If Moderna is no longer bringing vaccine trials for Epstein-Barr virus (good evidence that EB causes Multiple Sclerosis), herpes, and shingles because of Trump appointees, I want prison time for those appointees.
This might be dooming millions to disease they don’t have to experience.

Gee, Universal Basic Income recoups more than it costs AND the recipients are happier and healthier.
Hmmm. Where have I seen those results before? Oh yes, in every other goddam pilot study of UBI for more than a decade. Ireland joins Finland in at least making a start.

There's a car parked in my neighborhood stuffed with amazon boxes. It's been there a while - I think it was buried under snow. Do I call the city in case someone's car got lost/stolen, or do I ignore it longer so I don't cause some poor delivery person a headache?

This is really interesting - there's a lot on potential 1A challenges, but the part mentioned about commerce is a fun read to scroll down to, particularly because it raises questions about the FACE act's worship parts overall. Also nice examination of whether there was impeding of entrance/egress.
NEW: Don Lemon is set to be arraigned this week on charges tied to a protest at a church.
The case has raised press freedom concerns. But the constitutional provision most likely to derail the indictment isn’t the First Amendment—it’s the Commerce Clause.

This is outrageous, and (though it was completely obvious he should never have held this spot), Vinay Prasad needs to go. This vaccine candidate deserves review, not ideologically motivated rejection. Lives are at stake. www.statnews.com/2026/02/11/m...
Prasad overruled FDA staff to reject Moderna's flu vaccine application
The rejection is the latest instance of Vinay Prasad overruling career FDA scientists to place vaccines under harsher scrutiny.

Q: Why do Black kids not do well in school, or in subjects like Math and Science?
A: This is only true in extremely racist countries. A racist person cannot teach a Black child effectively. It's not race. It's racism.

I had been pondering if Google Gemini had rendered Claude redundant and then I asked both to code review something I'd written.
Gemini: bunch of overly-enterprisy-feeling refactoring -which it then applied without asking-.
Claude: bunch of very reasonable and good suggestions as a nice list.
