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.

IOC as dumb as ever

Our lab will be boycotting biotech vendors that have contracts with ICE (e.g., Fisher, Agilent), and telling them why. If you google “vendorname usa spending”, you can see purchases for specific depts including ICE on usaspending.gov. Please talk to your labs and email your vendors!

Like the genetic code, bitcoin, or national borders, our methods for evaluating science are a "frozen accident": things that were formed from historical circumstances rather than careful design, and that persist not because they are optimal, but because replacing them is extraordinarily difficult.

In den vergangenen Tagen wurde auf verschiedenen Social-Media-Plattformen über die Vorankündigung diskutiert, dass die DFG zukünftig unter bestimmten Rahmenbedingungen die Nutzung von KI in der Begutachtung ermöglichen wird. Mehr⏬

Also einfach probieren bevor pauschal ablehnen!

Für life sciences gibt es den Tool von @qedscience.bsky.social . Es funktioniert eigentlich super: man erhält ein strukturiertes und sehr relevantes Feedback. Ich verstehe also die ganze Aufregung nicht: KI-Tools werden immer besser und als Hilfsmittel für die Begutachtung bereits sehr hilfreich.

Have you registered yet? Early bird registration and abstract submission are open until January 31.

Alleinerziehend in der Wissenschaft: Was Dauerstellen nicht lösen Ein Kommentar, angeregt von "Ziel erkannt, Ziel verfehlt?" von Amrei Bahr und Kristin Eichhorn

It’s clear we need alternatives or at least ways to improve the situation. So, together with a really special and talented team we worked to develop this idea into “qed” a platform where you can get CONSTRUCTIVE feedback on your own work or CRITICALLY assess other people’s papers.

On the left - western blot of B16F10 cells wt and KO for CDK8. Our in house produced antibodies give a lot of unspecific bands. On the right same probes with antibodies preincubated with fixed CDK8 KO cells - there is a specific band and faint unspecific bands, which can be probably eliminated with increase of amount of KO cells.

Neat trick if you polycolonal ab's suck. Incubate them with fixed cells with a KO of your protein of interest, then spin. Protocol here: www.med.upenn.edu/markslab/ass...
I was amazed how well it worked on first try (I'm sure that I can completely eliminate unspecific bands)

For anybody doing proximity-dependent biotinylation have a look at this reference preprint from the @gingraslab.bsky.social . Ten enzymes benchmarked in various conditions, it appears #ultraID is the enzyme of choice for combined specificity, speed and low background🧪

12 September 1924 | A Hungarian Jew, Tibor "Ted” Bolgar, was born in Sárospatak.

In June 1944, he was deported to #Auschwitz from where he was taken to other camps. He was liberated during a death march from Muhldorf.

Today he turns 101. Join us in wishing him a happy birthday.

Academic authors, here's a peek into the black box of journal publishing from an journal editor if you can bear it:

Well that's amazing.

Spent quite some time earlier this year to find Saturn with my old small telescope. Wanted to show my kids how cool the rings look. Was quite proud to find in spite of challenging background luminosity and then discovered that the rings are hardly visible this year….😔
