Nothing says "I'm single and ready to mingle" like a dose of salty digestive fluid. For sea lampreys, anyway. Male sea lampreys use a type of bile salt, which is more typically known for digesting fats, to advertise their genetic fitness to females and readiness to mate, new research shows. This stands in contrast to silver lampreys, which use the enzyme for digestion and other nonsexual functions, said Weiming Li, a researcher at Michigan State University.

The Museum of Sex has opened its own cocktail bar with rotating artist-designed drinks, and one of the first is called Lickable Skin. It's meant to taste like kissing an older man who has just shaved and smoked a cigarette.

"I like to play with the notion of being awkward and the sensation of awkwardness," its creator, Dutch artist Bart Hess, told Hyperallergic. This is the first food art that Hess has created, although he said that he "always lets the material decide which discipline he will work in." The drink is part of his ongoing interest in liquids, which manifests in experiments with "slime art" (including in a Lady Gaga video), forming hot wax in water, and in videos like "Shaved," playing in the new bar.
