The thermodynamic state map of biomolecular condensates.

The thermodynamic state map of biomolecular condensates predicts measurable material changes and links code disruption to pathogenic liquid-to-solid transitions.

• Why it matters: Understanding how biomolecular condensates regulate cellular biochemistry is crucial, as their disruption can lead to disease-related phase transitions and organelle damage.
• What they did: The authors develop a thermodynamic state map integrating cellular inputs, molecular grammar, and boundary conditions, based on frameworks like stickers-and-spacers, to describe condensate material states.
• The result: This model predicts changes in partitioning, viscosity, and fibril-nucleation kinetics, enabling physical therapeutics that can remodel pathological states by targeting localized anti-cohesive effects.
