Cell, the flagship journal of Cell Press, an imprint of STM publisher Elsevier, has been ranked cell biology's top research journal, according to the 2007 Journal Citation Reports published by ThomsonReuters.
In the report, released earlier this month, the journal's impact factor increased to 29.9 from 29.2 last year, placing Cell higher than competing research journals Science and Nature in this ThomsonReuters ranking. The impact factor is a measure of the frequency with which the average article in a journal has been cited in a particular year. The impact factor helps to evaluate a journal's relative importance, especially when compared with others in the same field.
The 2007 Journal Citation Reports show that 43 Elsevier journals ranked number one in their respective categories, including Cell Press journals Trends in Ecology & Evolution (#1 in Evolutionary Biology); and Trends in Cognitive Science (#1 in Experimental Psychology). In addition, Cell Press titles Cell Metabolism (17.2) and Immunity (19.3) both greatly increased their impact factor from the previous year.
