Monogamists have bigger brains. More precisely, female monogamy in bats makes their male partner's brains bigger and their balls smaller, while female promiscuity in another bat species caused males to have huge balls and teeny brains. Can trusting your partner not to cheat lead to greater intellectual greatness? Via.

Scientists find rodent monogamy gene. Emory researchers say that a single gene can change promiscuous rodents into faithful partners. Insert a certain gene of the monogamous prairie vole into the brain of the normally slutty meadow vole, and suddenly the meadow vole stops going to bars and hitting on other field mice. Previously, the same scientists' extensive research uncovered a vole sociability gene. In addition to its implications for autism and Asperger's Syndrome, the study could spawn the next reality show hit, "Who Wants a Monogamy Implant?" (Would you do it, if you could?)
