Research news on Cells

Cells, as physical systems, are discrete, membrane-bound units of biological organization that maintain non-equilibrium thermodynamic states through regulated exchanges of matter and energy with their environment. They comprise structurally organized macromolecular assemblies—primarily lipids, proteins, nucleic acids, and carbohydrates—partitioned into distinct compartments (e.g., cytosol, organelles) that support specialized biochemical networks. These systems exhibit emergent properties such as signal processing, self-replication, and adaptive response, governed by gene expression programs and biophysical constraints. At multiple scales, cells function as fundamental units of structure and function in organisms, integrating mechanical, chemical, and electrical processes within a dynamically regulated spatial architecture.
