New comment by beejiu in "Weightlifting beats running for blood sugar control, researchers find (2025)"

beejiu — Sat, 11 Jul 2026 23:57:53 +0000

"In this model, mice lived in specially designed cages where food was accessed through a hinged, weighted lid. To eat, the mice had to lift the lid while wearing a small shoulder collar, causing a squat-like movement that engaged the muscle contractions people use during resistance exercise. The load was gradually increased over several days, mimicking progressive strength training."

So the study doesn't really show that weighlifting per se is beneficial, but putting food behind weighted hatches is?

"Voluntary wheel running (EEX) was conducted as previously described in single-housed mice with access to voluntary running wheels and food and water ad-libitum,"

And the runners could each as much as they liked?

Sounds like bunk.

Yes, and just yesterday a passenger train was routed into the path of a freight train due to some points failure. It does make you wonder. https://www.railmagazine.com/news/points-failure-results-in-...

A bit part of education is (should be) independent learning with textbooks and reading. You don't need to be "tutored".

I'm probably going down a conspiracy theory, but it's notable when all the Five Eyes countries seem to start talking about the same problem and pushing through legislation. The US would probably do the same if not for the constitution.

Are your UUIDs generated client side or server side? If it's client side, it could be due to a crawling bot. Googlebot for example executes Javascript using deterministic "randomness".

In Europe, the max interchange fee is 0.3%. In the US, the average is 2%. So the relative impact of fraud is much higher.

If you're using R in 2026, you're probably invoking code compiled from Fortran from the 70s/80s somewhere along the line. It's a foundation for a lot of numerical computing.

The UK is consistently amongst the lowest household expenditure on food in the entire world. Only 3 countries in the world are self sufficient in food. If this "reasonable worst-case" scenario happens, surely the UK is one of the better placed to deal with it?

GB News gets a lot of criticism, but I watch the odd show and I've always found it to be balanced. There's a lot of political and regulatory pressure against them, so much so that GB News took Ofcom to the High Court and overturned illegal actions that Ofcom had taken.

I can only speak from a UK perspective, but all broadcast media here is regulated. So the things you might see in the US just can't happen and don't happen here. Everything has to be editorially balanced. Online media doesn't fall under the same regulations.

Because you can't get doomlooped into right-wing podcasts and "citizen journalism" on the TV.

Sample quotes from men in the study:

"Who tells me what's right and what's wrong... is it true or is it not true? Some of the things on YouTube are independent. I find I would listen to them more, because they're on the ground. They're telling you the story. "

"If you see something on social media, whether you believe it or not, you can go to the comments and see everyone's points… If most people agree with it, you know you should be at least somewhat agreeing with it. "

"It seems to everyone that it's an agenda, like the government's behind an agenda… it's like a brainwashing tool for the government. An illegal immigrant killed someone in the street the other day, stabbed them to death… And it's all over Facebook, all over YouTube. And the news hasn’t even said anything about it"

Only one man mentioned using YouTube for entertainment.
