Peptide in male fruit fly semen found to enhance memory in females after mating
(PHYSorg.com Biology)

A quartet of researchers with PSL Research University, CNRS, has found that a peptide in male fruit fly semen somehow makes its way to the female fruit fly brain after copulation, resulting in improvements in long-term memory. In their paper published in the journal Science Advances, L. Scheunemann, A. Lampin-Saint-Amaux, J. Schor and T. Preat describe their study of memory in fruit flies and what they learned.
