Loop through them and use the DOM functions:

var news = document.getElementsByClassName("news-story")[0];
var items = json.items;
for(var i = 0; i < items.length; i++) {
    var h5 = document.createElement("h5");
    h5.innerHTML = items[i].title;
    news.appendChild(h5);
    var p = document.createElement("p");
    p.innerHTML = items[i].author;
    news.appendChild(p);

}

getElementsByClassName will not work in versions of IE prior to 9. If you need to support those though, you’re really better off using jQuery.
