Not tested, but try something like this:

using (var db = new YourDataContext())
{
   var results = from n in db.News 
                 let v = db.News
                 where n.NewsId == v.Where(c=>c.CategoryId == n.CategoryId)
                    .OrderByDescending(o=>o.CreatedOn).First()
                 select n;
}
