NCBI stands for National Centre for Biotechnology Information. It is a website created by the US government that is used to compile scientific articles, gene sequences, protein sequences and structures for use by the scientific community. Scientific papers are uploaded from scientific journals, sometimes before the paper has even been published. BLAST, a sequence database tool and PubMed, a database of journels, are some of the most useful tools for Biosciences students.
In October 2013 the NCBI webpage went a number of days without an update. The shutdown lasted 16 days and returned to working function on October 17th; along with the scientists working there. This was due to their funding being frozen due to the US government shutdown. During the shutdown PubMed indexed no new articles and very few journals.
