It should probably tell us something that the most frequently asked question on Google last year was “What is love?” Clearly, most of us are clueless on the matter; otherwise we wouldn’t be turning to algorithms for an explanation.

Which explains why scientific research on love continues unabated. We want answers.

So, on the eve of Valentine’s Day, here are 10 recent studies or surveys trying to make sense of matters of the heart.

1) You light up my brain: Researchers at Brown University in Rhode Island say that based on brain scans, they may be able to predict if a relationship will last. The scientists did MRIs on 12 people who said they were passionately in love, then repeated the process three years later. In the six people whose relationships lasted, the scans showed that the part of the brain that produces emotional responses to visual beauty was particularly active when they were shown a picture of their partners. But those same six had lower levels of activity in the pleasure center of the brain tied to addiction when they looked at the photo.

2) Yeah, but what did it do for their sinuses?: Scientists continue to ponder the effect of oxytocin, the so-called “love hormone” produced by the pituitary gland. One of more recent studies, at the University of Zurich, found that while men generally withdraw during conflict with their mates, those who inhaled an oxytocin nasal spray smiled more, made eye contact and generally communicated better during disagreements.

3) What you see is what you don’t get: A new study by sociologist Elizabeth McClintock at the University of Notre Dame concluded that highly attractive women are more likely to seek exclusive relationships than purely sexual ones, and also that, for women, the number of sexual partners decreases as their physical attractiveness increases.

4) Okay, now let’s try a salsa beat: Meanwhile, at the University of California, Davis, scientists studying the physical behavior of couples in relationships found that when they were sitting near each other–but without speaking or touching–their breathing patterns and heartbeats often matched up. The researchers also discovered that the women tended to adjust their behavior to their partners more often.

5) So yes, putting the toilet seat down is an act of love: A professor at the University of Rochester who’s been studying newlywed couples for the past several years says members of married couples who do small acts of compassion and thoughtfulness for each other usually have happier relationships. Researchers Harry Reis also found that men more often said that they had put their partner’s wishes ahead of their own.

6) As they say in the relationships biz, it’s complicated: According to a study soon to be published in the journal Psychological Science, people like to believe that their way of life–whether they’re single or in a couple–is the best choice for everyone. The researchers also found that when it came to Valentine’s Day, people believed that their friends would be happier if they were in the same situation as they were–in other words, people in a couple thought their single friends would enjoy themselves more on Valentine’s Day if they were in a relationship, while singles thought their coupled friends would have a better time if they were single.

7) Thanks for not sharing: And apparently it’s not such a good idea to make big displays of affection on Facebook. So say researchers at the University of Kansas who discovered that people don’t like their partners sharing their feelings about their relationships with the Facebook universe. Participants in the study said they felt less intimacy with their partners if they went public with how they felt about their loved one.

8) Another reason not to do windows: Here’s one to stir up debate. According to a research team of American and Spanish scientists, men who share in the housework have sex with their wives less often than men in “traditional” marriages where the women handle all of the household chores. This runs counter to previous studies which concluded that married men had more sex in exchange for helping around the house. In the recent study, married couples reported having more sex if the women did the cooking, cleaning and shopping and the men did the gardening, electrics and plumbing, took car of the car and paid the bills.

9) Road trip!: A survey of more than 1,000 American adults found that couples that travel together have better sexual relationships than those that don’t. Almost two-thirds of those surveyed recently by the U.S. Travel Association said that a weekend vacation was more likely to spark up their relationship than a gift. And almost 30 percent said their sex life actually improved after traveling together.

10) Which is why you don’t take dogs on vacations: On the other hand, dogs may not be so good for your sex life. About 73 percent of dog owners who answered another survey said their pets get jealous when they show physical affection toward their partners. And it probably doesn’t help that almost as many of those surveyed said their dog sleeps with them in bed.
