women in science redux

I have written before on the obstacles that face women in science, which included a link from Nature discussing the shortage of women in this and related fields. Now Pharyngula has a post on this theme, first mentioning the dearth of female recipients of recent European Young Investigator Awards, and a study that showed that this result was due to gender bias rather than inferior applications submitted by females. It also provides corroboration in the form of a (publicly-accessible) paper in Nature, "Nepotism and sexism in peer-review."  This study demonstrated gender bias in evaluating grant applications, such that a female would have to be far more productive (as measured by publications) than males to be considered equally competent.  In fact, it would be the equivalent of publishing about 20 papers in journals with an impact factor of about 3, or several papers in journals such as Nature or Science.  Whoa!  This was a European study, but there was a link in the comments to a similar study in the United States.
