KALW just aired two pieces that I did on the rising rate of pregnancy related deaths and the black-white disparity. You can see a longer post from June. I'm hoping this will get more media attention - it's a particularly troubling example of the broader problem that Atul Gawande and others (and still others) have identified. How does this tie in with Nature? Well when you live in a world we look to science for all the answers, science sometimes ends up providing best-guess answers when it should just be saying - "we don't know enough about that yet."
