Just to recap, the actual president found an AI-generated video of a fake news report depicting a fake announcement about an imaginary healthcare system based on a technology that doesn’t exist and posted it on his official social media account

Wait: so the President of the United States shared a video of a fake news report, rooted in a conspiracy theory, that features an AI-generated version of himself promoting a policy that…doesn’t exist?

i genuinely think donald trump didn’t realize this was ai and thinks he said this himself

On Friday at Noon (EDT) I am giving a talk in the New York Combinatorics Seminar. The title is: "Mathematical illustration through a combinatorial lens" in which I share my decade-long journey as a mathematical artist and jewelry maker and how it intertwines with my combinatorics research.

Me: Which is why I did a Chotiner interview meme post Chotiner: but you did want engagement Me: Oh, of course! But it wasn’t just that. C: You felt you could add to the conversation Me: My own perspective. C: By posting the same joke as everyone else Me: it’s a funny variation

The thing about being neurodivergent is that I Like It. What I don’t like is that the world imposes numerous taxes on me for being like this. I don’t view it as a Me problem.

A fourth boat bombed in international waters. Total death toll now 19 What I dont get is, if these boats are "carrying fentanyl" as Trump says (they absolutely arent. Even the DEA says VZ doesnt produce fentanyl), then why not seize one and show us? www.miamiherald.com/news/nation-...

In these awful times for trans people I've found great comfort in the observation of a friend in her 40s who recently transitioned that 'my female friends immediately embraced me as one of their own and my male friends just became a little more gentle with me.'

This is so fascinating

“Harvard geneticist David Reich said … increasingly sophisticated analysis of genetic material made possible by technological advances shows that virtually everyone came from somewhere else, and everyone’s genetic background shows a mix from different waves of migration that washed over the globe.”

There is no world in which it is normal for the president to publicly call upon his attorney general to hurry up and prosecute his political foes. It’s like the Watergate tapes but posted on social media. Let’s get a grip on what’s happening here.

Must-read piece.

Trump just enacted the largest cuts to food assistance in history. Now he's cancelling the government survey that measures hunger in America.

My most Gen X complaint is that this question ignores our existence.

Maryland where you at? 👀

Anybody know why Maryland isn’t part of this?

Such a physical process, when sometimes we think of math as being disembodied.

Friends: I need recommendations for a kind of primer pushing back on RW/admin narratives on immigration. I have a lot of info but it's too in-the-weeds for a beginner. I need something 101, preferably with some larger historical background. Any ideas? 🙏🏻

I wish I were this brave! Well, I can aspire.

Ikr the queen of bad takes

"On the last episode of his show before he was killed," Kirk told "his audience, falsely, that “one in 22 Black men will be a murderer in their lifetime” and that “by age of 23, half of all Black males have been arrested and not enough of them have been arrested.”

Hey bug/arachnid people, what the heck is this? I was admiring some green shield lichen on a tree trunk in western Pennsylvania when I noticed a teeny tiny (.5 cm?) clump moving. I gently flipped it over, it’s something with legs?? Using the lichen for camouflage?

Charlie Kirk spewed so much hatred throughout his career it was impossible to include all of it in my story. And yet the mainstream media is largely whitewashing what he said and stood for. Stop supporting them. www.dailykos.com/stories/2025...

I feel like I've spent today sorting through accusations of this guy being a groyper, only to find that those aren't based on anything. There isn't an indictment yet. The cops haven't handled this better, but seriously—posting without verification makes you no better than the right yelling "antifa."

the new account created today with 6 followers and 0 posts and 12 replies that is replying to you with bullshit is a troll and if you aren't blocking on sight you lost the game cmon yall don't waste the energy, don't engage especially in other people's mentions

I say this with love but if you go around telling people that the regime has already fully consolidated power, you are doing their work for them. And you are also factually wrong.

ICYMI, this week I wrote about GPT-5 and the effort to stop LLMs from hallucinating, as well as saying they've done tasks they haven't. With web search to verify facts, finding citations is getting a lot better. But as soon as it's off, things can still go very wonky🧪🤖 www.nature.com/articles/d41...

Appreciate the original poster below for bringing this important and interesting event to my attention! I would genuinely love to see this! Someday, perhaps . . . . tramwm.wienerlinien.at/en/

I'm the same as Howie (just not as charismatic, charming, etc.)

This is next on my list

Charlie Kirk may have been good at showing up at college campuses and talking to anyone who would listen etc. But the org he headed built a database of professors to target with harassment campaigns in the hopes of drumming them out of academia. Is that practicing politics the right way?

Northern Ireland man from Lisburn kidnapped by Trump’s Ice raids because he “looked like a Mexican”. He had the correct visa, all his documents. He’s never been in trouble with police. Held in terrible conditions. A fellow captive couldn’t get his medication and dropped dead of a heart attack
