YOU SMELL SO GOOD!:  Apparently, the smell of men and women is discernible to mice, and the smell of men induces anxiety, not just in mice, but several other studied species such as guinea pigs, dogs and cats.  Laboratories might be well advised to use more women to conduct certain experiments.

Relatedly, a new study shows that exposure to male and female hormones communicate gender to us, without any overt visual clues.  Apparently, women can smell men, and men can smell women.  “Interestingly, the researchers found that homosexual males responded to gender pheromones more like heterosexual females did. Bisexual or homosexual female responses to the same scents fell somewhere in between those of heterosexual males and females.”
