While the community remains skeptical regarding the existence of effective attractions between like-charged species, recent computer molecular dynamics simulations have demonstrated not include solvent effects that play an important role for the structure of charged species in solution  . Specifically, the solvent plays a key role in the charge localization of the diffuse ions in ion-rich domains that bring charged species closer together. Based on this idea, simulations have explained experimental trends such as the disappearance of a scattering peak in salt-free polyelectrolyte solutions that PB and primitive model approaches fail to explain.
