Biomolecular and subcellular processes constitute a research area focused on the molecular mechanisms and dynamic interactions that underlie cellular function, organization, and regulation at nanometer to micrometer scales. It encompasses studies of protein folding and trafficking, nucleic acid structure and metabolism, signal transduction, membrane transport, organelle biogenesis, cytoskeletal dynamics, and macromolecular complex assembly. This field integrates biochemical, biophysical, structural, imaging, and computational approaches to quantify reaction kinetics, spatial organization, and emergent behaviors within cells, aiming to relate molecular-level events to higher-order cellular phenotypes, robustness, and dysfunction in contexts such as development, stress responses, and disease.
Biologists and computational scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory recently refined two artificial intelligence (AI) programs originally built by Meta, the company that owns Facebook, ...

Nucleons, which include protons and neutrons, are the composite particles that make up atomic nuclei. While these particles have been widely studied in the past, their internal structure has not yet been fully elucidated.
An international team of scientists has uncovered a surprising mechanism for how cells measure the length of messenger RNA (mRNA) tails. Rather than determining their size, cells time their growth with stopwatch-like precision. ...
