Structuring light with flows.
Article in Nature communications, 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
Structured light has profoundly advanced optical manipulation, processing and imaging. However, its practical deployment in free space is limited by the constrained solutions of Helmholtz equation, which are bound to fixed propagation laws. Here, we reframe structured light as optical flows through a hydrodynamic description beyond the conventional field formalism, achieving flexible light structuring in free space via streamline engineering. Within this framework, we demonstrate the on-demand generation of diverse families of beams, with tailored propagation dynamics, including Gaussian, Bessel, Airy and vortex beams, and introduce specialized modes that overcome complex propagation challenges. To validate the designed energy streamlines, we perform optical tweezers experiments, treated as analogous to fluid particle-tracking velocimetry, demonstrating potential for high-precision optofluidic manipulation. For free-space optical communication, we show how vortex modes with a tailored flow can improve channel capacity, resilience to turbulence and non-line-of-sight capability. The hydrodynamic framework reported here provides precise control over light in free space, opening avenues in optomechanics, optofluidics, imaging, metrology, and communications.
