US President Donald Trump has an opportunity to avoid the dangers of an unrestrained nuclear arms competition, writes @matthew-bunn.bsky.social. It's an opportunity opened by Russian President Vladimir Putin. ⬇️

Trump to the UN: "I'm really good at this stuff. Your countries are going to hell."

Join me this Thursday for a virtual panel on the state of play on US scientific research, along with Obama Administration Science Advisor John Holdren and @thebulletin.org President and CEO Alex Bell.

Today, the teaser trailer for "A House of Dynamite" was released, joining a long history of motion pictures exploring the danger of nuclear weapons. Here's a collection of Bulletin coverage to get you started, from "Dune" to "Oppenheimer," to "Godzilla" and "The Day After." ⬇️

We've launched our first-ever short fiction contest. Entries can be of any genre, as long as they have some connection to (avoiding) the apocalypse. The first-place winner will receive $3k, with $500 each to four runners-up. The deadline for submissions is Sept 30. thebulletin.org/write-before...

On Monday, August 18 at 11:30 AM CDT, the Bulletin will bring together a group of leading experts to discuss the outcomes of the Trump-Putin Summit. Register for free below.

Eighty years of avoiding nuclear use and here we are - watching US & Russian leaders randomly trading nuclear threats on social media. It's beyond ridiculous - it's unconscionable. It's time for them to put down their phones and get back to talks on nuclear stability. www.reuters.com/world/trump-...

This is a new one. In order to hide the cost of Trump’s bribe from Qatar, the DoD has moved $934 million from the new ICBM program to pay for the plane’s renovations. The cost of our nuclear arsenal is so huge, that they thought no one would notice. www.nytimes.com/2025/07/27/u...

Last week, the Nobel Laureate Assembly for the Prevention of Nuclear War ended with a performance by Kronos Quartet alongside singer-songwriter Allison Russell. You can watch their performance of Bob Dylan's "A Hard Rain's A-Gonna Fall" below.

Tomorrow marks the 80th anniversary of the Trinity nuclear test and the dawn of the nuclear age. Discussions on how to manage nuclear risks in the years ahead are well underway at the first-ever meeting of Nobel Laureates and nuclear weapons policy experts.

“They cut key experts on nuclear testing, nuclear verification and efforts to end the production of weapons grade fissile material. These cuts will only serve to increase the nuclear threats facing this nation.” www.washingtonpost.com/politics/202...

Tom Countryman at State Dept Rally right now: I cannot imagine any of the 9 Secretaries of State that I served would have accepted this decapitation, this decimation of their department with such docile obedience as Secretary Rubio.

Senator Van Hollen right now at the State Department: These firings represent America in retreat. A retreat from our principles and values.

Rubio just fired every expert at State working on multilateral nuclear arms control. Do you feel safer?

I'm hearing rumors that Secretary Rubio had RIF'ed the person who serves as the National Authority to the OPCW. Rubio has said the destruction of Syrian chemical stockpiles is a priority for him. Firing the person who leads that effort would be incompetence of the highest level.

Nuclear war, AI, climate change, and disinformation are just some of the factors moving the hands of the Doomsday Clock closer to midnight. Daniel Holz from the @thebulletin.org‬ says we urgently need to help move them back. The latest from our friends @revealnews.org: tinyurl.com/49hbxpw9

Pretty astonishing to see Secretary Rubio bragging about how he'll get to fire thousands of hard-working patriots at a time where the need for diplomats could not be more apparent.

Three former chairs of the United States Nuclear Regulatory Commission explain how Trump's executive orders could have unintended safety consequences. "Why the US must protect the independence of its nuclear regulator," by Stephen Burns, Allison Macfarlane, and Richard Meserve.

Leading up to the Bulletin's 80th year of publication, we're launching a short fiction contest, "Write Before Midnight." It will be judged by acclaimed science fiction author Kim Stanley Robinson. Deadline for submissions is September 30, and the first-place winner will receive $3,000. More below.

‼️ New news on the "One Big Beautiful Bill." It will add $3.3 trillion to the national debt over 10 years, according to CBO. This doesn't include debt service payments, which will add at least another half trillion. For context, the House bill *with* interest payments was $3.3 trillion.

Why am I so unimpressed by these strikes? Israel and the US have failed to target significant elements of Iran's nuclear materials and production infrastructure. RISING LION and MIDNIGHT HAMMER are tactically brilliant, but may turn out to be strategic failures. 🧵 1/17

Yesterday the United States bombed three Iranian nuclear sites. A review of what we know so far and how the world reacted: thebulletin.org/2025/06/unit...

On Saturday, President Donald Trump announced that the U.S. carried out strikes against Iranian nuclear sites. Yesterday, Bulletin nuclear affairs editor François Diaz-Maurin assessed the risks associated with such attacks. thebulletin.org/2025/06/the-...

If you're in the DC area, please join me at the @carnegieendowment.org on May 22 for an event launching my new book, 'THE NEW NUCLEAR AGE: AT THE PRECIPICE OF ARMAGEDDON' (with @coreyah.bsky.social, @atomicbell.bsky.social, and @davidehoffman.bsky.social): carnegieendowment.org/events/2025/...

Immediately after Donald Trump's inauguration, his administration began purging environmental security reports from the public record. "Running blind: The silencing and censoring of environmental threats to US national security," by @petergleick.bsky.social.

Today begins the third session of the Preparatory Committee for the 2026 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (or #NPT #PrepCom). Ahead of the meeting, @meckdevil.bsky.social interviewed Ambassador Harold Agyeman, this year's chair.

"There’s an important battle brewing over university overhead rates. Sounds boring, right? But hang with me and you’ll see why this is so crucially important to America. It will determine whether breakthrough technologies emerge in American labs or Chinese ones." thebulletin.org/2025/04/make...

The Doomsday Clock is closer too midnight than it's ever been, which is not awesome. But what does this metaphorical clock even indicate? omny.fm/shows/stuff-...

The current level of CO2 in the atmosphere is 427 parts per million. What does that mean, and what can we do about it? On April 17, join the Bulletin for a virtual event on the risks of climate change and how to understand what planetary shifts are inevitable—and which have solutions.

Elon Musk's quest to colonize Mars could upend international cooperation and the establishment of space as a commons—a risk to Earthlings everywhere. An illustrated essay by @weinersmith.bsky.social and @zachweinersmith.bsky.social, based on their Hugo Award-winning book, "A City on Mars."

What's next for efforts to reauthorize the Radiation Exposure Compensation Act? John Mecklin @meckdevil.bsky.social interviewed New Mexico Sen. Ben Ray Luján @lujan.senate.gov about RECA, which aims to support those impacted by US nuclear weapons tests, uranium mining, and nuclear waste leaks.

"There’s no reason for us to be building brand new nuclear weapons, we already have so many. You could destroy the world 50 times over, 100 times over...We’re all spending a lot of money that we could be spending on other things that are actually, hopefully much more productive.”

Alexandra Bell @atomicbell.bsky.social, a nuclear policy expert with experience in government and nonprofits, became the Bulletin’s president and CEO today. Bulletin editor-in-chief John Mecklin @meckdevil.bsky.social interviewed Bell on her plans for the Bulletin and a host of related subjects.

The 2025 #DoomsdayClock announcement is today at 10:00am EST / 1500 GMT. Watch the livestream on YouTube, Facebook, TikTok, or our website: bit.ly/411huC5
