Working with researchers at the University of Wisconsin, Brown has been studying the feces of two pandas at the Memphis Zoo, Ya Ya and Li Li. So far her team has "identified bacteria that break down lignocellulose into simple sugars, which can be fermented into bioethanol," according to a press release from the American Chemical Society. "They also found bacteria that can take those sugars and transform them into oils and fats for biodiesel production."

So... Pandas are organic machines for turning bamboo into biofuel.
