How Women Pick Mates
Science might be able to explain our fascination with Brad Pitt's chiseled jaw and George Clooney's smoldering eyes.Women seem to judge potential mates by how masculine their features are, new research shows. Men with square jaws and well-defined brow ridges are seen as good short-term partners, while those with more feminine traits such as a rounder face and fuller lips are perceived as better long-term mates.In the study, 854 male and female subjects viewed a series of male head shots that had been digitally altered to exaggerate or minimize masculine traits.

Love More Powerful than Sex
Sex and romance may seem inextricably linked, but the human brain clearly distinguishes between the two, according to a new study. The upshot: Love is the more powerful emotion.
The Rules of Attraction in the Game of Love
To figure out how we pick mates, scientists have measured every shape and angle of the human face, studied the symmetry of dancers, crafted formulas from the measurements of Playboy models, and had both men and women rank attractiveness based on smelling armpit sweat.After all this and more, the rules of attraction for the human species are still not clearly understood.
Altruistic Love Related to Happier Marriages
Altruism may breed better marriages, a new study suggests. Or, the data might mean that good marriages make people more altruistic.Whatever, altruism and happiness seem to go together in the realm of love.
