Polygamy vaccine can become a reality.

Once again researchers blow up our minds: this time they declare the find of a gene responding for social behavior of animals. Sounds intriguing! That tiny thing, known as vasopressin receptor, is located inside the “reward center” deep in our brains. Scientists state that this gene will help them to learn more about neurobiological features of “romantic love” as well as better understand autism disorder (that thing affects the way people form their social bonds).

During the study the gene was transferred from monogamous male prairie voles (those small rodents form long-term - lifelong! - relations with their mates) into the brain of meadow voles (those guys lead the life of a Lovelace, considering that one partner is not enough for them). The result of that experiment striking: few days later “modified” meadow vole males became exemplary family men huddling close to their “better halves.” Of course, economic, historic, social and individual features make experiment's results not that definite for human beings. Still, “it is intriguing to consider that individual differences in vasopressin receptors in humans might play a role in how differently people form relationships,” says Larry J. Young, PhD of Emory University's School of Medicine.
