New research by professors at the University of Bristol suggests that biologists may be avoiding scientific papers that have extensive mathematical detail, Times Higher Education reported. The Bristol researchers studied the number of citations to 600 evolutionary biology papers published in 1998. They found that the most "maths-heavy" papers were cited by others half as much as other papers. Each additional math equation appears to reduce the odds of a paper being cited. Tim Fawcett, a co-author of the paper, told Times Higher Education, "I think this is potentially something that could be a problem for all areas of science where there is a tight link between the theoretical mathematical models and experiment."
