satisfying the requirements of the Nuclear Non-Proliferation Treaty without physical testing.
This confuses the NPT with the CTBT. The shift to simulation-based stewardship followed the U.S. end of explosive testing and the CTBT-era test-ban framework, not an NPT testing requirement.
Full reasoning
The claim mixes up two different treaties.
LLNL's Advanced Simulation and Computing program says the U.S. ceased nuclear explosive testing in 1992 and that ASC was established as stockpile confidence shifted from test-based to simulation-based stewardship in the context of a Comprehensive Nuclear-Test-Ban Treaty (CTBT). Separately, the UN Office for Disarmament Affairs describes the NPT as a treaty to prevent the spread of nuclear weapons, promote peaceful nuclear cooperation, and further disarmament.
So the article is wrong to say these simulations satisfied a requirement of the Nuclear Non-Proliferation Treaty. The no-testing issue is tied to the CTBT/test-ban framework, not to the NPT.

and the same team later simulated the entirety of a rat's brain.
This overstates what Blue Brain achieved. The project reported simulations of parts or fragments of rat brain tissue, while its whole-brain milestone was for the mouse brain, not the rat brain.
Full reasoning
The article says the team later simulated the entirety of a rat's brain, but the project’s own materials say otherwise.
EPFL's Blue Brain Project states that its aim was to build detailed digital reconstructions and simulations of the mouse brain, and its 2024 "mission accomplished" page says it enabled reconstruction of model mouse brains and parts of rat and human brains. Nature's 2015 coverage of a major Blue Brain result likewise described a "Fragment of rat brain simulated in supercomputer", not a full rat brain.
So the article overstates the achievement: Blue Brain simulated parts of rat brain tissue, while the whole-brain reference model described by the project was for the mouse brain.
