Speaking of women in physics: Dr. Melba Phillips. Phillips earned her PhD on nuclear physics with Oppenheimer in 1933 & became a professor at Brooklyn College in 1938. A unionist, in 1952 she was fired after taking the 5th at a McCarthyist committee. She didn‘t get a faculty job again until 1962. 🧪⚛️

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.
The political effects of X's feed algorithm
https://doi.org/10.1038/s41586-026-10098-2

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 really good 🧵 RFK Jr plans to remove experts of a task force that decides what screening procedures are covered by insurance under the ACA. The USPSTF has been around since 1984. So typical of him to confuse evidence based decision making with “woke” . The propaganda does not stop.

This doc goes where Adolescence barely scratches. I think everyone, especially those who have teenagers kids.
Caught in the Net

It's a film that clearly and objectively shows just how vulnerable teenagers are online. While
"Adolescence" (2025) gets caught up in trivial things like emojis, Caught in the Net focuses on what really matters.
