To Explain Simply Physics on Nuclear Criticality

From physics to biology by extending criticality and symmetry breakings.

Symmetries play a major role in physics, in particular since the work by E. Noether and H. Weyl in the first half of last century. Herein, we briefly review their role by recalling how symmetry changes allow to conceptually move from classical to relativistic and quantum physics. We then introduce our ongoing theoretical analysis in biology and show that symmetries play a radically different ro...

HIV-1 Virology: Simply MArvelous nuclear transport

HIV-1 MA protein is a viral membrane protein, but it is also involved in nuclear import of the preinitiation complex; the latter requires transfer of some MA molecules to the maturing core particle during virus assembly.

Nuclear Physics

the first importance. Behnke has demonstrated that the "lean body mass," since it represents the active tissue of a person, is superior to reference standards hitherto proposed for the estimation of physiological functions such as the masses of various organs and tissues and the volumes of the different fluid compartments in the body. In the present article, which has been reprinted as a short ...
