  • The Idaho researchers observed that reversing the intrinsic angular momentum, or “spin,” of thorium-229’s outermost neutron seemed to take 10,000 times less energy than a typical nuclear excitation. The neutron’s altered spin slightly changes both the electromagnetic and strong forces, but those changes happen to cancel each other out almost exactly. Consequently, the excited nuclear state barely differs from the ground state. Lots of nuclei have similar spin transitions, but only in thorium-229 is this cancellation so nearly perfect.

    Basically, thorium-229 can be excited by conventional lasers instead of gamma rays. Instead of millions of electron volts, it takes less than 10, which means it’s more reliable and more precise.









  • Apples AI is mostly processed on device. That’s why it takes an iPhone 15 pro or an M-series processor. They also claim that what is processed in the cloud is neither identifiable nor stored, just processed. We will know if that’s true (at least what is being sent) as soon as it gets out into the public and we can start picking apart the traffic.

    There is no mention of opt-out or not yet, probably because we’re several months away from the actual release. I’m sure we’ll get more information before then.
