Even though science is becoming increasingly competitive, scientists are still very willing to share their work with colleagues. This is especially true for male scientists among each other and less so for females among each other or between the sexes. These patterns of sharing among scientists were discovered by a team of Austrian, Dutch and German researchers led by Jorg Massen of the Department of Cognitive Biology at the University of Vienna, and the results of their study have been published in the scientific journal "Scientific Reports".
