How will 2007 be remembered in the science history books? The awarding of the Nobel Peace Prize to Al Gore and the IPCC put climate change in the spotlight this year.

And while the space shuttle program continued to limp along close to Earth, robotic probes continue to send back impressive finds about the other planets in our solar system.
Join Ira and guests for a look back at the top science stories of the year -- and call in with your favorites. What big stories managed to slip under the radar of the media?
