Researchers go ‘cuckoo’ over Antarctic penguin poop

AFP – Antarctica’s king penguins emit such copious amounts of nitrous oxide, or laughing gas, via their faeces that researchers went a little “cuckoo” studying them,  according to a Danish scientific study published last Thursday. “Penguin guano produces significantly high levels of nitrous oxide around their colonies,” said the head of the study, Professor Bo Elberling, of the University of Copenhagen’s Department of Geosciences and Natural Resource Management.
