original description

<blockquote>Scientists have been able to take control of flies' brains to make females behave just like males. Researchers genetically modified the insects so that a group of brain cells that control sexual behaviour could be "switched on" by a pulse of light. ... To investigate, the team placed some flies in a "mini sound studio". The insects had been genetically modified so that a pulse of light would activate this group of courtship neurons. - <a href="http://news.bbc.co.uk/2/hi/science/nature/7350403.stm">bbc</a> </blockquote>
