The Love Hormone's Dark Side
With Valentine's Day just around the corner, love is in the air. Or is it oxytocin? Research suggests that the so-called "love hormone" isn't all roses and heart-shaped chocolates.
Oxytocin is marketed as an all-purpose "love drug" year-round. Online, sellers shill a product called "liquid trust" that purports to contain oxytocin and promises to create an "environment within which you are more attractive to people you previously had no luck with." In San Antonio, Texas, at least one doctor prescribes dissolvable oxytocin strips for husbands and wives going through rough patches, according to a Feb. 10 news report by local news station KENS5. Even cultural and political commentators have touted oxytocin's effects, arguing that the hormone makes no-strings-attached sex impossible, especially for women.

A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- Octopuses, like humans, have genes that seem to code for serotonin transporters.
- Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
- Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
