BJ publishes original articles, letters, and perspectives on important problems in modern biophysics. The papers should be written so as to be of interest to a broad community of biophysicists. BJ welcomes experimental studies that employ quantitative physical approaches for the study of biological systems, including or spanning scales from molecule to whole organism. Experimental studies of a purely descriptive or phenomenological nature, with no theoretical or mechanistic underpinning, are not appropriate for publication in BJ. Theoretical studies should offer new insights into the understanding ofexperimental results or suggest new experimentally testable hypotheses. Articles reporting significant methodological or technological advances, which have potential to open new areas of biophysical investigation, are also suitable for publication in BJ. Papers describing improvements in accuracy or speed of existing methods or extra detail within methods described previously are not suitable for BJ.
Papers are handled by an Editorial Board of more than 100 scientists who solicit reviewers with the requisite expertise. The Editorial Board is divided among the following sections; these descriptions also serve to detail the scope of science published by BJ:

Section I—Nucleic Acids and Genomic Biophysics. This section highlights biophysical aspects of genome organization and their relation to cellular functions such as transcription, translation, development, and gene-regulatory mechanisms. It includes studies using experimental and computational techniques to investigate the structure, dynamics, function, and regulation of DNA, RNA, and their complexes with other molecules. It also publishes research studies on chromatin structural states, folding and function, and the dynamic organization of the nucleus.

Section II—Proteins. This section covers the biophysics of protein structure, function, and interactions. The emphasis is on molecular biophysics encompassing experimental, computational, and theoretical approaches.

Section III—Channels and Transporters. This section covers mechanistic studies of the structure, function, and regulation of membrane transport proteins and signaling receptors. The emphasis is on studies that use experimental and/or computational methods.

Section IV—Membranes. This section covers the analysis of the structure, organization, and function of artificial and biological membranes via state-of-the art experimental and theoretical biophysics approaches.

Section V—Molecular Machines, Motors, and Nanoscale Biophysics. This section covers biophysical studies of molecular motors (cytoskeletal and non-cytoskeletal), cytoskeletal assemblies, and muscle contraction and studies that use single-molecule tracking, force spectroscopy, and other nanoscale techniques.

Section VI—Cell Biophysics. This section covers work that furthers our understanding of molecular function and interactions within and between cells and elucidates how these mechanisms are regulated within the cellular milieu.

Section VII—Systems Biophysics. This section covers the analysis of collective properties in systems of interacting components, including biomolecular networks, organelles, tissues, organs, and whole organisms. Special emphasis is placed on studies that link multiple levels of biological organization, from gene sequence to nonlinear and network-level phenomena, such as pattern formation, metabolism, and signal transduction.
Section VIII—Biophysical Perspectives.
