Interesting. "Informatics" is definitely still in use at some places, so maybe this was another Americanism winning over in Britain. At any rate, it's "Informatik" in German, "informatica" in Dutch, "scienze dell'informazione" in Italian, "informatika" in Hungarian, "informatiky" in Slovakian. But the Russian version at least seems to be a literal translation of "computer science".
