A cow stands in an enclosure at UC Davis in Davis, California on October 23, 2024. Researchers are studying other cows at the facility to develop ways to reduce methane emitted from cow burps. Paulo de Meo Filho, a postdoctoral researcher at University of California, Davis, is part of an ambitious experiment aiming to develop a pill to transform cow gut bacteria so it emits less or no methane.
