FEATURED ANALYSIS, Jan./Feb. 2008

Sequencing Biology’s Hottest, 2002-06
by Christopher King

To assess high-impact research in molecular biology & genetics over the last five years, ScienceWatch.com turned to an elite selection of papers: those ranking among the top 1% most cited in the field for their respective years of publication, among papers published and cited between 2002 and 2006. This benchmark, applied to a special five-year subset of reports collected in the "Highly Cited Papers" area of Thomson Scientific’s Essential Science IndicatorsSM database, produced a file of some 1,300 papers published in Thomson-indexed journals of molecular biology & genetics.

(The analysis included pertinent papers published in the multidisciplinary journals Nature, Science, and PNAS.)

From this population of high-impact reports, ScienceWatch.com identified the institutions, authors, and journals most heavily represented.

#Table 1 (below) features institutions that fielded at least 10 high-impact reports over the five-year period. In the left-hand column, institutions are ranked by total citations, while the right column ranks institutions by impact, or cites per paper. Listings in table 2 (below) specify individual researchers who each contributed to at least eight high-impact reports, along with journals (table to the right) that published 20 or more such papers.

As was the case when Science Watch last surveyed high-impact research in this field (11[5]: 1-2, September-October 2000), the Howard Hughes Medical Institute garnered the highest citation total of any institution, with nearly 38,000 collective cites. HHMI-affiliated authors, in fact, contributed to 199 high-impact reports, a total approached only by Harvard’s 165 papers.

In tallying citations to papers by Hughes investigators, Science Watch credited both HHMI and the investigators’  home-base institutions, since Hughes investigators usually list both affiliations in their papers, and since such papers often include the contributions of non-Hughes-supported coauthors at each institution.)

In the cites-per-paper column, no institution surpassed the University of California, Santa Cruz, even though UCSC fielded only 13 high-impact molecular biology & genetics reports during the five-year period. One of these, however, was the most-cited paper in the survey, a 2002 Nature report on the mouse genome (Mouse Genome Sequencing Consortium, Nature 420[6915]: 520-62, 2002). This paper has now been cited more than 1,700 times.

Among the 200-plus coauthors on this blockbuster mouse-genome report was MIT’s Eric S. Lander, who topped the researcher list with 22 high-impact reports. (The list is ranked by number of high-impact papers, with the subsequent order determined by total citations). Lander also contributed to highly cited genomic studies centered on yeast, the chimpanzee, and the domestic dog.End
