Here's an idea. Arxiv could peer review the papers and accept only those that pass peer review. Then even get an IF maybe! Insanity all around.

On the Navier-Stokes drama. From this exchange, I find OpenAI to be rather accomodating and I would interpret the "why would you damage your career line" as "by publishing something that is rushed, AI slopped and half baked". The request to drop Alpoge is indeed weird but I can see the complcation.

The model builds on ideas that were put forward by many before, and was sharpened by suggestions and criticism of many colleagues. I had initially drafted this idea in a 2018 preprint. The reviewers suggested leaving that concept for a review. Here it comes, 8 years later. doi.org/10.32942/X22...

I make predictions and hypotheses in the paper and explain how confident I am about each of them. I also apply the model to what we know about human sleep and, doing so, explain many apparent paradoxes linked to sleep length in humans.

Sleep is not one thing but a combination of processes with different elasticity. The vital component is life-saving and has zero elasticity; the useful component has some; the accessory component has the most, and lets sleep expand and contract in migratory birds, elephants - and us.

Giorgio Gilestro @giorgio.gilest.ro · 20/08/2026
Borrowing from economics, I introduce "sleep elasticity". The concept is Marshall's, 1890: essential goods like life-saving medicine and winter heating have low price elasticity, demand stays high as prices rise. Luxuries have high elasticity, demand drops sharply as prices rise.

Variability is not just between species, but also within a single animal. Some birds, for instance, sleep 16 or more hours during the winter and then go to minutes a day during the migratory & breeding season. They forego sleep almost completely for weeks or months. How is that possible?

Giorgio Gilestro @giorgio.gilest.ro · 20/08/2026
All animals sleep. This is something we have rightly taken as evidence of its importance. However, they all sleep in different ways and for different amounts, from 2 to 20hrs a day, something that speaks against a unified cellular phenomenon. In biology, variability is always key to understanding.

It was alleged that Jason Arday was an academic fraud mainly based on accusation of plagiarism initially moved by Nathan Cofnas. I have compared Arday's thesis with the one he's been accused of copying and found a bare 4.2% similarity.

An example of how useless X has become. 2020 Twitter would have been the place to go to get real time news on the war. Now it's 100% noise. Just old clips repackaged as new and an ocean of conspirationists talking to a crowd of blue checked clueless idiots. Incredible.

It makes it clear that immigrants are never going to be as good as native. They must speak English better than a native, earn more than 90% of natives, volunteer, and what else? Starmer's approval is lower than even Truss or Johnson ever was, and it can only go down. And it will.

Ashamed of the British government today. Once again politicians are ready to hurt the country's economy and social cohesion in order to try and get some more votes. Labour, like Tories, choose their seat first, putting the country second. This will be incredibly damaging in real terms and reputation

Dear US colleagues, can you please let me know if you are actually using these ridiculous evaluations you keep asking for? Are you aware that giving percentiles within a distribution is absolutely useless unless you know something absolute about that distribution? Such a waste of everyone's time.

PSA: #Google charged me £300+ for having generated 4-5 images in Gemini last month. Even though I have a paid subscription to the service as #gemini pro user. Try nano banana, they said. They should have pointed out the price is not included perhaps!? Goodbye Gemini.

My son's Microsoft account got hacked by some other kid. The best @microsoft.com can do is acknowledge the intrusion and show us the middle finger. Five years of progresses gone and buy the game again thank you very much. All this because their own security is sub par.

Gemini-cli is an utter joke. It's like the crazy cousin of Claude code. A complete disaster for me. Here I have asked to replace a js widget and it went on opening random files that had nothing to do then told me he cannot perform sexual stuff. Excuse me?

After a few tweakings, Musk finally got us a nazi Hitler apologetic that more closely aligns with the rest of the platform. All it needs is a more hatred towards black and trans. Has the line been crossed yet @imperialcollegeldn.bsky.social - what more do we need to see? Do we even have a redline?

Today, Starmer felt the need to go on X and reinforce his anti-immigration message and received so far 4700 replies. By the look of it, half call him fascist and the other half say "too little too late". Hope he realises how idiotic that move has been.

Looking at these many maps of Germany, all showing the massive segregation of eastern territories, I am reminded of all the discussions I had with economists back in 2013 when Piketty's book came out. They kept arguing inequality does not matter, as it's not a problem but part of the natural order.

It's too bad this big beautiful ocean was not discovered until recently. We would have avoided decades of cold war.
Think of it, a modestly successful comedian, Volodymyr Zelenskyy, talked the United States of America into spending $350 Billion Dollars, to go into a War that couldn’t be won, that never had to start, but a War that he, without the U.S. and “TRUMP,” will never be able to settle. The United States has spent $200 Billion Dollars more than Europe, and Europe’s money is guaranteed, while the United States will get nothing back. Why didn’t Sleepy Joe Biden demand Equalization, in that this War is far more important to Europe than it is to us — We have a big, beautiful Ocean as separation. On top of this, Zelenskyy admits that half of the money we sent him is “MISSING.” He refuses to have Elections, is very low in Ukrainian Polls, and the only thing he was good at was playing Biden “like a fiddle.” A Dictator without Elections, Zelenskyy better move fast or he is not going to have a Country left. In the meantime, we are successfully negotiating an end to the War with Russia, something all admit only “TRUMP,” and the Trump Administration, can do. Biden never tried, Europe has failed to bring Peace, and Zelenskyy probably wants to keep the “gravy train” going. I love Ukraine, but Zelenskyy has done a terrible job, his Country is shattered, and MILLIONS have unnecessarily died – And so it continues…..

A reminder to my American friends that eggs price is driven almost exclusively by viral outbreaks and that the USA are particularly affected because they still allow battery cages (outlawed in the EU in 2012). Trump complains but there are good reasons why the EU will not buy US farm products

Congrats to @sleepytit.bsky.social, now officially Dr. Sleepytit. Laurence is the latest and 7th PhD to graduate from the lab, with a great work on the use of ML to identify and characterise sleep stages in flies. If you are hiring data scientists, don't miss him. @imperiallifesci.bsky.social

NIH will likely reopen once the dust has settled and will comunicate that these are now the legal requirements to receive funding. There is a chance some specific research will be scrutinised and denied if it looks too woke. Here Musk was upset about using female rats, for instance. Good luck. 4/4

One of the executive orders Trump signed said universities will hear within 120 days from the Sec of Education on what are the requirement to keep receiving federal grants and they will most certainly have to prove not to be enforcing any kind of DEI policies on admissions or hiring. 2/4

If you are surprised about the sudden NIH blackout then probably you have not paid enough attention. This is a way to make sure any DEI initiative gets immediately annihilated. When Musk kept shouting that DEI must DIE, he wasn't kidding 1/4

It appears federal agencies cannot longer fund any research unless the institution can demonstrate they have no DEI policy in place. Speechless.

He spent the past year frantically sharing ultra right wing propaganda, he is a fervent supporter of the two largest fascist groups in Europe (ADL, BNP), he spreads antisemitic propaganda and messages. And let's not forget he is clearly mentally deranged 24/7. How can anyone still be in denial?
