This latest report, Global Research Report: United States, found that:
In 1981, US scientists fielded nearly 40 percent of research papers in the most influential journals, by 2009, that figure was down to 29 percent.
The US demonstrates heavy output in health and biomedical research, in line with the nation’s investment focus, with a significant skew away from previous focal strengths in physical sciences and engineering
Though total volume output has not risen as quickly as Europe and Asia, average influence of research papers remains high at 40 percent above the world average
The structure of the US research base may be a contributing factor to its current position. The 61 US members of the Association of American Universities (AAU), for example, now account for 56 percent of US output in the five-year period to 2009
Though the US is still a dominant force in the global scientific research landscape, this prominence is being significantly challenged by increased competition from Europe and Asia
