Stockholm, SWEDEN: Hakan Wennerstrom (L), and Per Ahlberg of the Royal Academy of Sciences try to explain this year's Nobel Prize in Chemistry awarded to French Yves Chauvin and Americans Robert H. Grubbs and Richard R. Schrock by dancing with Malin Lindgren (L, hidden), and Eva Krutmeier (C), also of the academy, behind them. After the dance -- purporting the likeness of molecules changing partners -- they formally announced the winners at the academy in Stockholm 05 October 2005.
