Circularly polarized luminescence as a contingency assay for 'mirror life' bio-hazards.
Article in Royal Society open science, 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
Mirror life presents a low-likelihood but high-severity global biosecurity threat that has attracted the attention of bioscientists, governments and international security organizations. However, current analytical techniques are not fit to identify mirror life biohazards. Herein, we propose the first assay method for screening against mirror life. This approach is based upon optical circularly polarized luminesce (CPL) signatures generated by fluorescent probes, which bind to subcellular targets (e.g. membranes, organelles, nucleic acids, etc.). Probes can either be achiral or be intrinsically chiral. We set out why a multi-probe reporter panel approach incorporating many CPL-generating probes is necessary to identify mirror life with a high degree of confidence (i.e. avoiding false positives). The distinct CPL signatures can be analysed via recent innovations in CPL detection, i.e. rapid CPL spectroscopy, CPL microscopy (enantioselective differential chiral contrast, EDCC, imaging) and CPL EDCC cameras. While these are advanced technologies, they share the same fundamental optical principles as three-dimensional cinema glasses and so are amenable to scaling and portable applications. The CPL assay approach to mirror life screening could be a useful tool for screening against mirror life biohazards and ensuring compliance with any potential future international legislation against mirror-life research.
