So the US administration considers hate speech and disinformation “American viewpoints“? 🙄
HateAid is an organization that also helps climate scientists to defend themselves against online abuse and threats.
Its founder was awarded the Order of Merit of the Federal Republic of Germany 🇩🇪 this year.

Many people think about cold in Northern Europe if the Atlantic Ocean current system #AMOC fails. But that wouldn’t be the only problem for Europe by far.
This new study shows that severe drought is another one. 🌊

Shipping emissions levy shelved as countries bow to US pressure Long-planned charge on greenhouse gas emissions postponed as Trump officials accused of intimidation tactics

Wow, this is disappointing. This meeting was supposed to be a final confirmation of a deal agreed six months ago, and it would have been the first serious step in making the slow-to-change shipping industry cleaner & greener & ready for the future. The delay only hurts everyone in the long run. 🌊

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...

The Quantum Mechanics of Greenhouse Gases | Quanta Magazine Earth’s radiation can send some molecules spinning or vibrating, which is what makes them greenhouse gases. This infographic explains how relatively few heat-trapping molecules can have a planetary ef...

There's a really nice explanation (with clear graphics) in this @quantamagazine.bsky.social article of why most molecules in the atmosphere (oxygen & nitrogen) don't act as greenhouse gases, but a lot of the far less numerous ones (like carbon dioxide and methane) do. A great teaching aid :)

Quanta Series Marvels at 'The Achievement of Climate Science'

The simple machine that visualised atomic orbitals In 1931, Harvey Elliott White developed a device that traced out the shapes of electron clouds by approximating solutions to the Schrödinger equation

In the early days of quantum chemistry, before we had computers to calculate the shapes of electron orbitals, one man invented a mechanical machine that simulated their shapes. My latest column for @chemistryworld.com

The EU wants creepy AI to scan EVERY message you send. Even the encrypted ones. 😱

But guess who’s EXEMPT?

CERN Physicists Find Key Piece of the Matter-Antimatter Puzzle In a first, CERN physicists succeeded in observing matter-antimatter imbalance in baryons, fundamental particles that make up most of the observable universe.

New result from CERN (@lhcb.bsky.social) finds CP violation in the decay of baryons for the first time. Not unexpected - and not violation of baryon number itself! - but hopefully one more step in understanding why there is more matter than antimatter in the universe.

There’s a nonzero chance you will die from a cancer that could have been curable because people who couldn’t pass 7th grade biology and are scared of things like “mRNA” and “riboflavin” and “walkable cities” decided to make their ignorance everybody else’s problem

How did human language emerge? A key step was combining sounds into words, shifting from analog to digital to overcome error thresholds. Fascinating paper with deep ties to Shannon’s coding theory. @sfiscience.bsky.social

A study confirms what we have long argued: the spectacular Atlantic 'cold blob' is the result of a slowing of the Atlantic overturning circulation #AMOC, which transports warm waters into that region. That's the only part of Earth that resisted #globalwarming. 🌊

🚀 After two+ years of intense research, we’re thrilled to introduce Skala — a scalable deep learning density functional that hits chemical accuracy on atomization energies and matches hybrid-level accuracy on main group chemistry — all at the cost of semi-local DFT ⚛️🔥🧪🧬

Uncertainty in the face of serious danger is of course no reason to ignore it.
Passing that #AMOC tipping point by mid-century looks increasingly likely in light of recent studies.
And there’s also a more imminent, albeit a bit less detrimental risk:

Guess what? By learning from energies and forces, machine learning interatomic potentials can now infer electrical responses like polarization and BECs! This means we can perform MLIP MD simulations under electric fields!

Sadly, this is not the first time she has quoted Musk and Thiel. I first heard this a while ago, and it was the point at which, after almost a year of eye-rolling at some of her content, I finally stopped following her.
