"It is ridiculous, it is embarrassing". Sen. Mark Kelly rips Pete Hegseth, noting he's in the National Command Authority for nuclear weapons, yet he's posting "turtles with rocket-propelled grenades". Kelly says he should be fired.

in addition to viruses taking us to school, we're also on track to have the climate events doing the education

Offit told me that Kennedy is a "liar" and a
"terrible human being." I asked him to explain. "It doesn't matter what I say," Offit said. "He thinks the medical journals are in the pocket of the industry, he thinks that the government is in the pocket of the industry, he thinks I'm in the pocket of industry, and he's wrong." Offit continued: "If he has data showing he's right, then fucking publish it. He can't, because he doesn't have those data."
I asked Offit if he saw a way to reverse the public's rising distrust in science. "I don't think there is any way to regain that trust other than have the viruses do the education, and the bacteria do the education, and then people will realize they paid way too high a cost," he said.

This is a staggering cool JWST image of one of the most terrifying star systems I have ever seen. Apep is a monster… *three* monsters, actually, and blasting out radiation and dust and junk at speeds to freeze the soul.

Read all about it!

A ridiculously jaw-dropping JWST image of a fantastically terrifying star system

Apep consists of three immense and immensely powerful stars blasting out a fierce dusty wind

I'm not really an F1 fan, but I'm surprised at how much strategy there is. I used to think the only strategy was "drive fast" but decisions on which tire to use and how to go into pit stops turn out to be decisive when the cars are so evenly matched.

Yeah, the comments are a trip. I seriously think that people believe AI weather forecasting is people going to ChatGPT and typing in “what’s the weather going to be tomorrow?”

This is a legitimate scientific revolution in meteorology.

Also, to be clear, these models are not the AI LLMs that most people are familiar with. They are machine learning algorithms trained on observations (actually reanalysis).

Meteorologists are surprised that the weather model that did the best job forecasting hurricanes this year was a new one, introduced by Google. AI may be the beginning of a new era of forecasting. n.pr/49MFa1M
