Abstract: Based on the Science Citation Index-Expanded web-version, the 
USA is still by far the strongest nation in terms of scientific 
performance. Its relative decline in percentage share of publications is 
largely due to the emergence of China and other Asian nations. In terms of 
citations, the competitive advantage of the American "domestic market" is 
diminished, while the European Union (EU) is profiting more from the 
enlargement of the database over time than the US. However, the USA is 
still outperforming all other countries in terms of highly cited papers 
and citation/publication ratios, and it is more successful than the EU in 
coordinating its research efforts in strategic priority areas like 
nanotechnology. In this field, the People's Republic of China (PRC) has 
become the second largest nation in 2005 in both numbers of papers 
published and citations behind the USA.
