Live Chat: Why Aren't There More Female Scientists, Engineers?

I heard an story about this Live Chat: Why Aren't There More Female Scientists, Engineers? on the News Hour yesterday evening. I am reading about this on PBS's website for the News Hour at (http://www.pbs.org/newshour/rundown/2012/04/stemchat-why-arent-more-women-in-science-and-engineering.html). A live chat is scheduled for noon ET Friday, April 27, with Judy Woodruff.
