The nuclear weapons ban treaty’s entry into force is a significant step to reduce the threat of nuclear disaster. It should be recognized as such when the Science and Security Board of the Bulletin of the Atomic Scientists sets the time of the 2021 Doomsday Clock.

A new study found that about 75 percent of coal production is more expensive than renewables. Could coal—finally—be facing the exit door?

The leaders of North and South Korea met again this week, ostensibly with a goal of moving the peninsula they share towards denuclearization. Unfortunately they don’t seem to have done so, says Bulletin columnist Duyeon Kim, who followed the summit from Seoul. She shared her analysis with CNN.

Today, private citizens often know more about cyber threats than governments—and will happily sell their zero-day vulnerabilities to the highest bidder. This opens the remarkable possibility that defenders may be able to “drain the swamp” by buying up cyber threats on the open market.

Last month, I profiled President Barack Obama's record on nuclear threat reduction during his first term. I concluded that, while the president has taken impressive initial steps to reduce nuclear stockpiles, secure vulnerable nuclear materials, and retard the spread of nuclear weapons, key elements of his ambitious agenda remain unfinished.

At long last, the United States and Russia are on the verge of signing a new treaty that reduces the countries' nuclear arsenals. The treaty, a follow-on to the landmark 1991 Strategic Arms Reduction Treaty (START), has been 95 percent complete for months, at least according to many U.S. and Russian officials, but disagreements over missile defense and verification procedures delayed the process.
