Good morning with good news: An historic energy milestone is reached. Renewables globally produced more electricity than coal for the first time on record in the first half of 2025!
How?
Solar skyrocketed 31%
Wind rose 7.7%
Coal FELL in China & India!

I don't submit often to NeurIPS, but I reviewed papers for this conference almost every year. As a reviewer, why would I spend time trying to give a fair opinion on papers if it's what happens in the end???
As an SAC for @neuripsconf.bsky.social, I don't agree with PCs approach to reject papers based on ranking.
I ranked my accepted papers as requested and explicitly stated that I support the acceptance of all papers.
I was not given an explanation of why papers at the end of the rank were rejected.
Which work? Calling for gay people to be stoned to death? Blaming airplane crashes on black pilots? Anti-vax bullshit? Election denialism? Pushing Great Replacement Theory?
Kirk’s murder is awful and ominous for this country. But no, we don’t need to honor him or “continue his work.”
10/ This is the structural change we’ve all been waiting for. Emissions are plateauing. Coal is peaking. The export of clean technology by China is doing more to decarbonise emerging economies than any Western climate summit or speech.

These lengthy forum style comments are a nightmare: a nightmare for the authors who spend way too much time writing them, a nightmare for the reviewers who spend too much time understanding them, a nightmare for the ACs who will have to summarize all. Stop it!
New blog post: AI Allergy.
On my increasing disgust with the AI discourse, even though I still like the technical and philosophical. And how I wish I could be excited about AI again.

I have found ACing for NeurIPS this year a miserable experience and I've been struggling to articulate why without basically whining about it being too much work (although.....true. My god the amount of words I'm reading...). But I think I've figured out part of my dislike for this process.

EurIPS is coming! 📣 Mark your calendar for Dec. 2-7, 2025 in Copenhagen 📅
EurIPS is a community-organized conference where you can present accepted NeurIPS 2025 papers, endorsed by @neuripsconf.bsky.social and @nordicair.bsky.social and is co-developed by @ellis.eu
eurips.cc
🌍 Would be better if authors were allowed to present at officially endorsed hubs or online instead — ensuring fair and equitable participation, and ultimately creating a better NeurIPS for everyone.
Interesting in knowing more: read our full opinion piece ⬇️. docs.google.com/document/d/1...

Today marks a big milestone for us at Emmi AI. We’ve raised a €15M seed round, backed by 3VC, Speedinvest, Serena, and PUSH. Let’s build the future of Physics AI together!

French researcher, going to a conference in Houston, was forbidden entry to US; his work and personal electronics were both confiscated.
Why? Because a “random search” of his cell phone revealed a negative personal opinion on Trump and the Trump administration. www.lemonde.fr/internationa...
AI generated summary for whether hippos are intelligent animals. Says that Hippos can learn medical procedures, such as ultrasounds, to help monitor their health.
Hippos are legit amazing tho.

I have been doing entirely too much earnest posting about deep things recently, I need to do a proper thread about hippo testicles or something just to keep myself sane.
Oh by the way hippos have migratory testicles.
I mentioned earlier that they chew on Nile Crocodiles - I wasn't kidding, baby Hippos use them as teething rings since the texture of their scales is satisfying to gum.
Just this 12' long razor-toothed archosaur, sitting there going "stay calm, Clarence, you survived the asteroid, you can do this."
I wrote about why funding for the NSF and NIH is important to me and to my hometown (Charlottesville, VA) at @cvilletomorrow.bsky.social. Thank you to @sciencehomecoming.bsky.social for inspiring me to do this!

"We at @nature.com denounce this assault on science. And we encourage the global research community, wherever they can, to voice their opposition."
+1 to this. Overall a very good read to help the science community focus our energy 🧪 www.nature.com/articles/d41...

MESSAGE to the NSF Pl Community, Office of Management and Budget (OMB) Memorandum M-25-13, issued on January 27, 2025, directs all Federal agencies to conduct a comprehensive review of their financial assistance programs to determine programs, projects, and activities that may be implicated by the recent Executive Orders. Therefore, all review panels, new awards, and all payments of funds under open awards will be paused as the agency conducts the required reviews and analysis. NSF has created an Executive Order Implementation webpage to ensure the widest dissemination of information and updates. We will continue to communicate with you as we receive additional guidance. All NSF grantees must comply with these Executive Orders, and any other relevant Executive Orders issued, by ceasing all non-compliant grant and award activities. Executive Orders are posted at https://www.whitehouse.gov/presidential-actions/.In particular, this may include, but is not limited to conferences, trainings, workshops, considerations for staffing and participant selection, and any other grant activity that uses or promotes the use of DEIA principles and frameworks or violates Federal anti-discrimination laws. Please work with your institutional research office to assist you in complying with the Executive Orders. You can also direct your questions through the form on this NSF webpage. Thank you for your work advancing science, engineering, technology and innovation for our nation. Sethuraman Panchanathan Director
Received this e-mail from the NSF this morning.
The webpage it directs you to for submitting questions doesn’t give you any way to receive a response; when you submit a question it says “Your response has been submitted” and claims that they’ll put together a FAQ page.
Congrats to Mario 👏 for the accept of his ICLR paper on "Diffusion Graph Nets", it targets predicting complex distributions of flow states on unstructured meshes openreview.net/forum?id=uKZ... It works even if the training data contains only a fraction of the flow statistics per case.
