As someone that teaches biochem, this is very painful
Original (left) and corrected (right) Fig. 4a in the paper https://www.nature.com/articles/s41586-026-10305-0 showing the chemical structures of amino acids (only the right one) the left figure is just an embarrassment
I wonder... 🤔🤔🧪 #chemsky
a) what program did the authors use to make the original (left) figure in the paper? Wild guess, ChatGPT
b) how such high school science level of disgrace pass peer review in @nature.com?
Note this was Fig.4.a NOT in SI

This is madness.
This is equivalent to evacuating large parts of Paris or Houston. Where are all these people supposed to go?

NEW: Wikipedia editors have implemented new policies and restricted a number of contributors who were paid to use AI to translate existing Wikipedia articles into other languages after they discovered these AI translations added AI “hallucinations,” or errors, to the resulting article.
FT comments section this morning - saying what everyone else is thinking, right?
Again: Not hyperbole, misinterpretation, or a joke that Christian Dominionism is a strain of apocalyptic accelerationism which VERY LITERALLY SEEKS to hasten their vision of the Biblical end of the world, & the people who believe this have VERY CAREFULLY worked their way into the halls of U.S. power
With Eugene Koonin, we propose a concept of “the selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268

Today’s military strikes on Iran — carried out by the United States and Israel — mark a catastrophic escalation in an illegal war of aggression. Bombing cities. Killing civilians. Opening a new theater of war.

Finished reviewing a paper today. I did it by reading the paper, thinking about it and then writing my report. All natural intelligence. No artificial additives.
Brainwashing, 2026 edition. This paper shows how X's algorithmic feed shifts people's views rightwards. It's a sophisticated, highly effective form of reorientation. And it is utterly chilling.
If you're still on that platform, unhook yourself now.

The political effects of X's feed algorithm https://doi.org/10.1038/s41586-026-10098-2 Received: 16 December 2024 Accepted: 4 January 2026 Published online: 18 February 2026 Open access • Check for updates Germain Gauthier,5, Roland Hodler?5, Philine Widmer35 & Ekaterina Zhuravskaya3,4,5 m Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects. Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.
A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.
Moving from chronological feed to the algorithmic feed also increases engagement.
This is one of the most concerning papers I’ve read in awhile.

This sounds really interesting! Indicates more structural coordination inside the HIV capsid than previously thought. The paper has some though-provoking discussion on reverse transciption in light of this. Congrats all authors!
