Mid-IR Imaging Can Detect Waste Heat Production in the Nematode Caenorhabditis elegans.
Article in Journal of biophotonics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Organisms carry out metabolic processes to produce chemical energy, but these biochemical pathways are inherently inefficient, resulting in the loss of energy as heat. This study reports the first characterization of the thermal signature of waste heat production in the ectothermic invertebrate Caenorhabditis elegans using thermal infrared (8-10 μm) imaging. A label-free imaging approach was developed to distinguish the heat output of living versus dead C. elegans by employing a cold object in reflectance mode with a highly reflective imaging substrate to suppress the thermal background. This method reveals a clear, repeatable difference in both the thermal output and cooling rate of living versus dead worms. Fourier Transform Infrared (FT-IR) spectroscopy confirms that the measured temperature differences arise from variations in kinetic temperature rather than differences in thermal emissivity. This novel approach provides a powerful tool for studying the previously inaccessible thermal biology of small ectothermic invertebrates.
