The title of the study is "Decreased nitrosylation of CaMKII causes aging-associated impairments in memory and synaptic plasticity in mice" - that would have been the base of the shortened title, if the study had been submitted. The dissemination article was chosen for submission because it was the one from the source University. (There are more around.) Further from using clear, synthetic expressions, it contains more information than just the (available abstract of the) research article - it is where an author of the latter states that next steps are pharmacological and involving humans.
