A dominant subgroup of marine Bathyarchaeia assimilates organic and inorganic carbon into unconventional membrane lipids.
Article in Nature microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Bathyarchaeia, an abundant and ecologically versatile archaea found commonly in marine sediments, has a key role in the global carbon cycle. However, its lipid biomarkers and carbon assimilation mechanisms are poorly understood. Here, using a highly enriched Bathyarchaeia culture (>95% archaea) obtained from estuarine sediment of the East China Sea, we show that Baizosediminiarchaeum (formerly subgroup Bathy-8), the most abundant and widespread Bathyarchaeia group on Earth, synthesizes butanetriol dialkyl glycerol tetraethers (BDGTs) as its dominant membrane lipids. BDGTs are unusual archaeal tetraether lipids characterized by a butanetriol backbone instead of the typical glycerol, challenging fundamental assumptions in archaeal lipid biochemistry. Although BDGTs have been previously identified in the methanogen Methanomassiliicoccus luminyensis, we now provide direct evidence that Bathyarchaeia also synthesizes BDGTs, definitively establishing this globally abundant group as a natural BDGT producer.
