1. If you claim "no vaccine in history was developed/approved as rapidly as the Covid vaccines" without having examined the timeline for the Salk polio vaccine, nor the technological advances that made rollout so speedy, you might be a #covidiot . nature.com/articles/d41586-0…

Incredible. First @SecMullinDHS claimed that @DHSgov identified 15,903 noncitizens on Nevada’s voter roll. Then DHS officials said, no no no, that’s just people we flagged, here’s the names of 185 people we KNOW aren’t citizens. All 185 were citizens. DHS got 100% wrong.
From 16,000 to 185 to Zero: Trump’s Claims of Illegal Voting in Nevada Fizzle. "The state sent a strongly worded rebuke to the federal government: Every single person on the list was a lawful citizen." nytimes.com/2026/09/24/us/po…

Trump’s obsession with these vulgar memorials to his own vanity is a reminder of the darkness around him, of his hostility to democracy, his loathing of honor, and his disordered mind. theatlantic.com/ideas/2026/0…

Apparently now a big result in number theory has been proven with the help of an LLM: Catalan's constant is irrational. arxiv.org/abs/2609.04176 Despite this I'm sure I will get lawyers and doctors and writers of romance novels telling me that it's all hype.

A new risk for mathematicians: a colleague reports that immediately after they posted an abstract of their upcoming talk online, a student elsewhere used AI to derive proofs of the stated results and then posted it on the arxiv. My colleague hadn't posted to arxiv yet.

Health Secretary of the United States is going to look into Chemtrails After that he will focus on leprechauns and unicorns What a fool
RFK Jr: "We are also looking at chemtrails"
Community note
RFK Jr. referred to "chemtrails," a conspiracy theory alleging secret chemical spraying by aircraft. No evidence supports this; trails are condensation (contrails) and a 2016 peer-reviewed survey of 77 atmospheric experts found 76 had seen none for such programs. epa.gov/regulations-em… iopscience.iop.org/article/10.108… statnews.com/2026/09/17/rfk…

The worst human being to ever occupy the office. Just reprehensible scum.
Trump on why it’s important for him to have his name the Kennedy Center: For me to go and fix it and subsidize it, I think the Trump Administration should have recognition. If we don’t do that, it’s going to close and get ripped down.

Closing the Kennedy Center is an affront to President Kennedy's memory, an attack on Congressional power and an outrageous assault on the livelihoods of the artists and workers who operate and perform in our cultural center. We're demanding it remain open and free from the President’s graffiti, vandalism and desecration.
Fencing has gone up around the main Kennedy Center building, a day after a Trump-aligned board voted to close it for repairs. apnews.com/article/kennedy-c…

The most effective way to survive cancer, is don't get "screened" for cancer. Just like the PCR tests for COVID and HIV, the cancer screenings are mostly false positives. And then they kill you with the treatment, just like HIV and COVID.

Donald Trump is the most corrupt president we've ever had, and it's not even close.
BREAKING: Donald Trump made nearly 29,000 securities trades in 17 months, more than every member of Congress combined, per Bloomberg. The stock-purchasing ban he’s pushing would also leave him exempt.

BREAKING: Kash Patel was busted with a cheat sheet of personal attacks against Democratic senators. Let that sink in: Patel came unprepared to defend his work. All he prepared was attacks. Evan Vucci/Reuters captured one page titled "DURBIN INFO," which is now going viral.
GTFOH! Kash Patel wants credit for releasing the EPSTEIN FILES while he was IN the Situation Room, the same bunker used to monitor Osama Bin Laden, to strategize how to cover up Trump's involvement in the Epstein files. The audacity is STAGGERING.

Why doesn’t OpenAI use an equal amount of the money they spend to prove interesting conjectures in funding PhDs in the mathematical sciences? That way we will have a next generation of researchers that can understand these results and formulate the next wave of conjectures.

Called it. When Caine said "no military," I said "So, ICE, then" And here we are, with ICE as a paramilitary force that will try to disrupt elections.
🚨BREAKING: DHS Secretary Markwayne Mullin said Tuesday that ICE agents could enter polling places to make arrests this November, raising fresh concerns about the Trump administration contemplating actions that federal law has long prohibited. democracydocket.com/news-ale…

This is literally not a fact and Joseph Ladapo should lose his license for the number of people he’s endangering
Dr. Joseph Ladapo says the hepatitis B vaccine's two approved versions were cleared by the FDA on less than a week of safety data. "That is literally a fact," he says. Del recalls @FLSurgeonGen telling him years ago he hadn't yet looked deeply into childhood vaccines, focused instead on the COVID vaccine while working under Ron DeSantis. Ladapo says his understanding has shifted since, crediting @AaronSiriSG's book "Vaccines: Amen" for laying out the data behind how widely used vaccines moved from development to approval. He calls the amount of safety evidence at the time of approval "horrific," describing it as "a very rotten scientific landscape."
