A sharp (twofold) increase can be observed over the past decade in the total amount of competitive research grant twins, the vast majority of which (approximately 80%) consists of National Science Foundation and European R&D Foundation wins. The highest number of wins was observed in the fields of medicine and life sciences (approximately 40% of all wins), and this persisted over time (relatively), but the most significant increase in percentage points was observed in the fields of engineering, mathematics and computer science, whose total number of wins grew 2.5-fold since 2009.
