AI billionaire-funded Super PACs will spend millions in the home stretch of the midterms to crush the anti-data center revolt in battleground states.

And that's just a drop in the bucket compared to how much these oligarchs would rake in from the AI takeover.

So far the war in Iran has cost an estimated $5.5 billion.

That's roughly $1 billion per day.

$41,666,667 per hour.

$11,574 per second.

People do not want this.

They want a living wage. They want healthcare. They want to be able to afford a home. They want their basic needs met.

🚨BREAKING: Minnesota state attorneys alleged in a court hearing that Donald Trump and the Department of Justice are attempting to force the state to surrender its sovereignty — in particular, its control over elections — through the massive federal immigration operation in the Twin Cities region.

Across America and the world, people are realizing it’s not possible to appease America’s dictator.

The only way to deal with him is to stand up to him — and the only way to stand up to him is by joining together against him.

It's time for a massive general strike across the country.

The first time Charlie Chaplin spoke onscreen, he implored the people of the world to resist the rising tide of fascism.

Nearly 90 years later, it remains a timely message.

The GOP governors of South Carolina, Louisiana, Mississippi, and Tennessee have all sent their states' National Guard troops to assist Trump's occupation of DC.

All four of those states have cities with crime rates higher than DC.

This was never about "fighting crime."

If you’re going to use an example to help explain a concept, it may not be to your advantage to make the example more complicated than the concept itself

If a trial is powered for blood pressure as a primary outcome, take care when drawing conclusions about noisier secondary outcomes, such as time-to-dialysis.

Hello everyone! I just finished writing a piece on large language models and medical decision making.

I argue that one who sets out to build a chatbot that solves medical problems will ultimately find themselves staring into the cold, hard eyes of evidence-based medicine.

When bullshiters tell you they will soon be able to make "digital twins" of patients, remember articles like this about how hard it is to model a single cell.
Ewen Callaway reports on biology's rush for AI-enabled 'virtual cells'.

So far it "has a lot of hype, but not a lot of concrete results or a clear path to success".

"I don’t think there is a clear definition of a virtual cell", says CZI's Jonah Cool.

Like this idea that research question should precede regression. Especially in the medical field, patient should always come before model
