Research at Univ of Arizona... They've come up with a way to more accurately measure van der Waals forces... specifically the force between an atom and a surface, which may have some bearing on LENR. Here is the interesting bit... "The most significant discovery was that an atom's inner electrons, orbiting the nucleus at a closer range than the atom's outer electrons, influence the way the atom interacts with the surface. 'We show that these core electrons contribute to the atom-surface potential,' Lonij said, 'which was only known in theory until now. This is the first experimental demonstration that core electrons affect atom-surface potentials.' "
