To work out what the pheromones are doing, the team needed to somehow expose the flies to these smells without actually allowing them to mate. The problem with fruit flies is that their sperm is toxic and every sexual encounter shortens the lives of females. Now they’ve found that sex pheromones can do the same. In 2007, his team showed that the mere smell of food can influence the lifespan of flies. Meanwhile, Scott Pletcher from the University of Michigan found similar patterns in fruit flies. The team proved this by showing that mutant males which don’t produce pheromones don’t kill their mates early, while mutant hermaphrodites that can’t sense pheromones are immune to the males’ life-shortening powers. The males must be secreting some type of pheromone that stays in their environment and curtails the lives of the opposite sex. Their movements slowed, their bodies deteriorated, and their lifespans shortened by some 20 percent. But Brunet’s postdoc Travis Maures found that sterile hermaphrodites still suffered in the presence of males… and even in their absence! When he added hermaphrodites to containers that had previously housed males, they still aged more quickly. Other scientists had noticed the same effect 17 years earlier, but they assumed that it was due to the “stress of copulation”. While studying the nematode worm Caenorhabditis elegans, Anne Brunet’s team from Stanford University noticed that males seemed to shorten the lives of the opposite sex (hermaphrodites, whose bodies are female but who make both eggs and sperm). Just by being around, one worm or fly can control the ageing process in another, at a distance. Two teams of scientists have found that in worms and flies, the scent of pheromones from the opposite sex can speed up an individual’s ageing process and shorten its life. Your bloodstream courses with insulin, preparing your organs to absorb the nutrients that you’re about to consume.īut smells can have even more profound effects. You start to produce more digestive enzymes. Inhale the vapours of an apple pie or a bacon sandwich, and your body immediately starts getting ready for an incoming meal.
