Enteric neurons, aka somatic postmitotic cells, must hold on to their sex identity tight, to deliver a tuned response to signals from the ovary that instruct the animal to engage sex-matched behavioural programmes.

How amazing!!! Well done everyone and esp Sarah Certel!
An important study maps how nerves control the Drosophila male reproductive tract, revealing two types of glutamatergic neurons that also release serotonin or octopamine.

Women cannot get it right. When we do so something at the level of the men, there must be a catch of why we succeeded, otherwise surely not. I am in fact quite tired of hearing such comments, on a regular basis as a young PI.
Have you ever heard that women have more chances than men of getting grants or positions in academia? Of course you have, and here are my personal views on this. With the shocking revelation that no, it is NOT TRUE ! (1/n)
