Overview: Today's episode of Daily Planet starts Jay Ingram visiting a group of researchers using science to predict avalanches. Then, there's no skating over this ice rink... figuratively speaking. Mark Miller shows us a 19-kilometer long outdoor rink. Plus, we go England where "metal music" takes on a whole new meaning with guitars made from tin boxes, hear from the Yukon Territories' Chief Paleontologist on how life was bloomed from a 30,000 year old seed found buried in the Siberian Tundra, and we kick off a special Mindbender with a spectacular Mythbusters grand prize! All this and more, tonight on Daily Planet.
