An Archean atmosphere rich in sulfur biomolecules.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The abiotic production of sulfur-containing biomolecules under mild and globally relevant conditions has been an elusive endeavor in prebiotic chemistry experiments. As a result, a disconnect has emerged between understanding the origins of life and the later stages of biological evolution; the former potentially occurred independent of sulfur while the latter is universally dependent on it. Here, we demonstrate that planetary organic haze chemistry produces a suite of sulfur biomolecules including cysteine, coenzyme M, taurine, and potentially methionine and homocysteine. These compounds may form high in the atmosphere and subsequently deposit to early surface environments in sufficient amounts to support a budding global biosphere. Our findings thus challenge long-standing assumptions that sulfur biomolecules such as cysteine must have been biological "inventions."
