The Doomsday Clock is an internationally recognized design that conveys how close we are to destroying our civilization with dangerous technologies of our own making. First and foremost among these are nuclear weapons, but the dangers include climate-changing technologies, emerging... Read More
In a welcome but little-noticed development, the United States recently encouraged fellow members of the Biological Weapons Convention to take a deeper interest in “tacit knowledge,” a key determinant of bioweapons development, but one that nonproliferation efforts have largely ignored.
The US Energy Secretary takes a little time this week to provide Bulletin readers with a quick update on the administration's efforts to convince Congress and the American people to support the Iran nuclear agreement
A typhoon was coming, the fuel pump failed, they had to switch planes, things were wired incorrectly, they missed their rendezvous, they couldn’t see the primary target, they ran out of gas on the way home, and they had to crash-land. But the worst part was when the Fat Man atomic bomb started to arm itself mid-flight.
Over the last two years, the Bulletin of the Atomic Scientists and the University of Chicago have created an online tool that will help countries understand the true cost of choosing the reprocessing route—and perhaps help limit the spread of nuclear reprocessing. Here's how.

Today, more than 25 years after the end of the Cold War, the members of the Bulletin of the Atomic Scientists Science and Security Board have looked closely at the world situation and found it so threatening that the hands of the Doomsday Clock must once again be set at three minutes to midnight.
The nuclear weapons production and laboratory system created during the Cold War is simply far too large for the current military situation and needs drastic consolidation that includes the closing of labs and other facilities
The first installment of a five-part series exploring the diplomacy and intelligence efforts that led Libya and its quixotic leader, Muammar al-Qaddafi, to relinquish that country's weapons of mass destruction

For decades before it was selected for closure, the Treasure Island Naval Station in San Francisco Bay overhauled military ships and housed nuclear war academies that used radium, plutonium, and cesium 137 in their training courses. The Navy knew for years that those materials were not always in safe hands. But it did not acknowledge that history publicly, and as a result, workers preparing for civilian redevelopment may have inadvertently spread radioactive material around the island, The Center for Investigative Reporting (CIR) has found in a yearlong investigation co-published by the Bulletin of the Atomic Scientists.

A careful review of threats leads the Bulletin's Science and Security Board to conclude that the risk of civilization-threatening technological catastrophe remains high, and that the hands of the Doomsday Clock should therefore remain at five minutes to midnight.
