Response to Bulletin of the Atomic Scientists Article on Iran’s Short Timeline to a Bomb
Iran can build a crude nuclear weapon too quickly, in about six months, after a decision to do so, but the regime risks being detected early after its decision to do so and all along its subsequent pathway to a bomb. That time is more than sufficient for a devastating military response by Israel, hopefully supported by the United States and other allies.

FTC Rightfully Acts Against So-Called “AI Weapon Detection” Company Evolv
The Federal Trade Commission has entered a settlement with self-styled “weapon detection” company Evolv, to resolve the FTC’s claim that the company “knowingly” and repeatedly” engaged in “unlawful” acts of misleading claims about their technology.

Preparing our Ports for the Future of Alternative Maritime Fuels
Fuels like ammonia will greatly reduce carbon emissions—better for the environment, but are they safe for our infrastructure? The Science and Technology Directorate (S&T) recently conducted a market research survey to assess hazards associated with alternative fuel production, storage, and transport at U.S. ports. High-risk ports could be the sites for future ammonia release tests that will inform preparedness and response.

The History of WIPP
In 1975, the nation asked Sandia to investigate the possibility of building a repository in New Mexico for the disposal of radioactive transuranic defense waste. Little did those assigned to the project know that the task would absorb most of their careers and become one of the most controversial and important projects in U.S. history.

War Risks from Nuclear Power Plants? Just Look at Zaporizhzhia
As evidenced in an International Atomic Energy Agency (IAEA) report released in September, Russia’s occupation of the Zaporizhzhia Nuclear Power Plant in Ukraine continues to create high risk of a nuclear disaster. In considering future conflicts, no one can safely assume that an enemy will avoid targeting nuclear power stations.

We Need a New Discussion About Iran’s Nuclear Weapons Work
U.S. intelligence is shielding the Biden-Harris administration from having to take serious action on Iran’s nuclear program. While hinting at nuclear weapon activities taking place, the U.S. intelligence community is focusing on public Iranian statements and old news on Iran’s capabilities to produce weapon-grade uranium — but it avoids any type of public discussion on what nuclear weaponization activities Iran may be undertaking, and how soon it can build a nuclear weapon. Likely, because some uncomfortable truths would come out: Iran can do it way too quickly, and initial activities to build the bomb could be difficult to detect.
