In a Communication in the April 9, 2008 edition of the Journal of the American Chemical Society, Prof. Doug Tobias and collaborators in Europe report a study of the dynamics of protein molecules and their hydration shells using a combination of neutron scattering experiments with selective deuteration and molecular dynamics simulations. The results firmly establish and explain, for the first time, the direct coupling between soluble protein and water dynamics suggested by many previous experimental and theoretical investigations.
