What to know about Cell biochemistry beyond membranes: Condensate physics reveals general rules for chemical responses

Researchers at Cornell University and other institutions have developed a new experimental metric and theoretical framework to understand how biomolecular condensates respond to chemicals. This approach aims to move beyond traditional phase diagrams to better understand cellular physiology and potentially identify drug targets for neurodegenerative diseases.
