The time-consuming step in running a PubMed search of biomedical papers is often winnowing useful results from the chaff of extraneous hits. Spare yourself some frustration by trying out this free search engine, which automatically groups results by topic. For example, entering “MRI,” the focus of this year's Nobel Prize in physiology or medicine, tucks the hits into folders such as “bone marrow,” “motor cortex,” and “deep brain stimulation.” The tool comes from Pittsburgh-based company Vivisimo, which sells clustering programs but provides several free demos that use the same procedure to organize search results for FirstGov, the trove of U.S. government documents, as well as the Web.
