... but be careful what you grab and display on your page. In many cases, material may be copywrited, and you'll most likely need permission to use it. You may also be required to note where you got the information from.
If you are truly interested in grabbing information from Yahoo, you may want to read this. In an nutshell, they explicitly deny permission to reuse any of their news articles, but they do give you a list of their sources so that you can contact them. In most cases, I think you'll find that they expect to be paid.
Good Luck!
