Rats are the most common pest people worry about. Scientists from Simon Frasier University have figured out a way to exterminate these rodents by identifying and artificially copying the male brown rat's sex pheromone and luring the female brown rats into traps.
It turns out that ants can sniff out body odor to tell friend from foe. Scientists have discovered that these insects manage recognition based on chemical pheromones, which they sense with their antennae.
Does our sense of smell have anything to do with sexual attraction? New findings published in the journal Cell show that that it does, at least, for mice.
Can pheromones really help us get a date?
