More quick answers to the most frequently asked questions about global warming. Join Pamela Schaller from the California Academy of Sciences as she discuss penguins and how climate change impacts them. Penguin researcher David Ainley joins us via telephone from his tent at Cape Royds, Antarctica. Dr. Ainley has been studying Adelie penguins for many seasons from his remote encampment. Watch as Exploratorium physicists Paul Doherty and Stephanie Chasteen play around with the leading greenhouse gas: carbon dioxide. What is it? How much is there in our atmosphere? What does it do that is so harmful to the environment? Dr. Sydney Brenner won the Nobel prize in physiology or medicine in 2002 for his work with the tiny nematode, C. elegans.

In this program, he describes how new model organisms are established for studying basic physiology, recounts his reaction to seeing Watson and Crick's DNA model for the first time, and offers advice to young scientists just starting out. We explore behind the scenes in the "tank room" of the Darwin Centre, where thousands of biological specimens up to 300 years old are kept. Bat curator Richard Harbord and photographer Frank Greenaway explore questions about our furry flying friends in Belize. We also talk with bat experts in London and at the Exploratorium.
