Male Pheromones Build Brain Cells in Female Mice

Researchers at the University of Calgary in Alberta have shown that female mice tend to create new brain cells when they detect a dominant male's urine, a discovery that outlines how chemical messages may shape their choice of mates. Dr. Samuel Weiss and his colleagues at the university l...

Mate or hibernate? That's the question worm pheromones answer

GAINESVILLE, Fla. If worms could talk, they might tell potential suitors, "I like the way you wriggle," complete with that telltale come slither look.

Past experience of pheromones induces dominant courtship behavior in fruit flies

By investigating the interplay between pheromone signaling and behavior in fruit flies, researchers have begun to understand how an adult fly's earlier experience as a young individual can influence its behavior towards other flies as an adult. In particular, the researchers found that pheromone si...
