Biophysics and Physicobiology (BPPB) is the official on-line journal of the Biophysical Society of Japan (BSJ). Biophysics has long been developed in a field of physics using physical methods and theories to study the structures and functions of biological systems. Biophysics now spans all scales of biological organization, from the molecular scale to whole organisms and ecosystems, and hence biophysical research demonstrates significant overlaps with biochemistry, physiology, cell biology, nanotechnology, bioengineering, computational biology, systems biology, theoretical biology and so forth. The current activity of biophysics has evidently grown over the first idea in "biophysics", the term originally introduced in the 19th century. BSJ would like to cover the current trend and the future direction of this field with a term “physicobiology” .
