Found this in the Detroit News (via the Boston Globe): Female scientists weigh benefits of lab-vs.-life goals. Unfortunately, it is nothing but a case study of a Harvard biology grad student with a 1-year-old who urges her undergrads to combine careers in science with a family but who is contemplating dropping out of grad school because she can't imagine holding a research job and raising her son.
The article provides no real numbers on the frequency of this situation (no context), no suggestions for what can be done to help women in this situation, and no indication of where the child's father is.
I suppose an article like this might raise the awareness of some newspaper readers - yes, Virginia, there are women grad students who have kids. But I suspect that some reading it will just say, "that's what she gets for trying to have it all" while others will say "another example of societal barriers for women." But neither response advances the discussion. Frustrating!
