ajax newsfeed with animation

I need a 'newsfeed' type animated table that will refresh every 1sec to check for results from .php file the PHP output right now is custom but I can change it to XML or JSON format is something like : <TIME> 03/21/2012 15:32:49 UTC <TEXT> This is a Test Headline This is a Test Headline Everytime a new entry is found the html table should show new headline with animation like a Twitter Feed where it 'fades in' at the bottom of the table. please include a gif or video animation of your solution.
