The Doomsday Clock is Ticking on Biosecurity

Last Tuesday, we and the other members of the Bulletin of the Atomic Scientists’ Science and Security Board moved the iconic Doomsday Clock to 90 seconds to midnight, the closest it has ever been. We moved it largely (though not exclusively) because of the mounting dangers, both direct and indirect, of the war in Ukraine. (See the accompanying statement we published alongside the time change.)
