New study by the Behaviour & Metabolism lab reveals that a small group of sex cells instruct a fundamental behavioural change in the female fruit fly – developing a sweet tooth.

Sex cells have a sweet tooth, and they pass it on to the brain

In a study performed in fruit flies, a team of scientists at the Behaviour & Metabolism Lab, make a surprising discovery. Their results, published in the scientific journal Nature Metabolism, reveal that changes in the nutritional requirements of sex cells make female flies crave sugar. Until now, this phenomenon was mainly described in pathological conditions, namely cancer. Its discovery in the normal physiological process of egg formation, provides important insight into the link between fertility and nutrition.
