It sounds like something from the movies, but it's true: Researchers unearth an organism frozen inside a glacier, take it back to the lab and discover it's still alive.

Brazil is a paradise for birds; the country has more than 1,700 species. Among them is the colorful toucan, a bird with an almost comically giant bill that can be half as long as its body. There are lots of different types of toucan — red-breasted, channel-billed, keel-billed, saffron toucanet — each with its own color-scheme and distinctive call.
