Trump administration plans to break up largest federal climate research center Russ Vought, director of the White House Office of Management and Budget, said the National Science Foundation "will be breaking up" the National Center for Atmospheric Research in Colorado.

“NCAR has played a greater role in advancing weather prediction & atmospheric modeling than perhaps any other single entity in the world,” says @weatherwest.bsky.social

Dismantling NCAR would be “like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.” KH

The Trump regime wants to dismantle a world leading climate research center. Why? Because the US has become a petrostate where the government has been captured by fossil fuel interests.
They’re calling climate science “green new scam research”, in full denial of reality. 🤯

YouTube video by Sabine Hossenfelder The 2025 Physics Nobel Prize: Macroscopic Quantum Tunneling

The 2025 Physics Nobel Prize was awarded for macroscopic quantum tunneling. What is this and what is it good for? I have a brief summary.

The Royal Swedish Academy of Sciences has decided to award the 2025 #NobelPrize in Chemistry to Susumu Kitagawa, Richard Robson and Omar M. Yaghi “for the development of metal–organic frameworks.”

We are now part of the Global Ecology starter pack 3.

“Model-free“ analysis of a complex system. Part II Or: when you don't even see what your model is

Model-free is never free, at best is hidden.

Many methods are powerful, and most of them work very well. Within the basin of their assumptions. 🧪

From climate shifts to economic collapse, tipping points can change everything.
Prof. Chuixiang Yi and his team call for a clearer way to understand resilience — and help us see the warning signs before it’s too late www.gc.cuny.edu/news/rethink...

“Where is everybody?”

Over lunch, Enrico Fermi posed a question that still haunts astrophysics (and, let me say, #ComplexSystems): if life is common in the universe, why haven't we seen evidence of it?

The Drake Equation sets the stage for this paradox.

New study highlights the active role of humans in the hunter-farming transition. Varying population growth and mortality rates, driven by competition between hunter-gatherers and farmers, shaped agricultural development in these regions. @andrejpaleo.bsky.social www.pnas.org/doi/epub/10....

Exactly. What are those Republican congressmen and senators talking about behind closed doors? What are they telling their children? How do they see their future? How can they not wake up in the morning and find themselves transformed into a giant beetle?

Our perspective paper on resilience and tipping points is now out! We outline key principles to guide future research on these critical topics, from dynamical systems to real-world applications.

Why the long history of calculating pi will never be completed Building the full value of pi has been a project thousands of years in the making, but just how much of this infinite number do we actually need, asks our maths columnist Jacob Aron

I'm launching a new monthly maths column, and what better day to do it than Pi Day? Read on to learn what an ancient Egyptian scribe called "Directions for Knowing All Dark Things", why Newton was ashamed by pi, and how our best estimate was wrong for a century

🚨 Excited for the latest paper from the lab, led by Zhang & Arsham.

Can we coarse-grain a #ComplexNetwork while preserving macroscopic network flows?

Surprisingly, the answer is positive, and we have shown it by means of StatPhys + Machine Learning.
