"Penguins have no self-doubt."

If like me you've been wondering, what with Antarctica falling apart and all, what effect climate change may have on all those cute penguins (who I might also add, are the only wild animals left not afraid of humans).... I've got an NPR story that may interest you.  (Both text and audio.)  It's mostly about penguin research (plenty of penguin chatter in the background), though it's worth it just to hear the researcher comment, "They're never doubting themselves.  Penguins have no self-doubt.  Of course, which I have lots of, in myself."
