I met Prof. Barres at my Stanford interview weekend; he gave a talk about the new Master of Medicine program (which I came very close to applying to, it sounds like a fantastic setup). It also turns out that he is a friend of my current boss. Small world.
In any case, he just had a piece published in Nature that is stirring up some controversy. He has the unique position of understanding what it is like to be a woman as well as a man in science; he used to be a she. (and no, when I met him, I had absolutely no idea of that.)
My rant on why there aren't more women in science only touched the tip of the iceberg. I was thinking along the lines of support for the women who do manage to make it. There's still a long way to go to help those who are capable but never even get that far.
