The ability of the US to even pretend we have the moral high ground in any situation is pretty much gone for a generation, at least

Guess What Moderate Democratic Voters Arenโ€™t Anymore? Moderate. Two new polls suggest that moderate Democrats, too, want higher taxes on the rich and some measure of economic populism. Moderate isnโ€™t what it was in 1992.

Moderate Democrats with columns in newspapers are constantly saying the Democratic Party is way too liberal on "social" issues. Moderate Democratic voters in real life do not feel this way. With some polling data from @gelliottmorris.com and @dataforprogress.org. newrepublic.com/article/2074...

She's not taking any excuses and neither are we. Georgia, the state is on the line. Tuesday, March 10th-no "I forgot," no "my vote doesn't matter," no "I was busy." None of that! Get up and VOTE for Shawn Harris. On March 10th, you can make a difference! #GA14

AI error or not, Iran school bombing is a permanent stain on Americaโ€™s soul | Will Bunch A debate on AI in warfare obscures the truth about an Iran school bombing. U.S. humans are to blame for this war crime.

They had names. They had beautiful faces. And they had the same dreams as your kids - crushed when American "precision" bombs slammed into their Minab elementary school, killing 175

Don't blame AI for this. Blame the sick humans who see war as a game

In an Intense Election Year, New Post Office Rules Could Trip Up Voter Registration A change in how mail is postmarked could lead some voters to miss key deadlines, including voter registration. Advocates worry the people most affected will be those already facing voting barriers.

Many states require that mail ballots be postmarked by a specific day. But due to new USPS rules, voters may need to put their ballot in a mailbox days in advance.

There's something deeply obscene and broken about the fact that Donald Trump and Pete Hegseth are bombing elementary schools in an illegal war of aggression, and there's still a sense among the opposition that it has to be explained in terms of gas prices in order to get American voters to care.

Compact deep neural network models of the visual cortex Nature - Parsimonious deep neural network models can be used for prediction of visual neuron responses.

DNN models of the brain are getting bigger. Are we replacing one complicated system in vivo with another in silico?

In new work, we seek the *smallest* DNN models of visual cortex, balancing prediction with parsimony.

It turns out these compact models are surprisingly small!

Here is the "effective payline" for each institute, estimated (by Claude) as the percentile where one can expect 80% probability of funding from a logistic regression fit. The effective payline has gone from a historic ~12% to 6% in 2025.

Iโ€™ve spent years, decades, obsessing over the Bush Administrationโ€™s Iraq WMD lies, writing about them, debunking them.

I can think of no lie about Iraq WMDs told by Bush, Cheney, Rumsfeld et al that comes even close to the enormity and absurdity of this lie from Donald Trump.

Current NIH leadership want you to think they are using rigorous, consistent & scientific processes to screen studies to align them with agency priorities.

But the process that they have put down on paper is a sham.

Itโ€™s important to know NIH is not following its own guidance. Hereโ€™s why:

If you took $1 billion and gave it to the endowment of a different small college each day, they could each provide a free college education to several hundred students per year in perpetuity. Instead we are using that money to bomb schools and kill students in Iran, for no clearly stated purpose.

A new app alerts you if someone nearby is wearing smart glasses | TechCrunch A hobbyist developer's new app, which can detect nearby smart glasses, comes amid resistance to always-on recording and listening devices that invade people's privacy.

The recording light can be hacked and turned off. There is now an app to let you know when the glasses are being used nearby

ICO writes to Meta over 'concerning' AI smart glasses report Videos, including of glasses-wearers using the toilet or having sex, are sometimes reviewed by a Kenya-based subcontractor.

Last year when I was checking into a hotel, the desk person was wearing Meta glasses. I kindly asked them to take them off. They were annoyed. I said, โ€œI do not consent to you looking at my credit card and ID with Meta glasses on.โ€ My instincts were correct: www.bbc.com/news/article...
