Utilities, the nuclear industry, the US government, and environmental groups all have an interest in finding a permanent solution to nuclear waste. Here’s why they’re dragging their feet.

The EPA will likely weaken Obama-era fuel efficiency standards. California doesn’t have to care.

Climate change is still treated as an ecological and humanitarian issue. Recognizing its security dimension allows the armed forces to jump-start climate action.

Past arms control efforts failed to recognize the historical context in which new nuclear weapons capabilities were introduced. A new tool seeks to address that.

The striking realignment of alliances and priorities in the Middle East and beyond could impact Iran’s nuclear decisions.

A crash Defense Department program designed to deliver AI technologies to a combat theater within six months is a smashing success so far. But is the Pentagon ready for the enormous challenges that lie at the intersection of military power and artificial intelligence?

A recent congressional hearing tried to relive the fantasy that the US government could somehow manage to build a nuclear waste repository at Yucca Mountain. It doesn’t have to.

Renowned graphic designer Michael Bierut created much of the Bulletin’s current visual look and feel.

A woman’s son broke his leg and had an X-ray. Three weeks later, she was still so afraid of radiation that she would not hug him.

In a story that migrated off the New York Times’ home page far too quickly, David Sanger and William Broad asked a searingly important question that has yet to seize the world imagination: Can Saudi Arabian leaders be trusted with the means to create nuclear weapons?

The 2020 presidential candidate spells out a climate policy that pays serious attention to race, income, and class.
