The specialty search site scirus.com, owned by science publisher Elsevier, is closing down.
A notice on the site says:
"We are sad to say goodbye
"Scirus is set to retire in early 2014. An official retirement date will be posted here as soon as it is determined.
"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."
Too bad, because this was a site I genuinely used to find scientific papers and abstracts.
