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.

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.
