Discovery of vast sex differences in cellular activity has major implications for disease treatment
"We discovered a pronounced 'men are from Mars, women are from Venus' pattern," says marine and environmental biologist Suzanne Edmands.

A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. Most sexual organisms have two sexes. In many cases, sex determination is genetic: males and females have different alleles or even different genes that specify their sexual morphology. In animals, this is often accompanied by chromosomal differences. In other cases, sex is determined by environmental variables (such as temperature) or social variables (the size of an organism relative to other members of its population). The details of some sex-determination systems are not yet fully understood.
