 The work in the previous sections has focused primarily on examples of feminist perspectives in biology and the social sciences. This may not be surprising since in much of biology, sex is relevant and thinking about sex has been among the issues that feminists have explored. The social sciences examine various aspects of society and the way gender structures society has again been a major concern for feminists. Barad and the new materialists suggest ways in which feminist (and queer) critique can be extended to the physical/material sciences. There are other areas of scientific research that have also drawn the attention of feminists however. Two of particular interest are neurofeminism which focuses on sexism in the study of the brain and feminist critiques of the closely related field of cognitive science.
