Deaf 6-year-old boy is deported to Colombia without his medical devices, attorney says A Hayward woman and her two young children were detained and deported to Colombia after they showed up earlier this week for an asylum appointment in San Francisco, her attorney said.

Another tragic example of how Trump’s indiscriminate immigration raids are targeting the most vulnerable among us, including the family of a deaf child seeking asylum.

The cruelty is astounding.

Democrats join legal challenge to Trump’s planned 250-foot arch β€œThis is a straightforward issue of who’s in charge,” Sen. Angus King of Maine told The Post, citing a law that certain monuments must receive Congress’s approval.

New: Democrats asked a federal court to block Trump's 250-ft arch.

Under law, Congress must approve certain monuments in DC.

β€œThis is a straightforward issue of who’s in charge,” @SenAngusKing said.

They also mocked the "vanity" project.

β€œThis is not Pyongyang,” @RepHuffman told me.

My first thought was "There's milk in potato chips?" But it turns out that whey, a milk-processing byproduct, is used in flavored potato chips as a binding agent and to enhance taste and smell. Who knew?

Yes, vaccines πŸ’‰ can have adverse side effects, tho these are much lower than the risks of the diseases they protect against

What we tend to overlook is that vaccines can also have beneficial side effects, which can be surprisingly large πŸ§ͺ

NSF Intent to Restructure Critical Weather Infrastructure

The US NSF has put out a "dear colleagues" letter that is essentially a yard sale list for @ncar-ucar.bsky.social

It asks questions such as, who'd like to take over some of NCAR's programs? Is anyone interested in commercial use of the Mesa Lab?

A whistleblower just disclosed that FBI experts were delayed by AT LEAST A DAY in deploying to investigate Charlie Kirk’s assassination.

Why?

There was an FBI plane and pilot shortage… because Kash Patel was using them for personal flights.

According to an NPR investigation, the DOJ failed to release documents relating to interviews the FBI conducted in 2019 with a woman who accused Trump of sexually assaulting her as a child.

Only the first interview, is available to the public and she doesn’t mention Trump at all. trib.al/BU8zkFp

There's at least one witness for whom three 2019 FBI interviews are missing.

The hidden ICE blueprint that should horrify every American | Will Bunch An internal Department of Homeland Security document shows how ICE plans to cram thousands of detained human beings inside a Georgia warehouse.

What's more shocking than ICE's plan to cram as many 8,500 humans into massive, soul-crushing warehouses?

Seeing the actual DHS floor plan that echoes slavery ships and history's worst gulags with no rec space but a gun range for guards

The last part abt how measles disrupts immunity vs other infections is, imo, underappreciated (& mechanism was recently clarified). It's part of why measles vaccination was seen to help beyond just reducing measles complications - not getting measles reduces severity of subsequent infections too.

The political effects of X's feed algorithm

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.

New FAO publication describes global fish fraud and the tools to combat it All too often the seafood we eat is not what it says on the menu, potentially posing health and environmental risks.

This, from the Food & Agriculture Organization (FAO) of the UN suggests fraud in up to 20% of commercially sold seafood, including "counterfeit" shrimp made from starch and tuna dyed to look fresh. Also up to 1/3 of aquatic products sold in the U.S. "may not be what is written on the packaging." 1/2
