Optically driven control of mechanochemistry and fusion dynamics of biomolecular condensates via thymine dimerization.
Article in Nature communications, 2026. 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
Phase-separated biomolecular condensates are functional elements in cells, contribute to protocell formation in prebiotic systems, and represent a distinct class of soft matter. Controlling condensate mechanochemistry is critical for function and material properties. Although photochemical processes are widespread in nature and can be harnessed in engineering, it remains unclear how condensate formation affects photochemistry, and conversely how photochemistry alters condensate dynamics. Using scanning probe microscopy combined with UV-controlled photochemistry and optical imaging, we develop assays to probe mechanical transitions and fusion dynamics in condensate droplets, revealing that UV-induced thymine dimerization alters condensate nucleation and coalescence. Depending on the frequency and topological arrangement of thymine dimers, particularly the balance between inter- and intrachain crosslinks, UV can drive transitions from liquid-like to solid-like states or induce aggregates. UV also promotes arrested fusion and stable compartmentalization of droplets, resilient to environmental changes and with implications for prebiotic chemistry and bio-inspired engineering.
