Knowledge , networks and nations Global scientific collaboration in the 21st century

Abstract

Science is a global enterprise. Today there are over 7 million researchers around the world, drawing on a combined international R&D spend of over US$1000 billion (a 45% increase since 2002), and reading and publishing in around 25,000 separate scientific journals per year. These researchers collaborate with each other, motivated by wishing to work with the very best people and facilities in the world, and by curiosity, seeking new knowledge to advance their field or to tackle specific problems.
