Breaking glass?

Why are women so under-represented at the top echelons of science? Why do so many drop out just as their careers should be blossoming? Are women in science being actively discriminated against by their peers, and, if, so what can be done about this? These were just a few of the puzzles reflected upon at a recent European meeting that examined the role of women in science. Thankfully, there is evidence that, today, there is real opportunity, as well as mere light, emerging through the ceiling that caps so many careers.
