I'll be doing a live chat on BlogTV to help support Doctors Without Borders at 1:00 p.m. Mountain Time (19:00 GMT) today! Sorry about the short notice, but this just got arranged. I'll be on video, and you can go into the chat room to ask questions about astronomy, skepticism, or whatever. DWB is a great organization helping people all over the world, giving them desperately needed medical attention even at the risk of the doctors themselves. This series of chats with different scientists, entertainers and more is being held over the next day to raise awareness and money for the group, so if you tune in and you're able, please give whatever you can.
