top 25 molecular biology/genetics authors by
their number of high-impact papers.  Eric S. Lander, of MIT and Broad
Institute secured first place with his impressive 22 high-impact papers, which
garnered 9,710 citations, for an average of 441.4 citations per paper.  Coming
in second was David P. Bartel of HHMI, MIT and Whitehead Institute with 19
papers, 4,542 citations and 239.1 cites per paper.  C. David Allis of
Rockefeller University followed Bartel with 13 papers, 1,986 citations and
152.8 cites per paper.

    "For the study, we turned our attention to those institutions that
fielded at least ten high-impact reports over the five-year period," said
Christopher King, editor of Science Watch.  "We used this benchmark along with
a subset of reports collected from Essential Science Indicators' 'Highly Cited
Papers.' By doing so, we were able to compile nearly 1,300 papers with which
we identified high-impact authors and journals."
