Outgassing
News of the gross: researchers at the Swedish University for Agricultural Sciences will soon be taking stock of cow burps. Why? Because cow belches are unfortunate beasts: they contain lots of methane, and contribute, possibly, to our planet's greenhouse warming.
Twenty Swedish cows will don special methane-detection collars (since 95% of the methane cows release is expelled through the mouth). The cows will then be fed different diets, and presumably demonstrate correlating levels of rude behavior.
