NCBI will present the first iteration of NCBI NOW, a free online experience aimed at those new to next generation sequencing (NGS) analysis, from October 13-23. Enrollment in this course is limited to the first 1,000 participants who sign up through the ORAU Portal. Since enrollment is on a first-come, first-served basis, please only sign up for this educational opportunity if you will be able to participate fully. Learners will watch 6-7 videos (average video duration: 45-60 minutes) online during the first seven days of the course. These videos will cover the basics of NGS data, preprocessing, quality control and alignment strategies for both DNA-Seq and RNA-Seq, as well as a brief discussion of downstream analysis. Additionally, there will be demonstrations about leveraging BLAST tools for NGS analysis.
Next, participants will apply a selection of RNA-Seq alignment algorithms over three days (1-2 hours per day), mapping RNA-Seq data to GRCh38 chromosome 20. Finally, participants will compare the results of these mappers for specific genes. Throughout the course, participants will be able to post questions at Biostars; experts from NCBI and elsewhere will be available online to answer questions. Learners will emerge from the course equipped to map their own RNA-Seq or DNA-Seq data to the human genome, understand the options for downstream analysis, and use their understanding of the basic steps of data processing to interact more effectively with bioinformatician collaborators.
The NLM exhibit booth at the 2015 Annual Meeting of the Medical Library Association in Austin, TX, featured theater presentations to bring users up-to-date on several NLM products and services. The presentation recordings are captioned and accessible from the NLM Distance Education Program Resources page. The presentations include:
Note: To listen to the voice recordings and view the captions you may need the latest version of Flash® Player (download for free from the Adobe Web site). To maximize the presentation, use the Full Screen button. For more information, go to the NLM Technical Bulletin page.
The NCBI homepage has six new buttons on it: Submit, Download, Learn, Develop, Analyze, and Research. Each of these leads to an action page devoted to a particular set of services. These action pages allow easy access to the pages and resources you need to complete tasks. For instance, you can: Find information about the Entrez API; Find an upcoming NCBI webinar, Find an NCBI tool that designs PCR primers, and much more! On the new action pages, you’ll also see six categories in the header: Literature, Health, Genomes, Genes, Proteins, and Chemicals. These category pages highlight useful databases, tools and resources for each of the topics all in one place.
Also included is a blue Feedback button on the left side of the Download, Learn, Develop, and Analyze pages so that you can send comments to NCBI. More information about the new homepage will be released on NCBI News and to the blog, NCBI Insights.
The 22nd annual edition of the Nucleic Acids Research Database Issue features nine free full-text papers from NCBI staff that present recent updates to the databases, including GenBank, Gene, and RefSeq. These papers describe the state of NCBI databases as well as future plans to improve their use, from new reference resources created to improve the usability of viral sequence data to in-house curation efforts in the Conserved Domain Database, and much more. The articles are all available from PubMed.
SciENcv enhancements will include the new NIH biographical sketch format as a choice for creating SciENcv profiles. SciENcv will continue to support the current NIH biographical sketch format; however, NIH encourages researchers to use the new format with their grant submissions. Researchers will be required to employ the new NIH biographical sketch starting May 25, 2015. Users will be able to utilize their existing Science Experts Network Curriculum Vitae (SciENcv) profiles to create profiles in the new NIH biographical sketch format, as well as be able to select the new NIH biographical sketch format when creating profiles manually or through a data feed from an external source. The Personal Statement section of the NIH biographical sketch has been updated to include an option to list up to four peer-reviewed citations. A new section, Contribution to Science, replaces the former section Selected Peer-Reviewed Publications, and it aims to give researchers a place where they can describe five of their most significant contributions to science.
SciENcv users will also soon be able to create profiles in the National Science Foundation (NSF) biographical sketch format. This newly added format will be available to download in PDF, MS Word or XML, and users will be able to share their SciENcv NSF profiles through a public URL. In addition, by linking your NSF account to an NCBI account, you will be able to populate SciENcv profiles with information stored in your NSF account. The NSF biographical sketch is the official format used for grant submissions to the NSF and consists of five sections: Professional Preparation, Appointments, Products, Synergistic Activities, and Collaborators & Other Affiliations.

The HIV-1, human interaction database has been updated and is now on an improved page. The improved interface includes help documentation and supports structured queries against Gene, as well as browsing, filtering and downloading the protein and replication interaction data sets. The most recent data release (June 2014) includes 12,785 HIV-1, human protein-protein interactions for 3,142 human genes and 1,316 replication interactions for 1,250 human genes. The HIV-1, human interactions project, collates published reports of two types of interactions – HIV-1, human protein interactions, and human gene knock-downs that affect virus replication which are reported as “replication interactions.”
Health science librarians in the United States are invited to participate in the next offering of the bioinformatics training course, A Librarian’s Guide to NCBI, sponsored by the National Library of Medicine (NLM), the National Center for Biotechnology Information (NCBI), and the National Network of Libraries of Medicine, NLM Training Center (NTC). The course provides knowledge and skills for librarians interested in helping patrons use online molecular databases and tools from the NCBI. Prior knowledge of molecular biology and genetics is not required. Participating in the Librarian’s Guide course will improve your ability to initiate or extend bioinformatics services at your institution. Instructors will be NCBI staff and Diane Rein, Ph.D., MLS, Bioinformatics and Molecular Biology Liaison from the Health Science Library, University at Buffalo. There is no charge for the classes. Travel and lodging costs for the in-person class are at the expense of the participant.
There are two parts to A Librarian’s Guide to NCBI, listed below. Applicants must complete both parts. Participants must complete the pre-course with full CE credit (Part 1) in order to advance to attend the 5-day in-person course (Part 2). Part 1: Fundamentals in Bioinformatics and Searching is an online (asynchronous) course, January 12-February 13, 2015, and Part 2 is a 5-day in-person course offered on-site at the National Library of Medicine in Bethesda, MD, March 9-13, 2015.

September 16, 2004 is a special day in the history of PubChem. It marks the beginning of PubChem as an on-line resource! Now fast forward ten years. PubChem provides information daily to many tens of thousands of users. Despite the passage of time, PubChem’s primary mission remains the same: providing comprehensive information on the biological activities of chemical substances.
Providing chemical information to researchers in the biomedical science community is a key part of PubChem’s purpose. Over the years, PubChem introduced and incrementally developed several interfaces, each with its own distinct purpose and set of use cases. Primary to these is the Entrez search interface, where PubChem is organized as three distinct databases: Substance, Compound, and BioAssay. Substance provides substance descriptions (accession number: SID), Compound provides the unique small-molecule chemical content of Substance (accession number: CID), and BioAssay provides biological experiment results for substances (accession number: AID). Each of these databases has an advanced search interface and contain numerous indexes and filters, which can be combined to construct elaborate queries. Additional interfaces exist to search and analyze information in PubChem, including the ability to analyze bioactivity information, download chemical and assay data, search by chemical structure or protein sequence, navigate using integrated classifications, visualize chemical 3-D information, and more.
PubChem continues to evolve the way it provides on-line content. External search engines (like Google, Bing, and others) are now a key way in which researchers locate data. In addition, programmatic interfaces now account for a significant portion of PubChem’s overall usage (+50%). Key programmatic interfaces to PubChem include Entrez Utilities and PUG/REST.
The full RefSeq release 67 is now available on the NCBI FTP site with over 61 million records describing 45,166,402 proteins; 8,163,775 RNAs; and sequences from 41,913 different NCBI TaxIDs. More details about the RefSeq release 67 are included in the release statistics and release notes. In addition, reports indicating the accessions included in the release and the files installed are available.
