Non-linear frequency-doubling up-conversion in sulfide minerals enables deep-sea oxygenic photosynthesis.
Article in National science review, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Visible light emission exceeding purely thermal radiation has been imaged at deep-sea hydrothermal vents, yet the underlying mechanisms remain unexplained. Here, we show that visible light can be produced from geothermal infrared radiation via nonlinear frequency-doubling up-conversion in sulfide minerals that are abundant in hydrothermal vents. Chalcopyrite exhibits significant second harmonic generation, which is further amplified under high pressure, yielding a 400-700 nm photon flux three orders of magnitude greater than blackbody emission. When exposed to 1064 nm of irradiation, chalcopyrite induces fluorescence responses in the cyanobacterium
