Netflix Backs Out of Bid for Warner Bros., Paving Way for an Ellison Takeover

The richest man owns X.

The second and third richest men control Google.

The fourth richest man owns Facebook, Instagram, and WhatsApp.

The fifth richest man owns The Washington Post.

And now the sixth richest could soon take over both Paramount and Warner Bros.

See the problem here?

I'm not entirely sure how they did it, but they've completely cleared the streets around my office in Midtown #NYC.

They paid a lot of people good wages to do the job effectively, thank you for coming to my socialism talk

This article is incredibly damning of RFK Jr., as every single thing about him including his own actions and speeches and existence is.

This is the aftermath of an ICE kidnapping a few blocks from my home in St. Paulβ€”an hour ago. A quiet street full of broken glass and at least three wrecked cars. The target of the kidnapping was taken away by ambulance. He was on a stretcher and covered by a sheet, though a cop said he was alive.

Everybody has it backwards.

Billionaires aren’t buying up these institutions to make money. They’re buying them to kill them. Same as the oligarchs destroying government and social programs and things like weather forecasting and regulatory bodies.

They’re creating a world they control completely

My favorite thing in my intro astro class is explaining how small an arc second even is. Micro arcseconds (even ten of them) is bonkers!

Appeals Court Stays Restrictions on Federal Tactics in Minnesota
The Eighth Circuit granted the Trump administration’s request to block, at least for now, a lower court’s injunction limiting how federal agents interact with protesters in the state.

One court decision, two different headlines.

Guardian on the left, NY Times on the right. Which one more directly conveys information and the stakes to the reader?

This is your chance to tell the NSF how to fix itself.

Say no to the grift of AI datacenters. Say no to putting "quantum" where it has no business. Say no to false metrics. Say no to biotech scams.

Say yes to sustained investments. To fundamental science. To flagship facilities. To STEM education.
