Submission + - Amid K-12 AI Pushback, OpenAI Named Lead Partner of 'Hour of AI' for Kids

theodp writes: On the heels of announced AI moratoriums by the nation's two largest K-12 school districts (NYC, LA), tech-backed nonprofit CodeAI (aka Code.org) this week named OpenAI 'Lead Partner' for the 2026 Hour of AI, which has replaced the Hour of Code (RIP, 2013-2024) as the premier event for the nation's K-12 schoolchildren during December's CS Education Week. OpenAI investor and partner Microsoft was named as one of two 'Supporters' for the event/infomercial (the other being U.S. defense contractor Northrop Grumman).

In August, as it launched ChatGPT for Teens, OpenAI announced a new signature partnership with Code.org to 'prepare the first AI generation', explaining that 'through the Hour of AI, OpenAI and CodeAI will introduce millions of students to the basics of using AI thoughtfully and responsibly.' OpenAI and Microsoft last year teamed up with the American Federation of Teachers to 'bring AI into the classroom', but that honeymoon is over. For more on the inside story of how Big Tech is applying the same playbook it used to scale coding lessons nationwide to now mainstream their AI tools in schools, check out Coding Kids: Big Tech's Battle to Remake Public Schools.

So, much like the Hour of Code that preceded it, will the Hour of AI serve as tech's 'Trojan Horse' (ChatGPT-generated parody cover) in its 'Odyssey' to push its agenda and curriculum into schools?

Polar circle?
Oh you mean the Arctic Circle.
Hardly ...

I live at latitude 43.44 N.

That is south of Florence Italy, and Nice and Cannes, France.
Also south of Madison, Wisconsin, and Minneapolis Minnesota.

And the most populous places in Canada are nearby.

But yeah, to Americans, we are "up north", so we have to be in the Arctic Circle.

Yeah, it's not a good study. If nothing else (and there is much else) the sample size is too small.

OTOH, I find it difficult to understand why so many people seem to think it's "obviously wrong", when I would have predicted that result from a good study. People tend to be unreasonably biased, and not just about sex. There've been studies where two groups of people were divided at random. Those who ended up in each group tended to prefer their group over the other, even though the group didn't exist outside of the study. (I say that, but I don't know for sure that the folks didn't maintain their groups after the study was over...but it was a pretty short study.)

That's a difference, it's just not a significant difference. It might well justify a larger study with more careful controls. But the result they produced is what I would have guessed, so I'm a bit biased.

Still, look at any sports team match. People tend to favor one side over the other for reasons that have nothing to do with skill.

I'm sure that's happening. I'm also sure it's only a part of the story. Some of the other posts have raised other contributory issues, like image quality. And actually I think your point is a valid example of a more general trend, i.e. people tend to favor those who are more socially approved. The reasons for the social approval are nearly irrelevant, but different groups within society will use different measures. (E.g. Catholics will tend to approve of different people than Unitarians, even if they adopt the same proposals.) Think of how some people rate their favorites sports team vs. the way they rate the other side.

The study *is* flawed. The sample size is too small, and I doubt that the people tested replicate the world population average.

But it *is* "food for thought", and the result is the one I would have expected. People *do* tend to be biased in favor of the socially more approved of groups. (You don't need a study to prove that. Just read either the news or history, especially the history of a conflict.)

Submission + - First Nuclear Clocks Start Ticking in Vienna and Beijing (phys.org)

necro81 writes: Two groups, one in Vienna and one in Beijing, have successfully demonstrated the world's first nuclear clocks. Standard atomic clocks, like the caesium clocks that define the second, operate by observing the transition of electrons between different orbits about the nucleus. The resulting radiation is usually in the microwave range, and can produce clocks accurate to one second in 100 billion years.

Nuclear clocks go a step further, and probe energy transitions within the nucleus itself. Nuclei can arrange their protons and neutrons into different configurations, called isomers. The isomer with the lowest energy is the one usually found; higher-energy ones are only metastable and decay quickly. Usually it takes serious energy — x-rays and gamma rays — to excite a nucleus into a higher-energy arrangement. It so happens that thorium-229 can be excited using UV light with a wavelength of 148 nm — just within the capabilities of some exotic lasers.

It's still been quite a challenge. For one thing, Th-229 is not found in nature; it must be extracted from the decay chain of uranium-235. The Beijing team used just a microgram mixed in a crystal of calcium fluoride.

Although these prototype nuclear clocks are not yet more accurate than existing atomic clocks (one second in millions, rather than billions, of years), they show the way towards what may be possible. Because the energy transition is in the nucleus, rather than the electron cloud, it is less susceptible to outside disturbances like magnetic fields. And the fundamental frequency is much higher (five orders of magnitude), which should yield more precise timing. This development could lead to smaller and more reliable time standards across the world (and solar system).
