A new study shows that systems designed to capture methane from cow manure, called dairy digesters, are highly effective. But on the rare occasions they fail, the leaks are large enough to offset ...

A giant, balloon-like tarp stretches over a lagoon of manure on a Central Valley dairy farm, concealing a quiet but remarkable transformation. Methane, a potent climate-warming gas, is being captured ...

Each year, a single cow can belch about 200 pounds of methane. The powerful greenhouse gas is 27 times more potent at trapping heat in the atmosphere than carbon dioxide. For decades, scientists and ...

Sometimes, answering a long-standing problem is a matter of finding a new perspective. Take methane from cows: For years, people have been trying to eliminate the gas from cow burps in an attempt to ...

To say that cattle have a complex stomach is a major understatement. They have four separate compartments in their stomachs that allows them to break down grass and grains, and turn it into protein.

When my daughter was ten years old, I dared her to put her hand in the stomach of a fistulated cow–hoping she would overcome the ick factor and learn something about cow digestion. If you have never ...

Methane is more than 80 times as potent as carbon dioxide at warming the atmosphere over a 20-year timeframe. In California, much of the methane comes from dairy cows. The gas is not just from the ...

Matthias Hess, with the UC Davis Department of Animal Science, and researchers at UC Berkeley, have identified which microbes in a cow's gut could help reduce methane. It brings them a step closer to ...
