Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.Abstract Top‐down studies of methane (CH4) emissions often use the average ethane‐to‐methane (C2/C1) ratio of wellhead gas in a basin to attribute emissions to thermogenic or biogenic sources. Biogenic CH4 sources (ruminants, wetlands, landfills, and other methanogenic sources) do not co‐produce ethane (C2H6); the presence of C2H6 indicates a ...

AI Magazine, Volume 47, Issue 3, Fall 2026.Abstract The AI alignment problem has resisted a wide range of technical approaches developed to address it, and we argue this persistence reflects shortcomings in the dominant paradigm itself rather than in any particular technical approach within it.
