When it comes to the Battle of the Sexes you may be surprised to hear this competition is a popular one in the field of health research. On Tuesday, September 22, 2014 the National Institutes of Health (NIH) announced that it will be distributing $10.1 million in grants to scientists and research facilities studying a host of topics, from drug addiction to migraines. These funds are intended to help support the inclusion of more research subjects, particularly females, in studies that require a little more representation of the XX chromosomes in their laboratory subjects. This means the participation of more female animals, even cell lines, in research laboratories. The remainder of the awarded money will be used to supplement analysis of gender differences in the studies’ resulting data.
