Cooperation is the key in the gas‐phase formation of ethene by gold‐dimer cations. As the cycle in the cover picture shows, two methane molecules are required to initiate the dehydrogenation step. A third methane molecule then cooperatively triggers the release of ethylene. The background shows submarine methane evolution, which represents an important geological methane source. In their Communication on page 980 ff. T. M. Bernhardt, U. Landman, and co‐workers present the results of their combined gas‐phase and theoretical investigation.
