PubMed Also-Viewed: Quickly find related articles


You’ve seen it before on shopping web site: you load a page displaying an item you want and see a list of other items that people bought with the one you’re viewing.

PubMed is free, but finding the important articles on a topic can cost a lot of time. To help you keep on top of the literature – with a little help from your fellow PubMed users – we are introducing a new type of link called “Articles frequently viewed together”. For some PubMed abstracts, you may see this link in the “Related Information” section in the right column.

SmartBLAST: Faster BLASTp search results in a graphical view


BLAST (Basic Local Alignment Search Tool) is a popular tool for finding sequences in a given database that are similar to a query sequence. Traditionally, BLAST displays these results as a sorted list of matches between the query and each database sequence. While this display is useful for examining how each subject sequence matches the query, it treats all subject sequences the same, regardless of the quality of the sequence data or its annotation, and also does not allow easy comparisons between different subject sequences.

For example, the subject sequences may fall into multiple groups of similar sequences, or all of the subject sequences may be more similar to each other than to the query. A common way to obtain this information is to construct a multiple sequence alignment of the query and some or all of the subject sequences, but to this point, BLAST has not provided such alignments directly.

Enter SmartBLAST! SmartBLAST is a new and experimental NCBI tool that makes it easier to complete common sequence analysis tasks, such as finding a candidate protein name for a sequence, locating regions of high sequence conservation, or identifying regions covered by database sequences but missing from the query.

Introducing NCBI Labs


Welcome to NCBI Labs!

NCBI Labs is all about you. It’s a new NCBI initiative for creating innovative and relevant products by involving you, our user community, from the beginning.

NCBI Labs is about experimentation. It’s a place where you’ll find early versions of new tools, experimental content, and proposed features, as well as an opportunity to suggest ideas to us.

NCBI Labs is about learning. It’s a place where the focus is on figuring out what works, where failure is OK because it’s a learning experience, and where any idea is welcome that can improve our services for our users.

NCBI Labs is about conversation. It’s a place where we can share future plans with you, and you can tell us how we’re doing. It’s a place where we all can come together to create resources that will benefit the broader scientific community.

Join the conversation!
