Peer Review Gender Biases in Science

Well, I just finished being part of a panel discussion on women in science.  Depressing!  While other disciplines are routinely double blind reviewed, the science community keeps embracing the good 'ol boy system using gender, name, race, institution etc as biases.  I wonder why that hasn't hit the press yet?!  Biases?!  Statistics prove that the gender bias during peer review makes a difference of 33% in acceptance rates.
