Cow Stomach Structure Produces Hydrogen, May Impact Methane Emissions

A newly discovered structure within cow stomachs may influence methane emissions. The structure produces hydrogen and exists within the microbes of cows. The findings were published in the journal *Science*.

Cows emit significant amounts of methane gas when they burp, which contributes to greenhouse gas emissions. The newly discovered hydrogen-producing structure within the microbes in cow stomachs could potentially affect the amount of methane gas expelled.
