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.

Jellyfish reveal rapid repair system behind scar-free healing

A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells "walk" toward each other to close a wound for the first time. An associate professor of molecular genetics and cell biology ...

How boundary geometry helps embryonic cells organize themselves

One of the most striking biological transitions in nature happens early in development, when an embryo transforms from a simple ball of cells into a highly ordered structure with distinct tissue layers that later develop ...

Slime molds make decisions using internal fluid flows

Despite lacking brains or nervous systems, slime molds are capable of making surprisingly sophisticated decisions: navigating mazes, finding food and even remembering where they found it last time. How they manage to do all ...
