I'm not sure what they're using, but you can achieve the same thing with XHR (also called AJAX (which is a stupid term that should go away)).

 

The simple idea is to use JavaScript to have the user's browser poll the site asking if there are any updates.  If there are, you bring them in and update the HTML with DOM API.

 

The fancier version is to install an ActiveX or Java applet on the user's machine and the server pushes the updates to the clients; this way you don't have to have clients constantly polling the crap out of your site.

Learning how to pick keywords out of text will serve you well in the future.  But I'll help you!
