Review: Genetic and genomic selection as a methane mitigation strategy in dairy cattle

Animal, 2020
Over the last decade, extensive research effort has been placed on developing methane mitigation strategies in ruminants. Many disciplines on animal science disciplines have been involved, including nutrition and physiology, microbiology and genetic ...

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Inefficient consumption of natural gas drives methane emissions from a megacity [PDF]

Atmospheric Chemistry and Physics
Reducing methane emissions offers a significant near-term opportunity for climate mitigation if the dominant sources are effectively targeted. Natural gas is a large and manageable methane source.

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction

Advanced Science, EarlyView.
Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Methane Emissions from Livestock Operations: Sources, Sinks, and Mitigation Strategies

Methane
Livestock operations significantly contribute to global methane (CH4) emissions, a potent greenhouse gas. This occurs primarily through enteric fermentation (a digestive process in ruminant animals that produce methane) and manure management. This review

The rumen microbiome inhibits methane formation through dietary choline supplementation

Scientific Reports, 2021
Enteric fermentation from ruminants is a primary source of anthropogenic methane emission. This study aims to add another approach for methane mitigation by manipulation of the rumen microbiome.

Ferroelectric Catalysts in the Hydrogen Evolution Reaction: A Perspective

Advanced Science, EarlyView.
This perspective summarizes recent advances in ferroelectric (FE) catalysts for the hydrogen evolution reaction (HER). It first introduces HER fundamentals and FE mechanisms, then classifies FE catalysts into single‐phase, single‐atom‐modified, heterostructured, and other engineered types, with representative examples.

Nitrogen-fixing methane-utilizing bacteria [PDF]

, 1976
Methane occurs abundantly in nature. In the presence of oxygen this gas may be metabolized by bacteria that are able to use it as carbon and energy source.
