PubMed News Feeds (RSS)
PubMed makes it easier to stay current with some of its literature and bioinformatics databases by providing several news feeds in the RSS 2.0 format. These feeds, available at the NCBI website, describe the latest enhancements in the PubMed database, the PubMed Central full-text repository, new entries in the Unigene and Homologene databases, etc. There is also a brief FAQ page about PubMed RSS. If you would like to learn more about using RSS to stay current with research literature, there's a video tutorial (3 minutes, 19 seconds) about this topic.
