Dynamical properties of liquid condensates can be quantitatively assessed by combining phase separation theory and photobleaching, which opens new avenues to understand their physicochemical properties and functioning.
All-atom molecular dynamics simulations revealed both direct and indirect salt effects and led to an amino-acid composition-based predictor for four classes of salt dependence of IDP phase separation.
Multi-scale simulations reveal a potential, ATP-independent mechanism resulting in the formation of the long-living multi-droplet state by multi-valent, spacer-sticker proteins.

Charge complementarity between RNA and proteins may be a universal principle for phase separation in biology without requiring disorder or specific multivalent interactions.
TGN46 is a cargo receptor, with its luminal domain being necessary and sufficient to load soluble secretory proteins into transport carriers for export out of the trans-Golgi network.
The LINE-1 retrotransposon protein, ORF1p, forms a condensate on RNA that is essential for retrotransposition, and may explain cis-preference through a co-translational assembly mechanism.
The combination of optical diffraction tomography and Brillouin microscopy in a single setup enables to quantitatively map the viscoelastic properties of cellular compartments such as aggregates and stress granules in vivo.
