Plasma physics, mostly via kinetic simulations on supercomputers. I occasionally (but not actually every day) post a "Paper of the Day" #potd that may or may not be related to my work.

Just realized one reason the right wing went so far into the anti-vax direction is that the covid vaccine, more than pretty much anything else of late, showed what can happen when government works hard on something. Govts delivered a vaccine to a new disease in, what, a year?

The White House is taking new steps to undermine every international student at our universities.

It has approved a new rule restricting student visas to 4 years max. That's not long enough for PhD students, or about half of undergrads, to finish their degree.

Likely to enter force within days.

I see the first articles in the UK press giving space to the claim that 3I/ATLAS is an alien spacecraft. Briefly:

It’s a comet that formed billions of years ago, passing through our Solar System.

It’s behaving like a comet.

There is no evidence it’s artificial.

So much this. Letter counting and state names are gimmicks, not primary use cases. Frontier models are already remarkably capable for many quite difficult tasks despite still, of course, failing in important ways. We should be able to recognize this fact without uncritically accepting industry hype.

So many researchers, myself included, work many more hours than what we are funded (i.e. it's not uncommon to work 10hrs/week on a project that we're only getting 10% salary support). Rest-assured--NIH grants are NOT lining ANYONE's pocketbooks. Dumbass. #academicsky

My goto is to ask LLMs how many states have R in their name. They always fail. GPT 5 included Indiana, Illinois, and Texas in its list. It then asked me if I wanted an alphabetical highlighted map. Sure, why not.

This is about more than research. These grants are the lifeblood of one of the country’s biggest industries. They determine promotions and professional success. More than 1m educated, high-status people will change their daily, personal, private behavior to avoid angering these commissars.

I am so embarrassed for humanity.

We had this disease eradicated. The process of keeping it that way was SO SIMPLE.

And because of a bunch of idiots, and bunch of grifters making public health into an ideological football, here we are.

Just a faceplant. A completely unforced error.

It gets worse and worse.

If you're interested in the slow-motion train wreck that is Avi's sci-comm on this, here are some of the latest (it's very hard to keep up!)

It has been brought to our attention that some sections of Article 1 are missing from the Constitution Annotated (constitution.congress.gov) website. We’ve learned that this is due to a coding error. We have been working to correct this and expect it to be resolved soon.

Possibility of hundreds of job cuts 'unsettling' for CSIRO staff The CSIRO is facing hundreds more cuts to staff, after more than 400 jobs were slashed last year, the union has warned.

It really would be nice to see the #Australian government genuinely support #science. Cutting jobs at CSIRO is madness. Research in the university sector is also critically underfunded. If only there were some tax loopholes that could be closed... #academicsky

How to alter the passage of time to feel fast or slow | Psyche Guides Knowing the psychology behind why moments drag or whizz by can give you a degree of control over your experience of time

πŸ‘‹ Hi! Time Perception researcher here. Emotional time dilation has been studied pretty extensively with some neat findings. (I recognize OP was meant as joke but this is what I do). Check out my recent Psyche article if curious psyche.co/guides/how-t...

As a physicist I can easily calculate time dilation from relativistic motion (time slows when you're moving fast) or proximity to a massive object (time slows in gravity) but I have yet to find a solution for emotional time dilation (the task takes five minutes to complete but six weeks to start) 🫠

Headline and first 2 paragraphs 

Migrants can use rights laws to evade deportation


Loopholes could undermine treaty with France
Matt Dathan Home Affairs Editor

Small boat migrants will be able to frustrate attempts to deport them to France under Sir Keir Starmer's returns deal by exploiting human rights laws, according to the treaty's terms.
Under the terms of the agreement with France, migrants will be ineligible for deportation if they have outstanding human rights claims or other legal challenges or claim they are under 18.
These are among potential loopholes that threaten to undermine Labour's attempt to end Channel crossings. The treaty also gives France and other European Union member states an effective veto over which individuals are returned.

Just the supposed β€˜paper of record’ bemoaning the fact that asylum seekers have *human* rights and may be able to enforce them. Accompanied - ultra cynically - by a photo of Human Rights lawyer, Amal Clooney, at a glamorous fundraiser. What a sly and deeply unpleasant rag The Times now is.

A new study finds conservatives are more likely than liberals to accept AI-generated recommendations, especially when AI appears to know their past preferences.

In case you're wondering how scientists can say that many shark populations are threatened with extinction while some US fishermen report that they've never seen so many sharks, the answer is shifting baselines: how much things have changed depends on when you start counting.
