Hmm. That's the feed I saw it with. We fetch hourly, and between the 
2:45pm and 3:45pm fetch, the urls didn't change. They did change from 
our initial fetch at around 2:10pm (when the first user subscribed) and 
the normal 2:45pm fetch. Maybe it was a one-time thing. Here's a sample 
just for kicks:

What we got around 2:10pm or so:
http://us.rd.yahoo.com/dailynews/rss/716/1b61ffe3d3e401f8a236c4e4727dcd70/*http://story.news.yahoo.com/news?tmpl
=story2&u=/ap/20030826/ap_on_sc/shuttle_investigation

What we got at 2:45pm:
http://us.rd.yahoo.com/dailynews/rss/716/56c2218fb25259b13bf8066330154de1/*http://story.news.yahoo.com/news?t
mpl=story2&u=/ap/20030826/ap_on_sc/shuttle_investigation

Again, we didn't see it between the last two fetches. Perhaps it was a 
fluke.

Use the guid as an index into the database for the item. But that 
doesn't tell you if the item's been edited. So you have new items, and 
updated items.
