Scirus website announce the retirement in early 2014. The message on the website looks like:

To ensure a smooth transition, we are informing you now so that you have sufficient time to find an alternative search solution for science-specific content.

Scirus is a comprehensive science-specific search engine. Like CiteSeerX and Google Scholar, it is focused on scientific information. Unlike CiteSeerX, Scirus is not only for computer sciences and IT and not all of the results include full text. It also sends its scientific search results to Scopus, an abstract and citation database covering scientific research output globally. Scirus is owned and operated by Elsevier.[1]
In 2013 an announcement appeared, on the Scirus homepage, announcing the sites retirement in 2014.
