Beyond the golden rule of polymer network dynamics: Design principles for tissue-mimetic viscoelasticity.
Article in Science advances, 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
Technologies ranging from transportation to biomedical devices rely on soft materials whose performance hinges on balancing stiffness and damping. In conventional polymer networks, however, these properties are typically coupled: Softer materials are intrinsically more dissipative, reflecting a long-standing correlation in polymer dynamics that severely restricts the accessible design space. Here, we move beyond this longstanding constraint using brush-like polymer networks whose architecture in combination with chemistry governs viscoelastic response. By independently tuning strand volume and flexibility, we vary the elastic modulus over orders of magnitude while maintaining nearly constant relaxation time without altering network chemistry. Our findings establish a general framework for encoding viscoelastic responses in polymer networks, enabling the design of tissue-mimetic materials with programmable equilibrium stiffness and rate-dependent dissipation.
