It's time to set our watches again. The Doomsday Clock moved two minutes closer to midnight this week. This is of course just a symbolic clock that's wound every now and then by board members of the Bulletin of Atomic Scientists. In 1947 the BAS started using the clock to measure how close we are to global nuclear annihilation. The closer the minute hand gets to midnight, the more doomed we are. And as of Wednesday, it's 11:55. We asked Weekend America's Sean Cole to look into how doomed we are and if there's anyone who might be able to offer a second opinion.
