Here are some instructions to show you how to create an RSS news feed on any search string. It is pretty simple to do and great if you have special interests, but no good portal site to do the combining for you.
Simply copy this string:
http://news.google.com/news?q=global%20peace&output=rss
and replace the global%20peace with the search stirng of your choice. For every space add %20
You can see mine in the menu to the right (well you could in October 2006)
Thats it. You can go home now.
If you wanted it on your site in WordPress your theme would have to be able to display Sidebar Widgets so that you can add an RSS box.
