New Organelle in Cow Stomachs Could Impact Methane Emissions

A newly discovered structure within cow stomachs may influence methane emissions, according to research published in the journal *Science*. The finding relates to a hydrogen-producing structure within the microbes of cow stomachs.

Cows release a substantial amount of methane gas into the atmosphere when they burp, which makes them a leading contributor to greenhouse gas emissions. The study suggests this newly discovered organelle could play a role in reducing the amount of methane expelled.
