Here are 10 tidbits to use as conversation fodder (or just to consume privately) from recent studies about love and mating. Some of them are pretty well thought out, others suffer from potential empirical problems. They are all somewhat fun nonetheless.

A sample:

6. It’s official. Love makes us crazy. For one, it causes serotonin levels in the brain to drop, which may lead people to obsess about their lover. (The levels of serotonin, a chemical produced by the body, are also low in people who have obsessive-compulsive disorder.) Next, it ramps up production of the stress hormone cortisol, leading to slightly higher blood pressure and possible loss of sleep. Finally, a scientist at the University of London has found that when people look at their new loves, the neural circuits that are usually in charge of social judgment are suppressed. All in all, love kind of leaves you obsessive, stressed, and blind. And we love it.
