The new ranking shows a broad general trend of improvement. In the previous ranking, nearly all of the research fields were in negative territory in terms of their relative impact compared to the world, apart from mathematics and the agricultural sciences. In the recent ranking, there is significant improvement with several fields actually having above average impact (materials science, mathematics, plant & animal sciences, pharmacology and agricultural sciences).
In the physical sciences and engineering, most fields showed improvement except for computer science.
In the biological sciences, on average, there was improvement although the results are stagnant for microbiology, molecular biology and biology & biochemistry.
In the medical sciences, on average, there was good improvement, especially pharmacology which improved by a whopping 45 percent to garner an above average score. Not surprising considering the amount of research support pharmacological research has received in recent years. Again, there is obvious room for improvement since most of the fields are still deep in negative territory.
