Genome aficionados rely on the well-known BLAST search to find matches for a particular DNA sequence in gene databases. A site called eTBLAST from the University of Texas Southwestern Medical Center in Dallas lets you use the same idea to scan MEDLINE for germane articles. Enter a sentence or paragraph—say, from your latest paper—and you can search for abstracts with similar language. You can fine-tune the search by giving more weight to particular words. The results, delivered by e-mail, can take several minutes to arrive.
