I never tried Go but I'll give it a shot:

k := datastore.NewKey(c, "Activity", "", id, nil)
q := datastore.NewQuery("Article").Filter("__key__ =", k)

Where c is your appengine.Context

What about these solution, these way you dont need a query, neither an iterator is more direct way of solving the problem.

var article Article
k := datastore.NewKey(c, "Article", "", usrr.User, nil)
q := datastore.Get(c,k,&article)

What did you think?
