Why the racial gap in life expectancy is declining in the United States
BACKGROUND Blacks have lower life expectancy than whites in the United States.

In the case of protein biosynthesis the notion of the physical aspect of the process can be qualitatively enriched by taking into account the symmetry of conformational oscillations. This is the key to understand the selectivity in biochemis...
