Excellent analysis from Matt Bunn.

Note the danger he cites that Iran still has a supply of 60% enriched uranium and deeply buried centrifuges that could spin it to bomb grade. This strike may have accelerated Iran’s efforts to get a bomb. What would Israel or the US do? Attack it?

Israel and the US strike Iran. It is a tragedy of Tehran's own making Iran's strategy rested on the critical assumption that the US administration preferred a deal to a war. It proved fatal on Saturday.

Iran's strategy worked. Only up to a point, Nicole Grajewski (@nicolegrajewski.bsky.social) writes in @thebulletin.org.

The Elders urge USA, Russia to halt nuclear arms race as New START expires.

The world faces a destabilising nuclear arms race as the New Strategic Arms Reduction Treaty (New START) between the United States of America and the Russian Federation expires on 5 February.

ELDERS’ STATEMENT | The Elders urge USA, Russia to halt nuclear arms race as New START expires

Putin and Trump must act urgently to secure a new deal, reduce nuclear risks and protect humanity.

“The Doomsday Clock is a sign of leaders’ failure to act responsibly in the face of existential threats. “They have not heeded the warnings of previous years, so once again the hands of the clock have moved even closer to midnight.” Juan Manuel Santos Chair of The Elders

“The looming expiration of the New START treaty between Russia and the USA means nuclear risks are likely to get even higher. This is intolerable. Humanity deserves better. Global citizens need to mobilise and make their voices heard, so leaders feel real and urgent pressure to change course.” Juan Manuel Santos Chair of The Elders

The Doomsday Clock has moved four seconds closer to midnight.

This is the consequence of world leaders’ lack of attention to the nuclear threat.

"The Doomsday Clock's message cannot be clearer. Catastrophic risks are on the rise, cooperation is on the decline, and we are running out of time. Change is both necessary and possible, but the global community must demand swift action from their leaders." — Alexandra Bell Bulletin President and CEO

“National leaders … must take the lead in finding a path away from the brink,” writes the Science and Security Board in the 2026 Doomsday Clock statement.

“Citizens must insist they do so.”

It is like a knife in my heart when I see what these thugs are doing to decent and loving people. He was trying to help a woman who had been violently pushed to the ground. And paid for that with his life, murdered by violent and vicious criminals masquerading as law-enforcement.

Fallout maps show how an attack on nuclear silos would impact US cities USA TODAY mapped the far-reaching potential consequences of a nuclear strike against America's 450 nuclear missile silos.

I had a really fun time working on the code that was used to make these fallout visualizations for this USA Today article. I will soon be incorporating some of it into the NUKEMAP and probably making a version of this "mass attack fallout mapper" for public use. www.usatoday.com/graphics/int...

Eighty years and 89 seconds: It’s time to fight against midnight In the 80th year of the nuclear age, with just 89 seconds left on the Doomsday Clock, every nuclear challenge is trending in the wrong direction.

In less than a month, the US and Russia will have no legally binding measures constraining each other's strategic nuclear arsenals. 60 years of work to prevent nuclear war between Washington and Moscow is being effectively abandoned. My take on what to do next: thebulletin.org/premium/2025...

People have a right to know about global threats. That's why the Bulletin exists. But we need your help.

At the Bulletin, we believe everyone has a right to know about global threats—because they endanger us all.

At a time when disinformation spreads faster than truth, your support helps nonprofit newsrooms like the Bulletin deliver reporting the world depends on.

It’s the gold standard of US climate research. Contrarians could write the next one. Researchers who have downplayed the threat of global warming have been asked to author the next National Climate Assessment.

It is hard to overstate how wildly inappropriate it is to replace a National Climate Assessment--A process normally involving hundreds scientists, significant public and expert input, and US government-wide coordination--with five climate skeptics using AI.

Eighty years and 89 seconds: It’s time to fight against midnight "Eight decades since the Trinity Test and the first use of atomic weapons in war, we now find ourselves at an inflection point. The rising tide of nuclear challenges threatens to overtop what remains of our poorly tended metaphorical levees. The choices in the months and years ahead will determine our fate. The future—our future—is on the line."

In the 80th year of the nuclear age, with just 89 seconds left on the Doomsday Clock, every nuclear challenge is trending in the wrong direction, writes Bulletin president and CEO Alexandra Bell @atomicbell.bsky.social.

Exactly 80 years ago, scientists who helped build the world's first atomic bomb published a "bulletin."

That was the beginning of the Bulletin, our nonprofit newsroom.

To mark the anniversary—in true Bulletin fashion—we published a magazine that looks to the future: buff.ly/REJsWIF

When it all comes crashing down: The aftermath of the AI boom AI has buoyed the stock market and a struggling US economy but warning signs indicate a bubble that everyone will pay for when it bursts.

Silicon Valley has placed a trillion-dollar bet that gen AI can transform the global economy and pave the way for AGI. But warning signs show the marketing hype has vastly overrated what current AI tech can achieve, creating a bubble with growing costs when it pops, writes @jeremyhsu.bsky.social.
