The #core of the #Earth spins around a slightly different axis compared to the #mantle. In this animation we start in a space frame and switch gradually to the frame spinning with the mantle. In that frame the core appears to wobble. The mantle precesses and the core, being fluid, lags a bit. 🧪 🔭

1/ There’s an instructive debate underway in the open review pages of @egu.eu journal Ocean Science. It’s about whether we can tell if the #AMOC is already on a trajectory towards collapse. What I think it really teaches is how scientists judge evidence, & why that differs from assessing risk. 🧵

What’s the most unsettling book you’ve read? I answered this question along with several others for Nautilus Magazine.

I don't care how famous you are in your field and how much grant money you bring in, how you treat your group members tells a lot about you. Over the years I have seen/heard of toxic behaviors from many PIs and they have lost my respect. ⚛️🧪

@tdietterich.bsky.social How will arXiv handle this? The author is explicitly claiming weaker responsibility than that required for submission. info.arxiv.org/help/moderat...

Someone please explain to me how could the "author" of this preprint "take responsibility for submitting this paper and for the accuracy of this statement" when he clearly states he has no training in astronomy, and cannot verify the results, meaning that he doesn't fully understand his own paper?

New paper led by PhD student Mariana Sastre (@marianasastre.bsky.social): "Thermal Evolution of Lava Planets Across System Ages: Predictions for Hell of a Survey", now accepted in The Astrophysical Journal 🌋 https://arxiv.org/abs/2609.20155 (1/6)

Colonisation mindset: destroy all other cultures

Absolutely worth reading.

A wonderful time this week at the Solid Earth Doctoral School in Les Houches at the foot of Mont Blanc to teach about seismic imaging of the deep Earth to PhD and MSc students from across Europe. deepearthschool.github.io

This was such a great answer from Abdul El-Sayed about his previous criticisms of President Obama.

My guy. Happy 56th birthday, dude!

Grover hive, today we ride

Happy birthday wishes to Grover Monster. "A 1970 appearance on The Ed Sullivan Show marked the first use of Grover's current design with blue fur and a pink nose.

To the first, I say: Fine, I don't want to go where that bandwagon is headed. "Left behind" is an interesting phrase, it indexes a notion of a race towards a desirable/shining "future" that only some can access, and which we should all hope to participate in. >>

Well, will you look at that

you mean an a(wk)ward.

This is incredible, amazing!!! 👏🤩🎉 Francis is a fan-tas-tic physicist, and an amazing person! And Belgian 😉

Exactly this. And in fact, many models *have* been created this way, and decades of prior machine learning systems *were* created this way, consensually. These things are choices! People are STILL working this way! It’s not just that a better world is possible — it already EXISTS. We can nurture it.

I am engaging more with Bluesky. What the hell is wrong with me that I still hold an account on a platform that serves as a forum to stroke a billionaire, mental toddler's ketamine fueled ego? When an ai leans towards coddling bigotry, it's very real and not intelligent. PLEASE FOLLOW

I can't stop thinking how wrong the tech bros have understood creativity and creators. Or even just having hobbies. #erliart

I'd never seen this Roy Lichtenstein painting before, but it's incredible how he manages unfailingly to make his copies worse than the original comics he's ripping off.

Yes every woman has been harassed, many assaulted. But every woman has also experienced invisible loss from moments she avoided harassment. She felt a space becoming unsafe, so she left, while men stayed on. And in leaving, she lost: opportunities, experiences, learning, promotions, even simply fun.

La #IA de #Claude parece que no ha identificado un nuevo sistema #CRISPR como nos contaron. Es muy probable que se haya nutrido de datos de un investigador de la Universidad de Copenhague que compartió durante años. Lo cuenta @aberron.bsky.social en @eldiario.es ⬇️ www.eldiario.es/sociedad/bio...

This is the most remarkable story Ray Bradbury ever shared with me. He told it to me late one night, sitting in his den of antiquities and mementos. Take five minutes to read this. It’s pure magic. #Writing #Living #Creativity #RayBradbury #BookSky

Seems depressingly relevant again

I’m sorry but if there is no Kermit what stops me from murdering people? A genuine internal desire to not harm others? Uh keep dreaming aphibiests

The techbros don't want you to see this trailer. Pass it on.

bumped into an incredible website gavin-theobald.uk/HTML/Pentagr...

I just find it kind of baffling how many people seem to forget that they were managing to do their jobs and live and accomplish things just fine three years ago or whatever when they couldn't ask the chatbot to do those things for them

this is just to say i have eaten the moon that was in my orbit and which you were probably wanting to observe forgive me it was delicious so crunchy and so cold

I said I'd do a thread about my new Space Science Reviews paper, so here it is! This is part of a collection of papers arising from a meeting at the International Space Science Institute in Bern in 2024: a workshop to better understand rocky extrasolar planets. A 🧵:

Potassium and sodium are significant sources of electrons in hot Jupiter atmospheres, and thus they play an important role in the atmospheric coupling to the magnetic field, among other things. I have a paper out that looks that their thermochemical kinetics. #exoplanets arxiv.org/abs/2609.26432

Just a couple hundred miles from Mexico's southwestern coast, Hurricane Polo strengthens even further. Polo has recently recorded a central pressure of 892 millibars, making it the second most-intense Eastern Pacific hurricane on record, behind 2015's Hurricane Patricia.
