Pheromones: The secret signals in human sweat

EVER had a feeling come over you that you just can't explain? Like suddenly getting all warm and fuzzy when you meet someone for the first time, while somebody else who looks just as good leaves you cold? Or experiencing a sudden pang of fear on a plane even though you're totally at ease with flying?

These seemingly unrelated and illogical human reactions may have a reasonable explanation after all, although one that not everyone will be happy to hear. They may be reactions to other people's pheromones.

Pheromones are something of a sensitive subject in human biology. Though they are found across the animal world from insects to mammals, research into human pheromones has been dogged by flaky experimental designs and dubious commercial endorsements, with the result that the entire field has a whiff of the disreputable about it.

In recent years, though, this has begun to change. Evidence that animal pheromones don't always work in they way we thought, backed up by a growing number of brain-imaging studies in humans, is convincing some researchers that we really do make and respond to pheromones. As a result some think it's time to stop asking if human pheromones exist and start investigating exactly how they affect our behaviour.
