Penguin excrement may contain laughing gas, study suggests

Morning News

A study published in the journal Science of the Total Environment suggests penguin excrement may contain laughing gas.

Researchers looked at the guano from king penguins in Antarctica and found when their feces hits the ground, it reacts with the soil and creates nitrous oxide.

Since penguins eat a lot of fish — and since fish are high in nitrogen, it could explain the phenomenon.

One researcher studying the penguins said he felt the effects of the nitrous oxide first-hand.
