The hidden limit in light: intrinsic noise reshaping Brillouin metrology.
Article in Light, science & applications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Spontaneous Brillouin scattering is widely used to probe the mechanical and thermal state of matter, yet it has been assumed to be intrinsically stable. Jin and colleagues overturn this view by showing that spontaneous Brillouin light carries its own thermally driven noise floor. Their framework predicts-and experiments confirm-a universal upper bound of SNR = 1 under ideal detection conditions which can become even more restrictive than the conventional shot-noise limit in practical Brillouin systems. This discovery introduces a new fundamental limit to Brillouin-based sensing, microscopy and metrology.
