Worried that the LHC experiment will destroy the world? Fikar not… this is the era of citizen journalism, user-generated content and continuous updates… here are a couple of links to keep the paranoid you reassured 
http://HasTheLargeHadronColliderDestroyedTheWorldYet.com/ (Atom feed)
http://HasTheLHCDestroyedTheEarth.com/ (RSS feed)
And for the geeks out there go check the source markup for those 2 pages 
Here is a snippet from the first link:
<body> <div id="main"> <script type="text/javascript"> if (!(typeof worldHasEnded == "undefined")) { document.write("YUP."); } else { document.write("NOPE."); } </script> <noscript>NOPE.</noscript> </div> <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); </script> <script type="text/javascript"> var pageTracker = _gat._getTracker("UA-275043-3"); pageTracker._trackPageview(); </script> <!-- if the lhc actually destroys the earth & this page isn't yet updated please email mike@frantic.org to receive a full refund --> </body>
