Under pressure from the Trump administration, the National Science Foundation (NSF), a $9 billion agency funding scientific research that has made America great, has canceled over a thousand grants and slowed new funding. That's just the beginning and will get way worse unless Congress intervenes.
Amid DOGE-induced turmoil, National Science Foundation in crisis
The $9 billion agency, which exists solely to fund researchers, projects and facilities outside its Alexandria, Virginia, headquarters, is hitting reverse on its mission.

One of a meteorologist’s biggest pet peeves is “my app says it’ll be ____”. Weather apps can miss so many details that a meteorologist will know.
Let’s use tomorrow in NYC — my app says it’ll be 78 degrees but rainy. But is that the full story? Spoiler alert… no, it’s not!

As someone who has reported on AI for 7 years and covered China tech as well, I think the biggest lesson to be drawn from DeepSeek is the huge cracks it illustrates with the current dominant paradigm of AI development. A long thread. 1/

It is high time to meditate on the effect that North American conditions can have on Europe (and not only from a meteorological viewpoint!)
In the current event, I like how it is the same trough now above the southern US that moves over the Atlantic to support the strong Atlantic cyclogenesis 🌀

The fires ravaging the outskirts of Los Angeles are driven by anomalously strong easterly winds, locally known as 'Santa Ana winds".
Low-level winds speeds over the area exceed 5 standard deviations in anomaly (though wind speed is not gaussian, but ok).
But why are they so strong?
